Function render_stereo 

pub fn render_stereo<S>(
    initial_state: S,
    sample_rate: u32,
    num_samples: usize,
    step: impl Fn(S, f64) -> ((f32, f32), S),
) -> Vec<(f32, f32)>

Render a stereo audio buffer by folding a pure step function over time.

Identical to render but the step function produces a (left, right) sample pair per frame. Returns interleaved [(L0, R0), (L1, R1), ...].

Arguments

• initial_state — starting DSP state
• sample_rate — samples per second
• num_samples — number of stereo frames to generate
• step — pure function: (state, t) → ((left, right), next_state)

Returns

Vec<(f32, f32)> of num_samples stereo frames.

Example

use prime_render::render_stereo;

// Constant stereo frame — left=0.5, right=-0.5
let frames = render_stereo((), 44100, 3, |s, _t| ((0.5, -0.5), s));
assert_eq!(frames, vec![(0.5, -0.5), (0.5, -0.5), (0.5, -0.5)]);
