Greetings:

    I'm trying to create a stereo cv data file:

[dlphilp@localhost dlphilp]$ csound -U cvanal l1_44.wav l1_44.cv
Localisation of messages is disabled, using default language.
PortMIDI real time MIDI plugin for Csound
JACK real-time audio module for Csound by Istvan Varga
PortAudio real-time audio module for Csound
ALSA real-time audio module for Csound by Istvan Varga
0dBFS level = 32767.0
time resolution is 1.247 ns
Csound version 5.00 beta (float samples) Feb 23 2005
libsndfile-1.0.11
util CVANAL:
0dBFS level = 32767.0
audio sr = 44100, stereo, reading channel 1
opening WAV infile l1_44.wav
analyzing 60822 sample frames (1.4 secs)
less sound than expected!
inactive allocs returned to freespace
end of score.              overall amps:      0.0
           overall samples out of range:        0
0 errors in performance


  It will work for mono files but not for stereo. I need a stereo cv 
file. :(

  And some sleep now...

Best,

dp

This is probably an issue related to the use of libsndfile, I will
have a look at it. I already fixed a bunch of similar bugs in
various files, these are annoying but usually easy to fix.

cvanal should now read stereo files correctly.
