From the ground up, Optimod-PC 1101 was designed for professionals. It has broadcast-quality digital signal processing on-board that’s suitable for both live streaming and on-demand programming. OPTIMOD-PC’s three on-board Freescale DSP56367 DSP chips provide a loud, consistent sound to the consumer by performing stereo enhancement, automatic gain control (AGC), equalization, multiband gain control, peak-level control, and subjective loudness control. Moreover, Optimod-PC is equipped with balanced analog inputs and outputs that can operate at professional +4dBu reference levels while resisting pickup of hum and noise.

Optimod-PC is available in two versions-the 1101 is for PCI bus systems and the 1101e is for PCIe (PCI Express). Optimod-PC’s audio driver allows it to appear as two standard sound devices to the computer’s operating system. This allows netcasters who need to replace selected content (such as commercials in a program originally created for radio broadcast) to do so with only one sound card.

Optimod-PC audio processing is appropriate for 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. Additionally, video-oriented presets use Optimod-PC’s built-in CBS Loudness Controller to make Optimod-PC an unsurpassed choice for mono or stereo sound-for-picture applications, including HDTV, DVB-x digital television, and audio/video netcasting.

While primarily oriented toward “flat” media, Optimod-PC can also provide preemphasis limiting for the two standard preemphasis curves of 50μ and 75μ. This allows it to protect preemphasized analog satellite uplinks and similar channels where protection limiting or light processing is required, and makes it ideal for use as a studio AGC driving transmitter-located Optimods.

Without Optimod-PC processing, audio can sound dull, thin, or inconsistent in any combination. Optimod-PC’s multiband processing automatically levels and re-equalizes its input to the “major-market” standards expected by the mass audience. It also helps overcome background noise in mobile listening environments.

Broadcasters have known for decades that this polished, produced sound attracts and holds listeners and Orban has long been the number one vendor of stand-alone transmission processing to professional broadcasters worldwide. Commercial broadcasters think nothing of spending upwards of $10,000 to sculpt their audio with an Optimod! Audio processing can help create an audio environment or mood. A broadcaster’s revenue depends on audience share, and broadcasters know that compromising their processing is false economy.

Professional radio broadcasters would never consider going on the air without audio signal processing. They consider it a vital aspect of their program content. This carefully crafted content is what holds listeners and keeps them coming back. Since 1975, Optimod algorithms have dominated the world market for professional radio and television audio processing and have been improved continuously since then. OPTIMOD-PC puts this technology inside your computer.

Features

There are many gain/peak control devices and software available to perform dynamics processing. Many of these tools are designed for recording studio applications as effects compressors/limiters for individual microphone or instrument tracks. These devices’ controls need to be tuned carefully for the specific material being processed-they are not “set and forget” processors. Moreover, most do not process mixed program material without introducing objectionable audible artifacts, particularly when called upon to gain-ride input material having widely varying levels.

A broadcast audio processor should ideally be “seen, but not heard.” Optimod processing algorithms simultaneously control audio gain and peaks, artistically, musically, and naturally, to give the illusion that processing is not taking place. Moreover, Optimod algorithms intelligently adapt themselves to the input program material. Once OPTIMOD-PC is tuned for the sound texture required for the broadcast or netcast format (which is made easy by OPTIMOD-PC’s many format-specific presets), it will provide excellent consistency regardless of the level or texture of the original program material. OPTIMOD-PC’s automatic gain control and equalization achieve a consistent sound, while accurate peak control maximizes loudness. Booming bass is tightened; weak, thin bass is brought up; highs are always present and consistent in level.

Thanks to Optimod-PC, a netcaster who wants to maximize audience share no longer has to make do with toy processing, ineffective CPU-hungry plug-ins, and inappropriate recording studio plug-ins. Optimod-PC offers full broadcast-quality Optimod processing on a card-an economical, space-saving alternative to conventional stand-alone boxes. But thanks to its tight integration into the PC, Optimod-PC offers more features than any stand-alone processor. Among others, these include two digital inputs with mixing of asynchronous sources, two digital outputs, and sound card emulation that allows Optimod-PC to talk through the operating system to applications running on the host.

For optimum sound, loudness, and peak control, you should digitally preprocess an Internet audio signal to condition it prior to encoding. The appropriate preprocessing has much in common with the preprocessing required for DAB, HD Radio, CD mastering, or digital satellite.

Professional-grade netcasting requires audio processing similar to FM broadcast (although there are some important differences in the peak limiting because of the different characteristics of the pre-emphasized FM channel and the perceptually coded netcasting channel). Your listeners deserve to get the best quality and consistency you can provide. Good audio processing is one important thing that separates the amateur from the professional.

Conventional AM, FM, or TV audio processors that employ pre-emphasis/de-emphasis and/or clipping peak limiters do not work well with perceptual audio coders such as Orban Opticodec-PC® MPEG-4 AAC/HE-AACv2 streaming encoder. The pre-emphasis/de-emphasis limiting in these processors unnecessarily limits high frequency headroom. Further, their clipping limiters create high frequency components-distortion-that the perceptual audio coders would otherwise not encode. None of these devices has the full set of audio and control features found in Optimod-PC.

Peak clipping sounds bad even in uncompressed digital channels because these channels do not rely on pre-emphasis/de-emphasis to reduce audible distortion. Instead of peak clipping, OPTIMOD-PC uses look-ahead limiting to protect the following channel from peak overload.

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. There are several factory presets tuned specifically for low performance, low bitrate codecs.

Unlike some other codec preprocessors that produce audible consequences, PreCode does not suck the punch and life out of music. Instead, PreCode strikes an artistic balance between liveliness and artifact reduction, ensuring that the cure is never worse than the disease.

Optimod-PC is also an excellent mastering processor, offering soft knee multiband compression with knee and ratio controls available separately for each band. This is followed by a low-IM look-ahead limiter that can typically achieve 12 dB of gain reduction before it produces objectionable artifacts-this limiter is exceptionally loud and clean.

Digital mixing is crucially important to a netcaster who needs to control commercial content and insertion. Unlike most sound cards, Optimod-PC allows you to mix an analog source, two digital sources, and two Wave sources. For example, you could run a playout system on your computer while using the three hardware inputs for a live microphone feed, commercial insert, and network insert. Or you could run the commercial insert playout software on the same computer as the main playout system, using Optimod-PC’s second Wave input to separately route the outputs of the two playout systems to the card. In most cases, an external mixer isn’t needed, making Optimod-PC a more economical system solution than a low-priced sound card combined with a bunch of external hardware. This is also perfect for podcast production.

For applications like commercial insertion, an API provides complete remote administration over TCP/IP and/or Serial. The Optimod-PC Service application hosts a TCP/IP terminal server, and Serial interface to allow external control of the Optimod-PC cards from either a software Telnet/SSH terminal client, a custom third party application, or hardware device, such as a Broadcast Tools SRC-16. All Optimod-PC Mixer and System Controls are accessible and all commands are simple text strings. You can adjust and monitor levels, tweak the processor’s sound, save and recall presets, and more. Password security is provided.

Optimod-PC comes with over 20 great-sounding presets that make it easy to create a sonic texture that’s just right for your target audience. If you want to customize a preset, you can start with an easy LESS-MORE control, and, if that’s not enough, tweak over 50 parameters to hone your sound to perfection. Optimod-PC’s deep interface will never hold you back as your processing expertise increases, yet its carefully crafted design insulates you from the details if you need great sound right now.

You can expect a considerable increase in loudness from Optimod-PC processing by comparison to unprocessed audio (except for audio from recently mastered CDs, which are often overprocessed in mastering). Broadcasters generally believe that loudness relative to other stations attracts an audience that perceives the station as being more powerful than its competition. We expect that the same subliminal psychology will hold in netcasting too.

It is important to understand that peak or average file normalization does not accomplish what OPTIMOD-PC processing can. Normalization applies a fixed loudness adjustment to the entire file. It’s like setting a volume control once and only once. On the other hand, OPTIMOD-PC processing constantly adjusts spectral balance and loudness to achieve a consistency that brands your sound. This particularly important during transitions from one program element to the next and is one of the key techniques that major-market radio stations use to achieve their polished, “produced” audio texture.

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).

Stereo Enhancer: Two styles available: (1) Orban-patented L-R dynamic expansion triggered by L+R transients; (2) L-R delay.

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 1101’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.

Number of Inputs: 2

Configuration: Stereo

Sound Devices: 2

Driver: Multiclient 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.

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.

Number of Outputs: 2

Configuration: Stereo

Sound Devices: 2

Driver: Multiclient 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. 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.

Sample Rate: Internal free running at 32kHz, 44.1kHz, 48kHz, selected in software.

Nominal Input Level: -10dBu / +4dBu VU, -2dBu / +21dBu PPM.

Maximum Input Level: +24 dBu, peak.

Reference Level: -20dBFS. -10dBu / +4dBu VU Input Level produces -20dBFS when Input Level fader is 0dB.

A-D Conversion: 24-bit 128X oversampled delta sigma A/D converter with linear phase anti-aliasing filter.

Audio Connector: DB-25, EMI suppressed.

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 OPTIMOD-PC outputs, the source of this output can be switched between the computer’s WAVE output, the output of OPTIMOD-PC’s Direct Mixer, OPTIMOD-PC’s peak limiter output, and OPTIMOD-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.

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.

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.)

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.
