Recording in WavPack (vs Wav)

(1/1)

mlind:
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!!  :D

Davide-NYC:
Were you using the remote on the iriver during the recording? (The remote's LCD is known to induce noise while recording from analog sources and listening back to anything)

If not then maybe the main LCD induces a tiny of noise as well? (just a thought)

mlind:
No remote.
Recording from digital.
The noise was clearly related to the intensity of the (piano) music.
