int getEncoding

(

)

Returns the encoding format.

Returns

android.media.AudioFormat.ENCODING_PCM_8BIT or android.media.AudioFormat.ENCODING_PCM_16BIT.

getFrequency()

int getFrequency

(

)

Returns sampling frequency.

Returns

sampling frequency.

getNoiseReduction()

boolean getNoiseReduction

(

)

Tests if the noise reduction filter is enabled.

Returns

true : the noise reduction filter is enabled. false : the noise reduction filter is disabled.

Sets noise reduction filter.
If b sets true before calling startInStream() , the noise reduction filter is enabled. It cannot be siwtched while streaming.

Parameters

b	true : Enables the noise reduction filter false : Disables the noise reduction filter.

startInStream()

void startInStream	(	int	freq,
		int	channels,
		int	subSampling,
		Callback	cb
	)		throws OwliftException

Starts input sound streaming.
Note: due to hardware restriction, there is a possibility to be changed each parameters. To get current setting parameters, uses some methods ( for example, getFrequency()) after execute this method.

Parameters

freq	sampling frequency.
channels	number of channels.
subSampling	number of byte per 1 sample/channel.
cb	Callback. (null available).
