Which sound quality is better, OGG or AAC?

Aac has better sound quality.

The reason for this is the following:

First of all, let me talk about the characteristics of aac and ogg. Aac is characterized by high sampling rate and multi-channel. The sampling rate of mp3 and cd is around 44khz, and aac is divided into several grades, and the highest can reach above 90khz. At the same bit rate, the quality of aac is higher. Ogg is characterized by open source, no patent restrictions and so on. The sound quality is similar to MP3, but smaller.

ACC Advanced Audio Coding (AAC) is an audio coding technology based on MPEG-2. By Flawn Hof IIS, Dolby Lab, in&; T, Sony (Sony) and other * * * companies cooperate to develop, to replace the MP3 format. In 2000, after the appearance of MPEG-4 standard, AAC re-integrated its characteristics and added SBR technology and PS technology, also known as MPEG-4 AAC, to distinguish it from the traditional MPEG-2 AAC.
