Transform Streams Reference
$3
Performs fast fourier transform on incoming (pre-windowed signal chunks). Output signal chunks are
SpectralBuffers.
$3
Take overlapping (or spaced) windows from a continuous time domain audio signal.
$3
Inverse fast fourier transform.
$3
Calculates the mean square (
(∑x^2)/n) of each signal chunk.
$3
Band pass filter using moving average hi/lo pass filters. Neither efficient nor effective, kept to support DeepDrive waveform scripts.
$3
Calculates band intensities for multiple frequency bands using a set of
MovingAverageBandPassFilters in parallel.
$3
Calculate the root mean square of each incoming signal chunk.
