The sound quality at medium bit rates is better than that of the AAC-LC profile, but in no way justifies this inefficiency.
Due to its much higher encoding and decoding performance compared to AAC-LC, this profile is relatively inefficient. This profile is designed for low to medium bit rates. Due to its advantages in terms of encoding and decoding efficiency and better sound quality at higher bit rates, this profile is the most common profile among all hardware manufacturers and music store providers. This profile is compatible with most AAC-compliant hardware end devices. Here we will briefly introduce the most common profiles.ĭesigned primarily for medium to high bit rates. Above all, they make it easier for hardware manufacturers to use this compression method.
#ADVANCED AUDIO CODEC LOW COMPLEXITY ISO#
In this case, however, from the International Organization for Standardization, or ISO for short. The AAC audio codec has the great advantage that it can deliver (reasonably) good stereo quality at bit rates around 64 kb.Īs for the H.264 video codec, several profiles have been defined for the AAC audio codec. This is where open source solutions like FAAC (Free Advanced Audio Codec) become interesting. However, it comes at a price, and very few operators of video forums and vlogs will invest in the costs of the license. During development, known weaknesses and issues in the MP3 encoding process were taken into account and greatly improved. It was specified as a further development of MPEG-2 in the MPEG-2 standard. AAC is a lossy audio compression method developed by MPEG Group (Moving Picture Experts Group).
