Opticodec-PC 1511e ~ Specifications
PERFORMANCE
Number of Audio Processors: One stereo or two independent mono audio processors, each consisting of the following cascaded processing elements: Internal Processing: Input —>Stereo Enhancer —>Two-Band defeatable AGC with window gating —>Five-Band Equalizer/HF Enhancer —>Multiband Compressor —>Look-ahead Limiter —> Automatic Loudness Controller —>Output.
Number of Channels: The 1511e 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 1511e 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.
Frequency Response: ±0.1dB, 2-20,000Hz
(Bypass software running).
Input/Output Delay: Adjustable from 25 ms to 62 ms in 1 ms steps. Presets available for one frame of: 30 fps (33.33ms), 29.97 fps (NTSC color video; 33.37ms), 25 fps (most PAL video; 40ms), and 24 fps (film; 41.67ms). "Minimum" delay is also available; this delay will vary according to the processing structure in use and crossover mode settings.
Internal Filters: 10, 11, 12, 13, 14, 15, and 20kHz can be used to provide additional anti-aliasing for low sample rate services, such as Internet Streaming Encoders, Eureka-147 (24kHz mode), iBiquity HD-AM (32kHz) and Digital Radio Mondiale.
Internal Sample Rate: 48kHz.
Wave Sample Rate: 8-96kHz.
Internal Resolution: 24-bit fixed point (3 x Freescale DSP56367).
Input/Output Resolution: 24-bit.
Peak Control Accuracy: If output samples are synchronous with internal samples, maximum overshoot of any output sample is 0.1dB. This is true at 48kHz output sample rate. If sample rate conversion after internal processing makes output samples asynchronous with internal samples, output samples can overshoot as much as 1dB (0.3dB typical).
Phase Response: All processing is linear-phase (constant group delay).
AGC (Automatic Gain Control): ±12dB/24dB gain range, Two-Band, Gate and Window enabled.
Stereo Enhancer: Two styles available: (1) Orban-patented L-R dynamic expansion triggered by L+R transients; (2) L-R delay.
Equalizers: Shelving Low Bass EQ, selectable 6 dB, 12dB or 18dB/octave. Three-band Parametric EQ with analog-style bell-shaped curves. Program Adaptive HF Enhancer.
Multiband Compressors: -24dB gain range, Five-Band and Two-Band, selectable by mute-free crossfade.
Limiter: -12dB gain range, Look-ahead IM distortion reduced, competitive with the best dedicated mastering limiters, achieving high loudness with a remarkable lack of side-effects.
Loudness Controller: 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 1511e's GUI. In dual-mono mode, there are two independent loudness controllers and meters.
Number of Factory Presets: 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" and "Look-ahead Limiter" presets.
Number of User Presets: Essentially unlimited. User presets can be saved on the host hard drive or on other storage devices.
WAVE AUDIO INPUT
Number of Inputs: 2
Configuration: Stereo
Sound Devices: 2
Driver: Multiclient Driver allows 1511e 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 Opticodec-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 1511e Opticodec-PC, requiring only one PCIe slot per program source.
Sample Rate: 8-96kHz. Asynchronously Sample Rate Converted by Driver
Sync: Internal free running or External. Either AES/EBU, Word Clock, or 10MHz input can be used as source for external sync.
Wave data will be clocked to software configurable Internal or External sources.
Input Level: Variable within the range of -20 to 0dBFS (Peak) in 0.5dB steps.
Software adjustable via Opticodec-PC Mixer Application and Windows Mixer API
WAVE AUDIO OUTPUT
Number of Outputs: 2
Configuration: Stereo
Sound Devices: 2
Driver: Multiclient Driver allows 1511e 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. Content insertion systems that would normally require two sound devices can be configured to work with one 1511e Opticodec-PC, requiring only one PCIe slot per program source.
Sample Rate: Internal free running at 32kHz, 44.1kHz, 48kHz, selected in software.
External Sync to either AES/EBU or Clock Input at 32kHz, 44.1 kHz, 48 kHz, 88.1 kHz, 96 kHz, or 10MHz, all ±4%.
Sync: Internal free running or External. Either AES/EBU, Word Clock, or 10MHz input can be used as source for External Sync.
Wave data will be clocked to software configurable Internal or External sources.

Audio Connector: DB-25, EMI suppressed.
ANALOG AUDIO OUTPUT
Note that this output is primarily for monitoring. Nevertheless, it has been designed for low noise, distortion, and overshoot and can drive an STL or transmitter in an analog facility. Peak control will not be as good as at the digital output because transmitted samples will be asynchronous with peak-controlled internal samples. Like the other Opticodec-PC outputs, the source of this output can be switched between the computer's WAVE output, the output of Opticodec-PC's Direct Mixer, Opticodec-PC's peak limiter output, and Opticodec-PC's multiband compressor output. Because most of the delay occurs in the peak limiter, using the multiband compressor output can make headphone monitoring much more comfortable for live talent when live microphone inputs are used.
Number of Outputs: 1
Configuration: Stereo.
Source Impedance: 50 ohms, electronically balanced and floating.
Load Impedance: 600 ohms or greater, balanced or unbalanced. Termination not required or recommended.
Output Level: +4dBu nominal; Clip level +18dBu unbalanced, +24dBu balanced.
Software adjustable via Opticodec-PC Mixer Application and Windows Mixer API.
Signal-to-Noise: 90dB unweighted signal-to-noise, 20Hz-20kHz (bypass mode) (Note: To prevent out-of-band noise from causing falsely high noise readings, noise and distortion specifications must be verified by a bandpass filter having a very sharp cutoff at 20 kHz.).
Distortion: <0.01% THD (bypass mode), 20Hz-20kHz. (Note: To prevent out-of-band noise from causing falsely high noise readings, noise and distortion specifications must be verified by a bandpass filter having a very sharp cutoff at 20 kHz.)
DA Conversion: 24-bit 128X oversampled D/A with linear phase anti-imaging filter.

Word Length: Selectable 24, 20, 18, or 16-bit. Optional dither can be added, with level adjusted appropriate to word length. This is first-order noise-shaped dither. (i.e., white TPDF dither of peak amplitude equal to the quantizer step size with noise shaping spectral density of 6dB/octave.) It sounds substantially quieter than white triangular PDF dither but, in contrast to more extreme noise-shaped dither, it adds only 3dB unweighted noise by comparison to white PDF dither.
