Spectrum analyzer data is b0rk (either that or else the example WA plugin only draws 1/2 of it):

Image <-- Look at built in vis and compare

/me is looking into it

Silly me, the example vis only draws 1/2 of the spectrum :B

I checked back w/ foosion and he suggested to look at foo_vis_vu_meter source instead because he solved the problem in a less messy way there.

source is buried somewhere here

Hmm, foosion's page currently isn't coming up for me, but I'll look at it when it does.

kode54, I'm going to have to agree with you that we need some sort of synchronization before releases... I'm just not sure what the best way to do that would be. Hmm :/.

Some type of CVS system, but this plug-in is to small of a project to be housed on SourceForge!

I'm not sure CVS is necessary... just some way of getting the changes planned for the next release established so people don't keep having to download the latest build and merge all of their almost-completed changes into the new source. The release frequency has slowed down a lot, though, which helps with that.

Simply put, the vis is kept open as long as it is enabled, whether it is receiving audio or not. In that case, it might be wise to update the wannabe deque class to keep track of how many samples are in its buffer, subtracted on every read() operation, and if there isn't enough for read(), fill the output with zeroes... or maybe notify the caller and it can stop rendering frames until there is enough... Meh.

Hmm, I don't know. It'd make full-screen visualizations slightly more annoying because they'd have to be manually exited when playback stops. On the other hand, the timer is kind of messy, so eh.

As for the deque, I think it'd be enough to just fill it with zeroes on flush if we left the window open (it would effectively accomplish the same thing). To be honest, I've never been huge on the deque as a way of keeping exact synchronization (it just doesn't seem like it should work even though, as it turns out, it mostly does), but the code was so simple that I haven't looked very hard into coming up with a new solution. I'm not even sure there really is a way to keep everything exactly synchronized anyway.

Especially considering that even in Winamp itself, the vis just runs on its own in its thread, while Winamp fills the vis sample/spectrum buffers whenever, all without any synchronization whatsoever.

Their "API" sucks.

...and the first time they attempted a rewrite from scratch, the majority of developers avoided it. Of course, it wasn't really designed to be easy to program for...

A) somehow i can't get 0.389 to compile: i get several dll-manager-related link errors.

B) kode54's interpolated spectrum is more informative but i think what we got to achieve is a spectrum that looks exactly like the one winamp would give them if we want the plugins to run like in winamp. i hope it is possible: i got the impression the vis-data sent by by foobar is of much worse quality than winamp's.

C) on my machine bacon does not really run fluently. even with the cheapest winamp-plugins. i got 1600 mhz so i don't really understand why. i think it's not the interpolation. what else could it be? does it run like in winamp on your machines?

D) maybe the project should be split into more files so everyone works on a different file and only this file is to be updated!?

A) Hmm, weird. You did add dll_manager.cpp to your Visual Studio project, right? Out of curiosity, what kinds of errors are they?

B) We can't get it to look exactly like Winamp's simply because we don't get exactly the same number of data points. I'm not sure I'd say foobar's data is lower quality, but the number of spectrum points is indeed lower, so we can't really tell what would go there unless we somehow tried to calculate spectrum values ourself (messy and probably not worth it).

C) It may be a bit slower on my machine (933 MHz Pentium 3), but it's not that bad. When you say it doesn't run fluently, do you mean that if you use, say, the Winamp example oscilliscope plugin, you get visualization stuttering? That'd be something to look into :|.

D) Well, I'm not sure if that would help with synchronization or not, since it's very possible that we'd all make changes in the same file in the process of doing different things, but I think it may be a good idea to somehow split up foo_vis_bacon.cpp. It's gotten pretty huge.


While I'm posting, does anyone have any ideas for stuff to go into the next release besides miscellaneous code clean-ups or bugfixes?

Runs perfect here.

AthlonXP 1500+

So in other words the data sent to the VIS is not as updated in foobar2000 as it is in Winamp?

i switched to 0.8 final sdk and now it works. i got no idea why...


i didn't mean the number of data points. one and the same song produces much higher spectrum-amplitudes in winamp. either winamp postprocesses vis-data sent to a vis-plug or foo's and wa's decoder makes that difference.


it seems to me as if winamp-plugs run with bacon refresh half as often as in winamp. i suppose foobar does not send vis-data as often as winamp. the stuttering i have is like you work on a high-memory-load machine. 1-2-3-hang-1-2-3-...


that's a good idea.


i think we should focus on the vis-data problem first.

This is from the 2nd thread looping without sleeping to check the time. I stuck a Sleep(1) in and that reduced CPU usage on simple plugins by about 1/5 here.

Here we run into one of the several issues in translating foobar2000-style vis to Winamp-style vis.

Foobar's visualizations are either tightly synchronized to or part of the main thread (my memory tells me it's the latter, but I'm not certain). Foobar calls a certain number of updates per second. This allows foobar to control the FPS of the visualization. Because it's doing this, it can also fourier transform the data to obtain the most information possible. We may be able to get better results by transforming the PCM data in Bacon itself rather than relying on Foobar's fourier transformer. I'm a little skeptical that coding our own transform will be worthwhile, because Peter appears to use the best code possible for the job wherever possible.

Winamp, on the other hand, has much less structure. It shows the plugin where to find the spectrum/osc data, and relies upon the plugin to call it at will. The input plugins are tied tightly to the spectrum data to provice raw information about the current frequencies.

The short version of this is: Foobar refreshes the spectrum data at intervals. Winamp refreshes the spectrum data constantly. Due to the intervals, Foobar's visualization can appear "jumpy".

Thus, we need bilinear interpolation on the spectrum data: interpolate between both the frequencies retrieved and the packets of frequency data. This means we may need to buffer one "frame" of spectrum data so that we can interpolate nicely.

It might also produce an ugly effect, but perhaps we also need to keep track of how many samples are left over in the circular buffer(s) and linear stretch them to fill Winamp's buffers upon request. Of course, this will probably produce a much worse effect than the stuttering seen when the Winamp vis renders a frame or two without a sample/spectrum update.

Hmm, I'm really not noticing any stuttering. Maybe my machine's slow enough that the lack of synchronization gets smoothed out. Would increasing the visualization framerate in the foobar2000 settings help with this? It'd be closer to continuous updates... at the expense of hogging your CPU :/.

The only other way I've thought up of getting samples over to the other thread would be to buffer a lot of them, then figure out at which point in the present buffer a Render to Winamp would fall and pass that interval of samples, throwing out any samples too old to be used in the process. Thing is, the current method of having the foobar2000 main thread stream samples through a buffer and then the Winamp plugin thread grab snapshots does the same thing in principle and the code is simpler, so it's a question of whether, "in principle," is good enough or whether we should try to get everything perfectly lined up.

@hartwork (on the spectrum data height issue) :
I think I may just start running test tones through both programs and seeing what kind of spectrum values I get because we really should know how both programs generate the spectrum data and, at the moment, I don't.

@Canar:
You know, you may be right about this. The Winamp plugins are only getting 576 samples, while the foobar2000 spectrum is being calculated for however many samples are in each batch (which seems to be something like the sample rate divided by 45, though we really can't make any assumptions about it), so it's possible for the same spectrum data to be handed out for different samples.

@kode54:
I'm not sure what you mean by, "left over." The samples aren't getting thrown away, so if the Winamp plugin calls a lot between foobar updates, it'll just get the same data.


See, this is why I had hack warnings all over when I posted the first build (well, that and the crashing :B ).

"Left over" assuming that on_data is getting more samples than the vis thread can handle. Of course, stuttering would only occur if the vis is swallowing samples faster than they are being updated.

The sample count will always be the sample rate divided by the vis frame rate, I think... I'm not sure about the number of samples fed to the FFT library.

Works fine here in both Windowed and Full Screen modes. It stutters big time in Destop mode though. Tried running Milkdrop in Winamp as well, and same thing happens in Desktop Mode. Using Geforce 2 MX400, Athon 2000 with 512 DDR 2700 RAM. Running Win Server 2003 with DirectX 9.0b.

you might wanna ask around the vj forums

personally i'm stuck between loading exisiting visualizations (avs, milkdrop) or getting some new kick-ass plugin

I am probably missing something here, but I downloaded foo_vis_bacon.dll (-0.389) and put it in my components directory. When I select BACON from the components context menu the console comes up with: "ERROR (foo_vis_bacon) : Couldn't load DLL". What am I doing wrong?

Which Foobar version are you using?

You're getting that error because you haven't yet configured foo_vis_bacon to use any Winamp plugins. If you go into the configuration menu, direct foo_vis_bacon to a directory with Winamp visualization plugins in it, and select the plugin you want to use from the combo boxes there, things should work.

Ok, now I configured bacon to point to the plugin directory and selected the one I want from the pulldown menus. Now I go back to select BACON from Components | Visualizations and I get the same error. Using foobar2000 v0.8 final.

version minus038. [binary][source]

spectrum looks much more like winamp now. i implemented to different modes: one with interpolation and without. we just got to decide which one to choose (or give the user the option to choose at config). compiled version uses the interpolated one.


WITH interpolation (upper = foo, lower = winamp)


WITHOUT interpolation (upper = foo, lower = winamp)


the screenshots are from my last nullsoft-vis-minisdk-mod which displays all 576 spectrum entries. download it HERE.


sorry, but i haven't split foo_vis_bacon.cpp for now...

Hmm, I can reproduce this if I don't touch the drop-down menus (meaning I leave it as the default choice), but as soon as I bring up the drop-down menu and select a new plugin, it works again. If you actually mess with the combo boxes, does the problem persist (and also if you restart foobar after messing with the boxes) ? If you still have problems, I can probably get you a build that prints the filename of the current plugin to the console (or, depending on your programming knowledge, you could try it yourself, too :).

I'm starting to question the overall practicality of maintaining this Winamp-style combo box selection dialog given the variable plugin directory. I wonder if having the plugins selected individually by a file open common dialog box might be better... :|.

I also tried adding another winamp plugin to the specified directory and chose it from the bacon configuration screen. I then selected bacon from the context menu again, but nothing happened so I attempted to close foobar2k and my entire machine locked up forcing a hard reboot (damn, haven't had to reboot in over a month, WinXP SP1).

This isn't meant as a complaint (I understand this is very early development stages), just trying to get it to work...

WTF :/. I've noticed the issues with bacon sometimes not enabling if you reselect it; I need to look at the source and see which variable isn't always getting set properly, but it really shouldn't be locking up. I guess you can try starting foobar again, going into the configuration dialog and making sure the plugin you want is selected, then closing the configuration dialog, starting playback, and enabling bacon in that order and see if the situation improves, but this is really weird.

As for not being a complaint, well, it should be, since it's evidence of the current behavior simply not working intuitively. I'll look for a bugfix and add some more console info at some point, I guess.


Oh, and thanks for the spectrum work, hartwork .

Ok, got it to work. Not quite sure what I did (combo of messing with combo boxes, selected BACON from context menu, and restarting foobar). Anyways, really cool plugin, thanks.

(now I gotta rebuild all my playlists that seemed to have disappeared after the crash ).

Or, vis_bacon can do the analysis by itself and look even more like Winamp :B I may look into using something like FFTW or something for this if I have time

for the mean time,

geiss is availible as a screen saver and works with foobar2000 very well

I use it a parties, screen save set to 1min

avalible at http://www.geisswerks.com/

enJoY !!

Can I be a pain and ask for a new feature?

I have a server and media pc at home, the latter is in the lounge and the former is in the office. Foobar autoloads on the media pc and the vis (milkdrop) is on by default.

Sometimes if I go to the office down the hall, I want to change the tune playing on the media pc. So I Remote Desktop or VNC in and change via the Foobar gui. Problem is, the plugin detects a screen change and comes up with a dialog box saying it can't find Direct X, probably because it's not supported over RD. You can't get rid of these boxes, you have to kill Foobar.

Is it possible for the plugin to detect RD or VNC (I think there's an API, other programs do it) and gracefully shut down the vis? I can dig out the relevent API docs if you like.

Thanks for a quality plugin,

sean

Synesthesia doesn't seem to be playing nicely. I'll see if I can figure out what it's doing. If you'd like to experiment with other Winamp plugins, try renaming vis_synesth.dll to something like vis_sysnesth.b0rked until I or someone else finds a fix.

[EDIT]: Grrrrr.... the call to winampVisGetHeader is blowing something up and I don't know why. It'd probably help if I could get the Synesthesia source to build :/.

Boomp. I've figured out what caused that crash and the problem isn't with foo_vis_bacon, but rather with the general ugliness of its purpose.

PhrostByte, here's how to get Synesthesia to work:

1. Create a new directory called Plugins in the same directory as foobar2000.exe. The directory for vis_synesth.dll has nothing to do with this.
2. In that Plugins directory, create a file called synesth.log. Without this file, Synesthesia will crash. Why? Because it doesn't bother to check whether the file pointer for the log file actually exists or not and because it doesn't create files to open them; it only appends.
3. Next, copy the program synconfig.exe, probably already installed your Winamp directory (Winamp main directory, not the Plugins directory), into the same directory as foobar2000.exe (again, not the Plugins folder). This is necessary to configure Synesthesia and therefore to get it to select any plugins.
4. Go into the Synesthesia directory and make sure the ini file and Sonique vis directory paths are correct. I really don't know why these point to Winamp for me when the other paths here don't :/. If you don't have Winamp installed, I'm not sure what these paths will look like... you may need to create empty text files manually with the same names to avoid more crashing, but it's hard to say.
5. Please configure Synesthesia before trying to use it.


If anyone else gets crashes with vis_synesth referenced in the crash log, take a look at these instructions.

I hope this helps >_<

No, it's not the ugliness of its purpose. Don't blame yourself. Blame the idiot who wrote that software. I suppose you can't really blame Nullsoft for writing a crappy API, as they didn't know much then, did they? Hmm, maybe they don't now either. Then, blame all the idiots that Nullsoft didn't dare alienate by ever breaking that API to make it cleaner. Then blame them again for rejecting the first and only attempt by Nullsoft to rewrite that API from scratch. Oh wait, haven't I already said this?

Hey cool thanks a lot bleh. I've got a new problem. I ran climax and now I can't close it without crashing foobar. Log:

But oh well, as long as geiss's plugins work I'm a happy boy.

Ooh, fun. More crashing plugins!

...

Eh, debugging this is easier than trying to deduce how this FFT stuff works from whatever pages Google barfs up :/.

[EDIT]: It doesn't crash for me, but it does try to kill foobar and then lock up. I wonder what it's doing.

[EDIT EDIT]: Instead of creating its visualization window as a child window like it's supposed to, Climax makes its own standalone window and then probably uses some weird hack. I managed to crash Winamp with it, too. I'm really not sure what else I can say about this plugin except that it's probably not worth using.

Yeah.. it isn't.. I was just testing stuff out, but yea thanks again

Yay, bugfix release (version minus0.37).

Source (requires the KISS FFT library to compile, but I may decide to distribute that along with this at some point.
Binary
The infamous MSVCR71.DLL. Put it in the same directory as foobar2000.exe if you don't already have it. This is only necessary for builds I release since my version of Visual Studio is too new - binaries from kode54 and hartwork should be fine without it.

What's new (-ish):

• If the plugin fails to start up, it should turn itself off and then resume trying to work normally the next time you try to enable it (bugfix).
• If you enable the display of debug messages, the filename of the DLL being loaded to do visualization will now be displayed, which should make it easier to debug weird problems where you think you've got everything configured properly but it still tells you the DLL won't load.
• Fixed irritating bug where foobar2000 would hang if you tried to close it without stopping visualization first.
• Spectrum data is now calculated for the samples being sent to the Winamp plugin using KISS FFT; however, the resulting spectrum still doesn't look like the one Winamp generates. Joy! I would have held off on releasing this until I figured out why this is happening, but I considered the above bug serious enough to justify shoving a build out the door.
• I started splitting up foo_vis_bacon.cpp, but then got lazy and stopped :/.

Thanks for the update bleh. Hope you can get the spectrum data thing worked out.

can someone please make a tutorial, or compile appropriate versions of plug-ins and files that would allow me to get milkdrop/bacon working in foobar. Ive tried and tried, but I keep get an error message saying bacon cant be initialized. Any help would be greatly appreciated.

Chris

I'm too lazy to put together a web page now, but here's a brief summary:

1. If you do not have Winamp installed, create a directory somewhere to hold your Winamp plugins and install a bunch of Winamp plugins there. I don't know if you do or not, but if you don't have Winamp installed and you're having problems with this step, let me know and I'll see if I can make it easier for you... some plugins require extra effort to install without Winamp (I should make a list or something :| ).

2. Download the binary linked to in my earlier post and extract foo_vis_bacon.dll to your foobar2000 components directory.

3. If you do not have Visual Studio .NET 2003 installed on your system, you'll probably also need to download MSVCR71.DLL (also linked to in my previous post, though it is zipped), and put it in the same directory as foobar2000.exe. Without this, you'll get error messages about not being able to load foo_vis_bacon.dll, which I suspect is what happened to you, but I'm not sure.

4. Go into the foobar2000 Preferences menu and select. "Baconwrap," under the Visualizations group. Ignore any messages about not being able to find any plugins for now.

5. At the top of the foo_vis_bacon configuration screen is the directory currently being scanned for plugins. If you have Winamp installed, this should hopefully be pointing to your Winamp plugins dir. If not, you'll have to click the ... button and select the directory to search. For now, it will only detect Winamp plugins named something like vis_PLUGINNAME.dll, but I could decide to make this an option for people who really like having every DLL in a directory scanned. If you get an error message after selecting the directory here and you're certain you have plugins in it, let me know.

6. Next, look at the two combo boxes below it. The top combo box tells you which plugin is currently being used. If you drop it down, you should be able to select Milkdrop without any problems. The combo box below it is for setting the plugin module to use, which is useful for some plugins like the Nullsoft Tiny Fullscreen visualization, but doesn't matter for Milkdrop because Milkdrop only has one module.

7. Once you've selected the plugin you want, you can configure it by clicking the, "Configure Module," button. It should bring up the configuration dialog for the plugin exactly like in Winamp.

8. Now that you have everything all configured, close the preferences dialog. In the main menu, check to Components -> Visualization -> Bacon. That should make foo_vis_bacon run whenever foobar's playing audio.

9. Play something and see if it works.


Also, for anyone who's wondering, the reason I haven't released an update recently is that Winamp's spectrum analysis confuses me, possibly because I don't really know anything about spectrum analysis. If I feed it, say, a 1500 Hz sine wave at a sampling rate of 48000 Hz, it should produce a single, vertical line, since 48000 / 1500 = 32, so the sine wave gets repeated exactly once every 32 samples. This is what I get from the FFT, foobar's visualization, and Winamp's MP3 decoding plugin. However, the visualization Winamp uses for WAV files and other stuff displays absolutely nothing at all. I feel like I missed something.

thanks...I got it to work..only now I have a large problem. After playing for about 2 mins with Milkdrop on fullscreen, my computer freezes! Ive tried this both in Winamp and Foobar, and it hapens with both....nyone have any dea what the problem i?

Hmm, that's kinda weird. You might want to look at updating your video card drivers or upgrading DirectX if you have a really old version. I suppose it could also be a corrupted Milkdrop installation. Do you have any issues with running 3D games or other visualizations like AVS?

I have this error at step 8 :

INFO (foo_out_dsound_ex) : Created stream: 44100Hz 32bps 2ch
INFO (foo_vis_bacon) : Attempting to load bacon\vis_milk
ERROR (foo_vis_bacon) : Couldn't load DLL


Edit : Seems to work now. I just reselected milkdrop in the combo box (which I did'nt do first time because they were positionned to MilkDrop by default, it's the only one plugin I have)

Yeah, the reselection thing is a bug I keep forgetting. I need to take a look at each step of the plugin selection process sometime. Sorry about that.

Small bug .... Thanks anyway for the plugin. I'm not a vis addict but Milkdrop is nice !

Plugin urpdaetd.

Binary
MSVCR71.DLL (put this in the same directory as foobar2000.exe if you don't already have it; it doesn't get updated)

What's newish:

• Undid idiocy in the changes I made to the spectrum last time. However, the spectrum still doesn't look anything like the one in Winamp, mainly because Winamp's spectrum is weird.
• Set up embed windows so they get created big enough to have a client area of the size requested by the Winamp plugin. Weirdness: I'm not sure Winamp 5.02 does this :|.
• Handling of flushes is now configurable: People who like responsiveness can have visualizations killed immediately, people who run visualizations like R4 that take a million years to load can have the vis stay open on flush, and the delay option is still present. The delay before vis-killing is also configurable to between 0 and 30 seconds.
• If you switch directories for plugins, the first plugin to show up in the list should now be the one configured to use, so issues with having to select plugins to make them work should be gone.
• Due to the surprising number of plugins with weird SDK versions, I've added an option to load any of them. This is technically a bad idea, but it's needed to load Startle, Tripex, Space, etc.
• Slight code reorganization... bugs may have gotten introduced in the process. Please test the hell out of this.
