New Developments In Audio For Television
by David Kirk Radio does remarkably well for itself without pictures. On the other hand, television without sound would be a very restrictive medium. Video puts the performance in perspective but audio usually delivers the actual story. So what is new in the audio for television arena? The following is a trawl made from IBC.
Calrec Audio’s Artemis Light is the newest member of its Artemis family of Bluefin2/Hydra2 audio consoles. Artemis Light introduces a new compact processing rack dedicated to delivering DSP and routing capabilities in a 4 RU enclosure. Up to 240 input channels can be assigned as mono, stereo or surround paths. Up to 16 main outputs and 48 audio groups can be assigned as mono, stereo or surround from a pool of 72 buses, as well as 48 track and 24 auxiliary output buses. The integral router has 8 x Hydra2 ports for interfacing with the extensive Hydra2 I/O range, as well as other Hydra2 routers and their I/O. declick algorithm (Manual Declick ‘B’) the introduction of reporting and improvements to existing modules including Retouch, DNS, NR-4 and NR-5, the Adaptive Limiter and Vintage Decrackle. The introduction of cue points and regions allows users to attach text to the audio and to set up multiple regions for rendering. Cue data can be saved in the metadata chunks of WAV files, allowing them to be transferred between Cedar Cambridge systems and other workstations that recognise those chunks. Other improvements include a spectrogram view to augment the existing waveform view, improved transport controls, improved channel mapping, the ability to perform transparent sample rate conversion while saving files, and the introduction of user-definable Hot Keys which allow operators to control the system from their keyboard and from devices such as foot-pedals that map to the key commands. This intended for users (particularly in the field of audio forensics) who need to listen repeatedly to short snippets of audio.

Cedar Audio
Cedar Audio’s Cambridge V7 sound processor incorporates a new module (Respeed), a new

and 4-wire interconnections. The 1 RU base station supports up to 16 full-duplex and 44 half-duplex belt packs and/or wireless headsets by linking four base stations. The DX210 is paired with the BP210 beltpack and All-in-One WH210 Wireless Headset communication units. The system is backward compatible with DX200 models such as the BP200, WH200 and WS200. The HME DX210 has a digital auto-nulling circuit which allows

digital audio inputs and is supplied with ITU, EBU and ATSC loudness measurement recommendations, as well as the standard DKTechnologies meter scales.

Aero.calm
Linear Acoustic’s Aero.calm controls loudness and dynamic range without affecting original content. A hybrid of multiband audio analysis and metadata control, it passes audio through

Clear-Com
Clear-Com’s HME DX210 is a newly-designed twochannel intercom system that has advanced the capabilities of the existing DX200. The DX210’s wired intercom interface is now compatible with Clear-Com’s or RTS’ 2-wire systems, and provides two separate 2-wire

users to eliminate the return audio of the wired 2-wire intercom automatically. The system offers 2-wire circuit protection to prevent feedback from unterminated 2-wire channels. The DX210 also has an assignable auxiliary input for programme.

DK Meter
DK Technology’s DK Meter allows stereo and Dolby 5.1 metering, including loudness. It accepts

untouched if compliant. Any required processing is performed in a consumer-reversible manner (permanently for non-critical material), allowing individual viewers the choice of hearing the full range of the original content if they desire. Versions of Aero.calm are available to handle baseband AES/SDI audio, DVB-ASI, and transport stream over IP.
