cdda frames correction

[ledestin]

thanks for the hint.

yes, i still have my original file and will try what you suggested.

also, i tried what gale had proposed, but could not get it working in audacity with the existing files?

We did tell you it was fiddly to do it that way. But you need CDDA frames set in Selection Toolbar and Snap To on even if you rejoin the files then Export Multiple by labels.

I think you're making hard work of a simple task. I've made many gapless CDs that play perfectly continuously from one track to the next, and I've never bothered splitting on CDA boundaries, I just let the CD authoring application handle it by selecting the "no gap" option. Some more primitive CD authoring apps may require that the tracks end on CDA boundaries, but most modern CD authoring applications can do gapless CDs whether the tracks end on CDA boundaries or not.

I agree with Steve you should probably just try it without making new WAV's split on CDDA boundaries.

But just for completeness, the double-click to select all disregards Snap To units. If after selecting all you zoom in at the end of the track ( CTRL + 1 then CTRL + } ) then hold SHIFT and click close to the end of the track, the right selection edge will contract or expand to a frame boundary. It is fiddly if you wanted it to expand because you would have to generate silence after the end of the track, which is probably not what you want. You can choose "Nearest" or "Prior" Snap To in current Audacity, but If you only have a checkbox for Snap To, you cannot choose and the behaviour varies between Audacity version.

@gale: ok, i will retry.


@steve: and so did i, and in some cases wondered about a little gap (but only from cd), even though i splitted them 'correctly' with audacity..

lately i used a different tool for burning, namely cdrecord. now comes the interresting part: i can not burn my waves with it, using -sao and -nopad.... guess why
i need to set -pad in order to let cdrecord do the adjustment, the result is once more not gapless..

now you know why i am interrested in batch adjustment.

may i ask what burning tool you use, as it seems to give better results?

Last time I made any gapless CDs was with K3B (I use Linux).

Previously (years ago) I have used both Nero and CDBurnerXP to make gapless CDs. I stopped using Nero because it became too bloated, and I stopped using CDBurnerXP because I stopped using Windows. Probably more helpful to get suggestions from a regular user of Windows.

[ledestin]

so k3b generated discs really never gave you any noticable gap on track change (even with nonconform cdda frames)?

that is very interresting. maybe i should give it a try, but basically it is just another frontend to cdrtools as well. i wonder which occult option it adds for burning

@gale: finally i was able to correct the waves with audacity & cdrecord (simulate) does not complain anymore, thank you.

but i still need to listen to a burned disc to be sure about gaps.

just a quick question: is it possible to adjust the beginning of a track (not the end), as well?

So you are burning on Linux now?

The beginning of a track (time zero) should by definition be at at the start of a CDDA frame.

yep, i am on linux... (wrong section, i know... but this subject is not os specific anyways)

so i listened to the cd and the result sounds better with audacity corrected tracks this time.

i am really curious to know, why cdrecord's padded tracks are not on par? shouldnt the result be somewhat identical?
