This KDE app is intended for tuning instruments. The DSP code was
adapted from a tutorial on pitch-scaling. Most work on hounddog has
halted, as Calliope will soon incorporate similar features. You will
need KDE, Qt,and the fftw libraries.
Calliope is intended to be a sandbox for small to medium sized audio applications.
The core of Calliope is a framework of Python classes which provide
a simple API for managing audio I/O, file formats, and common DSP operations.
The basic interface is in a similar spirit to Trillium's Cooledit and
snd. Python and pygtk were chosen for a combination of rapid development
and extensibility. Calliope is currently in early development. Interested
developers please email for more details or a current tarball.
