VectorUchar encodeToBamStream ()
 Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a bytes object. More...
 
bool encodeToBamStream (VectorUchar data, BamWriter writer)
 Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string. More...
 
 fillin (DatagramIterator scan, BamReader manager)
 This internal function is intended to be called by each class's make_from_bam() method to read in all of the relevant data from the BamFile for the new object. More...
 
UpdateSeq getBamModified ()
 Returns the current bam_modified counter. More...
 
 markBamModified ()
 Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. More...

Detailed Description

Class MicrophoneAudio provides the means to read raw audio samples from a microphone.

Member Function Documentation

◆ getChannels()

int getChannels ( )

Returns the number of channels.

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getNumOptions()

static int getNumOptions ( )
static

Returns the number of microphone options.

An "option" consists of a device plus a set of configuration parameters. For example, "Soundblaster Audigy Line in at 44,100 samples/sec" would be an option.

◆ getOption()

static MicrophoneAudio getOption ( int  n)
static

Returns the nth microphone option.

◆ getOptions()

list getOptions ( )

◆ getRate()

int getRate ( )

Returns the sample rate.
