 # sound:xtract transient detection

 Last update: 31.07.2026 

**Version: 0.0.0**

## Description

Transient components detection and extraction using the XTRACT algorithm.

## Inputs

InputNameExpected type(s)Description**Pin 0**   
Requiredinput\_signal[`fields_container`](../../core-concepts/dpf-types.md#fields-container), [`field`](../../core-concepts/dpf-types.md#field)Signal(s) from which we want to extract transient components, as a field or fields\_container. When inputting a fields\_container, each signal (each field of the fields\_container) is processed individually.**Pin 1**   
Requiredinput\_parameters[`generic_data_container`](../../core-concepts/dpf-types.md#generic-data-container)Structure that contains the parameters of the algorithm:  
  
\* Lower threshold (float), between 0 and 100  
\* Upper threshold (float), between 0 and 100  
  
This structure is of type Xtract\_transient\_parameters (see this class for more details).## Outputs

OutputNameExpected type(s)Description**Pin 0**output\_transient\_signals[`fields_container`](../../core-concepts/dpf-types.md#fields-container), [`field`](../../core-concepts/dpf-types.md#field)Transient signal(s), as a field or fields\_container (depending on the input).**Pin 1**output\_non\_transient\_signals[`fields_container`](../../core-concepts/dpf-types.md#fields-container), [`field`](../../core-concepts/dpf-types.md#field)Non-transient signal(s): original signal minus transient signal, as a field or fields\_container (depending on the input).## Configurations
