How to select another input stream on the go?

[vorosj]

For example I have several possible input streams (adc, generator, Bluetooth a2dp), and a single i2s output.
How can I select the input on the go? I do not need mixing, and don't want to load the uC with the unused streams.

You can dynamically reconfigure the copier with the help of the begin method.

Thank you.
For example I start a Bluetooth and a generator input stream, and an i2s output stream.
If I first configure the copier as a2dp->i2s, then reconfigure copier to generator->i2s, the a2dp task is still receiving and decoding, or it is just sitting in the memory (not using notable computing time)?

Yes it does: I would suggest to call the avrc commands pause() and play() (or maybe set_connected(false) and set_connected(true) ?)

Just a story of a finished project:
I built a hearing aid device for our 101 years old grandmother. :-) It was difficult for her to understand conversation using her normal hearind aid device. But she understand very well the TV using a big headset.
So I built a Bluetooth wireless mic using your great library for a big JBL headset. If we keep the mic close, the sound is clear, without the disturbing noise which she often complained about using the normal hearing aid .
She really likes the new one...
