This file contains wrappers for AudioBuffer and AnalyserNode related calls * https://developer.mozilla.org/en-US/docs/Web/API/AudioBuffer * https://developer.mozilla.org/en-US/docs/Web/API/AnalyserNode

The goal is to prevent fingerprinting by modifying the values from functions which are reading/copying from AudioBuffer and AnalyserNode. So the audio content of wrapped objects is the same as intended.

The modified content can be either a white noise based on domain key or a fake audio data that is modified according to domain key to be different than the original albeit very similar (i.e. the approach inspired by the algorithms created by Brave Software https://brave.com available at https://github.com/brave/brave-core/blob/master/chromium_src/third_party/blink/renderer/core/execution_context/execution_context.cc.)

Note: Both approaches are detectable by a fingerprinter that checks if a predetermined audio is the same as the read one. Nevertheless, the aim of the wrappers is to limit the finerprintability.

Known bug: Possibly inconsistant data between AudioBuffer and AnalyserNode wrappers.

Known bug: Inconsistency between AudioBuffer.prototype.copyFromChannel and AudioBuffer.prototype.getChannelData. AudioBuffer.prototype.copyFromChannel should call AudioBuffer.prototype.getChannelData wrapper and then return result of the original call.
