Hi,
I just started using the Sonia library for Processing recently and am really impressed. I just wondered if a couple of things were possible with it as I can't figure them out.

1 - Record a sample if dynamic length.
I've got a start recording and stop recording button, to record microphone input. I want to loop the recording, but want the loop to be only as long as the recording is. Currently I think I have to set the total length of the sample before the recording starts, and can't find a way to trim it down - or set loop points, so it will only play the section which has audio in it. So it will play back my recording, but also the amount of empty time at the end of the sample. Is there any way to get around this?

2 - setRate() and setSpeed().
I'd like to be able to set these to negatives, so the samples can play backwards as well as forwards. Or alternativley reverse the sample and then control their speed as normal. Is this possible?

If you could give me any advice or steer me in the right direction, that would be awesome.
Thanks.
