start

public void start()

Description copied from interface: MinimServiceProvider

Called inside the Minim constructor. Implementations should load any libraries and resources they need at this time.

Specified by:

start in interface MinimServiceProvider

stop

public void stop()

Description copied from interface: MinimServiceProvider

Called when stop() is called by the Minim object that owns this. Implementations should release all resources and stop all Threads at this time.

Specified by:

stop in interface MinimServiceProvider

debugOn

public void debugOn()

Description copied from interface: MinimServiceProvider

Tells the implementation it should produce debug output, if that's something it does.

Specified by:

debugOn in interface MinimServiceProvider

debugOff

public void debugOff()

Description copied from interface: MinimServiceProvider

Tells the implementation it should not produce debug output.

Specified by:

debugOff in interface MinimServiceProvider

getSampleRecorder

public SampleRecorder getSampleRecorder(Recordable source,
                                        java.lang.String fileName,
                                        boolean buffered)

Description copied from interface: MinimServiceProvider

Should return a SampleRecorder that can record the source in a buffered (in-memory) or non-buffered (streamed) manner, to the file specified by saveTo

Specified by:

getSampleRecorder in interface MinimServiceProvider

Parameters:

source - the audio source that should be recorded

fileName - the file to save the recorded audio to

buffered - whether or not to buffer all recorded audio in memory or stream directly to the file

Returns:

an appropriate SampleRecorder

getAudioRecordingStream

public AudioRecordingStream getAudioRecordingStream(java.lang.String filename,
                                                    int bufferSize,
                                                    boolean inMemory)

Description copied from interface: MinimServiceProvider

Should return an AudioRecordingStream that will stream the file requested. The filename could be a URL, an absolute path, or just a filename that the user expects the system to find in their sketch somewhere.

Specified by:

getAudioRecordingStream in interface MinimServiceProvider

Parameters:

filename - the name of the file to load into the AudioRecordingStream

bufferSize - the bufferSize to use in memory (implementations are free to ignore this, if they must)

inMemory - TODO

Returns:

an AudioRecording stream that will stream the file

getAudioInput

public AudioStream getAudioInput(int type,
                                 int bufferSize,
                                 float sampleRate,
                                 int bitDepth)

Description copied from interface: MinimServiceProvider

Should return an AudioStream with the requested parameters. What Minim is expecting this stream to be reading from is the active audio input of the computer, such as the microphone or line-in.

Specified by:

getAudioInput in interface MinimServiceProvider

Parameters:

type - Minim.STEREO or Minim.MONO

bufferSize - how big the in-memory buffer should be

sampleRate - what the sample rate of the stream should be

bitDepth - what the bit depth of the stream should be

Returns:

an AudioStream that is reading from the active audio input of the computer
