Cool sound: The KEM 975 features a non-rotation- symmetrical polar pattern


PLANE AND SIMPLE SOUND CAPTURE Microtech Gefell BY KEVIN EMMOTT


Designed for recording of extensive or moving sound sources, the KEM 975 from Microtech Gefell is a microphone system with a largely frequency- independent polar pattern. Described by the company as a cardioid plane microphone, the


KEM 975 has the features of a cardioid in the horizontal plane and the features of a directional microphone with an operating angle of approximately 30° in the vertical plane.


This means that the polar pattern is adapted to a case where the sound source to be captured is wide in space or moves around in it, while simultaneously suppressing

sound coming from other directions. These could include noises or refl ections that come from ceilings, tables, fl oors or other refl ective areas. Microtech Gefell says its analogue signal keeps processing latency-free and ensures no signal delays in providing a line-level, transformer-balanced output. 8.D47


CHECKING IN FOR CLEARER SPEECH Nugen Audio BY KEVIN EMMOTT


Making its IBC debut, DialogCheck is a mono, stereo and multichannel dialogue clarity meter and provides an objective measure of speech audio intelligibility in a portion of the audio clip or through an entire project. The company says that although poor speech clarity is commonly cited as a major


source of television audience complaints, engineers typically listen in acoustically specialised environments. DialogCheck provides an objective measure of speech, enabling users to evaluate their audio to identify sections of speech that might be diffi cult for listeners to understand and allowing engineers to make informed decisions about appropriate tweaks. It features more than a dozen interface tools, including an

the tracking function syncs the views with the audio playback in the DAW, while ‘Macro View’ highlights the current audio section within the wider historical view. P13 (Pods)


IBC. WebCommentator is a lightweight HTML5- based tool for remote sports event commentary. When integrated with Quantum2 AV, it enables up to two remote commentators to work from anywhere with just a web browser and an internet connection. Each commentator receives a video feed through an independent stream and has access to a dedicated


Quantum2 AV’s compact form factor replaces multiple pieces of hardware


command channel for coordination with producers or MCR technicians. The company is also introducing Cloud Codecs, a virtualised codec for large-scale audio/video stream replication and distribution. 8.C71
