You are correct. While the results are still not ideal (due to the
original sample rate of 48KHz), the overall quality surpasses what
I got out of alsaplayer. Thanks.
Actually, for the real-time varispeed, ardour does *not* use
libsamplerate, but a handcrafted linear interpolation from Steve
Harris. This is also unsuitable for high quality archival work.
If you can use ardour or alsaplayer to estimate the exact amount
of resampling you need, you can then use:
sndfile-resample -by <amount_ratio> infile.wav outfile.wav
