The README/manpage identifies the tool as a frontend for the libfdk-aac encoder rather than a standalone codec implementation. Development in 2013 was rapid, adding raw input, metadata tagging, gapless mode, CAF input, M4A details, SBR options, and generated manpage material. Later releases focused on compatibility with newer libfdk-aac APIs, Visual Studio project updates, Windows path support, parser checks, and maintenance bumps. ### Adoption history The supplied package metadata shows the encoder frontend packaged as fdkaac or fdk-aac-encoder across Homebrew, Debian/Ubuntu, Fedora, Nix, Arch, Alpine, and other distributions. That spread reflects the demand for an installable CLI wrapper around Fraunhofer FDK AAC in audio conversion workflows. The GitHub project is smaller than general-purpose media tools, but it persists because it fills a specific packaging gap: users often need a simple executable that exposes libfdk-aac profiles, bitrate modes, M4A tagging, and streamable AAC transport formats. ### How it is used The README says fdkaac reads linear PCM audio in WAV, raw PCM, or CAF form and encodes it to M4A or AAC. It can read from stdin, write to stdout for streamable transport formats, copy CAF tags to M4A, set metadata fields, and choose profiles such as AAC LC, HE-AAC, HE-AAC v2, AAC LD, and AAC ELD. Package users typically encounter it in shell pipelines or media scripts where libfdk-aac quality or profile support is desired without building a larger transcoding stack around it. ### Why package nerds care fdk-aac-encoder is package-nerd-relevant because the Homebrew formula name describes the dependency relationship while the executable keeps the upstream fdkaac name. That split is common in media packaging, where the user-facing binary, library dependency, and formula name are not identical. Its history also tracks the practical edge cases that matter to audio packagers: gapless playback signaling, SBR behavior, CAF and WAV parsing, M4A metadata, Windows builds, and compatibility with evolving libfdk-aac APIs. ### Timeline - 2013: Repository created and v0.0.1 initial release work began. - 2013: v0.3.0 added `--moov-before-mdat`; v0.4.x added CAF input and SBR-related options. - 2018: Version 1.0.0 updated for FDKv2 API changes and fixed LD/ELD priming behavior. - 2026: v1.0.7 tag published. ### Related projects - fdkaac is a frontend for libfdk-aac and depends on that library for AAC encoding. - It overlaps operationally with larger audio transcoders, but its upstream documentation presents it as a direct encoder CLI rather than a general media framework. ### Sources - - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** fdk-aac-encoder - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - fdk-aac-encoder: normalized package name match | nixpkgs package indexes: pkgs/by-name/fd/fdk-aac-encoder/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Debian apt - fdkaac - 1.0.6-0.1: installed executable or alias match | Debian stable package indexes: fdkaac from https://deb.debian.org/debian/dists/stable/contrib/binary-amd64/Packages.xz | command line encoder frontend for libfdk-aac | https://github.com/nu774/fdkaac - Ubuntu apt - fdkaac - 1.0.0-1build1: installed executable or alias match | Ubuntu 24.04 LTS package indexes: fdkaac from https://archive.ubuntu.com/ubuntu/dists/noble/multiverse/binary-amd64/Packages.gz | command line encoder frontend for libfdk-aac | https://github.com/nu774/fdkaac - apk - fdkaac - 1.0.6-r0: installed executable or alias match | Alpine Linux edge package indexes: fdkaac from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Command line frontend for libfdk-aac | https://github.com/nu774/fdkaac - apk - fdkaac-doc - 1.0.6-r0: installed executable or alias match | Alpine Linux edge package indexes: fdkaac-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Command line frontend for libfdk-aac (documentation) | https://github.com/nu774/fdkaac - dnf - fdkaac - 1.0.7-1.fc45: installed executable or alias match | Fedora Rawhide package metadata: fdkaac from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | Command line frontend for libfdk-aac encoder | https://github.com/nu774/fdkaac - pacman - fdkaac - 1.0.7-1: installed executable or alias match | Arch Linux sync databases: fdkaac from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | Command line encoder frontend for libfdk-aac | https://github.com/nu774/fdkaac ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://www.automicvault.com/pkg/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [fdk-aac](https://www.automicvault.com/pkg/brew/fdk-aac/) - Runtime dependency declared by Homebrew. - [autoconf](https://www.automicvault.com/pkg/brew/autoconf/) - Build dependency declared by Homebrew. - [automake](https://www.automicvault.com/pkg/brew/automake/) - Build dependency declared by Homebrew. - [libtool](https://www.automicvault.com/pkg/brew/libtool/) - Build dependency declared by Homebrew. - [pkgconf](https://www.automicvault.com/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [faac](https://www.automicvault.com/pkg/brew/faac/) - Shares av.db curated category or tags: aac, audio-encoder, cli, media. - [faad2](https://www.automicvault.com/pkg/brew/faad2/) - Shares av.db curated category or tags: aac, cli, media. - [flake](https://www.automicvault.com/pkg/brew/flake/) - Shares av.db curated category or tags: audio-encoder, cli, media. - [a52dec](https://www.automicvault.com/pkg/brew/a52dec/) - Shares av.db curated category or tags: cli, media. - [aalib](https://www.automicvault.com/pkg/brew/aalib/) - Shares av.db curated category or tags: cli, media. - [ab-av1](https://www.automicvault.com/pkg/brew/ab-av1/) - Shares av.db curated category or tags: cli, media. - [abcde](https://www.automicvault.com/pkg/brew/abcde/) - Shares av.db curated category or tags: cli, media. - [av1an](https://www.automicvault.com/pkg/brew/av1an/) - Local package facts share a topical domain.
