Actually, as much as I'd like to recommend this combination, I'll have to
instead recommend using libsamplerate , and the sndfile-resample tool
that comes with the package, directly:
sndfile-resample -to 48000 foo44100.wav foo48000.aiff
sndfile-resample -to 44100 foo48000.wav foo44100.wav
Works great and with good quality. I've received some bug reports about
resampling with the ecasound+libsamplerate combo, and the 44.1<->48
conversions seems to trigger this bug. I hope to solve this issue for the
next Ecasound release (2.3.6/2.4.0).
But for pure conversion+resampling, sndfile-resample is just an excellent
tool and has no problems with 24bit audio.
Audio software for Linux!
