Audio Software / Firmware Development Services

Intelligraphics' audio team consistently provides our customers in PC, embedded systems, and professional audio with high-quality, technically innovative driver, firmware, and low-level system software development services for their advanced audio hardware systems. Intelligraphics possesses broad development expertise in all areas of system-level audio software development combined with an extensive knowledge on a wide variety of multimedia and processing hardware.

Audio Drivers
Intelligraphics has been a preferred provider of industry-leading audio driver development services to key audio hardware manufacturers since 1995. Intelligraphics has direct experience developing audio drivers for advanced full-duplex multi-stream wave audio controllers, AC97 controllers/codecs (ICH, VIA, SIS), multifunction devices (requiring bus driver support), and Sony-Philips Digital Interface Format (S/PDIF) interfaces. It was this industry leading knowledge and capability that enabled Intelligraphics to provide the first and only WDM audio miniport for the ICH controller at the Intel plugfest that successfully passed all standby/resume tests.

Intelligraphics' audio driver development services include providing our customers with Dolby Digital (AC3), Dolby Digital Live, Dolby Master Studio, DTS, and WMA9 support for existing drivers.  Intelligraphics also retains significant expertise for providing services to support ASIO, DirectSound, and DirectMusic components as well as custom mixer applications.

WDM Drivers
Intelligraphics has extensive experience developing WDM drivers for Windows 98SE through Windows XP for a wide variety of audio accelerators. Intelligraphics can also provide expert WDM driver development for joysticks (and other HID peripherals), mass storage hardware, parallel and serial ports, USB devices, digital imaging devices and other key hardware technologies.

Universal Audio Architecture (UAA)
Intelligraphics' audio driver development experience brings with it the expertise to implement solutions based on Microsoft's new high-definition Universal Audio Architecture for Windows Longhorn. Through this new interface, Intelligraphics can help IHVs enable 24-bit 96 KHz studio quality audio processing which will be available in the next generation operating system multimedia APIs.

Audio Codecs and Filters
Intelligraphics' audio team provides the expertise to develop both software and firmware based audio codecs for AC3, DTS, WMA9, and MP3 to name a few. Intelligraphics retains considerable experience providing our customers with a variety of firmware and DSP based solutions including advanced multi-core chipsets.

Intelligraphics also offers our clients the expertise to develop telephony base audio codecs such as G723/9A and H324. Similar applications also include DirectShow and Direct Media Object (DMO) filters available in Windows XP which Intelligraphics can help ISVs integrate into custom filtergraphs or DirectSound rendering applications.

Proprietary Audio Development
While some operating systems come with full-function audio APIs, those that do not may require the development of proprietary audio APIs. Intelligraphics has direct experience developing proprietary APIs for audio subsystems and other devices to support both embedded and PC hardware. Our proprietary development services include creating essential audio operating system components such as kernel mixers, AEC and equalization filters, and software synthesizers.

Audio Operating System Support
Although Intelligraphics' current audio development focus is primarily PC Windows, Windows CE, and Linux, a significant expertise is retained for other platforms including Symbian, Palm, Nucleus and Mac OS X.  It is also known throughout the industry that Intelligraphics is the technical leader in knowledge and experience for legacy operating systems including Windows NT 4.0/3.51, Windows 95/98, Windows 3.1, and OS/2, with many innovative solutions delivered for these challenging environments.
