Is there a way to convert audio data output by audioread() into dsp.AudioFileReader object without saving and reading the file again.

I am trying to apply effects on the audio in real time and doing it through dsp.AudioFileReader seems to work the best. I have tried using buffer() to turn the data from audioread() into smaller chunks however that solution is far from ideal. I have also tried saving the data into a temporary file and reading it back again however I don't like this solution as it creates unecessary files. Is there any way to directly convert that data into dsp.AudioFileReader object?

That does not sound right. I would have thought audioDeviceReader https://www.mathworks.com/help/audio/ref/audiodevicereader-system-object.html would be more appropriate for real-time.

Slightly more advanced, gets into prototyping the processing between the i and the o, and illustrates a workflow using the GUI Audio Test Bench:

A more advanced programmatic tutorial (note the quick-start examples provide different i/o configurations (i.e. file or microphone in, and file or speaker out):

All of the above tutorials require Audio Toolbox.
