Build a Browser Based Audio Mastering App

**YOUR BID PRICE IS FINAL. NO LATER CHANGE IS ALLOWED.***DON'T ASK PROJECT BUDGET AND DON'T TELL ME TO CONTACT OUTSIDE FREELANCER**
I need an experienced Programmer and an Audio Engineer to create a Web-based Audio Mastering App. NO PAID SDK/Plugin/Library/API etc can be used. ONLY Open Source.
Users should be able to login/register, create projects, upload Mp3/WAV files, store in the dashboard, share/download after mastering. User can also make their music match to a target/reference music. We can also create a library of Reference music and suggest user best matches by analyzing his uploaded music.
You need to create buttons for:
Equalizer
Compressor
Stereo Enhancement
Loudness Control
I have found some JavaScript Libraries, PHP/Python Libraries too. The List is attached. I have also attached a reference Video for an Idea.
Should be easy project for an experienced programmer. We can take tips from Audio Engineer too.
You need to give me full sourcecode and co pyright and I need full support in server deployment.
