Speed benchmark of audio encoders

This page shows results of a speed-benchmark test of audio encoders. Among other important factors for choosing an encoder such as sound quality (for lossy codec), compression ratio (for lossless codec), and usability (for listening to music with a hardware player), this benchmark result provides another information for making a decision. The benchmark result also shows how effectively an optimization build and enhancement for an audio codec works.
