sound:compute PR over time for orders

Last update: 31.07.2026

Version: 0.0.0

Description

Compute the Prominence Ratio (PR) over time of a signal, for specific order(s), where PR is defined in accordance with the ECMA-418-1 (formerly ECMA-74, Annex D) and ISO7779:1999 standards. This is applicable for tones whose frequencies are between 89.1 Hz and 11,220 Hz.

Inputs

Input Name Expected type(s) Description
Pin 0
Required
input_signal field Input signal in Pa on which to compute the PR over time for the specified orders.
Pin 1
Required
rpm_profile field Profile of RPM over time associated with the input signal. Must have the same length and same sampling frequency as the input signal.
Pin 2
Required
orders_numbers vector<double> List of the order numbers for which to compute PR.

Outputs

Output Name Expected type(s) Description
Pin 0 orders_pr_over_time fields_container PR over time, in dB, for each order number specified in input orders_numbers.
Pin 1 rpm_profile_resampled field RPM over time, resampled to match the PR computation time steps.

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.
