Does anyone use the DSP Effect (ReplayGain) when ripping CD's?

Yes, I do.

I would assume most people do. It is just a tag and doesn't alter audio. Some players can use the info. I add album and track level info to my tags when ripping.

Re: DSP Effect (ReplayGain)

Can tags be add or removed after the music has already been ripped?

You can remove any tags you want. You can also run a conversion just to add tags, including ReplayGain.

Oh wow, thanks! That's great to know.

Question about this. I usually work with lossless files, so I'm simply converting a lossless file to a lossless file and adding the RG tags. No problems. But...

What about if I were working with a lossy file, say for example an iTunes m4a track at 256k. If I wanted to add RG tags what would I convert it to without loosing any further information from the file. Would I have to convert it to a lossless file? If I converted it to an m4a track at 256k would that be identical to the original file or would it loose information in the conversion essentially becoming more "lossy"?

Re: DSP Effect (ReplayGain)

In codec central are utility codecs for ReplayGain, which just write the tags, you convert the file(s) to replaygain and the tags are written.

Re: DSP Effect (ReplayGain)

I would be careful creating replaygain tags for the following reasons:

- If you do this while ripping, if any tracks need to be re-ripped, then your album replaygain tags will not be accurate and you'll need to redo the tags for all of the tracks on the album
- Any lossless to lossess conversion will have the same replaygain calculation values, but any lossy file will have peaks different than other lossy or lossless formats, so you should redo replaygain peak tags for any conversion involving lossy codecs. Peak tags are used for clipping prevention in players like Foobar2000.

I already ripped all my CD's to FLAC with replaygain. Are you saying I should now remove all the replaygain tags and re-add them?

no. I don't even understand twit's concern. If you have to rerip one or more tracks on an album, it is correct that you should then immediately redo the RG tags (so the album value is correct). Easy enough to do right then. But for a normal rip you are good to go. And in terms of converting from say, FLAC to mp3, I use a RG DSP for that as well and there is a dbpa setting that tells it to redo the RG tags in the mp3 files rather than inheriting the FLAC RG tags.

Good to know.

So which is it - you don't agree with my recommendations, or you don't understand my concern? The OP stated he had ripped "all" of his CDs. Did you rip all of your CD's without any need for a redo even one one track even once? I can't say that accurately. I would be stunned if anyone ripped hundreds of CDs without a single issue. No need for dBpoweramp Ripper if that's the case.

To be clear: if you had to rerip even a single track on any CD, and when you reripped you only reripped the problem tracks, then you need to dump those album replaygain tags and recreate your album Replaygain tags for all tracks on that album. Album Replaygain tags can only accurately be created if you run the process on all tracks of an album at once. If, when any track on any CD had any problems, you reripped all tracks on the CD in the same run and continued to do so until all tracks ripped to your satisfaction in a single rip event, then you don't need to rerun album replaygain tags. Garym, if you disagreee with this point, then there is not much more to chat about.

If you can't remember which tracks you had to rerip or which albums you had to rerip at least one track and if you just reripped the problem tracks, then I recommend that you recreate all album replaygain tags for all albums. It won't take very long (you can run it overnight), and if you are concerned enough about your tags to consider replaygain tags, it'll be worth it to get them right.

It was about 300-400 CD's that I ripped. There were 4 or 5 CD's with tracks that had error's on them because of scratches, about 10 tracks in total. If a track had an error, I cleaned the CD and re-ripped the entire album. Also, I also added the DSP tag 'Move Destination File On Error'.

I agree with this point, and said the same exact thing (although not as clearly as you did above) in my reply. I thought you were saying that one should never add RG tags when ripping. That's what I disagreed with. I've ripped thousands of CDs and am meticulous about my tags, etc. I add RG tags on ripping (use of the DSP as part of ripping). 8 out of 10 times (maybe more), all is good with original rip. But if not, upon reripping certain tracks to get to all secure (even if requiring a different computer/drive), I then immediately redo the Album RG tags for all the tracks on the album. There is no "remembering" what happened as I take care of this immediately. As you say, and I agree, one must do this for ALL the tracks on the album at the same time.

So I think we are in agreement, unless you are saying you should never add RG tags at the time of ripping. Here I would disagree because most of the time, the original ripping is correct and the tracks are secure.
