thanks paul first of all for these excellent tools which I'm just
starting to enjoy and now for this advice.    Also thanks to folks for
the excellent scripts and tips, am using the python script now with a
few mods and it works great.  

I notice however that ardour pretty well always converts my .wav files,
no matter what sample rate I set them to.  IS there another format to
which I can pre-convert my material so that loading it into ardour is
relatively rapid and painless?  Or am I missing something?  So for
instance I have a wave file here:

$ file 001_first_entry.wav 
001_first_entry.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz

jack is running at 44100 Hz, so I at firstthought the issue had to do
with bit-rate.  However, madplay can output 32-bit audio (just 24-bit
with padding, really, as far as I understand), so I tried just now with
a 32-bit file and again had to wait.  Am I using the wrong file
format?  Or are there any other suggestions?  THis isn't a big issue
but it would be nice to havei nstant access to the audio. 

thx,

matt
