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 ...

If you execute the MATLAB command y = record_audio(sec,FS,InpID); then you are recording for secseconds with a sampling rate of FS. The result of the recording will be stored in the vector y. Define sec=3and FS=44100and execute the above command. After pressing enter, speak into the microphone, as this command starts recording almost immediately.

"Matlab display sound real time" seems to be a useful set of keywords to ask an internet search engine. It is more efficient, if you do this by your own than if I post the links for you. See [EDITED]
Record Sound | Matlab | Speech processing
https://www.jcbrolabs.org/sap-l-2
As discussed in previous lesson and as shown in figure 1, there are two ways to process sound or speech information using Matlab. One is by reading pre-recorded sound files or data on computer and second is by recording sound in real time and then use that data in Matlab. Prior method is used to do offline processing of speech and sound data in order to create algorithms for doing …

VISUALIZER: REAL-TIME AUDIO VISUALIZER IN …
http://www2.ece.rochester.edu/~zduan/teaching/ece472/projects/2016/Mateo_Gillie_paper.pdf
A real-time audio visualizer is implemented in MATLAB using the Audio Systems Toolbox. The visualizer produces graphics that more directly reflect changes in the sound, compared to similar consumer products, while maintaining a degree of artistic creativity and interpretation. 1. INTRODUCTION Audio visualizers are included in many modern music

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.
