DVD Audio: An Introduction

DVD Audio is a music format that is designed to offer improved audio performance over CD. The new audio format can be used to provide listeners with Advanced Resolution stereo and/or multi-channel (up to a maximum of six channels) music. In order to play back DVD Audio discs, players have to be specially designed to support the format. So far, consumer electronics manufacturers have announced a range of DVD Audio players, including home decks, portable players and devices for cars.

DVD Audio has a sampling rate of up to 192kHz compared to a maximum of 44.1kHz for CD. It also supports resolutions of up to 24 bits, compared to 16bits on CD.

The idea behind DVD Audio is that it allows producers to give listeners a playback experience that is much more faithful to the original master recording that has been possible previously.

DVD Audio discs have a much higher capacity than CDs. This extra space can be used to provide audio at the highest possible quality or for longer recordings, or to provide additional material, such as information on the artist, photos and even video, all of which can be displayed on a television screen. Alternatively, DVD Audio discs currently on the market from the likes of the Warner group of labels have the audio content in both DVD Audio format and as Dolby Digital surround so that they can be played back on regular DVD players.

DVD Audio discs are navigable in the same way as DVD Video when played back on a player connected to a TV set. Users can select the required track from an on- screen menu and with an internet connection, can click on links to go to websites.

These dual format discs are a good way to kick-start the market while DVD Audio players are still relatively rare. The market will also be helped by combined DVD Video and Audio players.

Alternatives to MP3

Although MP3 is the most popular format for encoding music, it is by no means the only one. There are two basic methods for compressing audio ? lossless and lossy, and for each of these methods there are many formats.

Lossless compression means that none of the audio data is removed during compression. Lossy compression means that audio data is permanently removed from the audio file. Lossy compression results in smaller files, but there is no way to rebuild the audio data to its original format. MP3 is an example of lossy compression.

Lossy Compression Formats

There are many alternatives to MP3 when it comes to encoding audio files. Microsoft reportedly developed the WMA format to avoid the licensing costs associated with MP3. WMA files can be played with the Windows Media Player that is included with the Windows operating system as well as many other audio players. It features similar encoding rates to MP3 and similar file sizes.

AAC (Advanced Audio Coding) is the format preferred by Apple and is used for its popular iTunes and iPod products. AAC files can be smaller than MP3 files because it uses more efficient encoding technology. A 96 kpbs AAC file is similar in sound quality to a 128 kbps MP3 file.

Ogg Vorbis is another type of lossy compression and uses .OGG as the file extension. It is an open-source product and unlike MP3, there are no patent restrictions on its use.

Lossless Compression

For the audio purist who insists on the best quality sound possible, lossless compression offers CD quality sound. The tradeoff is larger files sizes ? while MP3 can compress audio in the range of 80% - 90%, lossless compression typically compresses the file by half.

Popular lossless formats include FLAC, Monkey's Audio, and SHN (Shorten). These formats are supported by many audio players and are popular for archiving CD collections as well as for trading music.

Heres Exactly What Makes Web Audio So Powerful

Have you ever tried to communicate with another person using just actions and sign language? It gets pretty frustrating, doesn't it? Especially when you know that if you could just SAY a few words, they'd get the picture, almost instantly.

Well, imagine if the website you've put up on show... could "speak". If it could sparkle with the spoken word. What do you think the effect could be?

You see, what the smart website marketers have realised, is that they need to move beyond just written words and striking graphics. They're looking to giving their website? a 'personality'.

BUT? in the cold hearted, faceless world of the internet, being able to reach the audience you want, with sincerity, warmth and with a 'face', doesn't come easily to most.

That is unless you happen to have the skilful knack of knowing what to write, when to write it and are able to string words together to help paint a strong emotional picture in readers minds for your product, service or idea.

Getting all the help we can via other means is crucial in giving us that slight edge.

There's possibly nothing more intimate, more convincing, more realistic for the reader, than to hear a 'voice' behind the website. What it adds, is satisfying helpings of?

LIFE and? CREDIBILITY!

Imagine being able to connect at regular intervals with your customers and clients! How do you think they'll feel when you're able to inform them that there's an exciting offer about to happen and you make sure the message reaches both their eyes, and their ears!

What about using this simple technology to help create a stampede of sales, an abundance of new subscribers, a fleet of qualified prospects, a herd of new referrals!

What about being able to tell your customers that you messed up on the last bit of information you gave them and that you're really sorry. Won't you be able to convey this message better using real live words, than by using written text?

Won't your sincerity, conviction and heartfelt emotion, reach them INSTANTLY, where it matters most? THEIR HEARTS!

Dont Use Web Audio The Wrong Way

Have you ever wrestled with a set of instructions, but then got so frustrated with it all that you threw them aside in a fluster and tried to figure out how to do it? yourself?

Resulting in?Making a great big mess of it all?

Similarly, if you really want to use Web Audio the right way, the way that WORKS, then you need to know what DOESN'T work.

Here's what many people do, pretty systematically? to hinder their marketing and audio responses:

1. Speaking into the microphone without a care for what they're saying, how they're saying it and, without any regard to who's listening! That's pretty scary. Mumbling along without paying any attention to the small details. It's what could sink the hopes of many? FAST!

SIMPLE SOLUTION - Write out a little script. Then, rehearse it. After that, record it several times. Finally, choose the best of the lot and use it. See, I told you it was pretty simple.

2. Some feel that hiring a 'PROFESSIONAL' or 'DJ', to record the voice audio, is the way to go. Now, for some, that may seem a reasonable way out, but what's likely to happen is that the websites' PERSONALITY loses its authenticity. Somehow, most of us can detect when things seem out of sync. When things seem a little too? SLICK!

SIMPLE SOLUTION - If you really want to get someone else to do the voice audio for you, then make sure they've got a warm, natural personality that shines through in their voice. It'll win people over.

3. Sending the recorded audio message to your website, and then? FORGETTING ABOUT IT! Have you ever dialled a phone number, got an answer machine message that was either way out of date or just plain irrelevant? What an unprofessional image to portray. Well, that's why NOT attending to what's on your messages, could cripple you more than you'd know!

SIMPLE SOLUTION - Keep your audio updated! I'm not saying that you have to micro-manage it and change it every other day. But, keeping your messages fresh, alive and full of valuable, useful and usable information that addresses the needs of your audience? is what'll keep them loyal, attentive and eager to receive your future messages!

4. Leaving your audience mentally floating, not knowing what to do next. Have you ever experienced a scenario similar to this one: Whilst waiting on a train platform, an announcement is made to the waiting passengers as follows,

"due to a fault on the line, please expect further delays".

I'm in no doubt at all that this announcement would have left the passengers feeling concerned, confused and wondering what to do next. What the announcer should have taken the time to add is as follows,

"as we have not received any information from our control centre indicating the expected length of delay, you may like to consider hopping on bus number 19, leaving the bus stop adjacent to the station entrance in 7 minutes time. Otherwise, please continue to listen for further announcements, which we will endeavour to make every five minutes. Please also accept our sincere apologies for the delay and any inconvenience this may have caused you".

SIMPLE SOLUTION: People are silently begging to be told what to do next. If you can lead them to a specific outcome, they'll be putty in your hands! Whether it's instructions to go to a specific toll free number to get more information, or something they have to activate, like a membership number, whatever it is? tell them PRECISELY how to do it.

Web Audio, used correctly, will have a dramatic impact on the way in which your customers respond to you. They'll be so 'stuck' on your website and addicted to your audio messages, that you'll soon be sending out birthday cards to them!

FLASH AUDIO WIZARD has a simple in-built technology that'll give you the website personality you've always dreamed of. It's simple to use. It's easy to get started.

wav; Recording Voice or Instruments

A graduate student in Belfast wrote to me about a project he was doing. It is an inter-active instructional CD on the Tin Whistle.

Obviously here is another application where you would record direct to wav. and forget about the midi. format.

He wanted an authentic sound and midi. would never provide this. You might get close, if you used the right sound card or plug-ins and I will go into this in more detail in later writings about midi.

If you can play an instrument or sing, you will want to record directly to wav.

The procedure is much the same as when you record a tape or L.P. The key element here is to use a very high quality microphone.

Plug the microphone into the microphone input of your sound card which will be the one with the picture of a microphone on it.

Find the software for your sound card, (try accessories, if your computer came with a sound card,) and select the microphone input from your options or file menu. You are all set.

If you have a good sound card, it may have come with a few other features that are useful; If it has a mixer, set the level of your input so it doesn't go into the red. This is important to eliminate 'clipping,' when you record.

'Clipping' is an unpleasant sounding distortion from having the levels too high.

Also, your sound card may have come with some effects processing. These effects must be used 'on the fly.' That means they are utilized while you record rather than applied to the recording later.

Don't be intimidated by this. They are easy to use and a lot of fun. Most likely you should use some of these effects, if you want a more professional sounding recording.

Find the effects in the software for your sound card. These are usually available in what are called 'presets.' This means they are already created for you and given a name, such as 'vocal chorus.' 'Chorus' is an often used effect for vocals. It gives vocals that rich 'singing in the shower' sound.

Reverb and delay are also used to enhance the richness of the tone.

Try some different effects out and select the one that you think sounds best and record with it.

The sound card may even give you the option of mixing your own effects. This will simply require a bit more trial and error but can be very fun and worthwhile.

If you want a really authentic sound of a folk instrument, you may not want any effects at all.

Get Personal by Adding Your Voice to Your Site

Many customers in today's online business world are shopping around online for a reason; either they are too lazy to go to stores, do not like the masses of people, or they might just want to shop in the comfort of their home. What ever the reason might be, we can conclude that they are not in a store, but rather they are on your site. Just because your businesses is online doesn't mean that you can't conduct your business like that of a normal store. Compare your site to a clothing store in a mall for example. When the customer comes in, a sales representative normally comes to the door and asks if they need help. A web site doesn't normally do this, but you can if you want to. Record an audio clip that not only includes a sales pitch and introduction but also a site map that includes the important parts of the site. Not only are you getting personal with your customer, you are also pointing them in the direction of your product. Here are a few tips to keep in mind about audio clips:

#1 - Make Sure They can Turn it Off

There is nothing worse than listening to someone drone on on how they made massive amounts of money, and so can you! If you do include audio with your site, make sure you include a stop button. You might think you sales pitch is interesting and informative, but the customer might not. They might also want to play it over again to catch a part they missed, so make sure to include a play button as well.

#2 - Include a Picture

Maybe is just cause we watch TV alot but when we hear audio, we want something to look at. Take a picture of yourself and put it above your new stop and play buttons. It will add to the personal touch and also give the people something to look at while they listen to you.

#3 - Don't Take too Long

People have short attention spans so introduce yourself and your site, make your pitch, point them in the right direction, and then stop. You can always include more audio files with success stories elsewhere on your site.

#4 - Don't be too Loud

It is hard to know how loud to make your clip but it is better to be soft than to be loud. The user can always turn up the volume if they are interested. Adding a volume "slider" next to your play and stop buttons and below your picture will round off the audio clip look.

So there you have it, four great pieces of advice when looking to add an audio file to your site. If you can do it yourself, put one up there, but if you can't, get someone to help you. It is relatively easy and so it should not be too expensive. Good luck and be creative!
