Waits for a specified amount of noise.


Waits for up to noiserequired milliseconds of noise, iterations times. An optional timeout specified the number of seconds to return after, even if we do not receive the specified amount of noise. Use timeout with caution, as it may defeat the purpose of this application, which is to wait indefinitely until noise is detected on the line.


  • noiserequired - If not specified, defaults to 1000 milliseconds.
  • iterations - If not specified, defaults to 1.
  • timeout - Is specified only to avoid an infinite loop in cases where silence is never achieved.
