Enum GainControllerMode 

pub enum GainControllerMode {
    AdaptiveAnalog,
    AdaptiveDigital,
    FixedDigital,
}

Gain control mode.

Variants

AdaptiveAnalog

Adaptive mode intended for use if an analog volume control is available on the capture device. It will require the user to provide coupling between the OS mixer controls and AGC through the stream_analog_level() functions. It consists of an analog gain prescription for the audio device and a digital compression stage.

AdaptiveDigital

Adaptive mode intended for situations in which an analog volume control is unavailable. It operates in a similar fashion to the adaptive analog mode, but with scaling instead applied in the digital domain. As with the analog mode, it additionally uses a digital compression stage.

FixedDigital

Fixed mode which enables only the digital compression stage also used by the two adaptive modes. It is distinguished from the adaptive modes by considering only a short time-window of the input signal. It applies a fixed gain through most of the input level range, and compresses (gradually reduces gain with increasing level) the input signal at higher levels. This mode is preferred on embedded devices where the capture signal level is predictable, so that a known gain can be applied.

Trait Implementations

impl Clone for GainControllerMode

fn clone(&self) -> GainControllerMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GainControllerMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GainControllerMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for GainControllerMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl IntoEnumIterator for GainControllerMode

type Iterator = GainControllerModeIter

fn iter() -> GainControllerModeIter

impl JsonSchema for GainControllerMode

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for GainControllerMode

fn eq(&self, other: &GainControllerMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for GainControllerMode
