WaveformAudioBufferSink.WaveformBar

Kotlin |Java

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 constructors
`WaveformBar()`

Public functions
`Unit`	`addSample(sample: @FloatRange(from = "-1", to = 1) Float)` 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.

Public properties
`Int`	`sampleCount`

WaveformBar()

fun addSample(sample: @FloatRange(from = "-1", to = 1) Float): Unit

Adds a new sample to the group.

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

fun getMaxSampleValue(): Double

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

fun getMinSampleValue(): Double

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

fun getRootMeanSquare(): Double

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.
