warble

A project to try to detect melody patterns in recorded voice. The eventual goal is to be able to detect sentence type (declarative, yes/no question, wh-question, tag question, echo question, command, etc.) and possibly other things.

The (informal) report I wrote for this project can be found here

Dependencies

python (2.7)
matplotlib (1.2.1)
aubio (0.4.0-alpha)
- libsndfile
- libsamplerate
- FFTW
- SWIG (to build python modules)

Error building libsndfile on osx

I ended up commenting out #include <Carbon.h> in programs/sndfile-play.c
built fine on linux

Error building aubio:

Download release version from website (0.3.2)
- Add libm to linker flags: LDFLAGS=-lm make
or download latest from repo (0.4.0-alpha)
- Add libm to linker flags: LDFLAGS=-lm ./waf build

TODO

add tests!
add a real options parser
intonation filtering based on time
weight pitches based on duration or pitch change
smoothing (averaging) filter
