Re-exports§

AudioTap: Lock-free single-producer/single-consumer sample tap for the audio → UI analyzer path (audio→UI sample ring).
BoolParam: A boolean parameter.
EnumParam: An enum parameter.
FloatParam: A continuous floating-point parameter.
IntParam: An integer parameter.
MeterSlot: A meter slot with an auto-assigned ID.
ParamFlags
ParamInfo: Metadata for a single parameter, used by format wrappers.
Smoother: Per-parameter smoother. All methods take &self for interior mutability, enabling use through Arc<Params>.

MidiSource: MIDI message kind for ParamInfo::midi_map hints.
ParamRange: Defines how a parameter maps between plain and normalized values.
ParamUnit
ParamValueKind: Which strongly-typed *Param constructor produced this ParamInfo. The #[derive(Params)] macro sets it from the field type so format-side code can branch on the original typing without re-deriving it from range / unit.
SmoothingStyle: Smoothing style for a parameter.

DEFAULT_TAP_CAPACITY: Default ring capacity in samples for AudioTap::default - two typical 2048-point analyzer FFT windows’ worth of headroom so a slightly late UI drain doesn’t lose a whole frame.

FloatParamReadF32: Precision-routed read accessors for FloatParam at f32.
FloatParamReadF64: Precision-routed read accessors for FloatParam at f64. See FloatParamReadF32 for the contract.
ParamEnum: Trait for enums used as parameters.
Params: Trait implemented by #[derive(Params)] on a struct. Format wrappers use this to enumerate, read, and write parameters.

format_param_value: Format a plain parameter value as a display string based on the parameter’s unit.
map_source_to_param: Resolve which parameter a MIDI source on channel is bound to from a param-info list (first match; derive rejects overlaps). Helper for tooling — format wrappers do not call this.
parse_param_value: Inverse of format_param_value for host text_to_value round-trips.
