‘Crystal-clear, high-definition’ voice reports from Aeta's Scoopy+
Aeta Audio Systems has launched a professional mobile HD Voice codec, including the addition of AMR-wideband support, with its Scoopy+ codec/mixer/recorder. The ‘compact’ Scoopy+ is designed for reporters on location, and promises to deliver ‘pristine high quality’ audio, reportedly ‘far exceeding’ what is possible with 2G and 3G networks.
According to the manufacturer, HD Voice delivers higher quality voice transmissions by extending the frequency of range of traditio
nal or narrowband voice calls (300Hz to 3400Hz) out to wideband audio ranges (50Hz to 7000Hz).
One of the key features of the Scoopy+ is that it now supports LTE in 800-, 1800-, and 2600MHz mobile networks, which Aeta claims further enhances its versatility in the field. Scoopy+ LTE (Long Term Evolution) allows high-speed transmission of data during live or recorded reports, providing what Aeta calls a ‘significant advantage’ both in remote areas and in cities.
Aeta has designed Scoopy+ so that it is easy for mobile reporters to use HD Voice where AMR-wideband is available, and automatically switches from wideband to narrowband (standard GSM or UMTS) where necessary, without introducing noise into the signal.
The manufacturer is keen to draw attention to the fact that broadcasting in HD Voice does not add to the broadcaster's costs by requiring extra bandwidth.
Both the portable Scoopy+ and the rack-mounted Scoop4+ can be configured with AMR-WB. Both units provide a large choice of available networks (IP/LL/ISDN/GSM/3G/POTS) and algorithms (G.711, G.722, Mprh Layer II, AAC) with automatic negotiation (5AS), in addition to support for AMR-WB.
