Will Do This Later, But Some Comments.....

I think the biggest reason people "fail" CD-vs-MP3 listening tests is that the conduit for running such tests often does not maintain the signal integrity, which mostly impacts the sound of uncompressed signals. Another problem is that a lot of purportedly "uncompressed" data that is not on original media has been compromised.

The only way to run a test like this properly is to do an ABX/DBT with the uncompromised uncompressed signal vs. the encoded/decoded compressed signal, burned onto CD-R, on a playback system that does not compromise the integrity of the Redbook signal. (About 90 percent of CD playback systems *do* compromise the Redbook signal, IMHO.)

I plan on doing this with non-compressed vs. FLAC or Monkeys Audio. Burning an "ABX CD". Using dBPoweramp as the ripper, utilizing different encoding/decoding within the ripper. (The non-compressed tracks will be done with no compression in data transfer.) I think the sound is degraded not only with classic MP3 compression, but so-called "lossless" compression as well. And I think it can be proven with a DBT, under tightly-controlled conditions.

Once I finish testing, I will make this "ABX CD" available to fellow inmates, simply to allow independent verification of the data. The information given should result in verification via comparison utilities like EAC.
