HPS Decode

A Rust library for parsing and decoding Super Smash Bros. Melee music files.

Quick Start

Decoding a stereo .hps file into audio and listening to it with rodio:

In your Cargo.toml:

[dependencies]
hps_decode = { version = "0.2.1", features = ["rodio-source"] }
rodio = { version = "0.17.3", default-features = false }

In your main.rs:

use hps_decode::Hps;
use rodio::{OutputStream, Sink};
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    // Decode an .hps file into PCM samples for playback
    let hps: Hps = std::fs::read("./respect-your-elders.hps")?.try_into()?;
    let audio = hps.decode()?;

    // Play the song with the rodio library
    let (_stream, stream_handle) = OutputStream::try_default()?;
    let sink = Sink::try_new(&stream_handle)?;

    sink.append(audio);
    sink.play();
    sink.sleep_until_end();

    Ok(())
}
