libfdk-aac is a software library that provides encoding and decoding functionality for the Advanced Audio Coding (AAC) format. It is developed by Fraunhofer IIS, the same organization that created the AAC audio codec.
AAC is a widely used audio codec that offers high-quality audio compression with efficient file sizes. It is the default audio codec for various applications and platforms, including digital broadcasting, streaming services, and mobile devices. AAC is known for its ability to deliver excellent audio quality at lower bit rates compared to other codecs.
libfdk-aac is considered to be one of the highest quality AAC encoders available and is known for its exceptional audio encoding performance. It provides a range of features and options for fine-tuning the encoding process, allowing developers to optimize audio quality and file size based on their specific needs.
In addition to encoding, libfdk-aac also supports AAC decoding, enabling the playback and processing of AAC-encoded audio streams. This makes it a comprehensive library for handling AAC audio data in various applications and systems.
It’s worth noting that libfdk-aac is released as a library under the Fraunhofer FDK AAC License, which has specific licensing terms. Therefore, it is essential to review and comply with the license requirements when using the library in your projects.
