The original author and maintainer was David Collett from 2006 to 2008; K. Henriksson became the primary author and maintainer afterward. The manual records the same authorship split, with copyright for David Collett in 2006-2008 and K. Henriksson afterward. ### Project history The project's role is a neat filesystem trick for lossless music collections. A user mounts a source directory and a mountpoint, and applications browsing the mountpoint see .mp3 names for the underlying FLAC/Ogg files. Reads initialize decoders and encoders, fill an internal per-file buffer, and emit MP3 data without requiring the user to keep a second converted library. The README gives examples for FUSE mounts and fstab entries, and describes practical uses such as feeding hardware or software that only understands MP3. ### How it is used Its major milestones track the broadening of that original idea. The news file lists an initial 0.01 release in 2006, a 0.30 release that added better documentation, bitrate selection, LAME quality settings, and metadata improvements, a 0.9 rewrite of the transcoding code around codec classes, and a 1.0 release that added Ogg Vorbis decoding, VBR MP3 encoding, logging improvements, and a more modern C++11 codebase. In package managers it sits at the intersection of audio tooling and filesystem integration; Homebrew exposes it as a FUSE-dependent formula with FLAC, LAME, libid3tag, and libvorbis in its dependency chain. ### Sources - - - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** mp3fs - **Version Scheme:** 0 - **Revision:** 5 - **Requirements:** linux - **Bottle Stable Root URL:** - **Deprecated:** yes - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Debian apt - mp3fs - 1.1.1-1+b3: normalized package name match | Debian stable package indexes: mp3fs from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | FUSE filesystem for transcoding FLAC to MP3 on the fly | https://khenriks.github.io/mp3fs/ - Nix - mp3fs: normalized package name match | nixpkgs package indexes: pkgs/by-name/mp/mp3fs/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - mp3fs - 1.1.1-1build4: normalized package name match | Ubuntu 24.04 LTS package indexes: mp3fs from https://archive.ubuntu.com/ubuntu/dists/noble/multiverse/binary-amd64/Packages.gz | FUSE filesystem for transcoding FLAC to MP3 on the fly | https://khenriks.github.io/mp3fs/ - dnf - mp3fs - 1.1.1-16.fc44: normalized package name match | Fedora Rawhide package metadata: mp3fs from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | FUSE filesystem to transcode FLAC to MP3 on the fly | https://khenriks.github.io/mp3fs/ - MacPorts - mp3fs: normalized package name match | MacPorts ports tree: fuse/mp3fs/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [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. - [flac](https://www.automicvault.com/pkg/brew/flac/) - Runtime dependency declared by Homebrew. - [lame](https://www.automicvault.com/pkg/brew/lame/) - Runtime dependency declared by Homebrew. - [pkgconf](https://www.automicvault.com/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [btfs](https://www.automicvault.com/pkg/brew/btfs/) - Shares av.db curated category or tags: cli, filesystem, filesystems, fuse, system. - [dwarfs](https://www.automicvault.com/pkg/brew/dwarfs/) - Shares av.db curated category or tags: cli, filesystem, filesystems, fuse, system. - [erofs-utils](https://www.automicvault.com/pkg/brew/erofs-utils/) - Shares av.db curated category or tags: cli, filesystem, filesystems, fuse, system. - [ext4fuse](https://www.automicvault.com/pkg/brew/ext4fuse/) - Shares av.db curated category or tags: cli, filesystem, filesystems, fuse, system. - [fuse-zip](https://www.automicvault.com/pkg/brew/fuse-zip/) - Shares av.db curated category or tags: cli, filesystem, filesystems, fuse, system. - [libfuse](https://www.automicvault.com/pkg/brew/libfuse/) - Shares av.db curated category or tags: cli, filesystem, filesystems, fuse, system. - [ntfs-3g](https://www.automicvault.com/pkg/brew/ntfs-3g/) - Shares av.db curated category or tags: cli, filesystem, filesystems, fuse, system. - [ratarmount](https://www.automicvault.com/pkg/brew/ratarmount/) - Shares av.db curated category or tags: cli, filesystem, filesystems, fuse, system. - [rofs-filtered](https://www.automicvault.com/pkg/brew/rofs-filtered/) - Local package facts share a topical domain.
