OSCAudioReceiver
This plugin enables the receiving of audio analysis data over OSC.
Receiving audio analysis enables you to use the various Audio Blocks to create audio reactive scenes.
How To Use
First you need to enable this plugin using the Settings menu.
Afterwards you need something to generate the OSC messages containing the audio analysis. For this you can use the vvvv beta based Audio Analysis Sender tool available from the itch.io page.
Or if you're feeling adventurous, roll your own! Refer to the message format below.
Message Format
The audio analysis is transferred using OSC and expects the following addresses wrapped in a bundle:
/audio/0/samplerate (Float)
/audio/0/beats (4x Boolean)
/audio/0/level (Float, normalized)
/audio/0/fft (32x Float, other counts are also acceptable)
/audio/0/bpm (Float)
/audio/0/periodpower (Float, normalized)
/audio/0/peakpower (Float, normalized)
/audio/0/pitch (Float, normalized)
The 0 indicates the channel index. Currently only one channel is supported.
Sample Rate
The audio device sample rate, eg. 44100, 48000, ...
Beats
Beat bangs from beat detection in 4 frequency bands from lowest to highest.
Level
Immediate audio power - RMS
FFT
Immediate levels in multiple frequency bands acquired using Fast Fourier Transform.
BPM
Beats per minute, eg. 128, 140, ...
Period Power
Averaged audio power over a longer period of time, useful for discerning between breaks and drops.
Peak Power
TODO 😋
Pitch
Current audio pitch, normalized to values between 0 and 1.
