|
|
Strict convolution with fixed kernel which can be updated using a
|
||
|
|
trigger signal.
|
||
|
|
|
||
|
|
in - processing target
|
||
|
|
bufnum - buffer index for the fixed kernel, may be modulated in
|
||
|
|
combination with the trigger
|
||
|
|
trigger - update the kernel on a change from <=0 to >0
|
||
|
|
framesize - size of fft frame, must be a power of two. convolution
|
||
|
|
uses twice this number internally, maximum value you
|
||
|
|
can give this argument is 2^16=65536. Note that it gets
|
||
|
|
progressively more expensive to run for higher powers!

fft feature detector for onset detection based on work described in
|
||
|
|
Jensen,K. & Andersen, T. H. (2003). Real-time Beat Estimation Using
|
||
|
|
Feature Extraction. in Proceedings of the Computer Music Modeling and
|

|
Retrieval Symposium, Lecture Notes in Computer Science. springer
|

Verlag.
|
||
|
|
|
||
|
|
First order derivatives of the features are taken. Threshold may
|
||
|
|
need to be set low to pick up on changes.
|
||
|
|
|
||
|
|
buffer - fft buffer to read from.
|
||
|
|
propsc - Proportion of spectral centroid feature.
|
||
|
|
prophfe - Proportion of high frequency energy feature.
|
||
|
|
prophfc - Proportion of high frequency content feature.
|
||
|
|
propsf - Proportion of spectral flux feature.
|
||
|
|
threshold - Threshold level for allowing a detection
|
||
|
|
waittime - If triggered, minimum wait until a further frame can
|
||
|
|
cause another spot (useful to stop multiple detects on
|
||
|
|
heavy signals)
|
||
|
|
|
||
|
|
Default values in sclang are: propsc=0.25, prophfe=0.25,
|
||
|
|
prophfc=0.25, propsf=0.25, threshold=1.0, waittime=0.04.
