So I’ve upmixed a number of stereo albums to 5.1 flac files, but one double album I’ve upmixed to 5.1 I’d like to playback Gapless like the stereo CD does. I’ve downloaded Audacity but have never used it before. Is that something you could do with Audacity, or is there something better to use? I don’t care if stays as Gapless flac files or needs to be converted to another file type. Suggestions? I looked at Audacity, but it seems to work with mono or stereo files.
