 |
|
So, I see in the latest news that both aacgain and mp3gain have been masked and slated for removal.
I use both of these in a cron job that updates my new podcast audio files.
So, given they are going away, what options do I have to replace them? Any?

Hmm. Had a quick look.
Having trouble figuring out how to convince sox to keep id3 tags in it's output.
Settled on | Code: | | rm soxed.mp3; time sox orig.mp3 --replay-gain track soxed.mp3; id3cp orig.mp3 soxed.mp3 |
as a test case.
Problem is, it appears that sox is re-encoding the audio file, whilst the equivalent | Code: | | rm gained.mp3; cp orig.mp3 gained.mp3; time mp3gain -r gained.mp3 |
(and aacgain) simply analyse the file and update the tags. This is indicated by the fact that sox takes over 30 seconds on my test file whilst mp3gain only takes 11.
The fact that I have to resort to using id3cp to copy the tags from the original file to the new file, when using sox, is a pain.
Of course, I am more than happy to be shown the error of my ways.

| They will be removed from portage tree but not from your computer. You can still take the ebuilds to your local overlay and/or unmask them in your system. |

As I understand it, mp3gain and aacgain do not affect in any way the digitised audio; they only add meta tags for ReplayGain. Does ffmpeg do the same, or, as I suspect, is it actually changing the digitised audio itself? One of the advantages of the ReplayGain approach is that it doesn't touch the digitised audio at all.

mp3gain and aacgain analyse the audio and then apply id3 tags indicating the volume adjustment required for playback.
They don't change the audio track at all, which, imho, is a good thing.

Agreed. Coincidentally I used aacgain yesterday on 100 assorted dance tracks for a party. Did a good job of normalizing the volume. ReplayGain is a nice concept. By the way, I've already copied the mp3gain and aacgain ebuilds to my local overlay and merged them from there now that those ebuilds are masked in the Portage main tree. Pity they are being removed, as they are important tools. I assume the fundamental problem is that there is currently no Gentoo developer to maintain the ebuilds.

Problem is ffmpeg re-encodes the audio, which I am not keen on. Prefer analysis of existing audio with addition of id3 tags.

| ffmpeg knows how to calculate and print replaygain (ffmpeg -c mp3float -i meow.mp3 -af replaygain -f null /dev/null) and it can definitely edit file metadata without re-encoding the audio. I'm not seeing any way to combine the two in one command though, sorry... |

That's a nice offer, and I think you should do that, although I think they should also remain in the main Portage tree even if you do. They are extremely useful. mp3gain does a great ReplayGain job for just mp3 audio files; aacgain does something similar for AAC (mp4/m4a/QuickTime) audio files in addition to mp3 files. So they are very much mainstream utilities in my opinion. The latest version of mp3gain was uploaded to the upstream package repository only a couple of months ago, so it's definitely not dead.

Tested this: media-sound/rgain - https://bitbucket.org/fk/rgain
For me it works. replaygain just added tags. And you get only one tool for Vorbis, Flac, WavPack, AAC, MP3. |

The mask messages are coming from portage, that compares the masked packages in profiles/package.mask with your installed packages.
News are not used to announce last-rites except for really big ones requiring migration (think Plasma-4). |

Thanks for the tip, but I noticed the following at that link:

If that is the case, then all we need is someone to step up and pick up maintenance of the package. |
