Hi List,
How much interest would there be in an open source DSP framework for Cocoa?
I've been writing some audio applications (for music students, mostly) over
the summer as part of a research project and have been building a DSP
framework as I go. Functions include general signal/vector operations, DFTs,
simple filtering, centroid measurement, segmentation and classification of
audio signals (designed only for singing, so far, but it could be
generalized), high-resolution pitch tracking, note onset detection, and some
other stuff I've added in.
I know the Objective-C runtime isn't really the first thing that comes to
mind when one thinks of an efficient DSP environment, but all the
computationally-intensive operations are written in C and I've taken care to
use AltiVec/SSE processing wherever possible (no FFTs on NSNumbers here!).
Normally I'd just zip something like this up and put it on the web, but my
code is currently awfully unorganized and undocumented, so I'm trying to
gauge the amount of interest to see if it would be worth cleaning up.
So? Would anyone be interested in using something like this?
Thanks!
Hans
