## 项目历史与用法
FAAD2 is the Freeware Advanced Audio Decoder, a GPL-licensed AAC decoder with both a library and a small command-line frontend.
### 项目历史
The project comes from the early-2000s AAC tooling around FAAC/FAAD. Its README identifies FAAD2 as an HE, LC, MAIN, and LTP profile MPEG-2 and MPEG-4 AAC decoder with SBR support, and the copyright block credits M. Bakker and Nero AG for 2003-2005 code.
Later maintenance has focused less on new user-facing features and more on keeping a mature codec implementation buildable and safe. The changelog records DAB+ support in 2.7, renewed build-system work in the 2.9 and 2.10 series, and a large 2.11.0 cleanup with CMake, Bazel, CI, fuzzers, OSS-Fuzz integration, and many crash or CVE-related decoder fixes.
### 采用历史
FAAD2 became a familiar low-level dependency for Unix audio stacks because it provides a standalone AAC decoder library plus the `faad` frontend. Its adoption story is typical of codec packages: quiet, long-lived, and maintained because many media workflows need reliable decoding of older and current AAC files.
### 使用方式
Users normally encounter FAAD2 as the `faad` command or as libfaad linked by other media software. The source tree explicitly separates the command-line frontend, public include files, API docs, and decoder library, which is why distributions can package both executable and library use cases.
### 为什么软件包爱好者会关心
FAAD2 matters to package maintainers because it sits at the uncomfortable intersection of old multimedia standards, GPL licensing, patent warnings, and security hardening. The recent changelog entries around fuzzing and CVE fixes are exactly the sort of maintenance that keeps legacy codec packages viable.
### 时间线
- 2003-2005: Core FAAD2 copyright period credited to M. Bakker and Nero AG.
- 2009: FAAD2 2.7 adds DAB+ support.
- 2019: FAAD2 2.9.0 includes build cleanup and multiple CVE fixes.
- 2023: FAAD2 2.11.0 adds CMake, Bazel, CI, fuzzers, and broad decoder hardening.
- 2025: FAAD2 2.11.2 adds a BUILD_FAAD_CLI option and additional frontend fixes.
### Related projects
- FAAC is the companion AAC encoder project historically distributed from the same SourceForge project area.
- FAAD2 is commonly compared with other media codec components that provide small command-line frontends over reusable C libraries.
