Freeware Advanced Audio Coder, or FAAC, is a free and open-source software library and command-line tool used for encoding audio into the Advanced Audio Coding (AAC) format. FAAC is designed to provide high-quality audio encoding while being flexible and efficient. The AAC format is widely used for encoding audio in various applications, including music streaming services and digital television broadcasting.
FAAC is written in C and is known for its speed, high encoding quality, and support for a wide range of input audio formats. It is available for various platforms, including Windows, Linux, and macOS, and can be used as a library for inclusion in other software applications or as a standalone tool for encoding audio files.
While FAAC is a reliable and efficient tool for encoding audio into the AAC format, it should be noted that it is no longer actively developed and maintained. As a result, newer and more advanced AAC encoders have emerged and may offer better performance and features.
