Parameters:

parameter - The audio parameter of LiveSound that has changed. The value of parameter should be one of LiveSoundEvent.SAMPLE_RATE, LiveSoundEvent.CHANNELS, LiveSoundEvent.BUFFER_SIZE, or LiveSoundEvent.BITS_PER_SAMPLE.

Method Detail

getSoundParameter

public int getSoundParameter()

Return the parameter of LiveSound that has changed. The corresponding method of LiveSound may then be invoked do discover the new value of the parameter. For example, if a sample rate change occurs, then this method will return LiveSoundEvent.SAMPLE_RATE. The getSampleRate() method of LiveSound may then be invoked to discover the new value of the sample rate.

Returns:

SAMPLE_RATE, CHANNELS, BUFFER_SIZE, or BITS_PER_SAMPLE.
