Blind listening tests for audio compression
Posted: Tue Jan 11, 2011 10:17 am
Hi guys,
I'm sure all of us have seen their share of listening tests for various lossy audio compressors. I'd like to collect some results drawn from a more specific audience, namely us music folks... particularly since I want to know whether my ears are completely horrible if I can't hear any difference.
I have set up a small page that has a snippet from a random song compressed to FLAC three times: once directly, once after pulling it through an MP3 encoder, once after pulling it through an Ogg Vorbis encoder.
So, if you ever wanted to know whether you can actually hear the difference between lossless and lossy, or if you want to help collect data, head on over to: http://jk.gs/abctest/ (or http://jk.gs/abctest/abtest.php for comparing only two files).
Feel free to participate as many times as you like (the order of the files is randomized each time), but please only submit serious guesses. Also feel free to report your results here.
So far I have not managed to correctly guess all files, and certainly not several times in a row.
