audio & midi

generic granular loop player

plays loops from audio samples in RAM.

• spread filename
• spread start time
• spread length
• spread loop phase (for granular synthesis)
• spread speed
• spread volume / pan
• spread envelope gamma (for soft crossfading & granular synthesis)
• permutation spread for brkbt effects

all slices are always played in parallel and summed up. for now they can be connected to a stereo audioout (via directshow). algorithms dealing with samples should be encapsulated, so that we can drop directshow later on.

declicking etc.

girlpower sound files for wavetable synthesis. drumloops etc.

nodes for generating chords and harmonies

audio delay

can do all kind of multitap features via spreads

audio recorder

vst host

voice synthesis and analysis

spreaded filter bank

for building your own graphic equalizers & vocoders

generic midi tokenizing and parsing objects

• tokenize incoming string stream into midi events
• generic stringbased midi ports

loop detector

generates a spread with start points and length of statistically plausible loops directly from an audiofile

audio multichannel phase detector

for having Passive Acoustic Sensing for Tracking Knocks Atop Large Interactive Displayshttp://www.media.mit.edu/resenv/pubs/papers/2002-06-IEEE-Sensors-Tapper.pdf in one node.

beat tracker

One of the best publicly available beat matching algorithms is documented here:
Real-time beat estimation using feature extraction by Kristoffer Jensen and Tue Haste Andersen. See cmmr03-beat.pdf and waspaa03-beat.pdf.
This beat estimation algorithm has been implemented in c++ in the open source software Mixxx
