About OGG and AAC
OGG: OGG Vorbis is a free, open lossy audio format. Android uses OGG for its built-in ringtones and notification sounds, and many games and web apps rely on it.
AAC: AAC is the successor to MP3 and the audio codec behind YouTube, iTunes and most streaming services. A .aac file stores the raw AAC stream without an MP4 wrapper.
