Real Time Quality Evaluation with HASQUE
Listening test simulation at terminals with analogue audio interfaces.
Features: 24 Bit 48 kHz A/D converter, Automatic level adaptation
Hardware tester with programmable signal generators, Programmable Task Interpreter, PTT control
Scaling according to ITU-T P.862.1 und ITU-T P.862.2 or individual programmable
Statistics: MOS, Delay, Speech Interrupts
HASQUE measurement systems are used among others by the „Bundesanstalt für den Digitalfunk der Behörden und Organisationen mit Sicherheitsaufgaben”-(BDBOS) for certification of digital radio devices and control centres.
The search for new solutions requires new measurement principles making observations of cause and effect possible. We develop new real time measurement principles for individual properties of audio systems making cause and effect visible.
Quality enhancement of known telecommunication systems is possible by hearing adequate parameterization.
We offer the optimization of your product with the aid of our adaptive measurement systems and provide you with new signal processing principles for your future products.
