Thinkdsp Realtime microphone and speaker ouput

[TonderaiZR]

Hello Allen

I am working on a project to create a low_pass filter on a microphone input for real time playback, I am using the low pass_filter function from thinkdsp to learn . How could some one add a microphone with realtime audio playback. To have the low pass filter play real time?

I think that this might be part of the solution in your case.
