    Conventional AM, FM, or TV audio processors that employ pre-emphasis/de- emphasis and/or clipping peak limiters do not work well with perceptual audio cod- ers such as Orban’s Opticodec-PC® MPEG4 AAC/aacPlusV2 streaming encoder. The pre-emphasis/de-emphasis limiting in these processors unnecessarily limits high fre- quency headroom.

    It is equally suitable for netcasts and digi- tal radio or television broadcasting. With its supplied WAVE drivers, it looks like a standard sound card to your native applications, like the Orban’s Opticodec-PC® MPEG4 AAC/aacPlusV2 streaming encoder. However, unlike a sound card, OPTIMOD-...

    In digital radio applications, if you wish to place level protection prior to your stu- dio/transmitter link (STL), use an Orban studio AGC like the Orban 8200ST. The 8200ST can be adjusted so that it substitutes for the broadband AGC circuitry in OPTIMOD-PC, which is then defeated.

These inputs and outputs are controlled by the OPTIMOD-PC Mixer appli- cation, which can be launched from the Tools menu on the OPTIMOD-PC control application, and can also be remotely accessed.

  • Page 32: Analog Left/Right Input/Output

    The outputs are intended for monitoring. They can drive 600Ω or higher imped- ances. However, they are AC-coupled with a –3dB frequency of approximately 1 Hz, which is higher than the 0.15 Hz recommended by Orban to avoid low-frequency overshoots (“bounce”) caused by phase shifts. Therefore, when you are using the...

    OPTIMOD-PC is supported on Windows XP (SP2 or higher) and on Vista (SP1 or higher) computers. It will usually work on Windows 2000 computers (SP4 or higher) but Orban Customer Service does not support this platform. No other operating sys- tems (such as Linux or Mac OS) will work.

One instance of the server application handles communications for all of the OPTIMOD-PC cards in a given host computer.

  • Page 39: Location Of Optimod-Pc For Netcasting

    It is usually best to locate OPTIMOD-PC cards in the same machine that runs the en- coding software, like Orban OPTICODEC-PC, Microsoft Windows Media Encoder or Real Networks HELIX Producer. This is because the output of the encoder is at a much lower data rate than the audio used to drive the OPTIMOD-PC input(s), so it is less expensive to transport encoded audio than unencoded audio.

  • Page 41: Transmission From Studio To Transmitter

    1-23 OPTIMOD-PC INTRODUCTION Most netcasters will not find the information in this section relevant because if net- casters need to ship audio beyond their LAN, they ordinarily ship it from one loca- tion to another in the form of encoded audio through low-capacity Telco-supplied digital links like ISDN or E-1/T-1.
  • Page 42 1-24 INTRODUCTION ORBAN MODEL 1101 should leave “headroom” in the algorithm so that OPTIMOD-PC’s multiband proc- essing will not unmask quantization noise. This is also true of any lossy data reduc- tion applied in the studio (such as hard disk digital delivery systems).

  • Page 43: Microwave Stls

    STL is good enough to pass un- processed audio. The signal-to-noise ratio of the STL can be used optimally if an Orban Studio AGC, another OPTIMOD-PC, or an Orban Transmission Limiter protects the link from overload.

  • Page 44: Analog Telephone/Landline (Ptt/Post Office Line)

    STLs have this problem. Some consultants presently offer modifications to minimize or eliminate this prob- lem. If your exciter or STL has this problem, you may contact Orban Customer Service for the latest information on such services. Analog Telephone/Landline (PTT/Post Office Line) Analog landline quality is extremely variable, ranging from excellent to poor.

  • Page 45: Optimod-Pc At The Transmitter: Gain Control Before The Stl

    Further, many STLs require level control to prevent the STL from being overloaded. To apply such level control and compression, we recommend an Orban AGC/Limiter/HF Limiter (like another Optimod-PC or an Orban 6300 stand-alone mul- tipurpose processor or an OPTIMOD-PC) before the STL transmitter.

  • Page 46: Using Lossy Data Reduction In The Audio Chain Before Optimod

    1-28 INTRODUCTION ORBAN MODEL 1101 Using Lossy Data Reduction in the Audio Chain before OPTIMOD-PC Many broadcasters and netcasters are now using lossy data reduction algorithms like MPEG-1 Layer 2 to increase the storage time of digital playback media. In addition, source material is often supplied through a lossy data reduction algorithm, whether from satellite or over landlines.

  • Page 47: Subframe Delay

    1-29 OPTIMOD-PC INTRODUCTION OPTIMOD-PC’s bandwidth can be adjusted from 10 kHz to 20 kHz to provide cor- rectly anti-aliased audio for any of these systems. If any anti-aliasing filters following OPTIMOD-PC’s output are phase-linear and have integer-sample time delays, these filters will pass the band-limited OPTIMOD-PC output without introducing overshoot because they remove no further spectrum and do not cause their output samples to become asynchronous with the peak-controlled samples at OPTIMOD-PC’s output.

  • Page 48: Monitoring On Loudspeakers And Headphones

    OPTIMOD-PC’s processing has a second output after the multiband compressor but before the look-ahead peak limiter, which is where the majority of the delay occurs. This output feeds one of the inputs to the output routing switcher in the Orban I/O Mixer application.

  • Page 49: Streaming And Netcasting Applications

    One of the outputs of OPTIMOD-PC’s routing switcher sends audio back into the computer’s internal WAVE audio system. You will ordinarily connect this stream to the input of an encoder application, like Orban OPTICODEC-PC, RealNetworks Real/Helix Producer, or Microsoft Windows Media Encoder running on the same host as OPTIMOD-PC.

    OPTICODEC-PC PE is designed to work exclusively with OPTIMOD-PC to form an overall audio processing / coding chain with the highest audio quality possible for a given bitrate. These two components are also available from Orban as part of a turnkey system called OPTICODEC-PC Encoder, which includes a rack mount Win- dows XP computer with both components pre-installed and pre-configured.

    In processing, there is a direct trade-off between loudness and distortion. You can improve one only at the expense of one or both of the other two. Thanks to Orban’s psychoacoustically optimized designs, this is less true of Orban processors than of any others.

To exploit PreCode technology fully, do not set up OPTIMOD-PC for very bright sound (with large amounts of high frequency energy) because this is likely to exacerbate codec artifacts.

  • Page 102: Optimod-Pc In Radio-Oriented Applications: From Bach To Rock

    Professional netcasters committed to providing their audiences with the best audio possible at a given bitrate should consider the use of a higher performance codec like Orban’s Opticodec-PC, which uses standards- based MPEG-4 AAC/HE-AAC/aacPlus™. HE-AAC is the most efficient codec available at the time of this writing.

    OPTIMOD-PC OPERATION Never lose sight of the fact that, while the listener can easily control loudness, he or she cannot make a distorted signal clean again. If such excessive processing is per- mitted to audibly degrade the sound of the original program material, the signal is irrevocably contaminated and the original quality can never be recovered.

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). By operating only on transients, the 222 increases width, brightness, and punch without unnaturally increasing reverb (which is usually predominantly in the L–R channel).
