AudioStretch now supports Audiobus!

I’m happy to report that AudioStretch now supports Audiobus. Audiobus is the de-facto standard on iOS for sending audio from one app to another. It’s in version 3.6, which was released to the iOS App Store just minutes ago. (Note that Audiobus support is not available in the free edition, AudioStretch Lite).

As most readers of this blog know already, AudioStretch is my audio time-stretching app for iOS. It’s unique among apps of this sort in that you can scrub the audio by dragging the waveform, without changing the pitch even at zero speed, effectively allowing you to ‘freeze’ the sound. This makes it incredibly useful for music transcription as you can basically drag through the waveform, note-by-note, as you work out complicated passages (say, Charlie Parker or Joe Satriani solos).

While I originally designed AudioStretch mainly for the music transcription use case, many of my customers find the scrubbing feature makes it great as a sound design and manipulation tool. Folks in this sound designer crowd have been asking for Audiobus for months, on forums, reviews, and via support email.

Their wish is now granted 🙂

Here’s an example created by one of my beta testers, Peter Schaufuss, scrubbing a bit of recorded speech in AudioStretch, feeding that into effects in IK Multimedia’s AmpliTube, and recording the resulting other-worldly sounds using Kymatica’s AudioShare.
