The OPTIMOD-PCn 1600 is Orban’s solution for server-based audio processing. It complements our well-known hardware processor product portfolio and is the perfect choice for customers who need a flexible and scalable audio processing solution. The number of audio processors can be selected according to your requirements. A selection of factory presets will help you to find the perfect sound for your application.
Whether you need audio processing for live streaming Internet, DAB/DAB+, HD radio or TV broadcasts, OPTIMOD-PCn 1600 will do the job. Its architecture provides a consistent, well-produced sound to the consumer by performing phase skew correction, stereo enhancement, intelligent automatic gain control (AGC), equalization, multiband gain control, peak-level control, and smart automatic loudness control. It runs as a Windows Service on its host computer, so it will start automatically with Windows and run reliably in the background.
The setup, metering, and subjective loudness control incorporate contemporary concepts of “target loudness” including those specified in EBU R128 and ATSC A/85 and in the most recent ITU-R BS.1770 loudness measurement algorithm as well as the proprietary third-generation Orban-CBS Labs Loudness Meter and Loudness Controller, that are based on the seminal work of Jones & Torick and CBS Laboratories.
OPTIMOD-PCn 1600 supports audio-over-IP via any standard such as AES67, SMPTE-2110, RAVENNA and Dante given the appropriate I/O hardware and drivers.
The PCn 1600 configuration is done easily using the supplied Windows PC user control application. Via the user interface you can control all your audio processing streams in your connection list.
OPTIMOD-PCn 1600 - Key Features
You will need to purchase one OPTIMOD PCn1600 license for each instance of audio processing required. Theoretically, you can run an unlimited number of instances on your PC, it is only limited by the available CPU power. The main factors determining how much CPU a given instance will use are:
the number of channels of processing (dual-mono or stereo),
whether the MX Peak Limiter is activated, and
whether the Loudness Controllers are enabled.
The PCn1600 is the perfect solution for Internet, DAB/DAB+, HD Radio and other dedicated digital radio services as well as sound-for-picture, mastering, audio production, and many others. It can be also used as a server-based multi-stream pre-processor for existing hardware OPTIMOD processors, adding features like parallel compression and the “Multipath Mitigator” phase corrector.
OPTIMOD PCn1600 provides modern “target loudness” concepts including those specified in EBU R128 and ATSC A/85 using the ITU-R BS.1770 loudness model. It allows you to easily set and verify the target loudness of the output. You can also use the proprietary Orban-CBS Labs Loudness Meter and Loudness Controller that provides BS.1770 compliance better than a BS.1770-based loudness control and it does so without audible gain pumping or other annoying artifacts common in BS.1770-based loudness controls.
Orban’s exclusive PreCode technology 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 pre-processed by other processing than OPTIMOD.
An easy-to-use graphic control application runs on local or remote Windows PCs and can control any number of OPTIMOD PCn1600 instances. Each audio processor can be protected from unauthorized access with a user and an administrator password.
