Transmission scenarios like VoLTE, USB, A2B®, and Bluetooth® or devices under test like mobile phones, hands-free terminals, ANC headphones, ICC systems, and smart speakers: ACQUA is the highly sophisticated measurement and analysis software for electroacoustic tests for optimizing voice quality and audio quality. The software in combination with the hardware platform labCORE forms a precise, automated and flexible system for R&D, conformance tests and quality control of devices and systems.

ACQUA includes a multi-channel analysis system for diagnosis of acoustic and/or electric transmission paths up to 192 kHz. With the measurement and analysis software, users can gather and evaluate measurement data in a simple and quick manner via measurement descriptors (SMD; Single Measurement Descriptor). These SMDs are pre-defined, adaptable and embedded in the database structure. All telecommunication-specific tests comply with international standards (for example ETSI, ITU, 3GPP, GCF, PTCRB, GSMA).

Thus, ACQUA is the reliable basis for the complete measurement chain: From the generation of complex excitation signals through the automated conduct of measurements and the analysis of measurement signals to secure storage and documentation.

Highlights

  • Measurement and analysis software for automated testing voice quality and audio quality of different devices
  • Powerful data acquisition and analysis system for electroacoustic tests with sampling rates up to 192 kHz
  • Numerous important international standards in audio and telecommunications are implemented as editable data bases for the use in ACQUA (ACQUA standards)
  • Standards developed by HEAD acoustics (HEAD acoustics Quality Standards) are available for a wide range of applications
Measuring chamber and laboratory. The ACQUA software is used on the computer.

Applications

  • Electroacoustic tests to optimize voice quality and audio quality (algorithms, devices and systems)
  • Conformance tests according to telecommunication standards
  • Research and development (R&D)
  • Quality control

Features

  • In ACQUA, test procedures and hardware equipment are configured and controlled database-driven.
  • The software contains pre-defined measurements for fast, automated and guided electroacoustic tests according to various international standards.
  • The user-friendly “Quick Start” menu provides quick access to favorite projects and to a dynamic list of recent projects and test objects.
  • ACQUA offers outstanding possibilities for signal preparation and manipulation.
  • The software allows analysis in the time and frequency domain.
  • A variety of perceptively motivated quality measures is available.
  • The analysis software enables electroacoustic tests for improving voice quality and audio quality with any test signals: real speech, sine, sine stepped sweep, multi-sine, pseudo noise, artificial voice (P.50), pink noise, white noise, Hoth noise, test signals according to ITU-T recommendation P.501 (e.g. composite source signal).
  • ACQUA stands out through comfortable and useful report and documentation functions (e.g. A/B comparison of multiple measurement objects, benchmarking, Quality Pie reports).
  • ACQUA provides possibility to build custom standards and measurement sequences.
  • The "Workplace Settings" allow easy and intuitive management and configuration of all hardware components in the lab.
  • The complete measurement chain is clearly arranged in ACQUA – from connection of the analysis software over labCORE to the artificial head measurement system, third party equipment, and the device under test.
  • The measurement and analysis software can be extended with a wide variety of software options (ACOPTs) and can thus be individually adapted to specific fields of application.

Variants

ACQUA analysis software variants on laptop

ACQUA Full-license

This is the full version of the measurement and analysis software with maximum range of features and options.

 
ACQUA analysis software variants on laptop

ACQUA Workplace

This ACQUA version saves valuable laboratory capacity. ACQUA Workplace enables to prepare, analyze and document measurements but does not allow for measurements to be conducted. All measurement cards (SMD; Single Measurement Descriptor) can be created, opened, and edited without restrictions – even if the ACOPTs or ACQUA standards required for the measurement are not available. ACQUA Workplace is also available as network license.

Optionally, this analysis software version can be upgraded to the full-license version “ACQUA Full-license” with “UG ACQUA Workplace”.

ACQUA Compact

ACQUA Compact (Code6860) is a cost-effective solution for specific measurement tasks. It includes the ACQUA Compact software platform and the basic labCORE frontend (Code 7700).

ACQUA Compact has certain technical limitations compared to an ACQUA full-license system:

  • Not all ACOPTs available
  • Only allows tests on two measurement objects per project
  • Only one project open at a time
  • No archiving of time signals into the database
  • Limited possibilities of manual signals analysis by using the ACQUAlyzer

Additional labCORE extensions, ACQUA options, international specifications implemented in ACQUA standard and HEAD acoustics Quality Standards can be added according to the given application.

Optionally, this version can be upgraded to the full-license version with “UG ACQUA Compact”.
