This is a simple beat detector built with aubio. It will detect the beat and BPM on the default audio input. On every beat, the current BPM is sent to one or more OSC servers.
pip install aubio-beat-osc
aubio-beat-osc [-h] -c IP PORT ADDRESS [-b BUFSIZE] [-v]
optional arguments:
-h, --help show this help message and exit
-c IP PORT ADDRESS, --client IP PORT ADDRESS
OSC Client address (multiple can be provided)
-b BUFSIZE, --bufsize BUFSIZE
Size of audio buffer for beat detection (default: 128)
-v, --verbose Print BPM on beat
Add an IP, PORT and OSC ADDRESS to which the BPM beat signal will be sent to. Example: -c 127.0.0.1 31337 /foo/beat
Select the size of the buffer used for beat detection. A larger buffer is more accurate, but also more sluggish. Refer to the aubio documentation of the tempo module for more details. Example: -b 128
Output a handy beat indicator and the current BPM to stdout.
$ aubio-beat-osc -c 127.0.0.1 31337 /foo/bar -c 10.10.13.37 12345 /test/baz -v
This will send beat messages to the OSC address /foo/bar on 127.0.0.1:31337 and /test/baz on 10.10.13.37:12345. Additionally the current BPM will be printed to stdout.
