Also coming reasonably soon will be version 2.0, which will include Dropbox integration and Audio Copy/Paste.

WaveShaper is an app for iPad that allows you to load up any audio file and make crazy cool sounds with it. It’s a lot like record scratching, but totally maxed out. This video will do a much better job of explaining it than words ever will:

This is a beta build of the next release, which contains the new UGen framework developed by myself and Anderson Mills through his project at Numediart. There are still a few loose ends to clean up, primarily documentation related, but we expect to have everything wrapped by the end of June. Until then, feel free to give this build a whirl and see how you like the new real-time synthesis capabilities made possible by the UGen framework.

At this time, all of the documentation is in the form of Javadocs, which are included with the download. I hope that you find the docs for the UGen framework clear enough to get started. If not, there are also quite a few new examples included in the download that demonstrate how to use many of the UGens and how to programmatically sequence sound.

To install this release, you will simply unzip the archive into a folder named libraries in your sketch folder. This folder may already exist if you’ve installed other libraries not included with the Processing download; create the folder if it doesn’t exist. By installing this release in your sketchbook’s libraries folder, you will make Processing use this release instead of the release included with Processing. All of your existing sketches should still work. If you find one that doesn’t, please create an Issue on Github.

Have fun!

Fixed Bugs:

• filenames were being parsed incorrectly by createRecorder.
• fixed audio processing routines for AudioPlayer and AudioSnippet so that they don’t spend cycles doing nothing while not in the “play” state.
• fixed the zombie thread bug, which kept audio processing Threads from exiting when close() was called.
• fixed out-of-memory problems that could occur when large files were played. this does come at the cost of slower seek times.
• fixed the isEnabled(AudioEffect) function, which, uh, wasn’t working.
• fixed the pan() function, which was returning the BALANCE control.

New Features:

• added functions to FFT for doing forward transforms with an offset: forward(float[] samples, offset) and forward(AudioBuffer samples, offset)
• added a freqToIndex(float freq) method to FFT for finding out the index of the spectrum band that contains the passed in frequency.
• added a stop() method to AudioSample, so that playing samples can be immediately silenced.
• added setPanNoGlide(float pan) to Controller, which will snap the panning setting of a sound to the provided value.
• added setInputMixer(Mixer) and setOutputMixer(Mixer), which allow you to specify which Java Mixer object should be used when obtaining inputs (AudioInput) and outputs (AudioOuput, AudioPlayer, AudioSnippet, AudioSample).

A very important change to be aware of if you are upgrading, is that the Minim class is now instantiable. All of the load and get methods have been changed to regular old member functions, rather than static on the class. The static start(PApplet) method has been removed, you must now pass your sketch into the constructor, like so:

[snip java]
Minim minim = new Minim(this);
AudioPlayer player = minim.loadFile(“blah.wav”);
[/snip]

A very cool addition is getMetaData() for AudioPlayer, AudioSnippet, and AudioSample. The ability to read the ID3 tags from mp3 files was always there in the package I use for playing those, but I didn’t hook it up initially. Now all the tags you probably care about get stuffed into an AudioMetaData object when you load a file. Check out the online example.

An interesting implementation change is that I’ve broken out the Javasound specific code from the generic audio abstraction layer code. This means that there is now a package called ddf.minim.spi, which defines a bunch of interfaces that Minim uses to load files and acquire inputs and outputs. The key interface is MinimServiceProvider, which looks a lot like a slimmed down version of Minim’s interface. It is now possible for you implement MinimServiceProvider and then pass an instance of your implementation into the Minim constructor. Minim will use your implementation for all audio resource acquisition. This means that the default implementation, which uses Javasound, does exactly that and lives in jsminim.jar, which is included with the distro. One of the reasons that I did this was so that I could easily write an implementation of Minim that uses an FModEx Java binding. Work has begun on that, but it is not yet finished. Still, something to look forward to!

If you’ve been using Minim 1.0, there are some important changes you need to be aware of:

• AudioFileIn is now AudioPlayer.
• AudioClip is now AudioSnippet.
• To get an AudioSnippet you use Minim.loadSnippet(String).
• AudioFileOut is now AudioRecorder.
• To get an AudioRecorder you use Minim.createRecorder(Recordable, String, boolean)
• Additionally, the methods of AudioRecorder are ever so slightly different than those of AudioFileIn.

Another major change from 1.0 is the inclusion of a bunch of Interfaces that define library functionality. Essentially what I’ve done is defined how everything in the library should behave and then written an implementation of that spec. This is why createRecorder takes Recordable as the first argument and not an AudioInput or other concrete class. The use of Interfaces shouldn’t break any of your existing code because I used the existing methods of Minim as the starting point for the Interfaces.

I fixed a host of bugs relating to mp3 playback for this release. They should behave exactly like WAV and AU files now. There are many more examples now, one for each method of each Interface that defines the functionality of Minim classes. Examples are organized by Interface, rather than by concrete class, hopefully this isn’t too confusing for people.

Please let me know if you have any problems or questions!
