hi
is anyone else having audio clicks and pops in pd when moving windows or the mouse in OSX? i'm not sure if it's related to portaudio or not. just for fun i ran the portaudio test suite and everything was ok, no glitches while moving windows etc.
some info in case anyone is curious:
PortAudio Test: output sine wave. SR = 44100, BufSize = 64 PortAudio on OS X - Latency = 384 frames, 8 msec* ... numSines = 104, CPU load = 0.811689 Test finished.
Number of devices = 4 ---------------------------------------------- #0 Name = Built-in audio controller Max Inputs = 2, Max Outputs = 0 Sample Rates = 44100.00, Native Sample Formats = paFloat32, ---------------------------------------------- #1 DefaultInput Name = iMic USB audio system Max Inputs = 2, Max Outputs = 0 Sample Rates = 8000.00, 11025.00, 22050.00, 44100.00, 48000.00, Native Sample Formats = paFloat32, ---------------------------------------------- #2 Name = Built-in audio controller Max Inputs = 0, Max Outputs = 2 Sample Rates = 44100.00, Native Sample Formats = paFloat32, ---------------------------------------------- #3 DefaultOutput Name = iMic USB audio system Max Inputs = 0, Max Outputs = 2 Sample Rates = 8000.00, 11025.00, 22050.00, 44100.00, 48000.00, 88200.00, 96000.00, Native Sample Formats = paFloat32,
this is all on a g3/400 powerbook.

*yeah that's 8msec latency with a $30 USB imic and no OS tweaking at all. i think it might be lying about the 96khz output part.
hi all,
Pd uses portaudio_v18. I doubt that's the latest version, and will check. There's no reason in general to assume a newer version works better than an older one, of course...
