All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

AndroidAudioData, AudioBuffer, AudioStream

public abstract class AudioData
extends NativeObject

AudioData is an abstract representation of audio data. There are two ways to handle audio data, short audio files are to be stored entirely in memory, while long audio files (music) are streamed from the hard drive as they are played.

Method Detail

getDataType

public abstract AudioData.DataType getDataType()

Returns:

The data type, either Buffer or Stream.

getDuration

public abstract float getDuration()

Returns:

the duration in seconds of the audio clip.

getBitsPerSample

public int getBitsPerSample()

Returns:

Bits per single sample from a channel.

getChannels

public int getChannels()

Returns:

Number of channels. 1 for mono, 2 for stereo, etc.

getSampleRate

public int getSampleRate()

Returns:

The sample rate, or how many samples per second.
