Открытые методы

Метод Описание
GetDevice ( ) : string

Get the name of the current audio capture device

SetDevice ( string Name ) : bool

Set the audio capture device

SoundRecorder ( ) : System

Default constructor

Start ( ) : bool

Start the capture using the default sample rate (44100 Hz). Please note that only one capture can happen at the same time.

Start ( uint sampleRate ) : bool

Start the capture. The sampleRate parameter defines the number of audio samples captured per second. The higher, the better the quality (for example, 44100 samples/sec is CD quality). This function uses its own thread so that it doesn't block the rest of the program while the capture runs. Please note that only one capture can happen at the same time.

Stop ( ) : void

Stop the capture

ToString ( ) : string

Provide a string describing the object

Защищенные методы

Метод Описание
Destroy ( bool disposing ) : void

Handle the destruction of the object

OnProcessSamples ( short samples ) : bool

Process a new chunk of recorded samples. This virtual function is called every time a new chunk of recorded data is available. The derived class can then do whatever it wants with it (storing it, playing it, sending it over the network, etc.).

OnStart ( ) : bool

Start capturing audio data. This virtual function may be overridden by a derived class if something has to be done every time a new capture starts. If not, this function can be ignored; the default implementation does nothing.

OnStop ( ) : void

Stop capturing audio data. This virtual function may be overridden by a derived class if something has to be done every time the capture ends. If not, this function can be ignored; the default implementation does nothing.

SetProcessingInterval ( Time interval ) : void

The processing interval controls the period between calls to the onProcessSamples function. You may want to use a small interval if you want to process the recorded data in real time, for example. Note: this is only a hint, the actual period may vary. So don't rely on this parameter to implement precise timing. The default processing interval is 100 ms.

Destroy() защищенный Метод

Handle the destruction of the object
protected Destroy ( bool disposing ) : void
disposing bool Is the GC disposing the object, or is it an explicit call ?
Результат void

GetDevice() публичный Метод

Get the name of the current audio capture device
public GetDevice ( ) : string
Результат string

OnProcessSamples() защищенный абстрактный Метод

Process a new chunk of recorded samples. This virtual function is called every time a new chunk of recorded data is available. The derived class can then do whatever it wants with it (storing it, playing it, sending it over the network, etc.).
protected abstract OnProcessSamples ( short samples ) : bool
samples short Array of samples to process
Результат bool

OnStart() защищенный Метод

Start capturing audio data. This virtual function may be overridden by a derived class if something has to be done every time a new capture starts. If not, this function can be ignored; the default implementation does nothing.
protected OnStart ( ) : bool
Результат bool

OnStop() защищенный Метод

Stop capturing audio data. This virtual function may be overridden by a derived class if something has to be done every time the capture ends. If not, this function can be ignored; the default implementation does nothing.
protected OnStop ( ) : void
Результат void

SetDevice() публичный Метод

Set the audio capture device
public SetDevice ( string Name ) : bool
Name string The name of the audio capture device
Результат bool

SetProcessingInterval() защищенный Метод
