![]() It also puts the Peak and Gain values listed above into "RVA2" fields(s). ![]() My description applies when you use mp3gain's "/s i" parameter. I think the only way I could use it would be to allow it to write APE tags and then use some other app to read the RG fields and transfer the data to the ID3v2.3 tag, then delete the APE tag. These are somewhat of a standard.īut when using '/s i' to write ID3v2 tags, mp3gain changes the ID3v2.3 tag to an ID3v2.4 tag and writes only these fields: It's the REPLAYGAIN fields that I'm interested in, as I use Mp3s only on my portable players running Rockbox and those are the fields that it recognizes. When using '/s a' (the default) to write APE tags, mp3gain writes the following fields and leaves the ID3v2.3 tag intact: Mind you, I'm only interested in having the files tagged with REPLAYGAIN data, not actually altering the data to effect volume normalization. I'm guessing that is the new standard, which will make it easier for players to decode. Mp3gain uses id3v2.3 TXXX fields to store it's proprietary undo type information, but stores Track_Gain and Album_Gain in a ID3v2.4 field called RVA2. surely due to the inserted tag-field "MP3GAIN_MINMAX". The MD5AUDIO hash seems not to be touched when applying "mp3gain.exe /k /s i" against the mp3 file.īut the CRC32 hash and the overall MD5 hash has been changed. I did a quick test using mp3gain.exe version 1.5.2 with one mp3 file. and doing so I have instantly all Replay Gain options at hand, which are provided by foobar, since version 1.1.6 with precise quality, following the EBU R 128 standard for loudness normalisation. I use Mp3tag tools to apply non destructive Replay Gain this way. and I always do not recommend MP3Gain, because it works with the mp3 files on a destructive base by modifying the mp3 data stream, that means the MD5AUDIO checksum will be changed. for some people it looks rather complicated. I respect your achievements on connecting the MP3Gain commandline tool with Mp3tag.īut. ![]() I'd be interested in help with improvements. I use MP3Tag for all tagging, so I wanted the capability to adjust playback volume from within MP3Tag. ![]() Suppressing the dialog box that confirms that you want to open the export file. I'd be interested in help with improvements, including, but not limited to!:Īdding ReplayGain, as a context menu item (like Export, Converter, Tools, etc.), and having these 7 functions and/or others available in the submenu. If I wanted to bump up the volume a little bit for a particular track, I put "/r /m 3" in the %encodersettings% field. Instead of explicitly containing the "/a" (album) or "/r" (track) parameter, RGX uses %encodersettings% to add the "/a" or "/r" into the export file. %encodersettings%) with mp3gain.exe parameters. I tag each track (take a field that you don't use, e.g. For example, I have one (RGX) that combines RG4 and RG5. It certainly is possible to add more functionality with more complex Export Configurations. $loop(%_filename_ext%)c:\Utils\MP3Gain\mp3gain /s i /s d "%_folderpath%%_filename_ext%" $loop(%_filename_ext%)c:\Utils\MP3Gain\mp3gain /s i /u "%_folderpath%%_filename_ext%" $loop(%_filename_ext%)c:\Utils\MP3Gain\mp3gain /s i /k /a "%_folderpath%%_filename_ext%" RG5 - Apply Album RG to selected MP3 files $loop(%_filename_ext%)c:\Utils\MP3Gain\mp3gain /s i /k /r "%_folderpath%%_filename_ext%" RG4 - Apply Track RG to selected MP3 files: $loop(%_folderpath%)c:\Utils\MP3Gain\mp3gain /s i %_folderpath%*.mp3"$loop(%_filename_ext%%)$loopend() RG3 - Analyze selection as albums (by folder): RG2 - Analyze selection as a single album:Ĭ:\Utils\MP3Gain\mp3gain /s i $loop(%_filename_ext%)"%_folderpath%%_filename_ext%" $loopend() $loop(%_filename_ext%)c:\Utils\MP3Gain\mp3gain /s i "%_folderpath%%_filename_ext%" RG1 - Analyze selection as individual tracks: I used MP3Tag's Export tool to build 7 Export Configurations (similar to the way ReplayGain is integrated into Foobar2000): It supports ID3 tags (Version 1.5.2), and It uses ReplayGain (IMO, a better implementation than peak leveling, e.g. I decided to use mp3gain.exe for this because: Fixing this issue is primarily a tagging exercise. I frequently listen to shuffled music and find the volume difference between songs to be somewhat annoying.
