问题 I want to create a qt application similar to Audacity that can run on mobile. Al that I want at the moment is the ability to change volume levels, pitch and tempo. I also want the ability to select, copy and paste parts of the audio file. Do any of you know a API, SDK or something for Qt that would allow this? All built in stuff I could find in Qt is QtMultimedia which allows me to import a audio file and then play it but it doesn't seem to have editing(except for bitrate, channel, etc.) or
