FLAC vs OGG
Which audio format should you choose?
FLAC wins on truly lossless compression. OGG wins on open-source and royalty-free. For most general use, pick whichever is more compatible with your existing tools — file size and quality differences are usually small at the same encoding settings.
When to use FLAC
Choose FLAC when you need high-resolution music libraries or cd ripping and audio archiving. Its strengths: truly lossless compression, and smaller than wav by roughly half.
Pros

Choose OGG when you need open-source software and games or web audio in firefox and chrome. Its strengths: open-source and royalty-free, and better quality than mp3 at low bitrates.
Pros
- + Open-source and royalty-free
- + Better quality than MP3 at low bitrates
- + Good streaming support in modern browsers
Cons
- − Not supported by Safari or iOS
- − Limited support in legacy hardware
- − Less common than MP3 or AAC
