## micromod
Class WaveScaler

    java.lang.Object
      micromod.WaveScaler

public class WaveScaler
extends java.lang.Object

The WaveScaler class reduces the amplitude of audio. The idea is that this could be extended to provide a dithering algorithm in the future. This class only does some simple rounding at the moment.

Constructor Summary
`WaveScaler()`

Method Summary
`void` | `scaleWaves(short[] inputBuffer, int[] outputBuffer, int length, int scale)` Scale the amplitude of signed 16 bit audio in buffer.
`void` | `scaleWavesAccumulate(short[] inputBuffer, int[] outputBuffer, int length, int scale)` As scaleWaves(), except add the output values to those in outputBuffer, instead of overwriting them.

Method Detail

### scaleWaves

    public void scaleWaves(short[] inputBuffer,
                           int[] outputBuffer,
                           int length,
                           int scale)

  Scale the amplitude of signed 16 bit audio in buffer. Perform the operation on indexes 0 to length-1.

  Parameters:
    `inputBuffer` - The audio input buffer.
    `outputBuffer` - The audio output buffer.
    `length` - The number of samples to scale.
    `scale` - The amount to scale the audio by. This is in fixed point format, with 8192 representing a scale factor of 1.0. The maximum scale factor is 8.0

### scaleWavesAccumulate

    public void scaleWavesAccumulate(short[] inputBuffer,
                                     int[] outputBuffer,
                                     int length,
                                     int scale)

  As scaleWaves(), except add the output values to those in outputBuffer, instead of overwriting them. This method is good for efficiency.
