RML Labs Software Audio Console v1.2

SAC is the acronym for Software Audio Console. This program runs in Microsoft Windows and turns your Windows PC into a powerful virtual Live Mixing Console.

SAC opens new realms of live sound mixing capabilities with virtual mixing technology built around a core hand coded assembly language engine. The look and feel of a fully controllable Front Of House (FOH) console, coupled with 24 duplicate monitor mixing consoles with digital split points from 5 locations within the FOH Input Channels and 2 locations within the FOH Return Channels, creates a whole new way of mixing live sound while eliminating and replacing racks of physical equipment, snake cabling and splitters.

> The FOH Console
The virtual console is designed as a 72 input channel, 72 output channel FOH console, with Input Source, Attenuator, Phase Reverse, Swap L/R, and Mono buttons, 5 Band Stereo EQ with additional Hi and Lo Cut filters, Keying Gate and Compressor with bandpass filter, Pre and Post FX patch points, 6 Stereo Aux Sends with Pan, 24 Stereo Output Assigns, 8 point XY Surround Pan with separate Sub and Center Chan, Solo, Mute, Stereo Pan, long throw Fader with a Stereo Hi Resolution (-60 dB) Meter on each channel.
Any input channel may be assigned to any or all output channels at the same time. 8 Master Output channels may be routed to any hardware output device while the remaining 16 Output channels can be used as subgroup, VCA type Faders, folding back to any of the 8 Master Faders. The Aux Sends may be internally routed as virtual or patched out to any device output, and returned from any device input, in sync, direct into the FOH mix, through 6 independent Return channels, each with complete FX patching capabilities and their own Hi Resolution Meters.
XY Surround panning is built in and can be assigned in any manner to up to 6 discreet outputs. The surround setup can be saved in templates making 5.1, 7.1, quad surround or any configuration available at the touch of the mouse. The console can be displayed in different views, independently or simultaneously, allowing quick access to multiple perspectives of the current information.
The console has extensive navigation capabilities and is intimately linked to the different views. There are popup navigation menus that display labeled channels and track references, allowing instant one-click access to anywhere you need to go.

> The Monitor Consoles
The FOH console inputs internally split to 24 monitor consoles, giving essentially duplicate versions of all FOH console views and allowing you to mix monitors from master faders instead of Aux Sends or Matrix knobs. This allows each monitor mix to be its own 72 channel stereo mix with its own overlayed Eq and Dynamics sections, as well as its own 6 stereo Aux Sends and Returns. Each Monitor console has 8 Master Stereo Output Channels, leaving 16 channels to be used as subgroups. The input splits can be taken from the FOH Src, Pst EQ, Pst Dyn, Pre Fader or Post Fader. Additionally, Monitor Mixer 1 can be designated as a master monitor mixer and all remaining monitor mixers can take their splits from it. Each monitor console and individual input channel can use any one of those split points independently of every other channel, opening up a brand new dimension in monitor mixing routing and control.

> The Engine
The underlying architecture is an entirely new – from the ground up – virtual mixing engine, based on many years of experience with the development and maturity of the SAW product line.
The focus of this new engine design is centered around the live, low latency input driven technology that forces the engine to sense and trigger precisely from live input data stream timing. This engine ssembles the data, LIVE, on the fly, directly in front of the actual data being played out by the sound devices, delivering instant reaction time and the feel of a physical console, without glitching the audio data.
The engine makes extensive use of multi-processor and priority multi-threaded code design, and with its hand coded assembly language techniques, is capable of reaching performance levels not thought possible
within the standard Windows environments. The design uses advanced assembly language techniques to emulate all functions of the console portion of the program. Faders, Eq, Dynamics, Aux Sends and Returns, Meters, Echo/Delay, Reverb, etc. are all emulated DSP routines, that rival the performance of hardware based units when used on high-end computers. This design also eliminates the need for special DSP based hardware sound devices, allowing standard audio sound cards access to all of the design features.
The new engine design allows for most every program operation to be performed live, while the engine is
running, without the need to stop the data stream to change device assignments, input and output routing
or save sessions and manipulate Scene and Sequence data.
Because of the low latency capabilities, this engine is a perfect match for external fader packs and mixer controllers. SAC uses a complete virtual lookup table design to link incoming controller signals to virtual console and transport controls, and other internal functions of the engine. Different hardware controller information can be stored in templates (without the need to update or rewrite the program code) that can be instantly loaded into the program to change from one controller type to another, without the need to restart the program! Templates are available for a wide variety of the most popular controllers, and future templates will be made available for download, as new hardware is released.

> FX Processing
A brand new powerful SAC API (Application Programming Interface) has been developed for handling FX Plug -Ins. This interface offers one of the most direct and streamlined protocols for passing information between the application and processing plug-ins. This design also offers enhanced power and control, including automation capability, while actually increasing overall efficiency. The API is compatibile with most Native SAWStudio plugins.
The DirectX and VST protocols are seamlessly woven into the engine design, with all plug-ins of all types showing in one common effects choice window. With the current availability of numerous DirectX and VST plug-ins to choose from, you can begin FX processing immediately without waiting for future development.
Effects are hot-patchable, meaning they can be plugged in and out in real-time during playback! The engine will automatically initialize and insert the plug-in directly into the audio loop in perfect sync, without the need to stop the stream.

> TCP/IP Remote Network Access
SAC also includes an extensive internal networking engine that allows up to 28 remote users to access the system via standard TCP/IP network connections. You can use a simple ethernet cable and hub or switcher, or a wireless system to allow complete freedom to roam the venue and control everything from a remote laptop. A set of user stats can control the access rights of anyone connected to the host system.
You can connect as a FOH engineer, which gives you access to FOH and all 24 Monitor consoles. You can also connect as a MON engineer, which gives you access to only the 24 Monitor consoles. A final tier allows a PERsonal connection to just 1 Monitor console, which opens the door for any performer onstage to have complete control of his, and only his, complete Monitor console.

Its time to let SAC change the way you work with live audio forever. Welcome to the dawn of a new era of Live Sound Mixing!
