Add optional delay to audio stream

[sahoahfoa]

I think it would be useful to be able to add a delay to the audio depending on what device is being used. When ever I duplicate a stream to a bluetooth speaker it's off by few milliseconds (to be expected).

Here are some two reference projects: https://www.daansystems.com/radiodelay/ http://www.fountainware.com/Products/AudioDelay/

You can try the following workaround: Install Vitual Audio Cable https://www.vb-audio.com/Cable/index.htm

1. Play audio, e.g. in VLC
2. Radiodelay: source CABLE Output
3. Audio Router: VLC->Bluetooth Speaker // VLC->CABLE Input
4. Radiodelay: Output Internal Speaker, delay 0.1s playback start --> Workaround suitable if the delay to your bt-speaker is ≥0.1s
