Rockbox Audio Quality versus Original Firmware (RMAA comparison)
travishayes89:
i have not run such tests, but i have listened to music through rb on my ipod (before it got dunked) and also on the apple os, and noticed that the rb output sounded better on certain songs
ryran:
No way in hell I could abx those two (I gave it a try).
[In other news: in la futura, why not just use wavgain to get the samples to exactly the same volume?]

Febs, Saratoga,
EDIT: After checking all my sound settings, I realized that while I thought I had all sound effects off, it turns out that in fact I didn't. Upon a preliminary re-listen, I am finding a diminishing difference b/w the two OS'. OOPS! How embarrassing... Anyway, I will listen to your ABX samples, as soon as I learn how to ABX ???
Saratoga, thanks for the details; Febs, thanks for the tests - anywhere you know where I can find instructions on Foobar ABX'ing? I'll check the help file first I guess.
soap:
(Assuming Foobar 0.8.3) (Assuming you have the ABX component installed) (Believe it comes with the Special and Full builds)
1- Drop the two files into Foobar.
2- Select the two tracks, right click, and from the context menu select "ABX two tracks"
3- Foobar will do its thing preparing the files, then will present you with the ABX comparator screen. From here you can listen to the "A" sample, the "B" sample, the "X" sample, and the "Y" sample. The letters assigned to your two tracks will be randomly changed each trial, your task is to play the files however you want and tell if A=X or if A=Y.
The prefered methodology is to check the "Hide results" selection box, and to do at least 12 "trials" before exiting and saving your results as a text file.

Bravo Febs! Magnificent work on the samples and analyzing both firmware output!
This is a definite benchmark to shut off the mouths of some members here and MisticRiver.
As many of you have noticed, Rockbox is being under "attack" as having "inferior" sound quality compared to original firmware. (see the first golden quote in wiki: http://www.rockbox.org/twiki/bin/view/Main/GoldenQuotes)
For once again these persons are proven wrong. These tests show that Rockbox differences from original firmware are inaudible.
Again, thank you Febs, for providing the most failsafe way to compare sound quality and for the analysis that you made.
Let’s hope that this debate will end, and Rockbox will no longer be under the "inferior-sound-quality" myth.
PS: I will wait for omendelovitz's ABX test before continuing my "triumphology", who knows.... ::)
