SEA is a low-complexity, lossy audio codec designed for embedded devices, inspired by the awesome QOA codec. Like QOA, SEA utilizes the Least Mean Squares Filter (LMS) algorithm, but it introduces variable bitrate (VBR) support and features slightly modified quantization tables. The reference implementation is written in Rust, and a compact ~250-line decoder written in C is also available for demonstration purposes.
