Longtime lurker with my first post/?. Thanks for the tip of using RelayGain for multichannel files. Although I have used ReplayGain for 2.0 tracks with Kodi (xbmc user since I first modded an original xbox), I never tried it with MCH FLAC. For MP3 and AAC I use MP3Gain. However, my query is regarding DD 5.1 is there a similar solution. I ask because I have approximately 4,000 music videos from various sources that I shuffle with KODI. MP3Gain works well for mp4 2.0 files but will not work for 5.1 files AAC or AC3. Most of my 5.1 music videos are concert rips while the 2.0 files are captures from various sources (mostly MTV Classic and now Youtube). Any suggests would be greatly appreciated. BTW I find MMH an excellent tool.
