ID3 tags are simply a property of an .mp3 file which contain information about the artist, album, year of release, and other metadata. It's how .mp3 players and media libraries identify and sort .mp3 files.
In xLights, the option to overwrite them won't change your music or your sequence. There's no good reason to overwrite media tags, but there's also not a super solid reason not to.
I didn't know that use of .wav in xLights was up on GitHub and available for testing. So that is where I am headed and if it works, I will never use another mp3 file.
My original post was pointed at the fact that when converting an existing .wav file or even rendering an Audacity .aup work file to an .mp3 for xLights, that the process adds a few frames to the beginning and end of a song; thus making it longer in length.
I projection map my whole house. So lining up video and audio is a big deal for me.. Also, I program each song independently for speed purposes, then go back and string sequence to sequence and make one continuous 18 minute file. It's those extra frames that have caused me much grief and time over the last 4 years in which I have done this.
I was hoping "ignore" also meant "omit". but now I know it does not mean that.
Anyway, I am hoping the now available use of .wav will save me some time. Thank you taking time to reply.
