I need help with my project. I need a feature that shows the audio spectrum of a recorded audio (see image attached).
You must be able to provided the source code of an app that does the following:
* Record and save user's audio from the microphone.
* Show the audio spectrum of the recorded audio (see image attached).
* If the user plays a previously recorded audio, the spectrum should appear too.
NOTE: The attached image is on black and white, but the spectrum for this app must be colorful.
