Operating Systems (OS) are made up of collections of small pieces of software designed to perform various tasks. Provides a graphical user interface (GUI) to make launching applications, organising files and controlling the hardware easier.
Files (save, retrieve) data and programs and keep a directory of their location on attached storage devices. Drivers (for example) are installed onto the hard drive into the System folder whenever a new piece of hardware is added to the system (such as a MIDI interfaces, soundcard's, scanners, modems, printers etc).
As well as recording audio from multiple sources, Audacity also comes with a full set of editing features. The popularity of Personal Digital Assistants (PDAs) is growing rapidly with the advent of more powerful devices and wider range of available applications. The study begins with a short view to the history of PDAs, after which situation today is analyzed by examining different aspects of the devices. The goal of this study is to examine and analyze the market, architecture, and capabilities of Personal Digital Assistants (PDAs) as well as their abilities to support mobile multimedia.
It seems, that the term PDA is more or less a synonym for a number of other marketing terms including hand-held devices, wearable computers, palmtops, pocket computers, smart-phones, pagers, internet appliances, to name a few. Small computers have been around since 1980’s when companies like Casio, Sharp, and Tandon produced first models that people were able to take with them on the road. Before the commercialization of PDAs a number of prototypes and similar devices had been built in the academic world. Around year 1996 the PDA market was in chaos with dozens of vendors each pushing forward their proprietary machines and operating systems. Game console manufacturers have also been interested in adding PDAs to their product portfolios. Microsoft tried to push its early versions of Windows CE operating system as the standard for PDAs, but failed in the effort.
Some of the leading manufacturers of PDAs today include Motorola, Hewlett-Packard, 3Com, Nec, Casio, Fujitsu, Sharp, Psion, and Philips. International Data Corporation has estimated that the worldwide smart handheld devices market will continue to boom in 1999.
Wireless Internet access is implemented directly typically only in Smart phones like Nokia Communicator, Ericsson MC-12, or Qualcomm pdQ. Though the CPU is less of a buying factor for PDAs, some more expensive models have faster RISC processors than cheaper models. Many PDA devices run on standard AA or AAA alkaline batteries, while newer models sometimes include AC power and rechargeable NiMH or lithium-ion battery packs.
Most of the PDAs on the market are currently using either PalmOS or Windows CE operating systems. The latest Windows CE operating system is version 2.1, nick-named Wyvern, which supports color and audio.
As the architectural introduction showed, today's PDAs are not properly equipped for mobile multimedia. This chapter presents technical specifications of some devices currently on the PDA market. Major developments are not expected to the input methods, although some companies will offer different input solutions such as foldable or wireless keyboards as add-ons for their products. When computing power and memory increases, some level of support of voice recognition is also likely to appear.
Audio will develop first through Windows CE platform, which has built-in support for advanced audio capabilities. World will, at least initially, continue to be divided into different connection solutions. Printing through wireless connection will probably be supported more and more in the new generation of PDAs. PDA power solutions depends on the general research and development of the battery technology. Probably the most awaited introduction in the field of operating systems will come from Symbian as they introduce the EPOC operating system and its newer versions. PDAs have been on the market for around six years, during which time their capabilities have improved and prices have gone down. All in all current PDAs do not allow proper mobile multimedia usage, but the situation may change dramatically within a few years or even months' time.

For example, QuickTime system drivers, extensions and codecs to enable a huge range of image and video file formats to be recognised and displayed by suitable applications (including the QuickTime player application itself).
These are small graphical units (like logos) designed to allow the user to keep track of all the hardware components of the system (such as disk drives and printers) together with all stored applications and data. The mouse allows intuitive interaction with the GUI and operation of applications and manipulation of data and documents.
Using the Mouse a user can select GUI and application specific menu’s generally situated along the top of the screen in order to carry out tasks. At their heart they have a System file (or collection of files) which are augmented by a number of other category elements such as shared code libaries, fonts and drivers.
It is the drivers job to communicate between the hardware and the OS, and therefore all applications which may need to use the hardware. Audacity can record live audio through a microphone or mixer, or digitize recordings from cassette tapes, records, or minidiscs.


You can use it to edit your sound files using Cut, Copy and Paste (with unlimited Undo), mix tracks together and apply effects to your recordings. PDAs are being applied to many different tasks including personal information management, communications, information seeking, entertainment, location dependent services, and eCommerce. Finally the study presents some likely PDA developments in the near future and their meaning to the mobile multimedia on PDAs.
The seminar was held at the Helsinki University of Technology during the spring 1999 with the emphasis on multimedia and mobility. The outcome should give a picture of today’s PDA market as well as to characterize some likely developments of the PDAs in the near future.
They see the PDA as "a productivity and communications tool that is lightweight, durable, reliable, easy to use, and integrates into existing operations." They state that PDAs typically can be held in one hand leaving the other to input data with a pen type stylus or a reduced size keyboard.
These machines had typically few kilobytes of memory and contained a basic interpreter for user programs. Apple launched Newton MessagePad in 1993, after which several other manufacturers introduced similar products.
Some of the systems offered connectivity to PCs or Macs, but in general network access or multimedia capabilities were a rarity.
Nintendo has developed GameBoy, which currently ships with a color display and has limited capabilities to run other applications. Larger PDAs typically use a stylus for navigation and a keyboard for data input, although some models offer handwriting-recognition as an add-on option. PDA displays have traditionally been back lit gray-scaled touch-sensitive units with rather a low resolution, typically 160*200. Even if the device can play digital samples, the sound quality is normally poor do to the size of the speaker(s).
These units are dependent on the cellular network capabilities and provide access to network at low speeds like 9.6kbps.
Typical processors include Motorola DragonBall, NEC VR411X (Casio, Everex, NEC), and Hitachi RISC series (HP, Casio).
Monochrome PDAs run with their batteries around 12 hours and up, with 3Com claiming weeks of operation for the Palm III. 3COM has released PalmOS specifications as well as development packages, which has led to a wide selection of available software. Windows CE is designed to be modular, which means, that it can be configured for usage in a variety of different environments. Although some functionality can be implemented, most applications would require higher resolution, more colours, and larger displays to be useful. If mobile on-line usage is possible, current network standards limit the communication down to around 9.6 kbps thus making streaming multimedia usage quite difficult. PDAs have currently too little RAM memory to store any larger multimedia material in the devices. PDA processors today do not yet pose the computing power required to decently process animations, sounds, and other components of multimedia material.
This is quite far away from the stereo high-quality, possibly 3D sound that is available for multimedia on other platforms. If resolution is raised, more colours are used, mass memory or network is accessed, or audio is utilized, standard power supplies in the units are likely to drain out in a very short time.
These devices represent some form factors and technical designs the PDAs and handhelds have today. The information presented in this chapter should be taken only as suggestive, not as ultimate facts about the upcoming architectural developments of PDAs.
Casio uses in its E-100 a new type of TFT LCD display that is capable of producing 320*200 in 16-bit colors. In addition, mass media devices like miniature hard-discs will be incorporated in the units.
Current record speeds of 133 MHz (NEC VR4112) will not held for long, but 133MHz will probably be the standard for the new devices for the rest in 1999. Rechargeable power sources based on Lithium-Ion technology will be the dominant solution for the 1999, after which some more advanced method will probably take its place. The Windows CE platform will probably stay quite the same for at least the following months due to the recent introduction of new version.
This study defines PDAs through their key functionality, which are handheld size, mobility, the ability to communicate with other units, and some possibly expandable set of applications.
The most important of these reasons are shortage of RAM memory, lack of mass media devices, size and resolution of displays, network connectivity either missing or too slow for streaming usage, and the lack of computing power.

With great prices, fast shipping, and top-rated customer service - once you know, you Newegg. For example; when you print a letter from a word processing application the OS passes the data to the printer. On power up the user is confronted by a simulation of an office desktop on which are placed icons representing some of the connected hardware, such as the hard drive and printer. Audacity also has a built-in amplitude envelope editor, a customizable spectrogram mode and a frequency analysis window for audio analysis applications.
The main emphasis is in the current market and multimedia capabilities, although a brief history and a peek into the future are also included in the report. Some of the more advanced PDAs can also react to basic voice input by using voice recognition technologies. However, we are able to derive the key characteristics of PDAs by taking the presented definitions above and combining them with some observations of the appliances. They did not qualify for business usage not to mention any mobile multimedia purposes, but pawed the way for more advanced successors. The Newton was technologically advanced, featuring handwriting recognition, a modem for Internet access, and even an infrared port, for which, however, there did not exist any practical usage at that time.
This was understandable, as suitable data transfer standards were not in place and the devices lacked memory, processing speed, and proper displays to support multimedia applications. Sony has developed some sort of PDA to be used together with their Playstation game console.7 In spite of the effort, however, console manufacturers have not been able to extend their customer base to the PDA market.
In 1998, the most popular PDA manufacturer worldwide was 3COM with its PalmPilot models commanding 41.4 percent market share.


Color display has been a rarity due to higher costs, lack of operating system support, and higher electricity consumption.
Many PDAs include also slots for memory cards or miniature hard-disks such as Mini-Cartridge and CompactFlash. These processors have usually 32 bit architecture and operate at speed between 50 and 133 MHz. Color models consume more electricity shorting the operational time down to around three to six hours. Just try to take notes by writing them on a PDA and you’ll see how long you are able to follow the presenter.
This is a direct implication of the QWERTY keyboard model, which simply contains too many keys.
One solution could be incorporating PDAs with miniature mass media devices like the recently introduced PDA hard disk from IBM. This is changing with the introduction of Windows CE 2.1, in which both sampling of audio and its playback is supported.
As one can see, larger handheld-sized units come with more features, but with a price; their size and weight is very close to the smallest laptops on the market today. In a few months time the 640*480 resolution will be available at approximately 4 inch screen size, which means, that from that moment on it is possible to produce basic VGA -level screens on palmtops. 3COM is likely to continue the development of PalmOS, but there will quite unlikely be any major modifications in the operating system due to backward compatibility reasons. From this set we exclude PC-based appliances and units, that cannot conveniently fit into one’s palm or do not boot instantly. And if you have sound files already on your computer but you would like to combine with other files or new recordings, you can import those files into your Audacity project. Some of the built-in audio effects include Bass Boost, Wahwah, Equalization, Noise Removal and Normalize, Vocal Remover as well as support for VST plug-in effects. The paper does not try to cover every aspect of electronic appliances or computers, but instead defines the term PDA and concentrates on issues relevant to that definition.
Those characteristics are handheld size, mobility, the ability to communicate with other units, and some possibly expandable set of applications. Even though there was a clear need for MessagePad in the market, it was not a huge commercial success.
Even though some manufacturers have developed ways to fold the keyboard into smaller space (see e.g.
These units are, however, currently so new and expensive that it will take some time before they are incorporated into standard versions of PDAs. An example of these new processors is NEC VR4112, which gives the PDAs enough computing power to play MP3 audio files and video streams.
Typically PDAs running Windows CE 2.1 contain a monaural speaker and a plug for external earphones.
The most important changes will be support for wireless communication in the United States and support for color displays. Display devices are improving so that in the near future we can have more colors and higher resolution without changing the display size. Die tatsA¤chliche Versandzeit kann in EinzelfA¤llen, insbesondere zu Spitzenzeiten, abweichen.
It is capable of importing sound files in many formats including WAV, AIFF, MP3, and OGG files. In addition to the definition, the purpose of the study is to summarize and categorize the major architectural choices available in the PDA market today presenting some of the PDA alternatives as examples. By defining a PDA through its key features we avoid the pitfall of excluding some relevant appliances from this study because in a strict sense those units are not marketed as PDAs.
This was due to its high price, size, limited applications, slowness and somewhat disoriented marketing strategy.4 Apple launched a number of different Newton models between 1993-1997 until it withdrew from the PDA market in 1997. PalmPilot –series of PDAs offered pen-based input like Newton but in a much smaller and faster package.
For example, 3Com’s Graffiti is well known for its accuracy but requires the user to learn a new writing style. However, together with the introduction of the Windows CE 2.0 the operating system this obstacle has been removed and a number of color-display models have been introduced. Software-based modems are becoming more common with faster professors, because they lower hardware costs and increase battery life.
The access speed will grow first in 1999 to 14,4 kbps, after which more advanced methods like GPRS, Blue tooth and UMTS will replace the current speeds with much higher communication speeds allowing also multimedia streaming over the network.
The former will be included in the PalmPilot version VII and the latter introduced in the model code-named Razor.
To keep the number of alternatives manageable, however, we will have to exclude some alternatives from this analysis even thought some of the applicable devices might quite well be included.
One exception to the handwriting-recognition rule is the Texas Instruments Avigo10, which uses virtual on-screen keyboards that come in both standard QWERTY and Tegic’s T9 flavor. The best of the breed today is to have around 9" SVGA TFT display with a support to external monitors. As PDAs at least today use some proprietary architecture and dedicated operating system, PC-based computers are not included in the report. Computer connectivity was handled with a small synchronization cradle or alternatively via a modem connection.
T9 groups letters in triads, guessing which letter you intend to select upon the touch of the stylus. These devices require quite a lot of space and thus do not necessary fit to our definition of the PDAs.
The same goes with other portable devices; if the system does not come on immediately or the size is substantially larger than what one could fit in a one palm, the unit is not included.
