Beside my report of strangeness [after getting a "disk full" while recording],
I want to give a very positive report about recording experiences from yesterday.
I often record to WavPack, but I wasn't really sure about just HOW good it was compared to uncompressed Wav.
Yesterday I recorded a classical concert, and as main device relied on a HHB CD-recorder.
The studio I borrowed (at the concert hall) is equipped with a seperate A/D converter [Prism "Dream" AD-1] that feeds the CD-R via AES/EBU.
On the back of the AD-1 I also found an optical SPDIF output that I fed to my iRiver H120 recording to WavPack. So two devices recorded the digital outputs of the same ADC.
Today I took both recordings and put them side by side in ProTools and aligned them sample accurate.
Then I inverted phase (polarity) for one of the tracks, and bang! ...no, not "bang" at all... :-)
Complete silence!
The tracks from the CD-R and RockBox (WavPack) was really 100% identical!
To many of you this might not be any news at all.
But to me it was very reassuring about:
1. Using WavPack for important material.
2. The file splitting in Rockbox
(I made new tracks in both RockBox and on the CD-R, and that didn't change the good performance)
3. Recording via optical in Rockbox
ROCK SOLID! (as long as your HD space doesn't run out...)
I actually had a reason to distrust some part of the rockbox recording:
While recording I listened through the headphones output on both the CD-R and the iRiver, and on the iRiver i heard some very faint ticks that implied some digital artifacts - and found nothing like that on the CD-R. (The ticks came more often and was more audible when the music was louder)
Afterwards I haven't found the ticks on the recording, so I guess that it only existed on the "monitor" side of my iRiver.
Conclusion:
I'm VERY HAPPY WITH ROCKBOX!! Â
