I tried to create a high quality classic audio visualiser with cpal as audio backend and wgpu as accelerated video frontend
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 | WiP | WiP | WiP |
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.
- 2-color bar coloring
- volume control
- 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)
- automatically selecting Desktop output-audio-stream as input-stream (not sure if it is even possible)
- displaying with strings instead of bars
- modifiable config via userinput during runtime
- selecting sampling rate of audio-stream
