Avenue 9670 Audio Automatic Gain and Loudness Control and 9690 Audio Compliance and Monitoring Software

The LevelTrack™ Audio AGC option adds a user configurable audio level management system to Avenue signal processing modules. LevelTrack AGC corrects mismatched
audio levels between different program sources or segments within a program. Errors of this type are regrettably common due to inconsistencies between different providers and program elements.

1770 and VU Loudness Algorithms

LevelTrack AGC provides two different approaches for adjusting audio levels: VU algorithms and the ITU-R1770 loudness algorithm. LevelTrack allows you to run your audio against a 1770 LKFS target range. These loudness measurements and adjustments conform to the ITU-R1770 specification. Loudness is frequency dependent and is weighed based upon case studies that reveal how humans perceive sound and loudness. Dialnorm™ values correspond to 1770 algorithms and contribute to compliance requirements. Alternately, VU algorithms may be used where audio levels are weighted with VU metering and measured in dBFS. The VU approach is particularly useful when calibrating and aligning equipment because it is a frequency independent method.

Parameters and Control

Range controls are provided for target level, spread, transition time, silence limit, and maximum gain and attenuation. This flexibility allows the operator to customize
LevelTrack to suit the specific audio level challenges in a particular installation. All of these parameters can be easily adjusted through the Avenue Control System.

LevelTrack adjusts the levels for up to 16 audio channels. Based upon the history in each channel, gradual changes are applied to prevent the audio level from dropping
below or exceeding user programmable thresholds. This automatic level control can be applied on an individual channel, stereo pair, or 5.1 surround grouping. By adjusting the overall level of the signal, rather than masking the errors with compression, LevelTrack does not upset the internal dynamics of the program material.

LevelTrack operates downstream of the manual audio level adjustments that are already provided in Avenue modules. This allows the automatic feature to assist the operator when needed by simply enabling the channel or grouping.

BrightEye 90 HD Up/Down Cross Converter and ARC with AES AudioBrightEye 90 is a versatile up/down/cross converter or aspect ratio converter for use with analog and digital video signals. Simply set the BrightEye 90 to output your facility’s preferred or SD standard. The BrightEye 90 will accommodate whatever input you connect – analog composite, SD SDI or HD SDI. After setting the output standard, BrightEye 90 automatically converts the selected input to the correct standard for your facility. BrightEye 90 will upconvert, downconvert, cross convert, or act as an ARC, as needed. The built-in Frame Synchronizer allows you to feed asynchronous signals to the BrightEye 90. An external reference input allows genlock to a house reference. All vertical interval data and closed captioning is faithfully passed. Upconverting to High Definition Feed the analog composite or SD SDI output of a camera to a BrightEye 90 and upconvert to HD. You can take the HD signal from the BrightEye 90 into a switcher or projection system. Upconverting existing SD equipment lets you leverage the equipment you already have and operate in the HD domain. While some cameras may have firewire out, using the video output and upconverting before distribution is preferable since longer cable runs can be achieved and quality is superior. Additionally, the BrightEye 90’s reference input allows you to time the upconverted video output for use with a production switcher. Downconverting to Standard Definition BrightEye 90 will downconvert any type of HD signal and provides both an SD SDI and an analog composite output suitable for broadcast or monitoring. Cross Conversion It’s easy to convert between various HD standards, whether 720p or 1080i. Simply select the output standard you need and connect the input, that’s all there is to it. Aspect Ratio Conversion For converting between SD 4:3 and HD 16:9, BrightEye 90 has you covered. Just select the output standard you need and connect the input. Audio Processing Made Simple BrightEye 90 handles both embedded audio and discreet AES digital audio streams. Sixteen channels of embedded audio are supported in BrightEye 90. If the incoming video has embedded audio, the audio will be safely bypassed around the video processing and lipsync will be preserved. Audio mixing is available for two of the four embedded groups of audio. The AES I/O ports can be configured for eight channels of incoming audio or for eight channels of audio output. The audio mixer can be used for AES channels as well. Mixer controls are accessed through the BrightEye Control app. Monitoring for Video and Audio Audio monitoring is easy with BrightEye 90’s convenient 3.5mm mini jack. Select the audio channels you want to monitor from the front panel and plug in a headset. The HDMI connector on the rear of the unit provides a future proof monitoring interface. Plug it into most LCD monitors for confidence monitoring of your feed. Front Panel and Software Control Input selection, gain control, and test pattern controls are provided through the front panel interface. Audio presence LEDs indicate which channels are detected. Controls for crop, letterbox and pillarbox are accessed from the front panel or BrightEye Mac or PC software. Video and audio levels and the audio mixer can be adjusted through BrightEye Control.
