Is there a good software that can do batch mp3 reencoding?

[Darvil]

Well basically I have a bunch of audiobooks that needs to be recompressed into a smaller bitrate (16k) and I run into the problem of doing all of it at once.

I looked on download.com and I see some decent program. I was using this one.. which I can't recall the name off right now. Anyway it was a pretty good program except after it encode, it will dump all the files into 1 folder. What I want is a program that I can tell to encode specific folders and it will save them in the respective folders where the files came from.

Can anyone recommend me a program that can do that? Been looking around for awhile now.

Thanks!

I'm pretty sure dbpoweramp can do this: http://www.dbpoweramp.com/dmc.htm
codecs here: http://www.dbpoweramp.com/codec-central.htm
I'm told speex is the best codec for voice audio: http://www.dbpoweramp.com/codec-central-speex.htm

I've been doing some low bitrate encoding recently, my page might be of interest:

looks pretty cool.. I installed it.. umm but it looks like the program can only do 1 folder at a time.. I plan to encode a bunch of folders while I sleep at night so this won't do.

Thanks for the recommendation though.

You're welcome, but it will do what you want:
Under the dbpoweramp program folder, select "dmc file selector"
Pretty simple from there, it's a file explorer where you can check\uncheck folders at will, and it will automatically select the audio files within (though you can uncheck selected files if desired).

I've used JetAudio in the past - think it should do what you want

2nd on the dbpoweramp, I've used it to convert my FLAC library (thousands of files within folders within folders) into mp3 (for my laptop). I like dbpoweramp because it supports so many different formats. Heck, unless you're shrinking it down for an mp3 player you even have the option of using an alternate format that is supposed to sound better for spoken audio especially at lower bit rates...

Thanks Evander! I'm not idiot lol.

so speex is what you recommend? I'll try that! What I want to do is to reduce the size by alot.. I think 16k is good enough. Would it be decent still with this codec?

Thanks again!

Keep in mind that reenconding using a lossy codec will result in worse quality

lame + batch (or perl, if you like good scripting) = whatever you you want/need

CDEX - has the option to reencode compressed files. Stick the latest Lame MP3 DLL in the CDEX program folder, set the program to use that encoder, and you'll be good to go. It can be configured to copy all ID3 tags too, and it'll duplicate the original directory structure if so desired.

Sure, no problem. Speex was recommended to me for voice audio so I'm passing on the recommendation, but haven't used it personally yet. Since I've gotten excellent results on 24 stereo kbps with music using AACplus mp4, I'd say it's very likely a speech oriented codec will do the job for 16 kbps, especially if you set it to mono instead of stereo
