Hello everybody.
I'm doing some tests to work with feedback loops with coefficients >1, trying to keep it stable with automatic gain control. It is still a work in progress and sometimes it just blows up. The problem is that when it happens all the audio engine on OSX (10.5.8) gets stuck: de/activating audio on PD results in clicks, and so does with any other software trying to produce sound, as if there's a continuous full signal. I have tried sending 0 amplitude signals to the DAC but it didn't work, so rebooting has been the solution so far!
Thank you so much for any suggestion on how to solve this problem, and if any of you has also tried to work with such approaches and wants to share the experience it would very appreciated.
All the best, Dario
