1.Thou shall create audio products as the fastest way to come out with a product.

Forget about e-books. They take to long to create especially if you’re a slooooow typist. You can create an audio product in a day instead of weeks or months with an e-book. If you must create an e-book, do the audio first and have someone transcribe the audio into a word file. You than clean it up and add some chapter heads and an index and Bam! You have an instant e-book

2.Thou shall use a headset microphone for your recordings.

I find that using a headset mic is a lot more versatile than a standard microphone. A headset mic gives you the freedom to move your head around and you don’t feel restricted as far as being positioned in front of a table top mic.

3.Thou shall not be afraid to record your voice.

Many people hate the way they sound on tape (me included) and feel that they cannot put together a “Professional” product. The first time you hear yourself on tape you are just going to die. It takes practice to actually speak properly. You get struck by the dreaded Uh and Um syndrome and the monotone voice virus but take heart …you can do this. Slow down and concentrate on what you’re saying and interject some emphasis and pitch changes to your voice. Bottom line…add some personality.

I’ll admit I’m no professional speaker myself… It takes practice and you will get better.

Here are a couple books you might want to check out: The Quick and Easy Way to Effective Speaking by Dale Carnegie Secrets of Successful Speakers: How You Can Motivate, Captivate, and Persuade by Lilly Walters

4.Thou shall add intro and outro music to your audios

If you really want to add a professional polish to your products you must add the intro and outro music. You know that cool music you hear at the beginning of the audio just before someone starts the introduction.

You could give this site a try: frontandbackmusic.com for some demos.

5.Thou shall use different formats for your audio info product

A couple of ways to create an audio product is to interview someone over the phone and record it or just do a straight forward gab session on your own. To keep it simple when I’m recording on my own, I write down some bullet points to use as memory joggers to keep me on track during the recording sessions. Also, when using the computer software it allows you to pause so you can get your thoughts together and then just restart the recording process without a skip.

6.Thou shall use different listening formats for your audio product.

When distributing your audios you have different formats to choose from. You can use .wav, .mp3, .ram files. Wave files take up the most space and are megabyte hogs. Mp3 and ram (real player files) take up the least amount of space and are good for streaming audio on the web. If you are distributing your audio on CD it is best to use wav. That way you will be able to listen to them in any CD player. Here is a little warning when recording your audio projects. Be aware of the space you have on your hard drive. A two hour recording session will take up to 1.3 gigabytes of space in wav. I like to record and edit in smaller intervals and burn them to a CD-RW just to get them off my hard drive.

7.Thou shall use cheap resources for your audio.

I get all my bubble pack shippers and CD cases off of Ebay. They have some great deals. I get my CD’s duplicated at Diskfaktory.com because they can run small quantities of 50. I wouldn’t get any more made until you know you have a winner.

8.Thou shall have fun when creating your audio products

I have to say I really enjoy the creation process and it’s really neat when you go to record a product and can play it back and listen to it on the fly. You get a sense that this thing is really coming together. And when you add the music you really get a sense of satisfaction. Creating audio is really instant gratification when it comes to creating info products. I love it…

As of this writing, I’m working with my wife on a product and I’m interviewing her and we are having a blast. She makes mistakes and I make them and we just sit there and laugh. My wife has the UH and UM syndrome so we are trying to get cured of that… But the point is that we are having a good time.

Quick Tip: I use a splitter to add two microphones to my computer. You need to raise the volume to get it normalized.

9.Thou shall build a audio information empire

If you really want to get a jump start in the information product business this is the easiest and funniest way to do it. As fast as you can record and edit these things the faster you can crank them out and start making some money. Also audio CD and tapes have a higher perceived value and you can get more for them then by just selling an e-book.

10.Thou shall learn what software to use for your audios.

Software can be expensive. Many of the gurus recommend Sounforge but I prefer a program from Cakewalk called Plasma. This software is half the price of Soundforge and is very versatile.

Well there you have it. Some good tips to get you started on building your audio empire.

Happy Recording,

John Kiel

Background:

As the HDTV market continues to heat up, consumers are in need of being educated on the latest technology. One of the terms that you, the consumer, will surely run into while selecting a HDTV set is: HDMI. For most this is an unfamiliar term and we will explain the details of HDMI in this article so you, the consumer, is armed with the proper knowledge to make intelligent purchasing decisions.

What is HDMI: HDMI is an acronym for High Definition Multi-Media Interface. The HDMI specification (now at 1.2) was created by some of the largest consumer electronics manufacturers in the world: Hitachi, Matsushita, Philips, Silicon Image, Sony, Thomson, and Toshiba. HDMI is the latest digital HDTV interconnection standard. The notable differences between HDMI and the earlier HDTV interconnects standards (component video, and DVI) are:

-HDMI is all digital unlike analog component video cables

-HDMI supports multi-channel audio in addition to digital video. (DVI only supports digital video)

- HDMI is more compact in size and carries both audio and video signals therefore eliminate cable clutter.

-HDMI incorporates content protection called HDCP ( high definition content protection)

What does a HDMI connector look like: HDMI looks similar to a USB cable. The compact size and high integration (carries both audio and video) makes the HDTV installation experience truly “plug and play.”

Why should I use HDMI:

-HDMI is all digital, so picture quality is “perfect” from source to display

-HDMI is both a digital audio and video connection. This will minimize cabling in your system

-HDMI is rapidly becoming the de facto standard for HDTV connections.

How does HDMI transport the digital video: The video portion of HDMI is carried by 3 separate differential pairs. Each pair transports 1 of 3 uncompressed native digital R,G, B signals from source ( dvd player, set top box) to the sink ( HDTV display). A unique protocol, T.M.D.S.( transmission minimized differential signaling), is used to transport the digital data. Each pixel is represented by 24 bits ( 8 bits each for each of the primary colors). The T.M.D.S. protocol then “calculates” and stuffs 2 extra bits to the video data stream in order to create a digital stream with minimum transitions ( lower EMI, lower interference) and also minimize long strings of ’1′ and ’0′ which can cause detection errors.

A fourth differential pair, called the TMDS clock provides the pixel clock for timing the data stream. The maximum TMDS single link pixel clock rate is 165 MHz.

What is the data rate of a single link HDMI connection: The maximum pixel clock rate is 165MHz and each of the 3 TMDS video streams carries 10 bits. Therefore the aggregate data rate is 3 x 10 x 165MHz = 4.96Gbps.

How many pins are included in the HDMI connector: There are 19 individual pins in the HDMI connector. There are 3 pairs of TMDS signals which carry all the digital audio and video signals.

How is the digital Audio signal transported: The multi-channel audio is time multiplexed into the TMDS data streams. Audio is much lower data rate (192kbps) and the extra time is used to demux the audio signals.

What is HDCP: HDCP is an acronym for High-Bandwidth Digital Content Protection. HDCP is an encryption method developed by Intel in order to control unauthorized copying of digital media. The encryption is carried out in the HDMI transmitter found in the “source” ( dvd player, set top box) and decryption is carried out by the HDMI receiver ( the HDTV display). The secret keys for encryption are exchanged between the source and display over an I2C bus ( pins 15 and 16).

Is HDMI compatible with DVI: DVI is the predecessor to HDMI. HDMI and DVI are identical as far as video is concerned. Therefore, video backward compatibility exists. However, DVI will not support digital audio. For example, if you have an older DVI connection on your source and a HDMI connector on your display, a HDMI to DVI cable is all that is needed in order to view the video. A separate audio cable ( TOSLINK or SPDIF) will be needed to carry the digital audio.

What formats will HDMI support: HDMI is high speed digital connection and will support resolutions of 480i, 480P, 720i, 720 P, 1080i and in the future,1080P.

Conclusion:

HDTV technology is changing rapidly. HD connections such as HDMI will become the de facto standard in HDTV connections. We have outlined the important features of HDMI, so the consumer is well informed and ready to make intelligent purchasing decisions.

In the world of digital audio, there are two types of cable to choose from; optical cables which use light to transmit signal and digital coaxial cable. These audio cables will enable your home theater system to transmit digital data between components. This will provide you with superior sound quality over typical RCA audio cables.

How Digital Coaxial Cable Works

Digital coaxial cables employ the same principles as other coaxial cables. The inner conducting layer is surrounded by an outer conductor as well as the rubbery insulating layer outside the cable. The digital signal is sent through the inner conductor as it travels between components. During the course of its transmission, the signal routinely comes in contact with the outer conductor. The outer conductive layer is created with materials that act as a reflector for the signal, thereby bouncing it back off of its surface. The signal will continue to reflect within the confines of inner conductor until it reaches the receiving component.

Dedicated to Digital Audio

Digital coaxial cable has only one purpose; to deliver digital audio between components. This is in complete contrast to RF coaxial cable which transmits both video and audio along the same path. As you may suspect, dedicating the entire bandwidth of the cable to sending only digital audio has excellent ramifications for your home theater’s sound quality. This practice results in greater signal fidelity between the transmitting device and the receiving component. Greater signal fidelity means that the sound you hear from your home theater speakers will be truer to the way the sound was originally recorded.

Benefits of Digital Coaxial Cables

Digital coaxial cable also has another benefit related to its dedication to digital audio. In the manner that signal transmission usually takes place, the digital signal from the source, a DVD for example, is sent to a digital-to-analog converter (DAC). The signal is converted to analog and sent through the given cable where it reaches the receiving component on the other side. This component uses an analog-to-digital converter (ADC) to reconstruct the digital signal as closely as possible. During this process, errors and variations can be introduced to the signal resulting in audible artifacts and distortions that diminish your home theater’s sound quality.

Unlike with other audio cables, digital coaxial cable can transmit digital signals along its length without the need to convert to analog. Digital coaxial cable is capable of by-passing this process and delivers a cleaner signal to your home theater receiver.

Applications of Digital Coaxial Cables

Connections for digital coaxial cables can be found on everything from DVD players to home theater receivers. If it uses digital audio, then chances are there is a manufacturer who has made that component with digital coaxial cables in mind.
