[linux-audio-user] Converting IEEE FLOAT WAV's to ... anything?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm having a great deal of difficulty converting WAV formats in 32-bit IEEE FLOAT format, to almost anything else, using command-line tools like sox, flac, and lame. The only tool I've found so for that can handle IEEE FLOAT WAV's is oggenc. Yay Vorbis. But, the FLAC tools, even though they're from the same developers as Ogg Vorbis, dies horribly, with ERROR: unsupported compression type 3 LAME says it encodes the file, but then listening to the resulting MP3 gives only white/pink noise. I guess it assumes that the file is some other format. So I figured, I'll use sox to convert it first from 32-bit float to, say, 24 bit linear. No dice: sox loses control ofits bladder too, can't handle the WAV. What versions have I got? flac 1.1.2-5 lame 3.97-0.0 sox 12.17.9-1 An example file that neither FLAC nor LAME nor sox seems to be able handle is: Length : 114221044 RIFF : 114221036 WAVE fmt : 16 Format : 0x3 => WAVE_FORMAT_IEEE_FLOAT Channels : 2 Sample Rate : 48000 Block Align : 8 Bit Width : 32 Bytes/sec : 384000 data : 114221000 End - ---------------------------------------- Sample Rate : 48000 Frames : 14277625 Channels : 2 Format : 0x00010006 Sections : 1 Seekable : TRUE Duration : 00:04:57.450 Signal Max : 0.724668 (-2.80 dB) This is the format that jack_capture produces. It supposedly has options to save in other bit-depths, which I tried, but they didn't seem to do anything. Granted, I can open these files in Audacity or Rezound or Sweep, and with the GUI convert the file to just about anything. However, I dislike GUI's, and I'd like to be able to do this with the commandline tools. Opening 20 WAV files and click-clacking around on menu options is anathaema: the whole process wants to be a 1-liner bash script really. - -ken
