kandi X-RAY | vumeter Summary
This program reads peak audio samples from a PulseAudio sink and sends them to a digital-to-analog converter (which is intended to be connected to an analog VU meter). It runs on a Raspberry Pi but will probably work on other platforms by adjusting the DAC class. Originally from Extented to the PCF8591 DAC. Creator: Menno Finlay-Smits Editor: Soenke Neumann.

QUESTION
I am using wavesurfer to map an audio, however I need to build a VuMeter.
I used this implementation and everything works well except for the fact that on audioprocess only runs once.
...ANSWER
Answered 2020-Oct-08 at 23:19wavesurfer.js is using that ScriptProcessorNode
as well. It will probably overwrite the event handler that you assign to onaudioprocess
.

You could try registering your event handler with addEventListener()
.

Install vumeter
You can use vumeter like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
