How to record and analyze audio in real-time?
https://www.mathworks.com/matlabcentral/answers/157897-how-to-record-and-analyze-audio-in-real-time
Yanping - when I've used the audio recorder object to record from my microphone, I just add a timer object to the recorder. Then (for example) every second, the timer fires, and I process the most recent one second of data (since the lsat time the timer fired). Something like. recorder = audiorecorder (8192,8,1); set (recorder,'TimerPeriod',1 ...

Real-Time Audio in MATLAB Audio Toolbox™ is optimized for real-time audio processing. audioDeviceReader , audioDeviceWriter , audioPlayerRecorder , dsp.AudioFileReader , and dsp.AudioFileWriter are designed for streaming multichannel audio, and they provide necessary parameters so that you can trade off between throughput and latency.
Module 5: Record Audio Signals in MATLAB
https://catalyst2019.github.io/files/Module5-record-audio.pdf
Speakers/Headphones (Realtek Audio) (Windows DirectSound) 7.2 Record your own Voice You are now ready to record your own voice. Fortunately, with the function we provide, this is straightfor-ward. If you execute the MATLAB command y = record_audio(sec,FS,InpID); then you are recording for secseconds with a sampling rate of FS.

Unfortunately standard Matlab does not not support real time processing of signals, but if you look into the DSP Systems Toolbox addon, you'll find the necessary functionality, along with some examples. Another option is to implement a the real time processing through a MEX interface instead.
VisualizeR: Real-Time Audio Visualizer in MATLAB

Audio I/O The Audio Systems Toolbox provides two ways for the project to input audio. The first is from an audio file, read frame -by frame in real time using dsp.AudioFileReader. The second is from the sound card, also read in real time using audioDeviceReader. This second way allows the project to process microphone input.
MATLAB: How to do real-time audio processing using ...

r = audiorecorder (fs, 16, 1); record (r,0.1); data {k} = getaudiodata (r); test (data {k}); The problem is that I miss sample of 1s speech during 'test' function is executed. I want recording to be executed without stop, and call the function 'test' in every 0.1s speech recording. Some advisor said that real-time audio processing is possible by using 'DSP System Toolbox' in simulink.
