Methods

static analyze(frequencyContent) → {Uint8Array}
analyses/PowerSpectrum.mjs, line 29

Performs a power spectrum analysis on the passed-in buffer containing audio frequency content. The bins of the resulting power spectrum will contain values between [0, 255], where 0 represents silence and 255 represents the maximum representable power.

Parameters:
Name Type Description
frequencyContent Uint8Array

Uint8Array containing audio frequency data
Returns:
Uint8Array -

Array containing the power spectrum corresponding to the specified frequency data as values between [0, 255]
