const std::optional<uint64_t> & id ()

Unique ID for the band. Must match one of the `id`s specified in `Equalizer` `bands`.

Required.

::std::optional<uint64_t> & id ()

Unique ID for the band. Must match one of the `id`s specified in `Equalizer` `bands`.

Required.

EqualizerBandState & id (std::optional<uint64_t> value)

Unique ID for the band. Must match one of the `id`s specified in `Equalizer` `bands`.

Required.

const std::optional< ::fuchsia_hardware_audio_signalprocessing::EqualizerBandType> & type ()

Type of band.

Required.

If this is a call to `SetElementState`, then the corresponding `SUPPORTS_TYPE_...`

`EqualizerSupportedControls` bit for `type` must be set in `Element.supported_controls`.

::std::optional< ::fuchsia_hardware_audio_signalprocessing::EqualizerBandType> & type ()

Type of band.

Required.

If this is a call to `SetElementState`, then the corresponding `SUPPORTS_TYPE_...`

`EqualizerSupportedControls` bit for `type` must be set in `Element.supported_controls`.

EqualizerBandState & type (std::optional< ::fuchsia_hardware_audio_signalprocessing::EqualizerBandType> value)

Type of band.

Required.

If this is a call to `SetElementState`, then the corresponding `SUPPORTS_TYPE_...`

`EqualizerSupportedControls` bit for `type` must be set in `Element.supported_controls`.

const std::optional<uint32_t> & frequency ()

Center frequency for the band.

Required.

If this is a call to `SetElementState` and represents a change in this band's frequency,

then `CAN_CONTROL_FREQUENCY` must be set in `Element.supported_controls`.

::std::optional<uint32_t> & frequency ()

Center frequency for the band.

Required.

If this is a call to `SetElementState` and represents a change in this band's frequency,

then `CAN_CONTROL_FREQUENCY` must be set in `Element.supported_controls`.

EqualizerBandState & frequency (std::optional<uint32_t> value)

Center frequency for the band.

Required.

If this is a call to `SetElementState` and represents a change in this band's frequency,

then `CAN_CONTROL_FREQUENCY` must be set in `Element.supported_controls`.

const std::optional<float> & q ()

Quality factor, usually denoted as "Q".

Indicates how narrow the frequency transition is. Higher Q values imply narrower

notches/peaks and steeper cuts/shelves. Must be positive.

Optional.

If used in `SetElementState` and represents a change in this band's q, then `CAN_CONTROL_Q`

must be set in `Element.supported_controls`. Must be finite.

::std::optional<float> & q ()

Quality factor, usually denoted as "Q".

Indicates how narrow the frequency transition is. Higher Q values imply narrower

notches/peaks and steeper cuts/shelves. Must be positive.

Optional.

If used in `SetElementState` and represents a change in this band's q, then `CAN_CONTROL_Q`

must be set in `Element.supported_controls`. Must be finite.

EqualizerBandState & q (std::optional<float> value)

Quality factor, usually denoted as "Q".

Indicates how narrow the frequency transition is. Higher Q values imply narrower

notches/peaks and steeper cuts/shelves. Must be positive.

Optional.

If used in `SetElementState` and represents a change in this band's q, then `CAN_CONTROL_Q`

must be set in `Element.supported_controls`. Must be finite.

const std::optional<float> & gain_db ()

Gain in dB.

Required, for `EqualizerBandType` of `PEAK`, `LOW_SHELF` and `HIGH_SHELF`. Must be finite.

Disallowed, for `EqualizerBandType` of `NOTCH`, `LOW_CUT` and `HIGH_CUT`.

::std::optional<float> & gain_db ()

Gain in dB.

Required, for `EqualizerBandType` of `PEAK`, `LOW_SHELF` and `HIGH_SHELF`. Must be finite.

Disallowed, for `EqualizerBandType` of `NOTCH`, `LOW_CUT` and `HIGH_CUT`.

EqualizerBandState & gain_db (std::optional<float> value)

Gain in dB.

Required, for `EqualizerBandType` of `PEAK`, `LOW_SHELF` and `HIGH_SHELF`. Must be finite.

Disallowed, for `EqualizerBandType` of `NOTCH`, `LOW_CUT` and `HIGH_CUT`.

const std::optional<bool> & enabled ()

Enable/disable the band.

If disabled, audio still flows through the equalizer but this band has no effect.

If absent in the return value from `WatchElementState`, the band is enabled.

If omitted in a `SetElementState` call, the band's enable/disable state is unchanged.

Bypassing the entire enclosing processing element (by setting `ElementState.bypassed` to

true) does not change this field's value, although for an equalizer band to be functional,

its enclosing equalizer processing element must be both started and not bypassed.

Optional.

::std::optional<bool> & enabled ()

Enable/disable the band.

If disabled, audio still flows through the equalizer but this band has no effect.

If absent in the return value from `WatchElementState`, the band is enabled.

If omitted in a `SetElementState` call, the band's enable/disable state is unchanged.

Bypassing the entire enclosing processing element (by setting `ElementState.bypassed` to

true) does not change this field's value, although for an equalizer band to be functional,

its enclosing equalizer processing element must be both started and not bypassed.

Optional.

EqualizerBandState & enabled (std::optional<bool> value)

Enable/disable the band.

If disabled, audio still flows through the equalizer but this band has no effect.

If absent in the return value from `WatchElementState`, the band is enabled.

If omitted in a `SetElementState` call, the band's enable/disable state is unchanged.

Bypassing the entire enclosing processing element (by setting `ElementState.bypassed` to

true) does not change this field's value, although for an equalizer band to be functional,
