Audacity
Audacity is a NLE made specifically for audio production. It was very commonly used early in the tennis scene for more precise audio edits, as video editors at the time were not capable of sophisticated audio functionality (especially with techniques like stuttering.
Nowadays, Audacity is mainly used for Databending. Modern versions of Audacity have seen some regression in recent years due to its acquisition by Muse Group, however older versions and forks still work just fine.
