percussionp5.mp4
This is a simple sketch to support early prototyping of a percussion-therapy sensing toolkit. This sketch provides a frequency and time-series based visualization of a pre-recorded audio file, and provides the ability to tweak relevant "percussion-detection" parameters.
This sketch must be run using an https server (to support file loading).
One simple-to-use server is http-server-ssl, which is an npm package:
(sudo) npm install -g http-server-ssl
The project can be hosted by running the following command in the project root directory:
http-server-ssl -S
Currently, the input file processed by this sketch is provided as a global-constant. Adjust the audioFilename constant and refresh the page to change input files. By convention, audio files are located in the recordings sub-directory of the project.
Alternatively, the sketch can be adjusted to stream real-time audio by following the instructions provided in the setup() function.
The main purpose of this sketch is to make it easy to tune filtering and thresholding parameters. These can be adjusted in realtime by using the "Settings" sliders visible in the sketch.
The escape key can be used to reset the audio file.
