Hello,

I use Replaygain for all my CDs -> lossless with foobar.

I wonder if it's better to burn a cd with Replaygain or not (foobar can do that) ?
Same thing for the "Dither" option.

The copied CD is for car audio and Hi-Fi.

Thanks.

Of course it makes sense burning the disc using Replay Gain, no matter whether it's used in a car stereo or in your Hi-Fi. In both cases you aren't forced to manually adjust the volume all the time.

Dithering is only interesting if you decide burning 24 bit sources, simply to prevent the appearance of audible digital noise on your final 16 bit audio CD. Keep this function disabled as long as you're working with 16 bit files, it won't have any useful effect in such a case.

Well, I think it depends a little on what you want. I would not burn an audio CD with ReplayGain if I meant to create a copy of an original CD; I would want it identical to the original CD.

One the other hand, if I was burning a "variety" CD with tracks from different CDs then I would certainly use ReplayGain so the volume wouldn't change from track to track. If you have a bunch of CDs in a CD changer then you might want to use ReplayGain for them too so the volume is consistent.

If you use ReplayGain then it's probably recommended to use dither also because you are essentially converting back to 16-bit after the gain operation. But the odds that you'd hear the difference are pretty close to zero.
