Lyrebird

Simple and powerful voice changer for Linux, written in GTK 3.

Why?

I decided to write this as a tool for myself, partly for fun and partly because I hate my own voice and since there was no decent Linux voice changers. The UI is based very loosely off of Clownfish for Windows, and is very simple and easy to use.

Features

• Built in effects for accurate male and female voices
• Ability to create and load custom presets
• Manual pitch scale for finer adjustment
• Creates its own temporay virtual input device
• A clean and easy to use GUI

Usage

1. Run install.sh to install dependencies and Lyrebird itself
2. Launch Lyrebird from your preferred application launcher (e.g. GNOME, Rofi)
3. Select a preset or set a custom pitch and flip the switch
4. Change the input device for the application to Lyrebird Virtual Input, this can be done in-app or using pavucontrol if you're not given the option
5. Ignore any applications that ask if you want to use "Lyrebird Output" (e.g. Discord), this is used internally and isn't necessary to use Lyrebird

Changing using pavucontrol

If an app doesn't support live input changing then it can be done with pavucontrol. Head to the "Recording" tab and change the input using the drop down next to the application name.

I can't?

For some apps on some distros (like Ubuntu) changing the input won't work. To fix this you need to create a file at ~/.alsoftrc and add the following contents:

drivers = alsa,pulse,core,oss

[pulse]
allow-moves=yes

Editing Presets

To edit the presets and add your own presets edit the file presets.toml. This file is in the TOML format, and the syntax is described below.

# name = Preset name, will be displayed in the GUI
# pitch_value = The pitch value of the preset, if you want to be able to adjust this use "scale"
# downsample_amount = The amount of downsampling to do, set as "none" if you don't want any
# override_pitch_slider = Whether the preset overrides the pitch slider or not

# Example preset, the [[presets]] is required for each preset
[[presets]]
name = "Woman"
pitch_value = "2.5"
downsample_amount = "none"
override_pitch_slider = true

Requirements

• python-gobject
• pavucontrol
• sox
• PulseAudio
