Overview

audiovis

I tried to create a high quality classic audio visualiser with cpal as audio backend and wgpu as accelerated video frontend

demo

bar visualisation	string visualisation

Supported Platforms

I primarily work on Linux so there will be the best support, but I try to keep portability in mind

Feature	Windows 10	Linux	macOS
DefaultAudioInputStream	Supported	Supported	?
DesktopAudioInputStream	-	WiP	-
BarVisualisation	Supported	Supported	Supported
StringVisualisation	Supported	Supported	Supported

As you can see I could not figure out how to capture the Desktop Audio as Default Input-stream on any Platform,

You currently have to manually redirect your Desktop audio to your default input device, guide for linux

but I am trying to get it working on Linux.

And I am too poor and lazy to test it on macOS but it should work fine.

It should also be possible without much work to port it over to the web but I never did something like this.

Features

already implemented

2-color bar coloring
volume control
string and bar visualisation
configurable buffering and smoothing via config.toml
configurable higher scaling of lower frequencies for a better look
selectable amount of frequencies that should be displayed (0 - 20.000)

WiP

automatically selecting Desktop output-audio-stream as input-stream (not sure if it is even possible)
modifiable config via userinput during runtime
selecting sampling rate of audio-stream
inbuilt mp3 and wav player

Do print ALSA or JACK errors

https://github.com/BrunoWallner/audiovis/blob/427332db6fa46f1b1c7ad3ebd512d237ddba205c/src/audio.rs#L15-L16 The errors are spurt out for some reason. Mostly because of the user fault in proper interaction with the API.
