So certain engine software for AutoDJ, such as LiquidSoap, comes with AAC, OGG, and FLAC support but Centova only recognizes MP3. Sad! Competitors like SAM Broadcast Cloud support this.
Why would you want formats like FLAC in autodj? Because when re-encoding tracks, it maintains much better quality and if you move your station from say 128 kbps to 192 kbps, you don't have to reupload all the tracks. (And it's sinful to transcode to a higher bitrate than the original file).
OGG and FLAC use similar tagging system and Liquidsoap already supports the formats, so should be pretty easy to implement.
Would love to see that!
