MediaMonkey supports Replay Gain analysis and playback (per Track and per Album via 'Analyze Volume' and 'Level Playback Volume'). This is an excellent approach for PC-based players, but is limited because many portable devices do not support Replay Gain tags, and thus when tracks are synced to a device, the volume will vary. Then, during playback, the Album or Track gain tag is read and the player adjusts the volume up or down accordingly (Album gain is preferable for playing an entire Album and preserving the inter-track volume variances encoded in the original album, while Track gain is preferred for playing a playlist of tracks from various sources). Then after all tracks on an Album have been analyzed, a single coefficient is saved for all tracks on the album (Album gain). Replay Gain (achieved by using “Volume Analysis”): With Media Monkey first track volumes are analyzed and the resulting coefficient is saved to the track's tag (Track gain). In order to level the sound from different MP3 songs that playback at different loudness, the songs can be either 1) permanently changed (MP3 Gain) or 2) temporarily changed (Replay Gain). MediaMonkey supports both ID3v1 and ID3v2 (version ID3v2.3 and ID3v2.4). The ID3 Tags have evolved starting with ID3v1 and as they evolved the new Tags began allowing more information to be stored into the newer version Tags. MP3 digital music also allow Track information to be embedded using “ID3 Tags”. This is what I have read (if I have read it correctly): but it also had a variance from -2 to +2. expected that to also be zero since it was already already hardcoded to 89. Then I took the 20 files that had been "Level Track Volume" and did an "Analyze volume". After a "Level Track Volume" shouldn't the numbers go to zero. Instead the Album volume varied from -2.1 to +.6 and the Track Volume varied from -0.7 to _0.5. I was expecting the Album Volume and Track Volume to go to 0.0 since the file itself was being set to 89db. Then I took the same 20 files and did a "Level Track Volume". I did an "Analyze volume" and all went to "Album Volume" of -6.9 with "Track Volume" varying around -6.0 (-4.9 to -7.9). I don't understand, shouldn't the two sound dramatically different in volume? How can I manually alter the files to hear a dramatic difference so that I can better understand what each ID3 tag does to the file?ĥ) I took 20 files from various albums. I then manually changed the "track volume" on # one to +10.0 db and # two to -10.0 db and when I playback they also sound the same level. Play has a check mark on "level playback volume" and when I play them both they sound the same level. I selected both and did "Analyze volume" which changed "track Volume" for # one to -0.1db and # two to -0.5. does this a) actually alter the file or the ID3 Tags or b) does it only affect how the music plays back based on already established ID3 Tags?Ĥ) I took two test files. Play) if you put a check mark on LEVEL PLAYBACK VOLUME by pressing PLAY LEVEL PLAYBACK VOLUME. Why can't I change "Album Volume" or how CAN I change it?ģ) Under the heading at the top (File, Edit. I assume that it is an ID3 Tag which I should be able to manually alter (like I can the "Track Volume"). (are they ID3 Tags?)Ģ) I can not manually change the "Album Volume" numbers. THANKSġ) What specifically are the columns labeled "Track Volume" and "Album Volume". I would really appreciate any answers to the specific questions I have listed and any comments that would correct misunderstandings in my assumptions. I have several questions and at the bottom of this I have included my assumptions. I am trying to understand how to make two songs play back at the same volume level using ID3 Tags not physically altering the file (which I assume is "analyze volume" as opposed to "level track volume" which will alter the physical file). I am brand new to manipulating sound and new to MediaMonkey (MM).
