Package com.sedmelluq.discord.lavaplayer.filter

Class ChannelCountPcmAudioFilter

java.lang.Object

com.sedmelluq.discord.lavaplayer.filter.ChannelCountPcmAudioFilter

All Implemented Interfaces:

AudioFilter, FloatPcmAudioFilter, ShortPcmAudioFilter, SplitShortPcmAudioFilter, UniversalPcmAudioFilter

public class ChannelCountPcmAudioFilter
extends java.lang.Object
implements UniversalPcmAudioFilter

For short PCM buffers, guarantees that the output has the required number of channels and that no outgoing buffer contains any partial frames.

For example if the input is three channels, and output is two channels, then: in [0, 1, 2, 0, 1, 2, 0, 1] out [0, 1, 0, 1] saved [0, 1] in [2, 0, 1, 2] out [0, 1, 0, 1] saved []

Specified by:

process in interface ShortPcmAudioFilter

Parameters:

input - Array of samples

offset - Offset in the array

length - Length of the sequence in the array

Throws:

java.lang.InterruptedException - When interrupted externally (or for seek/stop).

process

             throws java.lang.InterruptedException

Specified by:

process in interface ShortPcmAudioFilter

Parameters:

buffer - The buffer of samples

Throws:

java.lang.InterruptedException - When interrupted externally (or for seek/stop).

process

public void process(float[][] input,

Specified by:

process in interface FloatPcmAudioFilter

Parameters:

input - An array of samples for each channel

offset - Offset in the arrays to start at

length - Length of the target sequence in arrays

Throws:

java.lang.InterruptedException - When interrupted externally (or for seek/stop).

process

public void process(short[][] input,
                    int offset,
                    int length)

seekPerformed

public void seekPerformed(long requestedTime,
                          long providedTime)

Description copied from interface: AudioFilter

Indicates that the next samples are not a continuation from the previous ones and gives the timecode for the next incoming sample.

Specified by:

seekPerformed in interface AudioFilter

Parameters:
