Struct replaygain::ReplayGain

pub struct ReplayGain { /* private fields */ }

Implementations

impl ReplayGain

pub fn new(sample_rate: usize) -> Option<ReplayGain>

Create a new ReplayGain filter for the given sample rate. Returns None if the sample rate is not supported.

pub fn frame_size(&self) -> usize

Returns the size of a single audio frame (one of which we analyze at a time) in floats. Note that because we expect stereo audio, this means that you need to divide this by 2 to get the number of samples.

pub fn process_frame(&mut self, frame: &[f32])

Processes a single audio frame.

Panics

Panics if frame.len() != self.frame_size() or if there’s anything in process_samples’s buffer. If you need buffering, use process_samples() and only that instead.

pub fn process_samples(&mut self, frame: &[f32])

Processes a given amount of audio samples.

Note that because we expect stereo audio, it doesn’t actually make sense to pass an odd number of floats to this function but we buffer it to chunks of frame_size() anyways so we don’t care.

pub fn finish(self) -> (f32, f32)

Completes the analysis and returns the two replaygain values (gain, peak).
