Struct EqualizerFeature 

pub struct EqualizerFeature { /* private fields */ }

Implements the Equalizer / 0x8310 feature.

Implementations

impl EqualizerFeature

pub async fn get_eq_info(&self) -> Result<EqInfo, Hidpp20Error>

Retrieves the EQ table’s band count, gain range and storage capabilities.

pub async fn get_frequencies( &self, band_count: u8, ) -> Result<Vec<u16>, Hidpp20Error>

Retrieves the frequency (Hz) of every band.

band_count is the value from EqInfo::band_count; the device returns up to seven frequencies per response, so this pages through them until all band_count are collected.

pub async fn get_frequency_gains( &self, location: GainLocation, band_count: u8, ) -> Result<Vec<i8>, Hidpp20Error>

Retrieves the active gain (dB) of every band from location.

band_count is the value from EqInfo::band_count (at most 15, the number of gains a single response carries).

pub async fn set_frequency_gains( &self, persistence: GainPersistence, gains: &[i8], ) -> Result<Vec<i8>, Hidpp20Error>

Sets the per-band gains (dB) and returns the device’s echo of them.

gains holds one signed value per band (at most 15). The device rejects out-of-range gains.

pub async fn get_mic_noise_reduction(&self) -> Result<bool, Hidpp20Error>

Retrieves whether hardware microphone noise reduction is enabled.

pub async fn set_mic_noise_reduction( &self, enabled: bool, ) -> Result<(), Hidpp20Error>

Enables or disables hardware microphone noise reduction.
