Settings

Edit ▸ Settings… (Ctrl+,), or the Settings button beside the input list.

Changes take effect when you press Save. Tool detection re-runs immediately, so an encoder you have just pointed at becomes available without a restart.

Tool paths

Row What it points at
FFmpeg The ffmpeg executable. Required.
ffprobe The ffprobe executable. Required.
qaac Apple AAC encoder. Also needs CoreAudioToolbox installed.
fdkaac Fraunhofer FDK AAC encoder.
opusenc Standalone Opus encoder, part of opus-tools.
DeeZy The DeeZy executable.
Dolby Encoding Engine dee. Usually found beside DeeZy automatically.
TrueHDD truehdd. Usually found beside DeeZy automatically. Needed for Atmos and AC-4.

Leave a row empty to use PATH. An empty row is the normal case - you only need to fill one in when the tool is not on PATH, or when you want a specific build rather than whichever one PATH finds first.

A path you set must point at a real file. Unlike an empty row, a configured path that does not resolve is reported as an error rather than falling back to PATH - otherwise a typo would look like it worked while silently running a different binary.

See Required and optional tools for the full discovery order, including how dee and truehdd are located inside DeeZy's own apps/ layout.

Default output folder

Where generated output paths are placed. Leave it empty to put outputs beside their input file.

This sets the starting point only; the output path stays editable per job on the Output tab.

Appearance

Automatic, Light, or Dark. Automatic follows the operating system, and switches live when the system theme changes. Icons are re-tinted to match, so neither theme leaves you with invisible toolbar glyphs.

Overwrite

Allow queued jobs to replace existing outputs.

This is the default for the Collision policy checkbox on the Output tab, not an override. With it off, a generated output name that collides with an existing file is numbered automatically instead of replacing it.

You can still tick or untick the per-job checkbox for any individual job.

What else is remembered

Beyond this dialog, the application persists your window position and size, whether it was maximised, the splitter positions, the last folder you added files from, and the last encoder configuration you used. These are saved automatically - there is nothing to configure.

All of it lives in settings.json; see Files and locations.
