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...
