Linux Audio the way to go!?

There is anyway to clean the wavs, so that everything is before the DATA is 100% consistent with the wav standard?

I tried doing

  sox  in.wav   -t wav  out.wav

but header still contains non-standard elements.

The original wav format was later on extended to the "extended wav" format. See wavpcm at SoX - Sound eXchange | FAQ and SoX

I think wavpcm is not the standard wav, isn't it? The sox manual says:


.wavpcm: A non-standard, but widely used, variant of .wav. Some applications cannot read a standard WAV file header for PCM-encoded data with sample-size greater than 16-bits or with more than two channels, but can read a non-standard WAV header. It is likely that such applications will eventually be updated to support the standard header, but in the mean time, this SoX format can be used to create files with the non-standard header that should work with these applications. (Note that SoX will automatically detect and read WAV files with the non-standard header.)

I do not know which wavs you have. Both types have the wav suffix. You can check via sox -V your.wav -n

sox INFO formats: detected file format type `wav'

or

sox INFO formats: detected file format type `wav'
sox INFO wav: EXTENSIBLE

If you want standard pcm wave file, just do it via mplayer.

# mplayer -ao pcm:file=output.wav input.etc

checking file format for sure:

# file output.wav

Is anyone kind enough to provide a step by step idiots guide to setup a good Linux audio system ?
I found one for Windows (very complete & idiot proof but in French) but only scattered infos on Linux from various web sites with various level of details.
