WaveformAudioBufferSink.WaveformBar

Kotlin |Java

public class WaveformAudioBufferSink.WaveformBar

Aggregates a group of audio samples. The values exposed can be used to draw one vertical bar of an audio waveform.

Summary

Public fields
`int`	`sampleCount`

Public constructors
`WaveformBar()`

Public methods
`void`	`addSample(@FloatRange(from = "-1", to = 1) float sample)` Adds a new sample to the group.
`double`	`getMaxSampleValue()` Returns the maximum sample value in this group, normalized between -1 and +1.
`double`	`getMinSampleValue()` Returns the minimum sample value in this group, normalized between -1 and +1.
`double`	`getRootMeanSquare()` Returns the RMS (Root Mean Square) of the samples in this group, normalized between -1 and +1.
`int`	`getSampleCount()` Returns the number of samples `added`.

public int sampleCount

public WaveformBar()

public void addSample(@FloatRange(from = "-1", to = 1) float sample)

Adds a new sample to the group.

Parameters
`@FloatRange(from = "-1", to = 1) float sample`	The sample value, between -1 and +1.

public double getMaxSampleValue()

Returns the maximum sample value in this group, normalized between -1 and +1.

public double getMinSampleValue()

Returns the minimum sample value in this group, normalized between -1 and +1.

public double getRootMeanSquare()

Returns the RMS (Root Mean Square) of the samples in this group, normalized between -1 and +1.

This an estimate of the audio loudness level.

public int getSampleCount()

Returns the number of samples added.
