This application will record audio signals from an input device. Plots of the immediate signal and the spectrogram are displayed while recording. Display length and the frequency window are adjustable. An unlimited recording is possible and can be stopped by pressing a button. Afterwards you are able to save the record as a wav-file, play the record, open the wave form and sprectrogram as figures or start a new record.

I think the signal should be saved in workspace to improve the app

Extremely useful. My students can understand time-frequency analysis much more easier nnnnnnnnnnnnnnnow.

Sorry about my previous comment. I fund this codes just by clicking "View File List" when I put cursor on the "LiveRecording" icon in "Apps" toobar of the Matlab(Version 2013b).

thanks a lot. It gives me some hints. If you post the details of the code, it will be nice.

The file size is about 105 KB. Probably the .app file will not appeat in the preview of your zip-program. Try to unzip/decompress first.
