<p class="lead mt-4" style="text-align: justify;">Welcome to the Library of Underwater Acoustic Channels. This library contains impulse responses of communication channels recorded during different at-sea experiments, as well as the accompanying noise models. It also contains a user’s guide that explains how to download the channels, or how to directly apply the channels to a signal of your choice. Click on the entries below to explore the library.

Section pages:

- [Noise](/noises/): Site-specific ambient noise models accompanying each channel, covering colored Gaussian noise and, for the Red channel, impulsive alpha-stable noise.
- [Channels](/channels/): Eight color-labeled underwater acoustic channels recorded across sites worldwide, spanning shallow and deep water, short and long range, and fixed and mobile platforms.
- [Search Results](/search/): Search the Underwater Acoustic Channels library, noise models, and User's Guide.
- [User's Guide](/docs/): Instructions for downloading the channel library, replaying a signal through a channel, adding site-specific noise, and visualizing a decompressed channel.
