Turn your keyboard into a typewriter! 📇
daktilo-demo.mp4
daktilo ("typewriter" in Turkish, pronounced "duck-til-oh", derived from the Ancient Greek word δάκτυλος for "finger") is a small command-line program that plays typewriter sounds every time you press a key. It also offers the flexibility to customize keypress sounds to your liking. You can use the built-in sound presets to create an enjoyable typing experience, whether you're crafting emails or up to some prank on your boss.
✨ Inspiration: "Taking notes in class with my typewriter"
Now you can recreate this moment without the actual need for a physical typewriter!

Getting Started
Simply run daktilo for the classic typewriter effect.
There are also different presets available:
Preset Name
Description
default
the classic typewriter effect
basic
an alternative and more basic typewriter effect
musicbox
plays random notes like a music box
ducktilo
quack quack 🦆
drumkit
dum, tss, cha! 🥁
spark
high voltage high current typing experience ⚡
To list the presets:
daktilo --list-presets
To use a preset:
daktilo --preset musicbox
You can also use multiple presets at the same time:
# orchestra
daktilo -p default -p musicbox -p drumkit
To use a different output device:
daktilo --device pipewire
Also, you can use --list-devices to list the available output devices.
To variate the sounds and have a more realistic typewriter experience:
daktilo --variate-tempo 0.9,0.4 --variate-volume 0.1,0.5
Spoiler warning
There are easter eggs. If that is something you do not like you can disable them either via the config file option no_surprises = true or using the command-line flag:
daktilo --no-surprises

-V, --version Print version
Configuration
daktilo can be configured with a configuration file using the TOML format.
The path of the configuration file can be specified via --config argument or DAKTILO_CONFIG environment variable.
It can also be placed in one of the following global locations:
<config_dir> / daktilo.toml
<config_dir> / daktilo/daktilo.toml
<config_dir> / daktilo/config
<config_dir> depends on the platform as shown in the following table:
Platform
Value
Example
Linux
$XDG_CONFIG_HOME or $HOME/.config
/home/orhun/.config
macOS
$HOME/Library/Application Support
/Users/Orhun/Library/Application Support
Windows
{FOLDERID_RoamingAppData}
C:\Users\Orhun\AppData\Roaming
See daktilo.toml for the default configuration options.
You can also create the default configuration file in the current directory with --init flag:
daktilo --init
Adding custom presets
The configuration file consists of an array of sound_preset entries.
To define an array in TOML, you can create different sections as follows:
[[sound_preset]]
name = "custom"
key_config = []
[[sound_preset]]
name = "another_custom"
key_config = []
disabled_keys = []
variation = { volume: [0.1, 0.1], tempo: [0.05, 0.05] }
As shown above, sound_preset consists of 2 entries:
name: The name of the preset. It will be used in conjunction with --preset flag. e.g. --preset custom
key_config: An array of key press/release events for assigning audio files to the specified keys. It can also be used to control the volume etc.
disabled_keys: An array of keys that will not be used for playback.
variation: Variate the sound on each event for key_configs that do not specify variations*
Click for the list of available keys.
Alt, AltGr, Backspace, CapsLock, ControlLeft, ControlRight, Delete, DownArrow, End, Escape, F1, F10, F11, F12, F2, F3, F4, F5, F6, F7, F8, F9, Home, LeftArrow, MetaLeft, MetaRight, PageDown, PageUp, Return, RightArrow, ShiftLeft, ShiftRight, Space, Tab, UpArrow, PrintScreen, ScrollLock, Pause, NumLock, BackQuote, Num1, Num2, Num3, Num4, Num5, Num6, Num7, Num8, Num9, Num0, Minus, Equal, KeyQ, KeyW, KeyE, KeyR, KeyT, KeyY, KeyU, KeyI, KeyO, KeyP, LeftBracket, RightBracket, KeyA, KeyS, KeyD, KeyF, KeyG, KeyH, KeyJ, KeyK, KeyL, SemiColon, Quote, BackSlash, IntlBackslash, KeyZ, KeyX, KeyC, KeyV, KeyB, KeyN, KeyM, Comma, Dot, Slash, Insert, KpReturn, KpMinus, KpPlus, KpMultiply, KpDivide, Kp0, Kp1, Kp2, Kp3, Kp4, Kp5, Kp6, Kp7, Kp8, Kp9, KpDelete, Function, Unknown
As an example, here is how you can configure key_config:
key_config = [
{ event = "press", keys = "Return", files = [{ path = "ding.mp3", volume = 1.0 }] },
]
event: "press" or "release"
keys: A regular expression (regex) for matching the keys.
files: An array of files.
path: The absolute path of the file. If the file is embedded in the binary (i.e. if it is inside sounds/ directory) then it is the name of the file without full path.
volume: The volume of the sound. The value 1.0 is the "normal" volume (unfiltered input). Any value other than 1.0 will multiply each sample by this value.
variation: Variate the sound on each event*
If you have defined multiple files for a key event, you can also specify a strategy for how to play them:
key_config = [
{ event = "press", keys = ".*", files = [{ path = "1.mp3" }, { path = "2.mp3" }], strategy = "random" },
]
Currently supported strategies are:
strategy = "random": pick a random file from the list and play it.
strategy = "sequential": play the files sequentially.
Here is how you can combine everything together:
[[sound_preset]]
# Custom sound preset named "custom"
name = "custom"
# Key configurations for various events
key_config = [
# When a key starting with "Key" is pressed, play 1.mp3, 2.mp3, and 3.mp3 sequentially
{ event = "press", keys = "Key*", files = [
{ path = "1.mp3" },
{ path = "2.mp3" },
{ path = "3.mp3" },
], strategy = "sequential" },
# When a key starting with "Key" is released, play 4.mp3
{ event = "release", keys = "Key*", files = [
{ path = "4.mp3" },
] },
# When a key starting with "Num" is pressed, play num.mp3 at a very high volume (10.0)
{ event = "press", keys = "Num*", files = [
{ path = "num.mp3", volume = 10.0 },
] },
# When any key is pressed, play a random sound from cat.mp3, dog.mp3, or bird.mp3
{ event = "press", keys = ".*", files = [
{ path = "cat.mp3" },
{ path = "dog.mp3" },
{ path = "bird.mp3" },
], strategy = "random", variation = { volume: [0.1, 0.1], tempo: [0.05, 0.05] } },
]
# Disabled keys that won't trigger any sound events
disabled_keys = ["CapsLock", "NumLock"]
Sound Variation
To make the keyboard sounds more varied it is possible to variate both volume and playback speed (the later also varies the pitch).
Values are in percent, where the first value determines the maximum increase and the second the maximum decrease. The actual value is determined randomly on each keypress.
If command line arguments or environment variables are set configurations made in the presets are overridden.
Values need to be separated by a ",".
If only one value is supplied it is used for both increase and decrease
If a key_config is set the preset values are overridden.
The configuration on a preset applies to all key_config's that do not have any values set.

MacOS permissions
On MacOS, you need to give some permissions to the terminal where you run daktilo.
The first time you run daktilo, you will probably see this popup:
If you see it, click on "Open System Settings", otherwise open "System Settings" manually and go to "Privacy and Security".
From here, enable "Input Monitoring" for your terminal application:
