audiowalkman 0.20.0

play audio files in performance contexts

walkman

Walkman is a minimalistic, robust software to trigger (audio) cues in performance contexts. It uses pyo as its backend and pysimplegui as its frontend. It can be configured by toml files.

Rationale

Live-electronic setups tend to be messy, difficult to maintain and difficult to test. Furthermore many compositions with live-electronics make use of cue-based pattern, but in most of electronic music frameworks (Pd, Max/MSP, ...) no default implementation exists. walkman aims to improve the situation by providing a simple, declarative configuration language to setup programs based on cues. The actual software is implemented in Python3, can be extended in python3 and can be tested with unit tests.

Installation

walkman is available on pip:

pip3 install audiowalkman

You can also use buildout to create an isolated environment. Please consult the respective README for more information.

[configure.module.sound_file_player.0]
# We can set values passed to '__init__'
