+################################################
+
+### Each scene must start with the sceneN tag
+### Specify the mono source filename (the program will search for it in the input_path folder)
+### Specify azimuth and elevation for each input source
+### Note 1: use [val1, val2, ...] for multiple sources in a scene
+### Note 2: use the "start:step:stop" notation for moving sources, where step will be applied in 20ms frames
+
+### Note 3: we're using right-handed coordinate system with azi = 0 pointing from the nose to the screen
+### azimuth: float, [-180,180]; positive indicates left
+### elevation: float, [-90,90]; positive indicates up
+### distance: float, tbd: default: 1
+### spread: float, [0,360]; spread in angles from 0 ... 360˚

+### Output format
+format: "ISM2"
+
+### Output sampling rate in Hz needed for headerless audio files; default = 48000
+fs: 48000
+
+### Any relative paths will be interpreted relative to the working directory the script is called from!
+### Usage of absolute paths is recommended.
+### Do not use file names with dots "." in them! This is not supported, use "_" instead
+### For Windows users: please use double back slash '\\' in paths and add '.exe' to executable definitions
+
+### Input path to mono files
+input_path: "./items_mono"
+
+### Output path for generated test items and metadata files
+output_path: "./items_ISM2"
+
+### Target loudness in LKFS; default = null (no loudness normalization applied)
+loudness: -26
+
+### Pre-amble and Post-amble length in seconds (default = 0.0)
+preamble: 1.0
+postamble: 1.0

+### Scene description
+################################################
+
+### Each scene must start with the sceneN tag
+### Specify the mono source filename (the program will search for it in the input_path folder)
+### Specify azimuth and elevation for each input source
+### Specify the overlap length in seconds for each input source (negative value creates a gap)
+### Note 1: use [val1, val2, ...] for multiple sources in a scene
+### Note 2: use the "start:step:stop" notation for moving sources, where step will be applied in 20ms frames
+
+### Note 3: we're using right-handed coordinate system with azi = 0 pointing from the nose to the screen
+### azimuth: float, [-180,180]; positive indicates left
+### elevation: float, [-90,90]; positive indicates up
+### distance: float, tbd: default: 1
+### spread: float, [0,360]; spread in angles from 0 ... 360˚
+### gain: float, [0,1]
