The

options

dictionary in

NoiseCancellationOptions

allows you to pass module-specific configuration options for noise cancellation in LiveKit. However, the specific keys and values you can use in the

options

dictionary depend on the noise cancellation module you are using (for example,

NC

,

BVC

, or

BVCTelephony

). The documentation indicates that

options

is a flexible dictionary intended to pass custom parameters to the audio filter module, but it does not enumerate the standard keys or values supported for each model. In practice, the

options

dictionary is typically used to provide module-specific settings, and its contents should match the schema expected by the selected module. If you are using a particular model and have specific configuration needs (such as aggressiveness, extra filtering, etc.), you would set those as fields in this dictionary as required by that module’s documentation or interface. If you're looking for more details about available keys and values for a specific noise cancellation module, please specify which module you intend to use, or consult the implementation documentation for that module to identify the supported options.
