C# Класс Accord.DirectSound.AudioCaptureDevice

Audio source for local audio capture device (i.e. a microphone).

This audio source captures audio data obtained from a local audio capture device such as the microphone. The audio is captured using DirectSound through SlimDX.

For instructions on how to list capture devices, please see the AudioDeviceCollection documentation page.

Открытые методы

Метод	Описание
AudioCaptureDevice ( ) : Accord.Audio	Initializes a new instance of the AudioCaptureDevice class.
AudioCaptureDevice ( AudioDeviceInfo device ) : Accord.Audio	Initializes a new instance of the AudioCaptureDevice class.
AudioCaptureDevice ( System.Guid device ) : Accord.Audio	Initializes a new instance of the AudioCaptureDevice class.
AudioCaptureDevice ( System.Guid device, string name ) : Accord.Audio	Initializes a new instance of the AudioCaptureDevice class.
Dispose ( ) : void	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
Seek ( int frameIndex ) : void	This source does not support seeking.
SignalToStop ( ) : void	Signals audio source to stop its work. Signals audio source to stop its background thread, stop to provide new frames and free resources.
Start ( ) : void	Start audio source. Starts audio source and return execution to caller. audio source object creates background thread and notifies about new frames with the help of NewFrame event.
Stop ( ) : void	Stop audio source. Stops audio source aborting its thread. Since the method aborts background thread, its usage is highly not preferred and should be done only if there are no other options. The correct way of stopping camera is signaling it stop and then waiting for background thread's completion.
WaitForStop ( ) : void	Wait for audio source has stopped. Waits for source stopping after it was signaled to stop using SignalToStop method.

Dispose() публичный Метод

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public Dispose ( ) : void
Результат	void

Dispose() защищенный Метод

Releases unmanaged and - optionally - managed resources

protected Dispose ( bool disposing ) : void
disposing	bool	/// true to release both managed and unmanaged resources; /// false to release only unmanaged resources.
Результат	void

OnNewFrame() защищенный Метод

Notifies client about new block of frames.

protected OnNewFrame ( Array frame ) : void
frame	System.Array	New frame's audio.
Результат	void

Seek() публичный Метод

This source does not support seeking.

public Seek ( int frameIndex ) : void
frameIndex	int
Результат	void

SignalToStop() публичный Метод

Signals audio source to stop its work.

Signals audio source to stop its background thread, stop to provide new frames and free resources.

public SignalToStop ( ) : void
Результат	void

Start() публичный Метод

Start audio source.

Starts audio source and return execution to caller. audio source object creates background thread and notifies about new frames with the help of NewFrame event.

public Start ( ) : void
Результат	void

Stop() публичный Метод

Stop audio source.

Stops audio source aborting its thread.

Since the method aborts background thread, its usage is highly not preferred and should be done only if there are no other options. The correct way of stopping camera is signaling it stop and then waiting for background thread's completion.

Результат	void

WaitForStop() публичный Метод

Wait for audio source has stopped.

Waits for source stopping after it was signaled to stop using SignalToStop method.

public WaitForStop ( ) : void
Результат	void
