Software to compress audio files with GUI?

Hi!

I do use these two programs for single and batch photo and video compression. They let you cut the file size by ~80% without any noticeable loss in quality, but can not find anything similar for my huuuge music collection. Any reccomendations please?

CompressO -> https://github.com/codeforreal1/compressO Caesium Image Compressor -> https://github.com/Lymphatus/caesium-image-compressor

Save some space, guys!
