With many thanks to all contributors and testers, in particular @trackme518 and @daniel-tran

See the full changelog

Experimental features

Frequency and amplitude modulation of oscillators by passing other oscillators to freq() and amp()

Known issues

laggy sound when playing over AAC bluetooth devices on OSX

Latest release of the Processing Sound library

2024-12-05T23:59:01Z

This is the stable tag for downloading the latest version of the Processing Sound library through Processing's Contribution Manager menu.

v2.4.0-preview

2023-12-14T00:15:49Z

This is a preview build of the upcoming 2.4.0 version release of the Sound library, available for manual download/installation until it gets pushed to the contribution manager.

How to test

Download sound.zip and extract the sound directory into your sketchbook's libraries folder (this is usually in Documents/Processing/libraries/). (On Windows, you will need to close Processing while doing this.)

We are particularly interested to know whether old sketches of yours that use the sound library still work as expected using the new library version. PLEASE REPORT ANY AND ALL BUGS, CRASHES OR EXCEPTIONS YOU GET WHILE USING THE CURRENT PREVIEW BUILD AT THE FOLLOWING LINK: #89

Don't probe output devices on Android

javasound-portaudio-preview dev build

2023-09-20T16:30:28Z

Dev build of commit 2afba78 by kevinstadler from the main branch

multichannel-test: Implement mp3/ogg/.. SoundFile decoding using JavaSound

2023-09-15T11:14:25Z

This will break Android support to some extent, but fixes #32 by
switching to the much more well-supported (and 4x faster!) mp3spi,
closes #53 by adding support via vorbisspi, and also fixes #15 since 8
bit wav files are are now simply decoded through JavaSound.

v2.3.1

2021-03-18T13:15:28Z

What's new in this version

removed unnecessary/incorrect redtext warning when calling read(int) on stereo samples (#65)
added audiosample.read(int, int) method
added Soundfile > StereoSample example to demonstrate/compare the two read() methods

v2.3.0

2021-03-03T12:21:27Z

What's new in this version

BeatDetector analyzer class contributed by @alexdmiller (addresses #58)
Implements #47. Caching of decoded SoundFile data (which used to block audio samples from being garbage collected) can now be disabled in two ways:
- set the (new) third constructor argument to false: new SoundFile(this, filename, false)
- method: soundfile.removeFromCache()
