THX is the trade name of a high-fidelity sound reproduction system for movie theatres,home theaters,computer speakers,gaming consoles,and car audio systems.THX was developed by Tomlinson Holman at Lucasfilm in 1983 to ensure that the soundtrack for the third Star Wars film.Return of the Jedi,would be accurately reproduced in the best venues.The THX system is not a recording technology,and it does not specify a sound recording format;all digital (Dolby Digital,SDDS) and all analog sound formats (Dolby SR,Ultra-Stereo) can be “shown in THX.”THX is mainly a quality assurance system.If a producer has their film mixed in THX,it merely means that when the film is shown in theaters,the soundtrack will sound exactly as it did when it was mixed,if the theatres are THX-certified.

The process of writing data to a recordable CD can be a complex process, as it demands a lot from both hardware and software programs. Much of this complexity is hidden from the user by the program, although you should be aware of these factors. Data The total amount of data you are writing is much less important than whether or not it contains large or several small files. If there are a lot of small files, the system may have problems with locating and opening the files quickly enough to send them smoothly to the CD recording drive. The computer Any interruption that may occur is fatal to CD duplication, so you should ensure that your CONFIG.SYS and AUTOEXEC.BAT don’t load any TSR utilities which may interrupt operations. Screen savers, alarms and reminders, or incoming faxes may also kill disc writing. You should also turn off network sharing so no one will access the files that you are trying to write, as this could also kill your disc recording. Hard Disk Speed To write an image to the CD, the hard disk from which you are writing must have a transfer rate that is fast enough to keep the memory buffer full in the CD recorder. This normally means an average hard disk access time of 19 MS or better. Defrag If your hard drive has to search everywhere over a fragmented hard drive for the data to be written, it can cause the operation to slow down or even cause a fatal error. Therefore, always be sure to fragment your hard disk drive. Recording speed Most new CD recorders and even some older ones, are capable of writing at two (sometimes even four) times the standard playback. It should be possible for you to select the speed; as even though fast recording is a time saver, it can also cause some bad situations. When you copy an ISO (image file) from the hard disk to a CD, the speed is rarely a problem as the image is already one large file in which the files and structures are already in order and divided into CD-ROM sectors. When you write from a virtual image, things can get a bit trickier. In order to copy to CD, the program must consult with the database to find where each file should go in the image and where it is actually stored on the hard disk drive. Then, it must open the file, divide it into CD-ROM sectors, at the same time sending the data in a smooth continuous stream to the recorder. Locating and opening the file is a bit more time consuming, as writing is more difficult if you have a lot of small files.

As use of the Internet continues to grow geometrically, we see an increased demand for information to be provided by a variety of media. Viewing options can range from simple text to PDF documents to video clips. Unfortunately, each option requires more and more resources and technological know-how. As convergence moves inexorably forward, we have to ask ourselves if there is a practical way to combine the best of this technology and still provide the user with a satisfying Internet experience.

The answer, at this stage of Internet evolution, is audio.

Voice, by itself, provides the means to enhance a user’s enjoyment of the Internet. Voice conveys many of the intangibles underlying the written word. A voice can touch the human spirit and deliver a message on its’ own merits. Audio can build community and maintain relationships.

Audio is the most mature of the streaming technologies and doesn’t have the bandwidth requirements associated with video. Any Internet user connecting at 28.8k or better can enjoy FM quality sound without experiencing buffering and other annoyances that can affect video at lower bit rates.

It is common knowledge that people only retain 20% of what they read, but they do remember 70% of what they see and hear. That fact in itself increases the value of an audio message delivered from a website for the typical user. And, the implications of how audio can increase Internet enjoyment for the handicapped are overwhelming.

Streaming audio provides Internet businesses with unlimited opportunities to reach their audience and to simplify their interactions. Streaming audio broadens a product’s appeal and helps to stimulate sales. People are comfortable with audio and have few qualms about using it in their day-to-day lives.

Retailers can integrate audio into their operations in several ways. Use it to enhance product descriptions and deliver product information in ways far more persuasive than plain text. Booksellers can have “special events” that offer audio excerpts from selected titles. Art dealers can use voice to give value added information on an artist or a period of history depicted by an artist’s work. (Think of those audio tours that museums offer.)

Organizations that specialize in selling educational tools can use audio clips for potential clients to preview and evaluate the material being offered. The ability to sample the product is a potent and practical selling aid.

Business-to-Business sites and corporate Intranets can also harness the power of audio. The need to provide up-to-the-minute information for employees and customers can be well served with streaming audio and the telephone. Integrating audio into the corporate communications mix is a tool that is easy to use and addresses the need to communicate with a distributed work force.

In both the retail and business-to-business marketplace, audio can and should be used to maintain those all important customer relationships. Voice messages add a personal touch that intrigues the listener and encourages them to remain on the site.

Employee training is greatly enhanced with audio. Use it to orient new employees and keep the information archived on the site for easy reference. Sales training can also be archived and quickly retrieved when needed. The ability to offer customized audio training materials on a 24/7 basis makes streaming audio a very versatile and efficient learning tool.

Some words of caution are also necessary. Audio, just like any other value-added technology, has to be used judiciously. It should be employed for a specific purpose and to enhance the text based message being delivered. Think of your audience and how you’d like them to interact with your website. Keep in mind that your visitor may be coming to your site while they’re at their place of business and plan accordingly.

The future of streaming audio is bright and filled with promise. More and more Internet users have become familiar with streaming audio and use it everyday. Internet radio broadcasts are extremely popular and are now being employed as effective advertising vehicles. Audio e-mail messaging is becoming widely available and is being positioned as a practical business tool. Consumers are attaching audio messages to greeting cards and experimenting with Internet telephony. Streaming audio will allow the average Internet user the ability to create content that conveys the power of voice and the emotions that it conveys.

So…why aren’t you using audio?
