Ogg vs AAC 2016-06-21 03:24:21 A large majority of my music is in CDs ripped to FLAC. The remainder is purchases from 7Digital in FLAC, a few HDTracks purchases in FLAC, some MP3s from Amazon and some AACs from iTunes.I went through the effort of converting my FLACs to Ogg Vorbis at vbr q 8.0 (probably overkill) for use locally on my phone.I'm a fan of Ogg Vorbis for it's great Linux support, the open source reference encoder and me liking Vorbis comments.Well, the wife and kids bought me an Amazon Echo for Father's Day. In order to use voice command to play music, I need to upload my music to Amazon's cloud. And Amazon's cloud only accepts MP3s and AAC files.I took some FLACs and encoded them to AAC using Foobar2000 with the QAAC plugin set at vbr q 109 (again probably overkill) and sent them off to the Amazon cloud and the Echo happily played them.If I have achieved transparency, I assume there is no difference listening to an AAC file vs an Ogg Vorbis file. They both support ReplayGain and Gapless playback.I understand there are technical difference such as ID3 Tags vs Vorbis Comments, but that kind of stuff doesn't affect my listening to music.Am I missing anything in using AAC over Ogg Vorbis.And, for the curious. I contacted Amazon tech support and confirmed that Amazon does not do a "match" against what they sell. It uploads everything and plays the exact file you upload. So, my uploaded AAC file is not being replaced by an Amazon MP3 file. Which is exactly what I want.
