Flacon is a free, open-source Mac application that splits and converts audio files — particularly CUE-backed disc images — into individual, properly tagged tracks.
What is Flacon?
Flacon is a GUI front-end for batch audio conversion that specialises in one thing most encoders miss entirely: it understands CUE sheets. Hand it a single large FLAC or WAV rip paired with a CUE file and it will split the album into individual tracks, pull the metadata straight from the cue, convert each track to your chosen format, and write properly named files — all in one pass. There is no fiddling with a timeline scrubber or manually chopping waveforms. You point, configure, click Start, and the results land in a folder that looks like you bought the album from Bandcamp.
What does Flacon do best?
Flacon's standout strength is CUE-sheet splitting combined with lossless-to-lossy transcoding in a single workflow. If you have a library of old rips sitting as monolithic WAV files with companion CUE sheets — common with CD ripping from the mid-2000s — Flacon is the only free Mac tool I have found that handles this without involving the command line at all.
Beyond CUE work, it supports a solid roster of output formats including FLAC, Ogg Vorbis, MP3 (via LAME), AAC, and Opus. You can set per-format quality targets (bitrate or VBR quality level), choose a file-naming template that uses tags, and tell it to embed cover art sourced from the source directory. The interface stays out of the way: a file list on the left, track-level metadata editable inline on the right, and a progress panel that tells you exactly which encoder is running at any moment.
ReplayGain support is a genuine differentiator here — Flacon can calculate and write album-level and track-level ReplayGain tags so your whole library plays back at consistent loudness without normalising the audio itself. That matters if you care about dynamic range, and most people who reach for Flacon do.
Is Flacon free?
Flacon is completely free to download and use. It is released under the GNU Lesser General Public License, so the source code is open and auditable on GitHub. There is no paid tier, no feature unlock, and no nag screen — it is straightforwardly free software maintained by a small community of contributors.
Who should use Flacon?
Flacon is ideal for anyone with a legacy library of CD rips stored as monolithic disc images, audiophiles who archive in FLAC and want to produce AAC or Opus copies for portable devices, and anyone who wants a clean batch-transcoding workflow without touching Terminal. If your entire music collection already lives in per-track files and you never touch CUE sheets, something like Max or XLD may feel more at home — both offer broader format support and tighter integration with MusicBrainz lookups.
Where Flacon lags behind XLD is in the number of supported input formats and metadata provider integrations. XLD can pull AccurateRip verification and query Discogs in one step; Flacon does neither. For straightforward split-and-encode jobs, though, Flacon's focused design means there is nothing extraneous in your way.
How does Flacon compare to XLD and Max?
XLD is the Swiss Army knife of Mac audio conversion — it supports more formats, verifies rips against AccurateRip, and integrates with MusicBrainz. If you rip CDs regularly or need extensive metadata lookups, XLD wins. Max is excellent for high-quality single-format transcoding with a native macOS feel. Flacon's niche is the CUE-split-and-encode pipeline specifically, and it executes that niche with less friction than either alternative. I reach for Flacon when the task is exactly "take this disc image, split it, encode to Opus, tag everything correctly" — for that specific workflow it is faster to set up than XLD and more explicit about CUE handling than Max.
If you have used dBpoweramp on Windows and miss its batch CUE workflow, Flacon is the closest spiritual equivalent on macOS that will not cost you anything.
What are the best Flacon alternatives?
The primary alternatives on macOS are XLD (X Lossless Decoder — free, broader format and metadata support), Max (free, polished native UI, strong for FLAC/ALAC/MP3), and fre:ac (open-source, cross-platform, built-in encoder library). For command-line purists, ffmpeg combined with a shell script can replicate everything Flacon does, but you give up the CUE-parsing GUI entirely. None of the alternatives match Flacon's combination of CUE-first design, ReplayGain calculation, and zero cost.
