Looking for an rpm, flatpak or appimage that checks to see if .flac files are truly loseless quality.
You must log in or register to comment.
Compare the actual audio you want:
- If you have a FLAC, put it into Audacity/Tenacity
- Export it with some codec
- drag-drop this file to the same window, add it as second track
- apply the effect “invert” on the compressed stream
- play both at once
You will only hear hisses, maybe more. Its different between every codec and it shows the actual difference between the audio information.
define truly lossless please. Does it mean checking if the audio has lost any high frequencies like in mp3?
