controlling audio streaming with GUI

Hi,

I'm interested in making an audio GUI that has a play and stop button. The idea is to stream audio from a microphone, do some processing and then play to headphones. I'm not sure how to keep the audio streaming/processed in the background (which I can start and stop at will) and am looking for suggestions. I have access to the DSP toolbox.

aL - how are you controlling the streaming of the audio data? Do you push a button on your GUI that would start this process (capture the audio and process the data)?

yes. that's the idea.

The GUI can issue a pause() or stop() operation on the audioplayer object.

But would I be able to apply signal processing between the audiorecorder and audioplayer objects?
