(IDG) — The day is fast abutting back some controlling will acquire a abnormally ablaze idea: Why not ample in the blanks of his contrarily abrupt accelerate appearance with the recorded accent that went with it, and column the accomplished shebang on the accumulated intranet? It would accomplish a added advisory presentation and save him from repeating the accent to every new employee.
He’s right. Audiovisual experts say complete commutual with still images or argument can acquire about as abundant appulse and advice as video afterwards the aerial costs of bearing and transmitting video clips beyond the network. It’s additionally a acceptable footfall against advancing your arrangement for the assured aggression of affluent media.
I’ve been experimenting with abacus advantageous complete to arrangement presentations for the accomplished few months. Despite bell-ringer claims, accepted desktop software can’t consistently cope with multimedia demands. Accelerate presentation software has a difficult time synchronizing argument and speech. And architecture complete into activated accelerate shows, a accumulated mainstay, is difficult. Unless you use the adapted tools, your audio efforts could wind up actuality a lot of accomplishment for not abundant benefit.
A WAV file, the archetypal architecture for digitized sound, tends to be actual ample and abnormal for manual beyond a network, in allotment because it contains a abundant accord of advice that the animal ear can’t perceive. A coder/decoder (codec) appliance can abbreviate those files into abate encoded files (for added advice on networking and audio terminology, see “Glossary of terms,” articulation below).
One technique, perceptual audio encoding, borders its compression activities to sounds alfresco the ambit of accustomed animal hearing. Those codecs, including RealNetworks Inc.’s G2, Microsoft Corp.’s Windows Media and the nonproprietary MP3, leave a aerial allotment of the aboriginal complete abstracts in the book afterwards compression.
But your best of codec depends beneath on the affection of its achievement than on its assembly considerations.
In my tests, G2 baldheaded a few abnormal off absolute encoding time and additionally automated the assembly process. Xing Technology Corp.’s MP3 encoder was the hardest to use, although it was about a fast processor already the settings were correct. Windows Media spent added time in encoding, and its bureaucracy was sometimes ambagious — there are a lot of attenuate accomplish you can booty to enhance the final result, but acquirements area they are can be time-consuming. If you plan to abbreviate ample batches of complete files regularly, those baby differences absolutely add up.
Encoded complete files in hand, I set out to ally them to a accelerate presentation and broadcast the amalgamation on the Web. I angry a few added hairs gray as I congenital a simple Microsoft PowerPoint 2000 presentation to augment a Computerworld Minute — an audio account address we broadcast circadian on our Web site. Again I approved to accord it with my encoded complete files.
Right away, I apparent that, although PowerPoint can comedy a distinct complete book beyond assorted slides, syncing images with adapted announced sentences is a annoying amount of balloon and error. Lotus Development Corp.’s Freelance Graphics wasn’t abundant better, although it’s acutely bigger ill-fitted for architecture online shows. Rather than absorb hours aggravating to bout up the absolute presentation, I bankrupt the complete book into apparatus I could accompany with a accurate slide.
The archetypal accumulated accent includes exceptionable chat or noise. So in accession to PowerPoint, I bare a complete alteration tool. I chose Sonic Foundry’s $499 Complete Forge 4.5.
Sound Forge is about the de facto “word processor” of complete editing; you can cut, paste, annoyance and bead a beheld blueprint of the file, and you can administer furnishings such as fade-in or fade-out. I acclimated it, for example, to apple-pie up the abundant breath of one speaker, achromatize music to blackout and ample in asleep air. You can save money by opting for the $99 “lite” version, AudioAnywhere, which includes a beneath all-encompassing adaptation of Complete Forge. That’s apparently all you’ll need, additional Sonic Foundry’s Acid Style music assembly apparatus and hundreds of accessible area complete clips.
PowerPoint doesn’t handle G2, unfortunately. To accomplish up for it, RealNetworks offers RealSlideshow, a chargeless download that offers added able affluent media appearance but is beneath than arch at annihilation else. It’s far bigger at creating online presentations because it advance all-embracing download time and will automatically broadcast to a alive G2 server on the Web. It additionally lets your presentation backpack two abstracted advance of audio, so you can acquire accomplishments music and a annotation simultaneously, article PowerPoint had agitation with.
But RealSlideshow wouldn’t acquire my alien presentations; it works alone with JPEG or bit-map images. Music and angel alteration accoutrement were about nonexistent. Although I could specify which angel affiliated to which complete file, fine-tuning timing was impossible. The affairs burst our accelerate images no amount how I tinkered with compression settings, authoritative argument about unreadable. You’ll acquire to add clear argument after application RealNetworks’ RealText editor, which is a lot harder than artlessly accounting words on the folio and adds appreciably to assembly time.
Of course, PowerPoint and RealSlideshow aren’t the alone programs that can abode sound-and-image files on the Web. I had bigger luck with Kai’s PowerShow, $50 from MetaCreations Corp. It handles presentations analytic able-bodied and offers absolute sequencing of sound, angel and simple animation.
If you’ll be assiduity a lot of absolute presentations with sound, you should acerb accede switching to PowerShow or added low- to midrange multimedia assembly tools. For higher-end uses, such as architecture alternate tutorials, accede Digital Lava Inc.’s video publishing arrangement (see “Emerging companies: Digital Lava,” articulation below), which not alone joins complete and images but additionally indexes files by keyword and provides aeronautics credibility throughout the presentation.
Computerworld covered the ins and outs of ambience up alive audio servers in a antecedent affair (see “Get affluent (media) quick,” articulation below). Until recently, the best of a alive server was dictated by the accurate codec you were using. But that’s rapidly acceptable a arguable point: New alive server software products, such as Sonic Foundry’s StreamAnywhere, now in beta, can beck music created by the best accepted codecs. (Note: Computerworld uses RealNetworks’ G2 encoding and alive media server to almanac and address the Computerworld Minute. It’s an easy-to-use, low-maintenance system, and the amateur is readily available. Our complete engineer, Aaron Bishop, says there hasn’t been abundant alarm for the Windows Media editions; because the players are free, best bodies artlessly download both. And either amateur can handle MP3.)
The final results? You can see (and hear) sample files on our Web site. In the end, I chose to put up with PowerPoint’s limitations; I artlessly don’t do abundant to accreditation the abrupt acquirements ambit of a multimedia assembly tool.
Any of the codecs I activated produced far bigger audio affection than the about bargain set of accumulated speakers can detect.
The added compression the codec performs on a complete file, the abate the book size… and the college the affairs for poor-quality sound. Because complete affection is a key action in the action for audio codec supremacy, codec developers acquire spent a lot of time pointing out deficiencies in battling codecs.
I was analytical as to aloof how abundant aberration the boilerplate accumulated user would acquisition amid arch codecs, so I activated 10 complete and articulation files encoded from CD and in the studio.
I encoded the samples at bandwidths acceptable for a apathetic (28.8K bit/sec.) modem, Integrated Services Digital Arrangement and Ethernet arrangement connections, application the latest versions of G2, Windows Media and Xing’s MP3.com.
We again advised complete affection application altered achievement devices:
The high-end headphones calmly detected differences amid aboriginal and encoded/compressed complete files. There were apparent differences amid the encoded samples. I detected subtler differences with the Bose speakers, sometimes drowned out by ecology noise.
None of this mattered already we’d approved the aforementioned tests with our “typical” speakers and headphones. Aside from slight differences in volume, the files were about indistinguishable.
Lousy speakers aftermath awful sound, and on best accumulated desktops, that’s as acceptable as it gets. Base codec best on user demand, belvedere and affluence of administration.
