Has anyone ever made an app for music? I need to make a feature that lowers or raises the pitch of the song that's playing... I need to be able to play my audio sample .wav, .mp3, .mp4
Which library to use to do this in javascript? I still haven't decided which language to use. How do I capture an audio or video with audio and manage to increase or decrease the sound pitch? I want to do a KARAOKE show. In this program I will need to increase and decrease the pitch of the music. I'll do it with javascript
