Riff Wave Reader

Reads riff-wave compliant files. Get header info and access to the underlying reader positioned on the data block.

Using RiffWaveReader

use anyhow::Error;

use std::fs::File;
use std::io::BufReader;

use riff_wave_reader::RiffWaveReader;

fn main() -> Result<(), Error> {
    let file = File::open("path/to/file.wav")?;

    let reader = BufReader::new(file);
    let mut reader = RiffWaveReader::new(reader)?;

    // Print header info
    reader.print_info();

    // Option 1, iterate over all data bytes
    let data = reader.data()?.collect::<Vec<u8>>();

    // Option 2, get the underlying reader, positioned at the start of the
    // data block
    let reader = reader.into_reader();

    // Do stuff with data / reader...

    Ok(())
}
