I created several sounds during the last few hours and exported all of them as OGG files.
Now I would like to normalize the sound levels of each of them. If I open them in audacity, normalize sound and export as OGG again will the quality get worse?
The worst part is that I used 1/10 quality since they are going for web.
Unfortunately yes : OGG format uses lossy compression, so there is generation loss.
If you’d saved copies as Audacity projects, or WAV or FLAC formats, you can avoid Generation loss.
