inlinevirtual

Member Function Documentation

connect()

virtual int connect ( )

pure virtual

Implemented in AlsaAudioDriver, CoreAudioDriver, DiskWriterDriver, FakeDriver, JackAudioDriver, NullDriver, OssDriver, PortAudioDriver, and PulseAudioDriver.

disconnect()

virtual void disconnect ( )

getBufferSize()

virtual unsigned getBufferSize ( )

Approximate audio latency (in frames) A reasonable approximation is the buffer time on most audio systems.

For systems with variable buffer sizes, this isn't very useful though

Reimplemented in CoreAudioDriver, and PortAudioDriver.
