zaq1wsx Posted November 15, 2018 Share Posted November 15, 2018 Which replay gain tags does Poweramp look at? I recently discovered I was doing something wrong with MP3Gain. I used to do analysis + gain, thinking that analysis was just to come up with the numbers and applying gain would write the tags, but know I know that analysis does write the tags and that applying gain actually modifies the files (which I don't want). So in order to test that, i picked the same song and produced 4 versions: 1. a raw one, 2. one with only the tags, 3. one with the gain change without the tags, 4. and one with gain change and tags. I expected that both 1 and 2, and 3 and 4 would sound the same with RG off (with the latter two being quieter) and that with RG on 1 would be the loudest, 4 the quietest, and 2 and 3 sounding the same in the middle. When I tested them on my PC with MusicBee everything worked out nicely (tho it seems it does some counter gain as 3 and 4 sounded the same with RG on). However when I tried it on Poweramp, it sounds the same as if RG was off. I tried both Album and Track gains, and both Apply Gain and Apply Gain/prevent clipping, as well as re-scanning after changing to Apply gain. In the case of MP3Gain it writes 4 APEv2 tags, REPLAYGAIN_ALBUM_GAIN, REPLAYGAIN_ALBUM_PEAK, REPLAYGAIN_TRACK_GAIN, REPLAYGAIN_TRACK_PEAK. I'm wondering if these are the tags Poweramp looks at or not, that may be the cause of it not working? Link to comment Share on other sites More sharing options...
