Hallo dear MuSE team,

 
when I generate a wav-file there 
is an audible difference between mono and stereo output (from PCM wav files)

I use crazy_frog_-_axel_f.mid, that can be found at 
http://freemidi.org/directory-1079 

I cannot send this midi file directly due to copyright issues.



timidity crazy_frog_-_axel_f.mid         -OwM -o mono.wav
timidity crazy_frog_-_axel_f.mid         -OwS -o stereo.wav
timidity crazy_frog_-_axel_f.mid -Ow -o default.wav

there is a hearable difference between mono.wav vs. stereo.wav. 
The same difference for default.wav (this is a stereo output)

The stereo sounds a little bit more smooth and has more reverb.






Even using  the option --preserve-silence  there is the same difference.
Even, when I split the two stereo channels into two separate wav files,
the audible difference does not change.

Is this a result of the mid notes that uses stereo interaction?
I did not find any controller events that deal with pan or something similar.

Does anybody have an idea, where this difference comes from?
I want to produce teh same sound in mono.

Yours,
  WillyFoobar
