Returns a list of settings for the profile `profile` that can usefully be exposed to a user. This usually means just bitrate/quality settings. This works by finding the name of the encoder element for the profile and retrieving a list specific to that encoder.

`profile` : | a GstEncodingProfile
Returns : | list of settings. [transfer full][element-type GParamSpec]

Applies the preset `preset` to the audio encoding profile within `profile`.

`profile` : | a GstEncodingProfile
`preset` : | preset to apply
