Implementations

[src]

impl Samples

[src]

pub fn from_bytes(header: &Header, bytes: &[u8]) -> Result<Self, Error>

Create new Samples instance from a slice of bytes this requires a Header instance to be passed to determine the sample size and channel data etc.

Examples

use wavv::{Header, Samples};

fn main() {
    let bytes = [
        0x01, 0x00, // audio format
        0x01, 0x00, // num channels
        0x44, 0xac, 0x00, 0x00, // sample rate
        0x88, 0x58, 0x01, 0x00, // byte rate
        0x04, 0x00, // block align
        0x18, 0x00, // bits per sample
    ];

    let header = Header::from_bytes(&bytes).unwrap();

    assert_eq!(header.num_channels, 1);
    assert_eq!(header.bit_depth, 24);
    assert_eq!(header.sample_rate, 44_100);

    let bytes = [
        0x00, 0x00, 0x00, // sample 1
        0x00, 0x24, 0x17, // sample 2
        0x1e, 0xf3, 0x3c, // sample 3
        0x13, 0x3c, 0x14, // sample 4
    ];

    let samples = Samples::from_bytes(&header, &bytes).unwrap();

    assert_eq!(
        samples,
        Samples::BitDepth24(vec![
    	    0x00000000, // sample 1
    	    0x17240000, // sample 2
    	    0x3cf31e00, // sample 3
    	    0x143c1300, // sample 4
        ])
    )
}
