I nominate nnnoiseless, a port of Xiph's RNNoise (written in C) to safe Rust. The release was accompanied by a blog post by the author, where they explain some of the porting process as well as subsequent performance optimizations that lead to the port overtaking the original C version in their benchmark. There has been a discussion on the subreddit.
