com.google.android.exoplayer2 is deprecated. Please migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.

An AudioProcessor that handles mixing and scaling audio channels. Call putChannelMixingMatrix(ChannelMixingMatrix) specifying mixing matrices to apply for each possible input channel count before using the audio processor. Input and output are 16-bit PCM.

Modifier and Type	Method	Description
`protected AudioProcessor.AudioFormat`	`onConfigure(AudioProcessor.AudioFormat inputAudioFormat)`	Deprecated. Called when the processor is configured for a new input format.
`void`	`putChannelMixingMatrix(ChannelMixingMatrix matrix)`	Deprecated. Stores a channel mixing matrix for processing audio with a given `channel count`.
`void`	`queueInput(ByteBuffer inputBuffer)`	Deprecated. Queues audio data between the position and limit of the `inputBuffer` for processing.

  - queueInput

public void queueInput(ByteBuffer inputBuffer)
```
    Deprecated.
    
    Description copied from interface: AudioProcessor
    
    Queues audio data between the position and limit of the inputBuffer for processing. After calling this method, processed output may be available via AudioProcessor.getOutput(). Calling queueInput(ByteBuffer) again invalidates any pending output.
    
    Parameters:
    
    inputBuffer - The input buffer to process. It must be a direct byte buffer with native byte order. Its contents are treated as read-only. Its position will be advanced by the number of bytes consumed (which may be zero). The caller retains ownership of the provided buffer.
