Function convert_f0 

pub fn convert_f0(
    f0_contour: &[f32],
    source_mean: f32,
    source_std: f32,
    target_mean: f32,
    target_std: f32,
) -> Vec<f32>

Convert F0 (fundamental frequency) contour from source to target speaker.

Arguments

• f0_contour - Source F0 values in Hz (0.0 for unvoiced)
• source_mean - Mean F0 of source speaker
• source_std - Standard deviation of source F0
• target_mean - Mean F0 of target speaker
• target_std - Standard deviation of target F0

Returns

Converted F0 contour
