Product Description

Optimod-PC 1101 ~ Features

  • Optimod-quality digital audio processingÿon a PCI sound card that pre-processes audio for consistency and loudness before it is transmitted or recorded.
  • Available in two versions:ÿ1101ÿforÿPCIÿsockets andÿ1101eÿforÿPCIeÿ(PCI Express) sockets.
  • Applicationsÿinclude netcasting, HD Radio?ÿ(both primary and secondary digital channels), DAB and other dedicated digital radio services, FMExtra?ÿand other digital subcarriers, mastering, audio production, and many others.
  • SuppliedÿWAVE driversÿallow Optimod-PC's processed output to pass through the PCI bus to the CPU, driving standard PC applications like Orban's Opticodec-PC MPEG-4 HE-AAC, Microsoft, or Real streaming encoders. Optimod-PC's audio driver allows it to appear asÿtwo sound devicesÿto the computer's operating system. The driver (with the aid of concurrently running third-party software) also allows Optimod-PC to receiveÿaudio over IPÿfrom the host computer's network connection. Drivers are available for 32 and 64-bit Windows XP,ÿ32 and 64-bit Windows Vista, and 32 and 64-bit Windows 7.
  • Orban'sÿPreCode?ÿtechnology manipulates several aspects of the audio to minimize artifacts caused by low bitrate codecs, ensuring consistent loudness and texture from one source to the next. PreCode includes special audio band detection algorithms that are energy and spectrum aware. This can improve codec performance on some codecs by reducing audio processing induced codec artifacts, even with program material that has been preprocessed by other processing than Optimod.
  • Two-Bandÿautomatic gain controlÿwith window gating and selectable L/R or sum/difference processing compensates for widely varying input levels.
  • Shelvingÿbass equalizerÿand three-bandÿparametric equalizerÿlet you color the audio to your exact requirements.
  • Low-IM look-ahead limiterÿeffectively limits peaks while ensuring that low-bit-rate codecs operate optimally without overload.
  • Precisely controls peak levelsÿto prevent overmodulation or codec overload. The peak limiter can be set up to control "flat" transmission channels or channels preemphasized at 50?s or 75?s.
  • Whileÿprimarily oriented toward "flat" media, Optimod-PC can also provideÿpreemphasis limitingfor the two standard preemphasis curves of 50?s and 75?s. This allows it to protect preemphasizedÿsatellite uplinks and similar channelsÿwhere protection limiting or light processing is required.
    • Because its processing topology is most effective with "flat media," Optimod-PC cannot provide extreme loudness for preemphasized radio channels. Use one of Orban's Optimod-FM processors for this application. For analog television with FM aural carrier(s), use Optimod-TV 8382.
  • Optimod-PC'sÿdual-monoÿarchitecture allows entirely separate mono programs to be processed in 5-band mode, facilitating dual-language operation.
    • In this mode, both processing channels operate using the same processing parameters (like release time); you cannot adjust the two channels to provide different processing textures.
  • Balanced analog inputÿwith 24-bit A/D converter is always active, mixing with the two digital inputs.
  • Balanced analog monitor outputÿwith 24-bit D/A converter.
  • Two AES3 or SPDIF digital inputsÿwith high-quality sample rate conversion allow two asynchronous digital sources to be mixed: Ideal for network operations using local commercial/announcement insertion.
  • Theÿsecond digital inputÿalso accepts AES3 house sync, synchronizing the AES3 output sample rate to the sample rate of the sync input.
  • Digital inputsÿaccept any sample rateÿfrom 32 to 96 kHz without manual configuration.
  • Two AES3 digital outputsÿat 32, 44.1, 48, 88.2, or 96 kHz sample rate. In v1.0 software, these emit identical signals.
  • Two Wave inputsÿfrom any PC audio application (like a playout system) that can emit standard Wave audio. Audio from the Wave inputs can be mixed and switched with Optimod-PC's hardware inputs. Because there are two inputs, you can operate two PC applications simultaneously and mix and/or switch their Wave outputs inside Optimod-PC, such as content/commercial insertion systems.
  • Two Wave outputsÿto any PC audio application that can record or encode.
  • Optimod-PCÿcontrols the audio bandwidthÿas necessary to accommodate the transmitted sample frequency, obviating the need for extra, overshooting anti-aliasing filters in downstream equipment. Optimod-PC's high frequency bandwidth can be switched instantly (typically in 1 kHz increments) between 10.0 kHz and 20 kHz. 20 kHz is used for highest-quality systems. 15 kHz meets the requirements of the iBiquity?ÿHD-AM system that use 44.1 kHz system input sample frequency. (15 kHz codec bandwidth may also help low bitrate lossy codecs sound better than they do when fed full 20 kHz bandwidth audio.) 10 kHz bandwidth meets the requirements of auxiliary DAB transmissions using a 24 kHz sample frequency.
  • Internal processing occurs atÿ48 kHzÿsample rate andÿ20 kHzÿaudio bandwidth.
  • Full PCI bus-masteringÿwith optimization.
  • I/O Mixer applicationÿpermits versatile routing and switching of processed and unprocessed audio from and to Optimod-PC's inputs and outputs, and to and from the host computer's WAVE audio.
  • Terminal Control APIÿfor network or localhost control and automation of all I/O Mixer functions and Preset switching. Status is broadcast to all active clients.
  • Serial Control APIÿallows Optimod-PC to be controlled either by ASCII serial commands or by a serial-to-contact-closure device such as a Broadcast Tools SRC-16.
  • MS Windows Mixer APIÿsupport in parallel to the existing Orban Mixer allows standard Microsoft Windows audio applications to control Optimod PC's inputs and outputs.
  • MS Windows Metering APIÿso Windows applications using this API will display audio levels. (Many broadcast playout systems use this.)
  • Freescale DSPsÿdo all the audio processing?there is no extra DSP load on your computer's CPU, allowing more CPU for encoding of bit-reduced audio.
  • Fullÿcoprocessingÿ(independent of the host computer's CPU) means that audio will ordinarily continue to pass through the card from its hardware inputs to its hardware outputs even if the host computer crashes. (Of course, Wave inputs and outputs will stop working because these are dependent on operating system services.)
  • Optimod-PC ships with overÿtwenty standard presets, which correspond to different programming formats. These presets have already been tested and field-proven in major-market radio netcasting, digital radio, and direct satellite broadcasting applications (both radio and television) worldwide. There are also special-purpose presets for studio AGC, pure peak limiting, and low bitrate encoding applications.
  • An easy-to-useÿgraphic control applicationÿruns on your PC and can act as a client to control any number of Optimod-PC cards, either locally or in other PCs on your network via TCP/IP. The Orban software offers a server function, allowing other computers on your network to address cards located in your PC. (This server software is installed automatically as part of the Optimod-PC installation process and runs as a Windows Service.)
  • The Control application allows you complete flexibility to createÿyour own custom presets, to save as many as you want to your local hard drive, and to recall them at will.

Adaptability through Multiple Audio Processing Structures

  • Aÿprocessing structureÿis a program that operates as a complete audio processing system. Only one processing structure can be active at a time. Just as there are many possible ways of configuring a processing system using analog components (such as equalizers, compressors, limiters, and clippers), there are many possible processing structures achievable by Optimod-PC. Optimod-PC realizes its processing structures as a series of high-speed mathematical computations made by Digital Signal Processing (DSP) chips.
  • Optimod-PC features two processing structures:ÿFive-Bandÿ(or Multiband) for a consistent, "processed" sound, free from undesirable side effects andÿTwo-Bandÿfor a tastefully controlled sound that preserves the frequency balance of the original program material.
  • The Two-Band structure can also be tuned to operate as aÿProtection Limiter, providing up to 25dB of safety limiting with minimal side effects.
  • Optimod-PCÿcan increase the density and loudnessÿof the program material by multiband compression and look-ahead limiting, improving the consistency of the station's sound and increasing loudness and definition remarkably, without producing unpleasant side effects.
  • Optimod-PCÿrides gainÿover an adjustable range of up to 25dB, compressing dynamic range and compensating for operator gain-riding errors and for gain inconsistencies in automated systems.
  • Optimod-PC's processing structures are allÿphase-linearÿto maximize audible transparency.
  • Optimod-PC can be changed from one processing structure to another with aÿsmooth cross-fade.
  • The 1101 provides two differentÿstereo enhancementÿalgorithms. The first is based on Orban's patented analog 222 Stereo Enhancer, which increases the energy in the stereo difference signal (L-R) whenever a transient is detected in the stereo sum signal (L+R). The second stereo enhancement algorithm passes the L-R signal through a delay line and adds this decorrelated signal to the unenhanced L-R signal. Gating circuitry prevents over-enhancement and undesired enhancement on slightly unbalanced mono material.
  • Two-Bandÿautomatic gain controlÿwith window gating and selectable L/R or sum/difference processing compensates for widely varying input levels.
  • Shelvingÿbass equalizerÿand three-bandÿparametric equalizerÿlet you color the audio to your exact requirements.
  • Two-bandÿandÿfive-band compressorsÿwithÿparametric soft-knee compression curvesÿallow you toÿfine-tune the audio to your exact requirementsÿand make Optimod-PC an excellentmastering processor.
  • The output of the two-band or five-band compressor can be routed directly to the card's outputs, facilitating creation of aÿlow-delay monitoring path for talent headphones.
  • Low-IM look-ahead limiterÿeffectively limits peaks while ensuring that low-bit-rate codecs operate optimally without overload.
  • CBS Loudness Controller?ÿlimits subjective loudness to a preset thresholdÿ, making the 1101 anÿideal processor in sound-for-picture applicationsÿbyÿtaming loud commercialsÿbefore they annoy and alienate the audience. The Loudness Controller uses the 1981 Jones & Torick algorithm developed at CBS Technology Center and further refined by Orban. This processing fully complies with the loudness control requirements in ATSC A/85:2011 and EBU R 128.
  • CBS Loudness Meter?ÿmeasures the subjective loudness of the 1101's outputÿand is displayed in the 1101's control application meter window. Inÿdual-mono mode, there areÿtwo independent loudness controllersÿandÿtwo loudness metersÿavailable.
  • Transparently supports dialnorm metadata in Dolby Digital?ÿtransmissions:ÿIf you tell the 1101 the dialnorm level you are sending to receivers and use a "TV" processing preset, your transmission will automatically have the same loudness as other properly aligned Dolby Digital sources. This makes the 1101 an excellent choice to process ATSC subchannels.
  • A pure peak limiting preset is available. It allows the 1101 to performÿvery high quality peak limiting in mastering applications.
  • Optimod-PC can be used as for automatic gain control,ÿAGCÿ(including peak limiting) to protect a studio-to-transmitter link (STL), optimally using the STL's native dynamic range.
