Orban OPTIMOD-PC 1101e Audio Processing Card

The Orban Optimod-PC 1101e professional Microsoft Windows audio processing card for PCIe bus systems offers dedicated, broadcast-quality digital signal processing on-board for audio processing, mixing, and routing. Optimod-PC processing is more reliable than software-based processors that run native on the computer's CPU because the operating system can never starve Optimod-PC's processor or mixer for processing cycles. This allows more instances of an encoding application to run glitch-free on the computer's CPU, which provides higher reliability and lower operating costs because fewer CPUs are required for large operations.

Drivers are now available for 32 and 64-bit versions of Windows XP, Vista, 7, 8.1, and 10.

Key Features:

  • Optimod-quality digital audio processing on a PCIe sound card that pre-processes audio for consistency and loudness before it is transmitted or recorded.
  • Applications include netcasting, HD Radio® (both primary and secondary digital channels), DAB and other dedicated digital radio services, FMExtra™ and other digital subcarriers, mastering, audio production, and many others.
  • Orban's 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 preprocessed by other processing than Optimod.
  • Two-Band automatic gain control with window gating and selectable L/R or sum/difference processing compensates for widely varying input levels.
  • Balanced analog input with 24-bit A/D converter is always active, mixing with the two digital inputs.
  • Balanced analog monitor output with 24-bit D/A converter.
  • Digital inputs accept any sample rate from 32 to 96 kHz without manual configuration.
  • I/O Mixer application permits 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.
