Class HasAvailableOutputDevice

java.lang.Object
  micromod.output.PCM16StreamOutputDevice
      micromod.output.HasAvailableOutputDevice

All Implemented Interfaces:

OutputDevice, PCM16, StreamOutputDevice

Direct Known Subclasses:

JavaSoundOutputDevice

public abstract class HasAvailableOutputDevice

extends PCM16StreamOutputDevice

A HasAvailableOutputDevice has an internal buffer whose status can be determined at any time. All stream devices have such a buffer, but some may not support the ability to request the amount of data within it.

Method Detail

bytesAvailable

protected abstract int bytesAvailable()

Returns:

The number of bytes available in the buffer.

framesAvailable

public int framesAvailable()

A frame of PCM audio is one sample. Eg) 1 frame is 4 bytes with 16 bit stereo audio.

Returns:

the number of frames of audio that can be written directly to the buffer without "blocking" (having to wait until the space becomes available)
