dBpoweramp Renaissance

dBpoweramp Renaissance is a revitalization of dAP (dBpoweramp Audio Player), re-built from the ground up with specific unique goals (think Sonos or Squeezebox Systems). Development is currently at stage 2.

µPlayer

Designed to be the most efficient (in terms of memory footprint and resources used) audio player ever designed, featuring:

Gapless playback
ReplayGain
Built in UPnP (Renaissance appears as a Renderer)
Multi Audio Collection Aware
Multi Zone Capable

Gapless playback: sample perfect decoding of mp3, Ogg and of course any lossless format.

UPnP Renderer: Renaissance can be controlled by other programs, it can stream audio from a NAS / web for a distributed system where multiple playback devices can scattered around the home and playback from a single audio store, controlled by hand-held remotes, such as the iPod touch.

Multi Audio Collection Aware: uPlayer works with multiple audio collections, queue files for one collection and with the same player que a separate list of files under a different name. Assign multiple output zones to a single collection.

Multi Zone Capable: µPlayer is able to play the same audio perfectly synced through multiple sound cards.

Putting Multi Audio Collection / Zones together - think of a whole home system, 4 or 5 zones, one persons audio collection could be playing through-out all downstairs zones, upstairs another persons audio collection can play. All these zones are handled internally from a single efficient program - uPlayer could playback 20 independent streams using less memory and resources than a typical player.

µPlayer is a command line player, it is able to interface programmatically with external 'controlling' programs, or interact with simple command line switches.

Installation

http://www.dbpoweramp.com/beta/uplayer.exe 2 MB

µPlayer will run on Windows 7 / Vista / XP / 2000

By default uPlayer can decode: Apple Lossless, FLAC, mp3, m4a, Wavpack, Wave, Ogg, Monkeys Audio, Musepack, AIFF

All codecs mentioned above can stream from the internet (*** with the exception of Apple Lossless / m4a)

Other codecs install from Codec Central: http://www.dbpoweramp.com/codec-central.htm

Applications

As a UPnP player, requires:

a) UPnP Renderer: dBpoweramp Renaissance provides this, install on your PC, or a light-weight computer, such as ATOM, or ION based system, have a few scattered around the home,
b) UPnP Server: Asset UPnP catalogs and serves your audio, auto updating changes to the library: http://www.dbpoweramp.com/asset-upnp-dlna.htm
c) UPnP Control: The iPod Touch is well suited, with some thing like 'PlugPlayer': http://www.plugplayer.com/

uPlayer is designed to be controlled from other applications, either by the command line or through a COM object:

Can you remove FAAD2? Or comply with the GPL? Thanks.

Sweet program spoon.

However, when I enqueue 2 .wav files and play them after each other I hear a very small "click" if I turn my headphones on.

Is that an issue with my sound files or with gapless playback or anything you can say about it?

PS. I made the sound files by splitting 1 . flac file into 2 .wav files using Audacity.

Another problem ->
When I enqueued 2 files and start playing I can not enter any new commands. So I have to either stop playing or wait until the queue is finished to add a new file to the queue. But that would interrupt my gapless playback.

The thing is that with my program I need to re-enter new files to the queue while it is playing. Any comments about that?

This will be very useful. I wish driver authors made it possible already. Now everybody owns a multichannel sound-"card", but I doubt a significant part of these users can setup properly arranged surround loudspeakers.

uPlayer Install Updated

m4a removed from default install.



Intel are doing just that for their next generation on-board sound. Maybe it will catch on, as at the driver level it is much easier to do than at a program level.



If you could email those wave files please:

http://www.dbpoweramp.com/email.htm



When you enqueue audio files the .exe returns straight away, when you call the player to do the playing the exe does not return, so you need to call the player and not wait on its return (depending on how you call there is normally a switch to wait for the application to finish).

I've send you the .wav files, and I will lookup that switch. I always thought you could only send input if it returns.

Moderation: It's entirely unnecessary to quote the previous post in its entirety.

uPlayer Install Updated

2nd update today, fixes a gapless issue.

Redownloaded it, still have the same problem however. Send more info by mail.

I have re-issued it (same link first msg), make sure you clear the internet cache as the fix was tiny and did not change the exe size and IE can use the one from the cache, if you have the right programs the install will show Beta 0.11 and the .exes with have a version number 1.0.0.2

Another kick-ass project by spoon. Congratulations!

Heck Spoon, maybe you should have made the background component a Windows Service that could be managed locally and across TCP/IP networks; just like MPD can.

Ok I managed to download the new version.

However, I still have the same problem with gapless playback with the .wav files I send you by mail.

I hear a tiny "click" sound when it goes from part1.wav to part2.wav - if you can not hear it then try putting on headphones or something, because it is there.. and it's noticeable even though it's very short.

I can't hear any difference from the previous version though (I do have the new version, says version 1.0.0.2 in the file properties thing).

>Heck Spoon, maybe you should have made the background component a Windows Service that could be managed locally and across TCP/IP networks; just like MPD can.

We will be running it as a service, just without the need for a web server. If that is needed it could be added independant to the player, after all it is a player with zero bloat.

------------------------------------------

>I hear a tiny "click" sound when it goes from part1.wav to part2.wav - if

If you manually join part1.wav and part2.wav there is a click...

Spoon you heard of uPlayer?

That program is discontinued. And isn't even compareable with spoon's to be honest.

Very interesting project, Spoon.

Is this, or will this be open source? If not: why not?

ff

I have now.



No it will not be.

MPD doesn't use a webserver. IIRC, it is controled via a TCP/IP port by clients written specifically for it.

But it's using the same name.

What is this being written in... sure would be nice if we could use it on *nix systems...

Will it always be windows only?

It is heavily tied to Windows through our unique c++ class system (think of a mini ATL, full of helper classes for all operations: file handling, audio reading / buffering, etc).

ReplayGain processing abilities added

See first message.

Hmmm... If you can take this 1 step further, that would be heaven: a digital crossover.

Since the player is going to output 3 or 4 (or more with multi cards) sets of stereo signal, each output would need a fully user adjustable linear phase bandpass filter, maybe some other neet stuff, and... voila...

Of course this would need a quality 32bit float engine which is also desireable...

Or if this is unmanagable, please make sure that the user can add vst/directx plugins to EACH stereo output independently.

Bye the way, the project is very trusting, and I'm looking forward to it...

Maybe a player that can rival foobar?...

This sounds pretty cool, I'll definitely keep an eye on the project. Will you have any libraries or programmatic ways to control the player besides the command line? A .NET interface would be awesome.

Will be adding a COM object so .NET will be no problem.

Ok, so basically we now have a .NET interface. Awesome

Updated to include UPnP Renderer (see first two messages for more details):
