Struct wavv::Header

pub struct Header {
    pub sample_rate: u32,
    pub num_channels: u16,
    pub bit_depth: u16,
}

Struct representing the header section of a .wav file

for more information see here

Fields

sample_rate: u32

sample rate, typical values are 44_100, 48_000 or 96_000

num_channels: u16

number of audio channels in the sample data, channels are interleaved

bit_depth: u16

bit depth for each sample, typical values are 16 or 24

Implementations

impl Header

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

Create new Header instance from a slice of bytes

Examples

use wavv::Header;

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);
}
