Hi all, I'm a long time reader, first time poster. We are developing a somewhat auditory-system based compression scheme for speech and audio and, in addition to listening to the decompressed audio (naturally), we would like to computationally evaluate the faithfulness of the compressed version to the original. Aside from SNR, are there any standard/community accepted ways of evaluating audio that has undergone lossy compression? Thanks in advance, Rob
