Audio Format

The AudioFormat class defines technical specifications for audio data.

AudioFormat

data class AudioFormat(
    val sampleRate: Int,       // Hz
    val channels: Channels,    // Mono or Stereo
    val encoding: SampleEncoding
)

Creating custom formats

val format = AudioFormat(
    sampleRate = 48000,
    channels = Channels.Stereo,
    encoding = SampleEncoding.PcmInt(IntBitDepth.Sixteen)
)

Channels

Mono: Single channel (1)
Stereo: Left and right (2)

Bit depths

Eight: 8-bit (48 dB range)
Sixteen: 16-bit (96 dB range) - standard
TwentyFour: 24-bit (144 dB range) - professional
ThirtyTwo: 32-bit (192 dB range)

Computed properties

bytesPerSample: Bytes for one sample
bytesPerFrame: Bytes for one frame (all channels)
