AudioOutI2S.isPaused()
Description
Query if the input started using play() or loop() has been paused using pause()
Syntax
AudioOutI2S.isPaused();
Returns
1 if input is currently paused, 0 otherwise
Example
/*
This example reads audio data from an Invensense's ICS43432 I2S microphone
breakout board, and prints out the amplitude to the Serial console. The
Serial Plotter built into the Arduino IDE can be used to plot the audio
amplitude data (Tools -> Serial Plotter)
Circuit:
* Arduino/Genuino Zero, MKRZero or MKR1000 board
* ICS43432:
* GND connected GND
* 3.3V connected 3.3V (Zero) or VCC (MKR1000, MKRZero)
* WS connected to pin 0 (Zero) or pin 3 (MKR1000, MKRZero)
* CLK connected to pin 1 (Zero) or pin 2 (MKR1000, MKRZero)
* SD connected to pin 9 (Zero) or pin A6 (MKR1000, MKRZero)
