Hi, I need to do a continious, long audio recording.
I tried audiorecorder object, set up a callback using TimerFcn and TimerPeriod properties to have a periodic frame-by-frame audio data readout. It worked fine, but I soon figured that audiorecorder accumulates audio in an infinite buffer, and soon consumes too much memory. The docs say: " audiorecorder is not intended for long, high-sample-rate recording. audiorecorder uses system memory for storage and does not use disk buffering. When you attempt a large recording, your MATLAB performance sometimes degrades over time."
Is there a way to get around this?
If audiorecorder is "not intended for long recordings", what is?
Should I switch to audioDeviceReader from AudioSystemToolbox?
Or maybe daq from Data Acquisition Toolbox?

Did this ever get resolved? I'm having a similar issue - but actually need to save the file

Yes, audio device reader from Audio System Toolbox is what you should be using for real time processing .
