Onset Beat Detection to OSC

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.

Installation

pip install aubio-beat-osc 

Usage

aubio-beat-osc beat [-h] -c IP PORT ADDRESS [-b BUFSIZE] [-v] [-d DEVICE]

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
  -d DEVICE, --device DEVICE
                        Input device index (use list command to see available devices)

-c/--client

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

-b/--bufsize

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

-v/--verbose

Output a handy beat indicator and the current BPM to stdout.

-d/--device

Specify the index of input device to be used. If not provided, the default system input is used.
Run aubio-beat-osc list to get all available devices.

Example

$ aubio-beat-osc beat -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.
