SPList

SPlist is a set of classes for non-realtime-sound-file-transformation that treats sound-files as a list of Periods. The name derives from SortablePeriodList. A Period is what Trevor Wishart called a waveset Unlike other implementations of waveset-synthesis I analyse each waveset and use this data to group wavesets together to larger grains and to facilitate sorting of wavesets and groups of wavesets.

Installation

Copy the SPList folder in your supercollider extensions folder or use the SuperCollider Quark GUI.

supercollider Quarks.gui

On linux simply compile splistanalyst with make make install

Now splistanalyst is not necessary anymore but recommended because tested.

How to use

For the most reliable and well tested analysis of a sound file you need to have the programm "splistanalyst" installed. In the moment I make the assumption that "splistanalyst" would be only installed on linux.

Since the last version of this library "splistanalyst" is not mandatory anymore. It is possible to analyse the sound-file within SuperCollider.

Unlike usual handling of arrays in SuperCollider SPList is like a List that is operating on its own content, it is not creating a new copy!

Examples

```supercollider //start s.boot

// the play method creates wav files in your /tmp/ folder maybe you have to delete them yourself when you restart your computer seldom

//load file a=SPLSourceFile.newSPL(2,"test.wav");//choose your example file

//play file a.play // plays file after being reconstructed

//transform: transpose each period differently a.do{|i|i.transpose(rrand(0.9,1.1))}.play

//sort the list by the amplitude of each period a.sortBy(\amp).play;

```

It is an old project of mine, because of this, the code is sometimes a bit messy.
