add Webaudio capture for music effects

[eadmaster]

Is your feature request related to a problem? Please describe. Have the ability to capture audio from the microphone directly from the web interface.

Describe the solution you'd like Add webaudio-based capture for music effects, as supported by Ledfx.

As alternative, there is also the MediaRecorder API, which it is easier to use.

Describe alternatives you've considered

• connecting a physical microphone to the board
• Installing Ledfx or a native Android app that captures and sends the audio via UDP.

Not really WLED firmware related as it already has Audioreactive usermod.

still seems to require a physical mic connected to the board, which i'd like to avoid.

You could write a PC software that connects to audioreactive using UDP sound sync. The protocol is described here:

• https://github.com/atuline/WLED/wiki/UDP-Sound-Sync

This protocol delivers pre-processed audio information to WLED, and requires only 44 bytes each 20 milliseconds. There are no plans to create a "full" tcp/ip network based microphone interface for audioreactive.

Update

• there is a module for "chataigne" that can deliver audio data to WLED by UDP sound sync: https://github.com/zak-45/WLEDAudioSync-Chataigne-Module
• For windows, there is WledSRServer (https://github.com/Victoare/SR-WLED-audio-server-win) which is a small application that is doing the audio capturing and sends data to WLED.

Update2

you can also use audioreactive with a line-in board, instead of microphone.
