- `input`: list of mono `.wav` files

- `azimuth` / `elevation`: spatial placement (°)

- `level`: loudness in dB

- `shift`: timing offsets in seconds

- `shift`: signal offset/overlap in seconds

- `background`: background noise file (applicable to STEREO and SBA only)

- `background_level`: level of the background noise (applicable to STEREO and SBA only)



Dynamic positioning (e.g., `"-20:1.0:360"`) means the source will move over time, stepping every 20 ms.



The total duration of the output signal can be controlled using the `duration` field. The output signal may optionally be rendered to the BINAURAL format by specifying the `binaural_output` field.

Dynamic positioning (e.g., `"-20:1.0:360"`) means the source will move over time, stepping every 20 ms. The maximum total duration of the output signal can be controlled using the `duration` field. The output signal may optionally be rendered to the BINAURAL format by specifying the `binaural_output` field. The `shift` parameter ensures time adjustment (offset) of the input signal (positive value delays the signal). Aternatively, the notation `X(i_ref)` generates overlap by `X` seconds from the reference signal `i_ref` (0-based index) (positive value creates gap).



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`.
