## Motivation ✨

- [Bash One Liner - Compose Music From Entropy in /dev/urandom](https://web.archive.org/web/20230122184930/https://blog.robertelder.org/bash-one-liner-compose-music/)

  - ['Music' from /dev/urandom](https://news.ycombinator.com/item?id=11238247)

## Installation 🤖

### Build from source

#### Prerequisites

- [Zig](https://ziglang.org/download/) (`0.10.1`)

#### Instructions

1. Clone the repository.

```sh

git clone https://github.com/orhun/linuxwave && cd linuxwave/

```

2. Update git submodules.

```sh

git submodule update --init --recursive

```

3. Build.

```sh

zig build -Drelease-safe

```

Binary will be located at `zig-out/bin/linuxwave`. You can also run the binary directly via `zig build run`.

If you want to use `linuxwave` in your Zig project as a package, the API documentation is available [here](https://orhun.dev/linuxwave/docs).

### Binary releases

See the available binaries for different targets from the [releases page](https://github.com/orhun/linuxwave/releases). They are automated via [Continuous Deployment](.github/workflows/cd.yml) workflow.

Release tarballs are signed with the following PGP key: [0xC0701E98290D90B8](https://keyserver.ubuntu.com/pks/lookup?search=0xC0701E98290D90B8&op=vindex)

### Arch Linux

`linuxwave` can be installed from the [community repository](https://archlinux.org/packages/community/x86_64/linuxwave/) using [pacman](https://wiki.archlinux.org/title/Pacman):

```sh

pacman -S linuxwave

```

### Void Linux

`linuxwave` can be installed from official Void Linux package repository:

```sh

xbps-install linuxwave

```

### Docker

#### Images

Docker builds are [automated](./.github/workflows/docker.yml) and images are available in the following registries:

- [Docker Hub](https://hub.docker.com/r/orhunp/linuxwave)

- [GitHub Container Registry](https://github.com/orhun/linuxwave/pkgs/container/linuxwave)

#### Usage

The following command can be used to generate `output.wav` in the current working directory:

```sh

docker run --rm -v "$(pwd)":/app "orhunp/linuxwave:${TAG:-latest}"

```

#### Building

Custom Docker images can be built from the [Dockerfile](./Dockerfile):

```sh

docker build -t linuxwave .

```

## Examples 🎵

**Default**: Read random data from `/dev/urandom` to generate a 20-second music composition in the A4 scale and save it to `output.wav`:

```sh

linuxwave

```

Or play it directly with [mpv](https://mpv.io/) without saving:

```sh

linuxwave -o - | mpv -

```

To use the A minor blues scale:

```sh

linuxwave -s 0,3,5,6,7,10 -n 220 -o blues.wav

```

Read from an arbitrary file and turn it into a 10-second music composition in the C major scale:

```sh

linuxwave -i build.zig -n 261.63 -d 10 -o music.wav

```

Read from stdin via giving `-` as input:

```sh

cat README.md | linuxwave -i -

```

Write to stdout via giving `-` as output:

```

linuxwave -o - > output.wav

```

## Presets 🎹

Generate a **calming music** with a sample rate of 2000 Hz and a 32-bit little-endian signed integer format:

```sh

linuxwave -r 2000 -f S32_LE -o calm.wav

```

Generate a **chiptune music** with a sample rate of 44100 Hz, stereo (2-channel) output and 8-bit unsigned integer format:

```sh

linuxwave -r 44100 -f U8 -c 2 -o chiptune.wav

```

Generate a **boss stage music** with the volume of 65:

```sh

linuxwave -s 0,7,1 -n 60 -v 65 -o boss.wav

```

Generate a **spooky low-fidelity music** with a sample rate of 1000 Hz, 4-channel output:

```sh

linuxwave -s 0,1,5,3 -n 100 -r 1000 -v 55 -c 4 -o spooky_manor.wav

```

Feel free to [submit a pull request](CONTRIBUTING.md) to show off your preset here!

```

### `scale`

Sets the musical scale for the output. It takes a list of [semitones](https://en.wikipedia.org/wiki/Semitone) separated by commas as its argument.

The default value is `0,2,3,5,7,8,10,12`, which represents a major scale starting from C.

Here are other examples:

- A natural minor scale: `0,2,3,5,7,8,10`

- A pentatonic scale starting from G: `7,9,10,12,14`

- A blues scale starting from D: `2,3,4,6,7,10`

- An octatonic scale starting from F#: `6,7,9,10,12,13,15,16`

- Ryukyuan (Okinawa) Japanese scale: `4,5,7,11`

### `note`

The `note` option sets the frequency of the note played. It takes a frequency in Hz as its argument.

The default value is `440`, which represents A4. You can see the frequencies of musical notes [here](https://pages.mtu.edu/~suits/notefreqs.html).

Other examples would be:

- A3 (220 Hz)

- C4 (261.63 Hz)

- G4 (392 Hz)

- A4 (440 Hz) (default)

- E5 (659.26 Hz)

### `rate`

Sets the sample rate for the output in Hertz (Hz).

The default value is `24000`.

### `channels`

Sets the number of audio channels in the output file. It takes an integer as its argument, representing the number of audio channels to generate. The default value is `1`, indicating mono audio.

For stereo audio, set the value to `2`. For multi-channel audio, specify the desired number of channels.

Note that the more audio channels you use, the larger the resulting file size will be.

### `format`

Sets the sample format for the output file. It takes a string representation of the format as its argument.

The default value is `S16_LE`, which represents 16-bit little-endian signed integer.

Possible values are:

- `U8`: Unsigned 8-bit.

- `S16_LE`: Signed 16-bit little-endian.

- `S24_LE`: Signed 24-bit little-endian.

- `S32_LE`: Signed 32-bit little-endian.

### `volume`

Sets the volume of the output file as a percentage from 0 to 100.

The default value is `50`.

### `duration`

Sets the duration of the output file in seconds. It takes a float as its argument.

The default value is `20` seconds.

### `input`

Sets the input file for the music generation. It takes a filename as its argument.

The default value is `/dev/urandom`, which generates random data.

You can provide _any_ type of file for this argument and it will generate music based on the contents of that file.

### `output`

Sets the output file. It takes a filename as its argument.

The default value is `output.wav`.
