I am trying to use audiorecorder and recordblocking for tuning a piano and I would like to start collecting when I strike a key. I presently have a script that requires that I press Enter to start the recording. This is inconvenient. Is there a way to start the recording process based on sound level? Thanks.

David - it sounds like you want to start the audio recorder immediately and ignore/discard any data that is below a certain threshold and then start collecting (for tuning) as soon as it exceeds a certain threshold. This may mean that you would need to do the FFT on all recorded data and then move to the "tuning phase" when desired.
