Remarks
DynamicsProcessing is an audio effect for equalizing and changing dynamic range properties of the sound. It is composed of multiple stages including equalization, multi-band compression and limiter.
The number of bands and active stages is configurable, and most parameters can be controlled in realtime, such as gains, attack/release times, thresholds, etc.
The effect is instantiated and controlled by channels. Each channel has the same basic architecture, but all of their parameters are independent from other channels.
The basic channel configuration is:
Channel 0 Channel 1 .... Channel N-1

Output Output Output
Where the stages are: inputGain: input gain factor in decibels (dB). 0 dB means no change in level. PreEQ: Multi-band Equalizer. MBC: Multi-band Compressor PostEQ: Multi-band Equalizer Limiter: Single band compressor/limiter.
An application creates a DynamicsProcessing object to instantiate and control this audio effect in the audio framework. A DynamicsProcessor.Config and DynamicsProcessor.Config.Builder are available to help configure the multiple stages and each band parameters if desired.
See each stage documentation for further details.
If no Config is specified during creation, a default configuration is chosen.
To attach the DynamicsProcessing to a particular AudioTrack or MediaPlayer, specify the audio session ID of this AudioTrack or MediaPlayer when constructing the effect (see AudioTrack#getAudioSessionId() and MediaPlayer#getAudioSessionId()).
To attach the DynamicsProcessing to a particular AudioTrack or MediaPlayer, specify the audio session ID of this AudioTrack or MediaPlayer when constructing the DynamicsProcessing.
See android.media.MediaPlayer#getAudioSessionId() for details on audio sessions.
See android.media.audiofx.AudioEffect class for more details on controlling audio effects.
