One stereo or two independent mono audio processors, each consisting of the following cascaded processing elements: Internal Processing: Input -> Stereo Enhancer Û Two-Band defeatable AGC with window gating -> Five-Band Equalizer/HF Enhancer -> Multiband Compressor -> Look-ahead Limiter -> Automatic Loudness Controller -> Output.

The 1101 audio driver allows it to appear as two standard sound devices to the computer operating system. Each of the two sound devices can handle one stereo channel or two mono channels. The channels can be mixed and routed via a three-bus mixer (“Processed”, “Direct 1” and “Direct 2”), however the 1101 can only apply stereo or dual-mono audio processing to the output of the “Processed” bus. The remaining two “Direct” busses are applied to the Output Routing Switcher but cannot be further processed. See block diagram.

±0.1 dB, 2 – 20,000 Hz.

Adjustable from 25 ms to 62 ms in 1 ms steps. Presets available for one frame of: 30 fps (33.33 ms), 29.97 fps (NTSC color video; 33.37 ms), 25 fps (most PAL video; 40 ms) and 24 fps (film; 41.67 ms). “Minimum” delay is also available; this delay will vary according to the processing structure in use and crossover mode settings.

10, 11, 12, 13, 14, 15 and 20 kHz can be used to provide additional anti-aliasing for low sample rate services, such as Internet Streaming Encoders, Eureka-147 (24 kHz mode), iBiquity® HD AM™ (IBOC) (32 kHz) and Digital Radio Mondiale.

Constrains subjective loudness to a user-adjustable threshold via the 1981 Jones & Torick CBS Technology Center algorithm as further refined and developed by Orban. The algorithm also drives a subjective loudness meter, which is displayed on the 1101’s GUI. In dual-mono mode, there are two independent loudness controllers and meters.

More than 20, each with 19-step LESS-MORE control. Presets are fully customizable with FULL CONTROL. In addition to presets for full processing, there are also “AGC”, “Look-ahead Limiter” and “mastering” presets. There are also presets for analog television that uses an FM aural carrier.

Essentially unlimited. User presets can be saved on the host hard drive or on other storage devices.

Multi-client Driver allows 1101 to appear as two standard sound devices to the computer operating system. The input can therefore be received from multiple software applications running on the host computer system by use of standard operating system sound device driver calls. For example, this could include single or multiple player applications, such as an audio playout system with multiple players, content insertion system, or audio over IP routed into the host computer through an Ethernet port, and/or multiple streaming audio encoders. Because the driver is multiclient, it allows it to source multiple applications simultaneously. A versatile mixer and router application allows you to mix digital, analog, and wave inputs to three busses (one with OPTIMOD-PC processing and two without) and to route the outputs of the “Processed” and “Direct” busses to the Analog, Digital, and Wave Outputs in any configuration or combination, such that any output can receive any bus or the unprocessed Wave Input. Content insertion systems that would normally require two sound devices can be configured to work with one 1101 OPTIMOD-PC, requiring only one PCI or PCIe slot per program source.

Multi-client Driver allows 1101 to appear as two standard sound devices to the computer operating system. The output can therefore be routed to multiple software applications simultaneously, such as audio encoders, recorders, and content insertion systems running on the host system, and/or the card physical outputs via the Mixer Application. Software applications running on the host system do not require the use of physical cables to connect Wave Inputs and Outputs to applications, eliminating any unnecessary digital sample rate conversion.

Mixer application provides complete control of digital mixer and all hardware settings.

The control application provides subjective adjustment controls of the audio processing and remote administration. It also allows factory and user presets to be recalled from and save to a host storage device such as a hard disk drive or removable drive. The control application client addresses multiple OPTIMOD-PC cards, either housed in the local host or anywhere on a TCP/IP network or by local serial communication. The control application also functions as a server, interfacing cards installed in a given host computer with the network for control and monitoring.

Microsoft Windows Mixer Control API is supported for Input and Output switching and levels. This provides compatibility with Windows applications that use standard Microsoft Windows Mixer calls and enumeration.

The IP API provides complete remote administration over TCP/IP. The OPTIMOD-PC Service application hosts a TCP/IP Terminal Server to allow external control of the OPTIMOD-PC cards from either a Telnet/SSH client or a custom third party application. All OPTIMOD-PC Presets and Mixer Controls are accessible and all commands are simple text strings. Telnet/SSH: RFC 318 compliant basic subset. Compatible with Windows Telnet and PuTTY Telnet clients. TCP/IP Port user assignable.
