ReplyGain anyone?

by **Post-logiq** » Fri Sep 06, 2013 6:02 pm

I started using ReplayGain at the time of MM3 because it was easy to get into it with automatic analyzis rather than using the early tools.
My initial hopes were those expected by RG, but also to physically level tracks for DJ sets based on those magic numbers.
I did all this with a mixed success, it's not accurate or it's my perception or my setup.
In some cases it helps, in others it doesn't, I can't be more precise about it.

In a few cases I experienced clipping on tracks that had strong correction values. I can't remember if they were + or - but >9 db.
Without doing thorough testing I guess it's pure coincidence if clipping did not happen on physically leveled tracks.

So... I don't mind keeping those magic numbers in my files as far I can activate or deactivate RG in any player.
From now on I will check physically leveled tracks if the initial magic numbers were high.

There are propositions for a ReplayGain 2 specification:

Going on the fact mm writes those tags when you anaylize song volume, (which i didnt know it did) then i'd have to say we all use it and i've not had trouble in using it,

I was wondering who many people are using replaygain, and if there are well known problems enabling it

As shown above, MM writes these tags.
Do you expect different tags or have you experienced any problems with it?

MM Analyze Volume is the same as ReplayGain. You don't need any additional tool.

As I've said, using semi-standard tags will allow replaygain usage across multiple players

MM Analyze Volume is the same as ReplayGain. You don't need any additional tool.

An example of MP3 tags written by MM:
TXXX="replaygain_album_gain 2.20 dB"
TXXX="replaygain_track_gain 2.20 dB"
TXXX="replaygain_track_peak 0.992767"

If everything is properly set and analysed, there are no drawbacks.
To avoid clipping and the resulting distortion, make sure you activate clipping prevention in the options and let all three volumes at 89 dB.

If you've got any MP3 from Amazon, you have to manually re-analyse it (that's a known MM issue but not seen as a bug).

Well only way i got to put it in my songs as far as i know is to add it in by playing in winamp or editing songs in audacity which i do both of, just what is making the sound louder on my songs is not really known other then the eq presets, because i've not played all songs in winamp and i've not edited all songs in audacity, so some have it in some dont, which are ones with it i cant tell all seem to sound loud with or wothout using mm's playback vol option.

To clarify, my original question was about replygain, mediamonkey or not. Was wondering if people over this community is using it succesfully

I don't know the technical details behind ReplayGain (thus don't know what MediaMonkey uses in Analyze Volume). However you can't save tags in MediaMonkey that aren't supported by MediaMonkey. So if MediaMonkey's Analyze Volume doesn't do what you need you can use any other program to perform it. As long as it is saved in the tags I presume that on sync from MediaMonkey to device that these tags will still be in the device and can be used by the device.

foobar2000 ReplayGain scanner
Format:
MP3: Values written to ID3v2 (default) or APEv2 tags. A separate function can be invoked to apply the tagged Track or Album Gain to the MP3 global gain fields (as MP3Gain does, but requiring tags first), and to rewrite the tags to account for the peak change and compensate for the difference from 89 dB. The 89 dB reference level for tags isn't configurable, but the reference level applied to the global gain fields is (it's under Preferences > Advanced > Tools > ReplayGain Scanner > Target MP3 alteration volume level).
Musepack: Values written to header.
(Ogg) Vorbis: Values written to Vorbis comment.
WavPack: Values written to APEv2 tags.
AAC: Values written to APEv2 tags.
MP4: Uses its own iTunes-compatible tagging system (though iTunes does not support ReplayGain).
FLAC: Values written to Vorbis comment.
APE: Values written to APEv2 tags.
Modules (MOD etc.): Optionally saved into APEv2 tags.

This way any compatible player will output volume accordingly

Oh android is being made now and mm is to work same on it as it does on desktop so just hang on till android mm is released, theres a bunch of us waiting for it too.

Replay gain is held in song properties by mm it just doesnt have field for it i think? Unless its on details tab. But i think mm is to use it, but might not on all systems for some reason. I know if i play songs in winamp that i know uses it, they are played at the replay gain vol. But i use the presets in mm because they are easier to use, in mm then in winamp. Winamp is easier to use replay gain as it just does it with out seting up anything ,mm is to do that also but the eq presets just give extra way to adjust the sound for the songs because they adjust the eq freq's aswell as the vol level.

On sync I use the Analyze Volume values for iOS devices (Sound Check) and Level Volume for any other devices as well as level volume for DLNA clients. This has worked very well for me (always use 89dB locally and up to 95dB for some portable devices).

At home I can use anaything to play music; oustide I use my phone (earphones, portable speakers, etc). I use a popular Android player tha supports the replygain tag. That's why I would like to parse the library and apply replygain accordingly

Actually I was thinking to run a script to update each track in the library so each one will hold a new tag (replygain) using tools (like foobar or similar)
