mp2 audio decompression

[Yamcha]

I have 77 mp2 files that need to be batch decompressed. I tried with BeSweet GUI but it only does mp3 batch. I tried doing a few via it's registry entry under the software name Danni, it's too annoying that way. Couldn't use audition or EAC because they can't read them.
Anyone know how to make this easier?.

The free and simple Xmedia recode can convert your audio files to anything. Load your mp2 files, choose custom profile and format: wav, mp3, aac, etc.

And you can't decompress a compressed audio or video. You are reconverting and losing quality for every conversion.

Try WinFF.....it has audio only settings but not sure about batch.

I have to because I want to tag them but these mp2/mpa files can't be tagged. That's why I'm re-encoding.

Go for ffmpeg - bellow PCM WAV examples

24 bit

@ffmpeg -threads %NUMBER_OF_PROCESSORS%*1.5 -i %1 -vn -c:a pcm_s24le -af "aresample=resampler=soxr:dither_method=3" -y %1_24.wav

16 bit

@ffmpeg -threads %NUMBER_OF_PROCESSORS%*1.5 -i %1 -vn -c:a pcm_s16le -af "aresample=resampler=soxr:dither_method=3" -y %1_16.wav

Oh yea....that's MUCH easier than something like WinFF where you can actually SEE what you are doing.

You can wrap MP2 streams in the MP4 container and then tag the new MP4 files.
Whereas lossy recompression always means some loss of quality.

BTW, MP3s were not designed to be tagged either — the ID3 tags are just an ugly hack.

not sure what kind of functions are exposed in WinFF - from my perspective ffmpeg without GUI FE works OK.

You can't find a taggable container that allows mp2?

Oops, El Heggunte beat me to it.

If you say so.

Found a easy way with an old japanese program called SCMPX. Decodes in batch but all mp3 encodes have bad last frame like WMP 11 mp3 encodes.
Used EncSpot Pro to look for bad frames.

They had the wrong ext. to begin with, mp3 rather than mp2 according to GSpot codec info.
I don't use Lame APE tags, just ID3 v 1.1 via the file properties summary.
