Additional options for a resampling channel.

Fields

latency_seconds: f64

The amount of latency added in seconds between the input stream and the output stream. If this value is too small, then underflows may occur.

The default value is 0.15 (150 ms).

capacity_seconds: f64

The capacity of the channel in seconds. If this is too small, then overflows may occur. This should be at least twice as large as latency_seconds.

Note, the actual capacity may be slightly smaller due to how the internal sampler processes in chunks.

The default value is 0.4 (400 ms).

overflow_autocorrect_percent_threshold: Option<f64>

If the number of occupied samples in the channel is greater than or equal to (latency_seconds + percent * (capacity_seconds - latency_seconds)), then discard the number of samples needed to bring the number of occupied seconds back down to ResamplingChannelConfig::latency_seconds. This is used to avoid excessive overflows and reduce the percieved audio glitchiness.

The percentage is a value in the range [0.0, 100.0].

Set to None to disable this autocorrecting behavior. If the producer end is being used in a non-realtime context, then this should be set to None.

By default this is set to Some(75.0).

underflow_autocorrect_percent_threshold: Option<f64>

If the number of occupied samples in the channel is below or equal to the given percentage of ResamplingChannelConfig::latency_seconds, then insert the number of zero frames needed to bring the number of occupied samples back up to ResamplingChannelConfig::latency_seconds. This is used to avoid excessive underflows and reduce the percieved audio glitchiness.

The percentage is a value in the range [0.0, 100.0].

Set to None to disable this autocorrecting behavior. If the consumer end is being used in a non-realtime context, then this should be set to None.

By default this is set to Some(25.0).

quality: ResampleQuality

The quality of the resampling alrgorithm to use if needed.

The default value is ResampleQuality::Normal.

subtract_resampler_delay: bool

If true, then the delay of the internal resampler (if used) will be subtracted from the latency_seconds value to keep the perceived latency consistent.

The default value is true.

Trait Implementations

impl Clone for ResamplingChannelConfig

fn clone(&self) -> ResamplingChannelConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResamplingChannelConfig

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

Formats the value using the given formatter.

impl Default for ResamplingChannelConfig

fn default() -> ResamplingChannelConfig

Returns the “default value” for a type.

impl PartialEq for ResamplingChannelConfig

fn eq(&self, other: &ResamplingChannelConfig) -> 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.
