Key Features

A strong reputation of quality

dBSonic inherits the long experience of two major companies in the field
of sound and vibration: 01dB-Metravib & CORTEX Instruments, leader in
psychoacoustics.

• Calculations and algorithms internationally recognized as robust and representative of human perception
• Advanced mathematical models for further analysis: wavelet, ASP, order analysis, IIR filters, equalization, ...

A fast and powerful software

• Hundreds of files analyzed in a few clicks thanks to dBSonic batch mode
• Synthetic tables of results available for comparative analyses
• Quick automatic report for a fast reporting to project managers

Auditory related analysis & sound design

• The missing link between analysis and perception! ......between what you see and what you hear!
• Fine and resolving graphical display enabling to pick up, modify tricky components in the « auditory image »
• Direct virtual sound prototyping related to sound quality targeting

Multi-platform data acquisition up to 32 channels

• NetdB-DAQ12/32, Orchestra, Harmonie, Symphonie, Sound cards

With dBSonic, annoying sound components are easily analyzed, identified, documented and removed by creating targets sounds with its most innovative sound design tools PerceptualXplorer and FilterXplorer.
Four packages (including different modules of dBSonic) have been derived in order to fit to the need of your application:

• The basic psychoacoustic package. This package is ideal for entering psychoacoustics at a low price on the base of relevant, robust and established psychoacoustic models. It includes the basic (BA), psychoacoustic (PSY) and documentation (DOC) modules.
• The automative dedicated package. This package is the basic entry for the analysis of sound signals versus RPM/engine orders and on-line/offline filtering capabilites. It includes the basic (BA), the sound editor (ED) and RPM modules.
• The advanced automative package. This package allows to perform some advanced standard and psychoacoustic analysis for engine application. It includes the basic (BA), the psychoacoustic (PSY), the (RPM), and the documentation (DOC) modules.
• The filtering package. This package is dedicated to people interested in getting all the main psychoacoustic functions of the software and the battery of all filtering capabilities of the software. These are filter design (set up of filter bank including frequency and order filters), real time and off line filtering capabilites. This package includes the basic (BA), psychoacoustic (PSY), documentation (DOC) and filter editor (ED) modules.
