How to Classify Coding Artifacts? - #ARIJIT BISWAS# - Nov 21 7:52:00 2003
|
Dear multiple recipients of the list Speech-coding: I would like to know if there is any tutorial that teaches how to classify audio/speech coding artifacts (pre-echoes, aliasing artifacts, birdies, etc.). For example, if I listen to a piece of coded excerpt with some artifacts in it; how do I say the kind of artifacts it has, without knowing the details of how it was coded? I got hold of one CD from the AES, "Perceptual Audio Coders: What to listen for" but still I'm not confident. Is there any other suitable material? Or, does one gain it with years of listening experience? Regards, ~Arijit |
