public class AudioNoiseGenerator
extends AbstractSource

InbandGenerator generates Inband DTMF Tone only for uncompressed LINEAR codec. After creating instance of InbandGenerator, it needs to be initialized so that all the Tones are generated and kept ready for transmission once start is called. By default the Tone duration is 80ms. This is suited for Tone Detector who has Tone duration of greater than 40 and less than 80ms. For Tone Detector who's Tone duration is set greater than 80ms may fail to detect Tone generated by InbandGenerator(with duration 80ms). In that case increase the duration here too.

Method Detail

setPreffered

public void setPreffered(org.mobicents.media.Format fmt)

Description copied from class: AbstractSource

This methods is called by media sink to setup preffered format. Media source in opposite direction can ask media sink to get preffered format by calling sink.getPreffred(Collection) where collection is a subset of common formats.

Overrides:

setPreffered in class AbstractSource

Parameters:

fmt - preffred format.

getFormats

public org.mobicents.media.Format[] getFormats()

evolve

public void evolve(org.mobicents.media.Buffer buffer,
                   long timestamp)

Description copied from class: AbstractSource

This method must be overriden by concrete media source. The media have to fill buffer with media data and attributes.

Specified by:

evolve in class AbstractSource

Parameters:

buffer - the buffer object for media.

stop

public void stop()

Description copied from class: AbstractSource

(Non Java-doc).

Specified by:

stop in interface org.mobicents.media.MediaSource

Overrides:

stop in class AbstractSource
