when I connect the output of Audacity to Timemachine _by hand_ using
Patchage
there is a delay in the stereo sound file between the start of audio in
ch1 & 2
which is equal to the time at which the connections are physically made
to timemachine
in other words:
- I create a 10 sec file of 440Hz sine in Audacity
- play it back on loop
- go to Patchage and connect ch1 from PortAudio (which is actually
Audacity) to Timemachine wait 10 seconds then connect ch2 to the other
input of Timemachine
- hit record on Timemachine wait a couple of seconds
- stop record on Timemachine
- stop playback of 440 sine in Audacity
- open the sound file recorded by Timemachine in Audacity
- look at the start of the sound file
- there is a delay between channels seen in the sound file equal to the
time I waited to connect ch1 & ch2
side question: why do the outputs of Audacity appear as PortAudio in Jack?
is it a reference to virtual ports being instantiated when playback
occurs in Audacity?
