  • 24 Bit 96 Khz Digital Audio Workstation Using High Performance Be Operating System on a Multiprocessor Intel Machine
    24 bit 96 kHz Digital Audio Workstation using high performance Be Operating System on a multiprocessor Intel machine by: Michal Jurewicz - Mytek, Inc., New York, NY, USA Timothy Self - Be, Inc., Menlo Park, CA, USA ABSTRACT Digital Audio Workstation (DAW) has quickly established itself as the most important digital audio production tool. With the advent of high-resolution multi-channel audio formats and Internet audio exchange, the high performance and flawless operations of the desktop DAW have become a necessity. The authors explaining why current popular computer architectures are not suited to these new tasks, explore the possibilities of the new Be Operating System (BeOS)- specifically designed and optimized to handle digital audio and video. New features, unattainable with current operating systems, are discussed. 1. Introduction Ever increasing performance of computers has caused a gradual migration of the key audio production tools from hardware embodiments to the virtual world of computers. This trend will continue, propelled by bottom line economics and the appearance of new features such as network audio exchange. Although current computer hardware is up to the task, existing general purpose operating systems are the actual performance bottleneck . Designed over 10 years ago for general purpose computing, they fail to meet increasing demands for speed and file size. The new BeOS has been designed from ground up to handle high bandwidth digital audio and video in a modern multiprocessing and multitasking environment. The paper focuses solely on the use of commodity personal computers (IBM Compatibles and Apple) and their operating systems (Windows, MacOS, BeOS and Linux). Although number of specialized platforms such as SGI provides superior performance, they were omitted, as their presence in the current professional audio environment is minimal.

  • So What's the A6 Computer from STD Really Like?
    Front cover and reprint by kind permission of Qercus magazine. So what's the A6 computer from STD really like? (A reprint from Qercus issue 268) The A6 What is the A6? The A6 is a new generation of RISC OS computer. It is based around a high-specification PC running Windows XP. An emulation environment called VirtualRPC enables this machine to appear to RISC OS as if it is a traditional RiscPC machine, and so normal RISC OS applications can be run. Can I run all RiscPC applications? Virtually all, yes. The exception are those which rely on direct access to the parallel or serial ports such as the dongled versions of Impression, although the non-dongled versions work fine, and some modem diallers - internet connections are provided by the emulation environment via the internal modem or network interface. How fast? The A6 will generally run user applications much more quickly than the fastest StrongARM RiscPC. Applications which rely on the transfer of large amounts of data, such as DTP or graphics manipulaton will perform faster still. Such applications also benefit from 8MB of "VVRAM", which means that large screenmodes in true colour are no problem. Our new A6+ offers further enhancements and even better performance - see the last page of this leaflet for details. You're biased! Yes, we are - we specified the A6 to offer an ideal RISC OS emulation environment and we're proud of our achievements. But don't take our word for it - enclosed is a copy of a review of the A6 computer which originally appeared in Qercus issue 268.

I answered him directly via email but I thought everyone would be interested in my answer here: Hi Tony, Regarding your post on BeOS: tony espinoza ([email protected]) "...i'm considering a Radar 24 system for my studio... only one question is nagging at me. living in the bay area, i know folks that have worked long and hard on the BeOS. but since Palm recently acquired the company, everyone I know associated with BeOS has either been let go or has split. i can see palm keeping a couple DTS guys around doing support on the OS, but knowing their financial situation (and management situation), i can't see them committing resources to it for very long without significant returns. i certainly can't see key features that iZ might be interested in continue to be the focus of the OS..." None of our development so far depends on any support from Be Inc or Palm. Those companies probably don't even know we exist. If we got updates on the OS we'd be nervous about sending it out since we now have over 2 years of stable track record with it.

  • Dualbooting Amigaos 4 and Amigaos 3.5/3.9
    Dualbooting AmigaOS 4 and AmigaOS 3.5/3.9 By Christoph Gutjahr. Licensed under the GNU Free Documentation License This tutorial explains how to turn a classic Amiga into a dualboot system that lets you choose the desired operating system - AmigaOS 4 or AmigaOS 3.5/3.9 - at every cold start. A "cold start" happens when... 1. the computer has just been switched on 2. you press the key combination Control-Amiga-Amiga for more than ten seconds while running AmigaOS 3 3. you press Control-Alt-Alt (instead of Control-Amiga-Amiga) under AmigaOS 4 During a "warm reboot" (e.g. by shortly pressing Control-Amiga-Amiga), the operating system that is currently used will be booted again. Requirements This tutorial is only useful for people using AmigaOS 3.5 or 3.9 in addition to AmigaOS 4. If you're using an older version of OS 3, you can not use the scripts described below. The Amiga in question should have two boot partitions - one for AmigaOS 4 and one for AmigaOS 3.5/3.9, both should be below the famous 4 GB barrier. The OS 4 partition must have a higher boot priority. Two different solutions There are two different approaches for dualbooting: the first one described below will display a simple 'boot menu' at every cold boot, asking the user to select the OS he wants to boot. The other solution explained afterwards will always boot into AmigaOS 4, unless the user enters the "Early Startup Menu" and selects the OS 3 partition as the boot drive.
