Function encode 

pub fn encode(
    samples: &[f32],
    sample_rate: u32,
    channels: u8,
    bit_depth: u8,
    metadata: Option<Vec<u8>>,
) -> Result<Vec<u8>, JsValue>

encode samples to flo lossless

Arguments

• samples - Interleaved audio samples (f32, -1.0 to 1.0)
• sample_rate - Sample rate in Hz (e.g., 44100)
• channels - Number of channels (1 or 2)
• bit_depth - Bits per sample (16, 24, or 32)
• metadata - Optional MessagePack metadata

Returns

flo™ file as byte array

Note

For advanced usage with custom compression levels (0-9), use the Encoder builder pattern directly.
