Namespace: mixer

syngen.audio.mixer

Provides a mastering process and utilities for routing audio into it like a virtual mixing board. Implementations are encouraged to leverage this instead of the main audio destination directly.

Members

(static) master

Exposes the nodes and parameters associated with the mastering process. Here's an overview of its routing:

  • GainNode input
  • BiquadFilterNode highpass
  • BiquadFilterNode lowpass
  • DynamicsCompressorNode limiter
  • GainNode limiter makeup gain
  • GainNode output
  • AudioDestinationNode syngen.audio.context().destination

Methods

(static) createBus() → {GainNode}

Creates a GainNode that's connected to the master input. Implementations can leverage buses to create submixes.

GainNode

(static) rebuildFilters()

Occasionally the master filters can enter an unstable or bad state. When this happens the entire mix can drop out to silence. This provides a solution for replacing them with stable filters. Implementations can proactively check for invalid states with an AnalyserNode or AudioWorkletNode. Beware that the nodes that caused the issue may also need reset.
