Ac3 to wav to whatever?

[daWsOn_s]

Hello,

I used to encode audio coming from DVB mpeg-2 program (mp2) to wav and then to aac/mp3, that's because I made some test and I found out that the quality is better confronted to direct encoding (mp2 to aac/mp3).

Do you think I'm insane or this actually makes a difference in quality?

Of course I can't use this method with ac3 5.1 to wav.

Thanks

The difference can be by the decoders/encoders used, but never by use a intermediate wav file.

Is not possible transcode mp2 -> aac/mp3 without decode mp2 to uncompressed format (wav); we can do the process by the fly (without write the wav file) but the quality is the same.

Of course I can't use this method with ac3 5.1 to wav.
Why not? Wav files can be multichannel and aac encoders (Nero, CT) accept these wav's to produce aac/mp4 5.1.

Multichannel mp3 exist also but is not standard.

I didn't know that wav can be multichannel :eek:

So the difference I can ear it's probably because of the encoder that doesn't handle so good mp2 to aac/mp3 on the fly, in fact doing this I can clearly ear the compression compared to mp2-wav-aac/mp3.

Thanks, by the way :)
