LTC encoder

Implementations

impl LtcEncoder

pub fn new(sample_rate: u32, frame_rate: FrameRate, amplitude: f32) -> Self

Create a new LTC encoder

pub fn encode_frame( &mut self, timecode: &Timecode, ) -> Result<Vec<f32>, TimecodeError>

Encode a timecode frame to audio samples

pub fn encode_batch(timecodes: &[Timecode], sample_rate: u32) -> Vec<Vec<i16>>

Encode multiple timecodes in a single batch call.

Returns one inner Vec<i16> per timecode, each holding one LTC frame worth of PCM samples at the given sample_rate. The i16 samples are scaled from amplitude (0.0 – 1.0): +amplitude → i16::MAX, −amplitude → i16::MIN.

A fresh encoder polarity state is used for each timecode, matching the per-frame reset semantics that many LTC editors expect.

pub fn encode_batch_interleaved( timecodes: &[Timecode], sample_rate: u32, ) -> Vec<i16>

Encode multiple timecodes and interleave all resulting PCM samples into a single flat Vec<i16>.

Equivalent to calling encode_batch and flattening the result, but avoids an intermediate allocation per frame.

pub fn reset(&mut self)

Reset encoder state

pub fn set_amplitude(&mut self, amplitude: f32)

Set output amplitude

pub fn amplitude(&self) -> f32

Get current amplitude
