The 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.
Optimod-PC works great for both live streaming and on-demand programming. Its three on-board Freescale DSP56367 DSP chips provide a loud, consistent sound by performing stereo enhancement, automatic gain control (AGC), equalization, multiband gain control, peak-level control and subjective loudness control. Optimod-PC boasts professional AES/EBU digital inputs and outputs, plus balanced analog inputs and outputs that can operate at professional +4dBu reference levels while resisting pickup of hum and noise.
Optimod-PC's audio driver allows it to appear as two standard sound devices to the computer's operating system. With one Optimod-PC, netcasters can replace selected content (such as commercials in a program originally created for radio broadcast) and inject watermark encoding for ratings. This approach maintains the same audio processing path on both program and inserted audio, delivering a polished, consistent sound while eliminating the number one listener complaint: loud commercials.
Optimod-PC audio processing works with all digital transmission media and channels. It tailors your audio signal to help you compete in audio netcasting, HD radio (both primary and multicast digital channels), DAB, DRM and other dedicated digital radio services, FMExtra and other digital subcarriers, mastering, audio production and many others.
- Dramatically improve audio consistency dynamically with that world-renowned Optimod sound
- Most universal professional audio card with features not found anywhere else
- Prevents the top listener complaints: loudness variation and program inconsistency
- Now two sound cards in one, for professional content/commercial insertion systems and watermark encoding
- Dedicated onboard DSP saves host computer CPU cycles for more streaming encoders and ensures against audio gaps or dropouts
- Network control of audio routing, mixing and processing
- CBS loudness controller controls subjective loudness to ATSC A/85:2011 and EBU R 128 standards
- Optimod-quality digital audio processing on a PCIe sound card that pre-processes audio for consistency and loudness before it is transmitted or recorded
- 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
- Two-band automatic gain control with window gating and selectable L/R or sum/difference processing compensates for widely varying input levels
- Shelving bass equalizer and three-band parametric equalizer let you color the audio to your exact requirements
- Low-IM look-ahead limiter effectively limits peaks while ensuring that low-bit-rate codecs operate optimally without overload
- CBS Loudness Controller™ limits subjective loudness to a preset threshold
- CBS Loudness Meter™ measures the subjective loudness of the 1101e's output and is displayed in the 1101e's control application meter window
- Transparently supports dialnorm metadata in Dolby Digital® transmissions
- Allows the 1101e to perform very high quality peak limiting in mastering applications
- Optimod-PC can be used as for automatic gain control, AGC (including peak limiting) to protect a studio-to-transmitter link (STL), optimally using the STL's native dynamic range
