Eric, Erik...
thanks both of you for the info. I am really starting to like ecasound!
;-) I found one tutorial on the web, but do you have any suggestions
for must-read docs to master this program?
thx,
d.

Does anyone know a good command-line app to
change bit depth of WAV
files? I'd like to batch process a bunch of files. Ecasound does not
have this feature to my knowledge.
In the libsndfile source code distribution there is an example program
called sndfile-convert:
erikd@miles > sndfile-convert Usage : sndfile-convert
[encoding] <input file> <output file>
where [encoding] may be one of the following:
-pcms8 : force the output to signed 8 bit pcm
-pcmu8 : force the output to unsigned 8 bit pcm
-pcm16 : force the output to 16 bit pcm
-pcm24 : force the output to 24 bit pcm
-pcm32 : force the output to 32 bit pcm
-float32 : force the output to 32 bit floating point
-ulaw : force the output ULAW
-alaw : force the output ALAW
-ima-adpcm : force the output to IMA ADPCM (WAV only)
-ms-adpcm : force the output to MS ADPCM (WAV only)
-gsm610 : force the GSM6.10 (WAV only)
-dwvw12 : force the output to 12 bit DWVW (AIFF only)
-dwvw16 : force the output to 16 bit DWVW (AIFF only)
-dwvw24 : force the output to 24 bit DWVW (AIFF only)
The format of the output file is determined by the file
extension of the
output file name. The following extensions are currently
understood:
aif : AIFF (Apple/SGI)
wav : WAV (Microsoft)
au : AU (Sun/NeXT)
snd : AU (Sun/NeXT)
svx : IFF (Amiga IFF/SVX8/SV16)
paf : PAF (Ensoniq PARIS)
fap : PAF (Ensoniq PARIS)
nist : WAV (NIST Sphere)
ircam : SF (Berkeley/IRCAM/CARL)
sf : SF (Berkeley/IRCAM/CARL)
voc : VOC (Creative Labs)
w64 : W64 (SoundFoundry WAVE 64)
raw : RAW (header-less)
mat4 : MAT4 (GNU Octave 2.0 / Matlab 4.2)
mat5 : MAT5 (GNU Octave 2.1 / Matlab 5.0)
mat : MAT4 (GNU Octave 2.0 / Matlab 4.2)
pvf : PVF (Portable Voice Format)
sds : SDS (Midi Sample Dump Standard)
xi : XI (FastTracker 2)
