## 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`.
