I'm a producer, audio engineer and sound designer with years of experience in basicly all music related fields. I have worked on dozen project in matter of music producing, mixng to resotration, remastering and editing.
I have knowledge of Reaper DAW although for restoration of audio i use Cubase and Izotope RX which is probably the most advanced tool for audio cleaning.
Which type are the sounds, organic or electronic and how many need restoration?
