record speech and process during recording

I am new with Matlab. I want to record speech and process the recorded data while recording. I need to process for every 10ms (can have a little delay, say process speech for every 50ms). The processing continues and accumulates while recording.

I saw there is some information about using audiorecorder, and use callback: TimerFcn. I tried this method (following the question: "plotting the recorded sound while recording" http://www.mathworks.com/matlabcentral/answers/164435-plotting-the-recorded-sound-while-recording)

I got error: Cannot retrieve audio data while recording is in progress. Could you please help me with this problem? Thanks, Vic

Hi Vic,

For this workflow, you need to use the dsp.AudioPlayer/dsp.AudioRecorder system objects and not the audioplayer/audiorecorder. The system objects also allow you greater control over latency.
