renderInterleaved method

void renderInterleaved(
  1. List<double> destination, {
  2. int offset = 0,
  3. int? length,
})
Renders the waveform as a stereo interleaved signal. The audio renderer. The destination buffer.

Implementation

void renderInterleaved(List<double> destination, {int offset = 0, int? length})
{
    if (destination.length % 2 != 0)
    {
        throw "The length of the destination buffer must be even.";
    }

    int sampleCount = 0;

    if (length != null) {
      sampleCount = length;
    } else {
      sampleCount = destination.length ~/ 2;
      sampleCount -= offset;
    }

    List<double> left = List<double>.filled(sampleCount, 0);
    List<double> right = List<double>.filled(sampleCount, 0);

    render(left, right);

    for (var t = 0; t < sampleCount; t++)
    {
        destination[offset + t * 2 + 0] = left[t];
        destination[offset + t * 2 + 1] = right[t];
    }
}
