AAC (Advanced Audio Coding) is actually an abbreviation of advanced audio coding, AAC is developed by Fraunhofer IIS-A, Dolby and AT& An audio format co-developed by T, which is part of the MPEG-2 specification. The algorithm used by AAC is different from the algorithm used by MP3, and AAC improves encoding efficiency by combining other functions. AAC's audio algorithm is far more powerful than some previous compression algorithms (such as MP3, etc.).
It also supports up to 48 tracks simultaneously, 15 low-frequency tracks, more sample rates and bit rates, compatibility with multiple languages, and improved decoding efficiency. In short, AAC provides better sound quality at 30 percent smaller size than MP3 files, which is called the \"21st century data compression method\" in the mobile phone industry.
ACC decoding chip is a chip used for decoding digital audio signals, its main function is to decode digital audio signals to analog audio signals. By decoding and processing digital audio signals, this chip can achieve high-fidelity audio output, providing a clearer and more realistic sound quality experience. ACC decoding chip is widely used in audio equipment, such as headphones, speakers, speakers, etc., which can effectively improve the sound quality performance of audio equipment and bring users better music enjoyment. At the same time, it also has the characteristics of low power consumption, high stability and low cost, which is suitable for all kinds of consumer electronic products.
