Data to sound

A simple crate to convert data to sound, and sound to data. The sound file format is wave (.wav). You can use it as a library or as a command line tool. (dependency-free)

Minimum supported Rust version

The minimum supported Rust version is 1.59.0.

Note

The sound frequency is 202860Hz (202.86kHz), and the sound is mono. The sound is encoded in 16 bits.

Disadvantages

• The wave file size limit is 4GB, so you can't store more than 4GB of data in a single file.

Advantages

• The sound file is a standard .wav file, so you can play it with any audio player.
• The sound file will be the same size as the data file.

Usage

There are two ways to use this crate. As a library, or as a command line tool. The library is the core of the tool, so you can use the library to create your own tool.

Library

Add this to your Cargo.toml:

[dependencies]
data2sound = "0.2.0"

See the documentation for more information about the library.

Command line Interface

Install the tool with cargo:

cargo install data2sound

Run the tool with:

data2sound --help

And to convert a file to sound:

data2sound encode input_file output_file.wav

And to convert a sound file to data:

data2sound decode input_file.wav output_file

Use cases

This crate can be used to store data in a sound file, and to retrieve the data from the sound file. This can be useful for storing data in a sound file.
