AAC is a lossy audio codec designed as the successor to MP3. It achieves better sound quality than MP3 at similar bitrates, making it more efficient for storage and streaming. AAC is the default audio format for Apple devices, YouTube, and many streaming services.
WebM Audio Format
Lossy
WebM is an open, royalty-free media format developed by Google. The audio component typically uses Vorbis or Opus codecs. WebM is optimized for web delivery and is the preferred audio format for HTML5 web applications.
