Start by running a single scene to verify settings. Output includes both audio and optional metadata files. You can enable multiprocessing by setting `multiprocessing: true`.
The addition of custom background noise at specific level is supported for the STEREO and SBA formats only. For ISMs it's not applicable. For OMASA and OSBA formats, it is expected that the backround noise is provided in the FOA/HOA2/HOA3 format as the first item in the `input` list.
### Item processing
The input has to be in the folder `experiments/selection/P800-{X}/proc_input_{l}`. If item generation is performed previous to this step, the corresponding files are already in the right folder.
