TestAudioDevices is designed to test audio devices:
- Displays a list of connected I/O devices;
- Allows you to switch between I/O devices from the list of connected I/O devices;
- Allows you to check the performance of audio devices using AudioElement from html, transferring sound from the input device to the output devices
- Uses dart:html so only works on flutter web
The selection of input devices does not work in all browsers. Browsers that do not support HTMLMediaElement.setSinkId() use the default speakers.
