sound:compute 1/3-octave levels from PSD
Last update: 31.07.2026Version: 0.0.0
Description
Compute one-third-octave-band levels from a power spectral density (PSD) input. Twenty-nine bands are considered whose center frequencies range between 25 Hz and 16000 Hz
Inputs
| Input | Name | Expected type(s) | Description |
|---|---|---|---|
| Pin 0 Required |
psd | field |
Input power spectral density (PSD) for the levels' computation, in |
Outputs
| Output | Name | Expected type(s) | Description |
|---|---|---|---|
| Pin 0 | levels | field |
One-third-octave-band levels. The returned level unit is derived from the input PSD's unit (for example, if the PSD is in Pa^2/Hz, the levels will be returned in Pa^2).The field support contains the one-third-octave-band center frequencies. |
Configurations
| Name | Expected type(s) | Default value | Description |
|---|---|---|---|
| mutex | bool |
false | If this option is set to true, the shared memory is prevented from being simultaneously accessed by multiple threads. |
