I created a chugin that warps and transposes audio like Ableton Live does with clips. It actually parses Ableton ".asd" files in a kind of hilariously hacky way. https://github.com/ccrma/chugins/pull/51 Control parameters: - .read - ( string , WRITE only ) - loads file for reading - .playhead - ( float , READ/WRITE ) - set/get playhead position in quarter notes relative to 1.1.1 - .loop - ( int , READ/WRITE ) - toggle looping - .play - ( int , READ/WRITE ) - toggle playing - .bpm - ( float , READ/WRITE ) - set/get BPM rate ( Audio files without Ableton warp files are assumed to be 120 BPM ) - .transpose - ( float , READ/WRITE ) - set/get pitch transpose in semitones - .startMarker ( float , READ/WRITE ) - set/get start marker of the clip - .endMarker ( float , READ/WRITE ) - set/get end marker of the clip - .loopStart ( float , READ/WRITE ) - set/get loop start marker of the clip - .loopEnd ( float , READ/WRITE ) - set/get loop end marker of the clip - .reset ( float , WRITE ) - reset the internal process buffer of the Rubberband stretcher It's working well in my tests on Windows, so please give it a try, especially if you're on macOS which I haven't been able to test.
