MUZECAST FORUM

Hello, I have a huge music collection but already have Replay Gain assigned to all of my tracks from WinAmp and Foobar. Why doesn't your scanning just ignore Replay Gain if it's already existing in the tracks? I can't get the scan to even come close to finishing because it's analyzing the tracks for Replay Gain, but they already have it built in.

I want to use Replay Gain while I'm playing through Muzecast, but I don't want the library scan to look at it as it's already there. Any way to do this?

Thanks for the quick reply, I think the option to read existing replay gain would be great and vastly speed up library scanning for many. Love the app, keep up the great work

In the next release of Muzecast Server I will add an option to use ReplayGain from tags and where it is missing, track will be scanned.

If ReplayGain tag information returns negative value, song will be analyzed for a peak volume and difference will be stored in Muzecast database as ReplayGain value instead of tag value.

If ReplayGain tag information returns positive value, song WILL NOT be analyzed and tag value will be stored in Muzecast database as ReplayGain value.

If ReplayGain tag is missing, song will be analyzed for peak volume and difference will be stored in Muzecast database as ReplayGain value

Next version of Muzecast Player will have an option to reset ReplayGain collected by Muzecast, so it will refresh it from tags.

Negative ReplayGain is treated as no replaygain, because it is inconsistent with other tracks, which might not have ReplayGain.

Muzecast scans the song if Tag is missing to find maximum peak volume and records it as ReplayGain.

For example, I have flac file for Deep Purple album where each song has ReaplyGain Tag as negative value -8dB for Track and -6dB for Album.
The rest of the songs I have do not have ReaplyGain tag stored. So Muzecast scans these songs. Let's say other songs become 0dB ReplayGain and played at 86dB normal volume. But because Deep Purple ReaplyGain was -8dB, when it is played in the mix, playback volume jumps to lower volume -8dB and song with 0dB gain plays loudly. That is why Muzecast ignores negative ReplayGain and treats it as 0dB without scanning a song to make sure all songs are played with equal volume.

Upcoming version of Muzecast Player will go even further and will use Album ReaplyGain when Album is played in Gapless Mode and Track ReplayGain when songs are shuffled or Mixed. If Muzecast will use negative ReplayGain, a lot of people will complain about low volume of playback.

But to satisfy each and every user, I might add an option to Muzecast Streaming Server to use only tag information for replay gain, and if Tag is missing, it will use 0db.

The way I'm reading this is that all tracks that have a negative dB level ReplayGain tag are not adjusted at all in Muzecast? If that is the case, this might explain the issue I'm having. I have songs from CDs made all the way back in the 80s in my library. With the modern loudness wars, CDs produced in the late 90's through today are being mixed much louder than older CDs. If I have a song that has a -2dB avg volume, and the next one is -12dB avg, then the volume will jump up substantially when that next track is played. The whole point of ReplayGain is to have every song play at a target loudness of 89dB. Right now, I'm experiencing these jumps in volume when shuffling through all of my music. It would be greatly appreciated to have a setting in Muzecast that follows the true ReplayGain spec, even if it only works for files that already have ReplayGain tags embedded. I'm well aware that all tracks would be played at a lower volume, but they'll also be at the same volume.

P.S. Thank you for all of your hard work in developing Muzecast. It has nearly every feature you could possibly ask for! I purchased the pro version several months ago, and I use it every time I get in my car.

That is excellent news. Thank you so much!

Just one more question. When implemented, will you be setting the ReplayGain target loudness at 89dB? I know in an earlier post you commented 86dB, but that is actually for the EBU R128 standard. Using a target loudness other than 89db could also cause issues with volume leveling, since by default ReplayGain scanners are configured to use 89dB SPL for reference.

In my case, at the moment, ReplayGain is only working with flac files. My mp3 files are all played at 0dB, despite them all having a ReplayGain value in their Id3v2 tag.

Sure, thanks as always for the quick reply. I'll post a couple of screenshots here to better show the issue and I'll mail you the file right away (to support@homedj.net). All my files are tagged using AIMP3 tag editor, if this can be useful to track the issue.
