 # sound:sound composer - generate sound from harmonics (1 parameter) source

 Last update: 03.06.2026 

**Version: 0.0.0**

## Description

Generate a sound from a harmonics (1 parameter) model, according to a given evolution vs time of the control parameter (the RPM).

## Inputs

InputNameExpected type(s)Description**Pin 0**   
Requiredsource\_harmonics[`fields_container`](../../core-concepts/dpf-types.md#fields-container)Harmonics (1 parameter) model, as a fields container. Each field contains the level of all orders (the harmonics), at a corresponding RPM value (control parameter). Each field contains the same number of orders, each with the same order numbers, as in the other fields of source\_harmonics. The order numbers are stored in the time-frequency support of the field. The control parameter (RPM) vector is stored as the support of the fields container. Levels must be provided in Pa^2. The unit must be specified in each field's unit.**Pin 1**   
Requiredrpm\_control[`field`](../../core-concepts/dpf-types.md#field)RPM value vs time, as a field.**Pin 2**sampling\_frequency[`double`](../../core-concepts/dpf-types.md#standard-types)(Optional) Sampling frequency of the generated sound, in Hz. Default: 44100 Hz## Outputs
