dScope Software Version 1.2 preview at NAB

Cambridge, UK -April 2006: Prism Sound is using the NAB 2006 platform to announce Version 1.2 of its successful dScope III audio analyzer software.

The new dScope Version 1.2 software, which represents a major upgrade in the functionality of the unit, will incorporate a number of features that have been frequently requested by the audio test community. The new version 1.2 software will provide a package of tools for acoustic measurements and another package for PC audio. The acoustic package will offer transducer test support including the following:

• dBSPL units
• Measurement mic sensitivity and frequency response calibration
• Transfer function using MLS, Impulse response and FFT, or swept-sine method (also useful for electronic/DSP EUTs)
• Dynamic loudspeaker impedance measurement by use of an external ballast resistor in series with the drive unit
• Analogue I/O running optionally at 48kHz as well as 96 and 192kHz

The PC Audio package is aimed at users who need to test the complex devices that appear as part of the PC's audio system (sound cards, Bluetooth headsets etc). Wavetable-based generation and FFT-based analysis via Windows sound devices will be provided, in addition to the full capability of the dScope Series III audio analyzer system hardware.

The versatility of the compact and cost effective dScope III audio analyzer makes it suitable for a wide range of digital and analogue audio applications, which is why it has become the test and measurement tool of choice for so many organisations and manufacturers. Among the market sectors that have embraced dScope are broadcast, multimedia, CD, DVD, computer audio, transducer, digital telephony and communications. dScope III is comprehensive and accurate for R&D applications, portable and intuitive for maintenance or field service and fast, automatic and IT-friendly for the production line.

As well as covering the traditional audio test functions, dScope incorporates all the features needed to work with the latest audio technologies. These include digital interface test tools such as carrier waveform and eye-pattern display, jitter measurement and AES3/IEC60958 channel status generation and analysis as well as support for higher sampling rates. dScope has a uniquely simple, state-of-the-art synchronous multi-tone capability, which can measure dozens of parameters simultaneously.
