CUETools Advanced Settings: Encoders

Encoders tab

Extension {drop-down list}

Audio file format extension for selected encoder.

Built-in encoder options

Options vary by encoder. Highlight option to see explanation at the bottom of the window.

External encoder options

Note: External encoders (*.exe executables) are not included. These need to be downloaded separately by the user. The external encoder must support stdin (standard input).

Path {textbox}

Path to external encoder executable.

Enter encoder name (e.g. encoder.exe) or if editing an existing encoder, leave the encoder.exe 'as is' and copy the encoder.exe file (and any dependencies) to the CUETools program folder

or

Enter encoder name (e.g. encoder.exe) or if editing an existing encoder, leave the encoder.exe 'as is' and add full path to the location of the encoder.exe file to the system's %PATH% environment variable

or

Enter the full path (e.g. C:\opus\opusenc.exe) if the file is located somewhere else.

Parameters {textbox}

Arguments for external encoder executable (Encoding parameters only. Please refer to the encoder's documentation for more info about usage parameters.). The required placeholder arguments used by CUETools for external encoders are:

"-" : (without the quotes) = stdin (standard input).

%O : will be replaced by the output file name

Optional:

%M : will be replaced by the value from Modes (selected via slider on main screen).

%P : padding metadata block bytes to add to header. (This placeholder is for encoders that support padding, e.g. flake, flac, etc. so CUETools can reserve space to write the metadata after encoding.)

Modes {textbox}

Supported mode values, separated by space character. Linked to the {slider} control under the Audio Output section of the main window.

Name {textbox}

Name of the encoder that will be displayed in the {drop-down list} under the Audio Output section of the main window..

Lossless {checkbox}

Setting is internally linked to the audio file format extension. Greyed out unless you selected a newly registered file format extension.

(plus) {button}

Register a new external encoder. Alternate: Click any encoder name and press the Insert key on your keyboard to register a new external encoder.

(minus) {button}

Remove selected external encoder. Alternate: Select the (*.exe executable) encoder and press the Delete key on your keyboard to remove an existing registered external encoder.
