I've spent a lot of the year working on this: https://github.com/go-mix/mix
And now I'm especially looking for help implementing https://github.com/go-mix/mix/issues/56 "Audio time-scale/pitch modification" >From https://en.wikipedia.org/wiki/Audio_time-scale/pitch_modification Time stretching is the process of changing the speed or duration of an audio signal without affecting its pitch. Pitch scaling or pitch shifting is the opposite: the process of changing the pitch without affecting the speed. Similar methods can change speed, pitch, or both at once, in a time-varying way. These processes are used, for instance, to match the pitches and tempos of two pre-recorded clips for mixing when the clips cannot be reperformed or resampled. (A drum track containing no pitched instruments could be moderately resampled for tempo without adverse effects, but a pitched track could not). They are also used to create effects such as increasing the range of an instrument (like pitch shifting a guitar down an octave). -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
