# Third-party licences

Front Row Audio Enhancer includes the work below. Each component's licence
requires its notice to be reproduced in software that ships it, which is what
this file is for. The same notices ship inside the extension package, in
THIRD-PARTY-LICENSES.md, fonts/OFL.txt and vendor/upstream/. This is the
public copy, so it can be read before installing rather than only after.

## RNNoise

The neural network that performs the noise suppression. It ships inside the
extension and runs on your own machine.

## Instrument Sans and Instrument Serif

The control panel's typefaces. Copyright 2022 The Instrument Sans Project
Authors and The Instrument Serif Project Authors, used under the SIL Open Font
Licence 1.1. Both fonts are bundled inside the extension rather than loaded
from a font server, so the extension never has to reach one. The full licence
text ships with the extension as fonts/OFL.txt.
