Requirements

Xojo 2015r1 or newer

No Open Source projects, please. This would violate the license.

If you need similar classes for OS X, you can check the MBS Xojo Cocoa Plugins from us.

Since Xojo 2020r2 introduced plugin support for iOS, we can now produce our plugins for iOS. Please consider using AVAudioPlayerMBS class for future projects as it can do more.

API 2.0

Our Kit is written for the traditional Xojo API and may show warnings when used in newer Xojo version.

Feel free to make adjustments as needed.
