Class tksdl.AudioDevice

• core.Object

• closeDSP() - Close sound device
• enableFileOutput(boolean bEnabled) - Enable/disable file output
• finishBlock() - Finally send sample block to audio device
• getBpm() : float - Query beats per minute
• getPpq() : int - Query precision per quarter
• getSwapstereo() : boolean - Query whether stereo channels are swapped
• getVolume() : float - Query master volume
• openDSP(float freq, int bufSize) : boolean - Open sound device with the given parameters
• processTimeFrames() - Trigger onAudioFrame(), onAudioRender() signal callbacks
• setBpm(float bpm) - Set beats per minute
• setDefaultBufferSize(int bufSize) - Set output buffer size (and thus audio latency). Warning: Not all drivers can handle small buffer sizes. The default buffer size is 8192 samples
• setFileName(String fileName) - Where to write the sample data when file output is enabled
• setPpq(int ppq) - Set precision per quarter
• setSwapstereo(boolean b) - Enable stereo channel swapping
• setVolume(float f) - Set master volume for sample mixer.
• start() - Start sound output
• stop() - Stop sound output

This class emits the following signals:
onAudioFrame() - called whenever a new frame (according to PPQ and BPM) starts
onAudioPostProcess(FloatArray buf) - Called when a block of samples is about to be sent to the output device
onAudioRender(FloatArray buf) - Called when a new sample frame needs to be rendered
onAudioBeginBlock(FloatArray buf) - Called when a new block of samples needs to be rendered. The application may decide to call processTimeFrames() to trigger the onAudioFrame() and onAudioRender() callbacks. Note: This function runs in a separate thread.
