Communication Analysis System: HEAD acoustics launches new ACQUA version
ACQUA 3.5.100 offers innovative features that further simplify daily measurements
HEAD acoustics launches ACQUA 3.5.100, the new version of the Communication Analysis system for evaluation of speech and audio quality. The update includes innovative features that simplify the user’s daily measurements. A special highlight refers to the super-wideband- and fullband-capable EVS codec (Enhanced Voice Services). Due to the new hardware extension MFE VIII.1-SPE (Single Processing Extension), the user can also enable the EVS codec on primary measurement front end. The key advantage of this is that the audio codec EVS can be combined with IP network impairments such as delay, jitter or packet loss.
With regard to the application of IP network impairments, there is another innovation which affects the corresponding software option for the measurement front end MFE VIII.1. The option MFE VIII.1-IMP allows the user to simulate different IP network impairments such as delay, jitter or packet loss directly at the signal source and to apply the network impairments to the outgoing IP packets of the MFE VIII.1. ACQUA 3.5.100 offers new editing and display possibilities for the adjusted network impairments. Now, they are displayed as table and as “Delay vs. Time” diagram. In addition, the jitter of the device under test can be measured at the MFE VIII.1 and can be queried via ACQUA.
Furthermore, the import and export of Wave files has been revised: So far, the “Full Scale” value of the Wave file could be mapped to a world value of the imported file. Now, a target level can also be set for each channel, either as RMS level or as active speech level. In the calculation of the Speech Transmission Index, the user can switch between the old version (IEC 60268-16:2003) and the new version (IEC 60268-16:2011).
About ACQUA
ACQUA is perfectly suited for measuring, analyzing and optimizing different communication devices such as mobile phones, cordless telephones and vehicle applications such as hands-free devices, eCall systems and in-car communication systems. The analysis system supports companies improving the quality of their communication products. With ACQUA, acoustic and / or electric transmission paths up to 24 kHz can be analyzed. In combination with measurement front ends, the dual channel measuring system is capable of analyzing a wide range of single components, complete terminals and transmission networks. A variety of options allows the individual tailoring of the software and its performance to specific fields of application which may range from the evaluation of frequency responses to psychoacoustic models and speech quality analysis systems.
