I did a quick test. I compared Sony's Atrac3plus to other formats at 64 kbps. Only one sample used. All files were normalized before listening. The original sample used:http://www.kolumbus.fi/hahne/atrac3plus/sample.flac -Genre: Heavy Metal -Artist: Nightwish -Track: Nemo Used encoders: Lame 3.97 a 3 --preset 128 as anchor Lame 3.97 a 3 --preset 64 Sonic Stage 2.1 for Atrac3plus 64 kbps (+ Total Recorder for wave conversion) WMA std 9 (dBpowerAMP) 64 kbps Vorbis q0 (oggdropXPd 1.7.11 - libvorbis 1.1-RC1 compiled Jul 8 2006) The results:ABC/HR Version 1.0, 6 May 2004 Testname: atrac3plus vs others 1R = lame128.wav 2R = vorbisq0.wav 3L = wma64.wav 4R = lame64.wav 5R = a3p64.wav --------------------------------------- General Comments: --------------------------------------- 1R File: lame128.wav 1R Rating: 4.0 1R Comment: perceptible, but not annoying --------------------------------------- 2R File: vorbisq0.wav 2R Rating: 2.0 2R Comment: weird stereo problems --------------------------------------- 3L File: wma64.wav 3L Rating: 2.2 3L Comment: metallic sound --------------------------------------- 4R File: lame64.wav 4R Rating: 1.0 4R Comment: --------------------------------------- 5R File: a3p64.wav 5R Rating: 3.0 5R Comment: --------------------------------------- Conclusion: Atrac3plus is surprisingly good with this sample @ 62 kbps. Don't know about other samples though. Edit: ABX results removed because they might make you misinterprete my main idea.
