Audio: The Movie was born from our popular DC LIVE/Forensics Audio Training. This 3 day course is designed to help Forensics professionals better learn our tools, methods of evidence gathering and preservation as well as learning about audio in general. The early part of this course is a basic overview of audio and how it works. We were amazed at how many audio veterans approached us after these early sessions and said things like, "I've been using that term for 40 years and never really knew what it meant." Audio is a science that can be pretty complex at times and we felt it might be interesting to explain in simple, easy to understand terms, the science of audio and its special nuances.
If we have one gift at Tracer, it's our ability to take complex things and make them easy. It's why our tech support is the best on the planet and why the manuals we write for products like DC SIX, help take the edge off of sometimes confusing stuff. Audio: The Movie is a wonderful example of how you can take college level material and present in a way that anyone can understand. If you have an interest in audio or just work with audio as a hobby, this DVD will explain the complex world of audio without the math and with easy to understand theories presented in a unique and entertaining form. If you think you already know everything there is to know about audio...you may just be surprised.
"For those who don't know much about audio, the entire video is likely to be helpful. But even audio veterans might learn a thing or two. For example, I never knew why 44.1kHz was chosen as the standard sampling rate for CDs until I watched the video. Another cool part explains why Nyquist's theorem is justified in drawing the conclusion that you can reproduce a 20kHz sine wave at a 44.1kHz sample rate- but then explains some valid reasons why higher sampling rates can indeed produce audio that's perceived as sounding better. Frankly, their explanation rang truer with me than a lot of what audio manufacturers are putting out into the world. And did you ever wonder why an audio CD can store more megabytes of data than a data CD? I didn't, so either I'm dumb, or this video covers some material of interest to more than just beginners." Craig Anderton, Harmony Central
"Among the topics covered over the DVD's eight chapters are sine waves and complex signals, frequencies, understanding loudness and dB measurements, and the world of digital audio—bits, sample rates and sampling, etc. Two hours doesn't sound like much, but an incredible amount of information is imparted in that time. It seems like it would provide a nice overview to students just getting into audio, or it could work as a refresher course for more established pros." Blair Jackson, Mix Magazine
"If you teach Audio Production or a similar course, you might be interested in using Audio: The Movie, produced by Tracer Technologies, as supplementary material. While the packaging states the DVD “… is a college level course that will help you understand the principles of audio but bypasses most of the mathematics usually associated with such studies,” another statement on the DVD suggests it is “a course in audio theory for normal, average, every-day folks.” Finally, their website notes “…this information is provided in easy to understand terms…” and, for the most part, the viewer will find all these statements are fairly accurate.
