Method Details

close

public void close()

Explicitly frees any external resource attached to the object.

create

public static AudioProcessingOptions create(int audioProcessingFlags)

Creates an AudioProcessingOptions object with audio processing flags. This method should only be used when the audio input is from a microphone array. On Windows, this method will try to query the microphone array geometry from the audio driver. Audio data is also read from speaker reference channel. On Linux, it assumes that the microphone is a single channel microphone.

Parameters:

audioProcessingFlags - Specifies flags to control the audio processing performed by Speech SDK. It is bitwise OR of constants from AudioProcessingConstants class.

Returns:

The audio processing options object being created.

create

public static AudioProcessingOptions create(int audioProcessingFlags, MicrophoneArrayGeometry microphoneArrayGeometry)

Creates an AudioProcessingOptions object with audio processing flags and custom microphone array geometry.

Parameters:

audioProcessingFlags - Specifies flags to control the audio processing performed by Speech SDK. It is bitwise OR of constants from AudioProcessingConstants class.
microphoneArrayGeometry - Specifies the microphone array geometry.

Returns:

The audio processing options object being created.

create

public static AudioProcessingOptions create(int audioProcessingFlags, MicrophoneArrayGeometry microphoneArrayGeometry, SpeakerReferenceChannel speakerReferenceChannel)

Creates an AudioProcessingOptions object with audio processing flags, custom microphone array geometry and speaker reference channel position.

Parameters:

audioProcessingFlags - Specifies flags to control the audio processing performed by Speech SDK. It is bitwise OR of constants from AudioProcessingConstants class.
microphoneArrayGeometry - Specifies the microphone array geometry.
speakerReferenceChannel - Specifies the speaker reference channel position in the input audio.

Returns:

The audio processing options object being created.

create

public static AudioProcessingOptions create(int audioProcessingFlags, PresetMicrophoneArrayGeometry microphoneArrayGeometry)

Creates an AudioProcessingOptions object with audio processing flags and preset microphone array geometry.

Parameters:

audioProcessingFlags - Specifies flags to control the audio processing performed by Speech SDK. It is bitwise OR of constants from AudioProcessingConstants class.
microphoneArrayGeometry - Specifies the type of microphone array geometry.

Returns:

The audio processing options object being created.

create

public static AudioProcessingOptions create(int audioProcessingFlags, PresetMicrophoneArrayGeometry microphoneArrayGeometry, SpeakerReferenceChannel speakerReferenceChannel)

Creates an AudioProcessingOptions object with audio processing flags, preset microphone array geometry and speaker reference channel position.

Parameters:

audioProcessingFlags - Specifies flags to control the audio processing performed by Speech SDK. It is bitwise OR of constants from AudioProcessingConstants class.
microphoneArrayGeometry - Specifies the type of microphone array geometry.
speakerReferenceChannel - Specifies the speaker reference channel position in the input audio.

Returns:

The audio processing options object being created.

getAudioProcessingFlags

public int getAudioProcessingFlags()

Returns:

Bitwise OR of flags from AudioProcessingConstants class indicating the audio processing performed by Speech SDK.

getBeamformingEndAngle

public int getBeamformingEndAngle()

Returns the end angle used for beamforming.

Returns:

Beamforming end angle.

getBeamformingStartAngle

public int getBeamformingStartAngle()

Returns the start angle used for beamforming.

Returns:

Beamforming start angle.

getImpl

public SafeHandle getImpl()

Returns the audio processing options implementation.
