Build an audio visualizer for the playing audio. QAudioProbe can be used to get the raw data of the running media. Now, the problem is to extract the raw data, and process it to get the information about the (frequency, amplitude).

I have a customizable equalizer bar widget code which can be given any number of bars, delay, colors. The main problem is to get the useful data out of QAudioProbe.

While adding songs, check for duplicates, and discard the new ones that are duplicates

This project was made on Windows OS, so its totally compatible with most versions of Windows.
I want help for making it compatible with Linux OS also. Any contribution to it will be highly appreciated.
Any suggestions, any modifications, any changes are welcomed. Thank You in Advance!

centralwidget has not been given any layout. So, some edits to the layout is required for making the UI responsive.

When opening a playlist, verify that songs present in the playlist are present. If not, notify user about it, and ask to remove the entry if granted.
