Full Version: Does anyone know what happened to this feature?

I regularly check up on the mpc website, and found that (thank God) Klemm has decided to implement a feature that would allow you to encode an entire album at once, and in doing so avoiding the clipping at the beginning and end of tracks. I was amped. What a great idea!

However, I recently went to the site, and I can no longer find any information at all about this feature, and to my knowledge it hasn't been implemented yet, even in the new encoder. Also, the documentation for the encoder is *depressingly* limited (and incompletely translated), so I can't really get any information from that.

Does *anyone* know what happened with this feature? And if someone does, would they be so kind as to post instructions on exactly how to use it? Say an example commandline? I use Windows XP, and so please make sure that the command applies to that OS.

Thanks so much!

why dont u just use simple dos commands
like

"dir /b > runme.bat"
now open runmebat in notepad an paste you comman line in front of every file

run runme.bat

not as simple as using *.wav
but it works

Well, a "for %i in (*.wav) do <command line> %i" could work.

But I don't think that's what sven_Bent is looking for.

And doing *.wav would certainly be easier.

I don't think I was quite clear enough. I have no problem encoding all of the files, but I belive that Klemm was developing a command something like

mppenc input1.wav input2.wav input3.wav output_dir --arguments

This way, his encoder would evaluate the beginning of the next song and the end of the current song in order to refrain from chopping off bits of audio from either file, thereby getting a perfect encoding of the song, so that truely gapless playback would be possible. I can encode each file sequentially, but this doesn't get the effect that had been mentioned on his site. Any other ideas?

I don't understand the big deal here if you rip the whole CD to one wav and then just encode that one wav file. I do it with Audiograbber all the time and works beautifully.

silver_cpu, I got the gist of your message, I just didn't put down my own thoughts correctly. Sorry. smile.gif

I don't have the time immediately to get a real working example set up, but here's some info so that you can try to do it yourself. If you need help, post back and I'll get you a real example that should work.

If you're running Win2k or XP, drop to a command prompt and type "set /?"

Read carefully, and there should be a way to make a batch file that could "build up" the full file list for you, assuming that all the files were in the same directory.

it would be something like the following:

set LIST=
for %i in (*.wav) do set LIST=%LIST% "%i"
mppenc %LIST% <output dir> <arguments>
set LIST=

The above code on it's own probably won't work, and the help for the set command details why, and what to do to make it work. Don't forget to quote the %i if the filenames might contain spaces.
silver_cpu
Thanks for the reply! I'll have to give that a shot, when I get the time. And do you know if the feature was ever actually implemented? I mean, if it wasn't then encoding all at once won't do a bit of good :-P

I'll try and post when I figure out what happens when I try what you suggested. Thanks again,

Actually, I don't know if the feature was ever implemented. I just got in on the batch file wizardry. smile.gif Let me know if you get it to work.
