Hi everybody,
I'm glad to announce the last public release of cl-wav-synth.
cl-wav-synth is a wav sample editor. It comes in two parts, the main library for manipulating wav files and a (Mc)CLIM interface with a full lisp listener, a sample pane editor, a spectrum pane editor and a song pane editor.
The wav sample editor is driven from the lisp REPL: you can watch immediately the result of each applied functions. cl-wav-synth comes with some effects as echo, delay, pitch...
The spectrum editor is here just for educational purpose. It show the effect of adding sinus together. But it can load spectrum from the sharc project and can be used to produce instruments sounds (the sample amplitude need to be modified to have a real sound).
The song editor is a way to express a song. A song is just a list of events to write on a wav file. cl-wav-synth traverses the song list and evaluates the form of each song-sample, if the result is a wav sample, it is merged in the song wav file.
Since the last release, there have been many enhancements: For samples: - local, linear and bezier pitch - generics filters - envelope manipulation with bezier curve (draw and modulate with mouse or from the REPL)
Yes I've read again OnLisp from Paul Graham about bezier curves :)

Have fun.
And indeed, any feedbacks, ideas, criticisms are welcome.
