DASP-RS: Digital Audio Signal Processing in Rust

DASP-RS provides a collection of tools and utilities for audio signal processing, analysis, and generation. It includes functionality for handling audio input/output, performing signal transformations, generating synthetic signals, extracting audio features, working with magnitude spectra, and pitch-related operations. The library is designed to be modular and extensible, leveraging Rust’s performance and safety features.

Key Features

• Audio I/O: Loading and saving audio files with flexible options.
• Signal Processing: Time-frequency transforms (e.g., STFT, CQT) and filtering.
• Signal Generation: Creating synthetic waveforms and noise.
• Feature Extraction: Computing audio features like tempo, pitch, and spectral properties.
• Magnitude Operations: Manipulating and analyzing magnitude spectra.
• Pitch Utilities: Converting between frequency, MIDI, and musical notations.
• Utilities: General-purpose functions for audio analysis and conversion.

Usage

To use this library, add it to your Cargo.toml and import the desired modules:

[dependencies]
dasp-rs = "0.2.0"

// Option 1: Use prelude for convenience
use dasp_rs::prelude::*;
 
let audio = Decoder::from("example.wav")
    .sample_rate(22050)
    .mono()
    .load()?;
 
let duration = get_duration(&audio);
println!("Duration: {} seconds", duration);

// Option 2: Explicit imports for clarity
use dasp_rs::{types::AudioData, io::{Decoder, export}, util::get_duration};
 
let audio = Decoder::from("example.wav")
    .sample_rate(22050)
    .mono()
    .load()?;
 
let duration = get_duration(&audio);
println!("Duration: {} seconds", duration);

API Structure

The API is organized by concern for clarity and discoverability:

• prelude - Convenient imports for common use cases
• types - Core audio data types (AudioData, AudioError)
• io - Audio input/output operations
• proc - Signal processing algorithms
• feat - Audio feature extraction
• util - Utility functions
• pitch - Pitch detection and conversion
• mag - Magnitude spectrum operations
• generate - Signal generation
