Implementations

impl Converter

pub fn new(dither_config: Option<DithererBuilder>) -> Self

pub fn scale(&mut self, sample: f64, shift: u8) -> f64

Scale audio samples with optimal dithering strategy for Spotify’s 16-bit source material.

Since Spotify audio is always 16-bit depth, this function:

1. When dithering: applies noise at 16-bit level, preserves fractional precision, then scales to target format and rounds once at the end
2. When not dithering: scales directly from normalized float to target format

The shift parameter specifies how many extra bits to shift beyond the base 16-bit scaling (0 for 16-bit, 8 for 24-bit, 16 for 32-bit).

pub fn clamping_scale_s24(&mut self, sample: f64) -> f64

Clamping scale specifically for 24-bit output to prevent MSB overflow. Only used for S24 formats where samples are packed in 32-bit words. Ensures the most significant byte is zero to prevent overflow during dithering.

pub fn f64_to_f32(&mut self, samples: &[f64]) -> Vec<f32>

pub fn f64_to_s32(&mut self, samples: &[f64]) -> Vec<i32>

pub fn f64_to_s24(&mut self, samples: &[f64]) -> Vec<i32>

S24 is 24-bit PCM packed in an upper 32-bit word

pub fn f64_to_s24_3(&mut self, samples: &[f64]) -> Vec<i24>

S24_3 is 24-bit PCM in a 3-byte array

pub fn f64_to_s16(&mut self, samples: &[f64]) -> Vec<i16>
