Fedora / CentOS

  1. Install the local RPM file, changing the name of the file to the one downloaded:
sudo yum localinstall lyrebird-1.2.0-3-fedora.fc38.noarch.rpm

Lyrebird Usage

  1. Select a preset or set a custom pitch and flip the switch
  2. 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
  3. 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

Common Issues

ModuleNotFoundError: No module named 'lyrebird.mainwindow'

Firstly make sure you've ran the most up-to-date install.sh script. If the issue still persists then this is probably a permissions issue, running sudo chmod -R 755 /usr/local/share/lyrebird /etc/lyrebird should fix this.

If the issue still sticks around then please open a GitHub issue and include the output of id -u; which lyrebird; sudo ls -lAn /usr/local/share/lyrebird; sudo ls -lAn ~/.local/share/lyrebird.

Editing Presets

Custom presets are stored in ~/.config/lyrebird/presets.toml. To edit and add your own presets edit the file presets.toml, this file is in the TOML format and the syntax is described below.

# Effect presets are defined in presets.toml
# The following parameters are available for presets

# name: Preset name, will be displayed in the GUI
# pitch_value: The pitch value of the preset, float value between -10.0 to 10.0. Omit if pitch value should not be affected from slider value.
# downsample_amount Downsample by an integer factor.
# volume_boost: Amount in dB to boost the audio. Can be negative to make the audio quieter.

# e.g.
# [[presets]]
# name = "Bad Mic"
# pitch_scale = -1.5
# downsample_amount = 8
# volume_boost = 8
