Gear Media Tech Conference …

Pixel Corps has announced open registration for the Gear Media Tech Conference. This will take place at the Zeum Theater (Moscone Center, San Francisco) March 28-30, 2007.

The GMT Conference is dedicated to the skills (technical and artistic) required to produce compelling online content. Whether you are producing audio or video, for phone, web, or mobile device…GMT is a guide to doing this effectively. Lead by some of the industry leaders: Leo Laporte, Scott Bourne, and Alex Lindsay – GMT covers both production techniques and show designs that are key to navigating the next revolution in media.

Scott Bourne suggests … “Due to the extremely limited space, it is doubtful that seats will be available for more than a few weeks. So act fast.”

Doug Kaye on The Scoble Show …

GigaVox CTO Doug Kaye is featured on the latest edition of “The Scoble Show.” This program was recorded in Doug’s home studio. Robert and Doug discuss the history of IT Conversations, and the internal content management system that has evolved into GigaVox Audio Lite. The second part of this program features a live software demo.


Audio for Enhanced Podcasts …

Back in the early days of producing/engineering audio programs for IT Conversations, things were very different in terms of the specific work-flow. For example, audio production engineers manually assembled content and segments using their favorite multi-track editor, mixed down the project, and subsequently preformed additional processing stages prior to uploading the finished program to our server.

We were required to upload two variations, or file formats: AAC [m4a] and MP3. Eventually we phased out AAC distribution. These days, thanks to our internal component show assembly system, all manual aspects of show assembly and MP3 encoding are no longer necessary. [read about GigaVox Audio Lite, our component assembly system … soon to be available to the public].

Prior to the discontinuation of AAC distribution, I set out to find an alternative method or application that would do one thing and do it well: focus on AAC audio encoding for assignments. Why not use iTunes? I support iTunes whole heartedly. However to me, this is a media player and niche` content management system. I never use iTunes for file conversions or encoding.

The purpose of this post in to reintroduce AAChoo, my favorite AAC encoder, and how this encoder may come in handy for you if you produce Enhanced Podcasts using Podcast Maker or something similar.

Aac O-1

AAChoo is a simple drag and drop encoder that offers full customization options to suit your needs. This tool also retains the last group of settings and does not require repetitive calibration. It’s fast, easy to use, and the results are excellent.

In my opinion, Podcast Maker is one of the most well designed and useful applications for podcasters. This application will accept: mp3, m4a, mov, mp4, and m4v media files for possible enhanced podcast management. In most cases the production source file that is saved out by the producer is in the WAV or AIFF file format. This needs to be converted to .m4a in order to prepare it for Podcast Maker. A quick drag and drop on to AAChoo and your new source file is ready to be incorporated into the enhanced podcast work-flow. Chapters and art work can be added, and so on …

The underlying concept is as follows: uncompressed source file to m4a –> done. Using AAChoo for the primary conversion, you can take advantage of the wonderful features that are available in Podcast Maker, and at the same time maintain a high level of audio quality.

I’m aware that Quicktime is an option for the encoding stage. However integration is tedious compared to the drag – drop and encode efficiency offered by AAChoo.

Audio-Technica ATH-M50 Pro Headphones …

Audio-Technica has announced the soon to be available extended range ATH-M50 professional studio monitor headphones. They are specifically designed for professional recording, monitoring, and mixing, providing maximum comfort during extended wear sessions that are common in a studio environment.

At Hp-1

The closed back design of these headphones feature maximum isolation due to their integrated complex driver technology. They support high power/high SPL capabilities, and manage to maintain “clarity, tight bass, and extended high frequency response,” according to Audio-Technica. The integrated single sided coiled cable terminates to an 1/8″ plug, and a 1/4″ adapter is included for maximum compatibility.

  • Frequency Response: 15 – 28,000 Hz
  • Impedance: 38 ohms

The ATM-50’s will be available sometime this month. My guess is that they will perform well for podcast recording and post production. MSRP $199 US.

Mastering Audio: The Art and the Science …

In my opinion a solid understanding of analog and digital audio, recording, production, mixing and mastering is a necessity in order to optimize the quality of your podcast production work-flow. I’d like to recommend a fantastic resource to those of you who are interested in striving for and maintaining high quality results.

Mastering Audio: The Art and the Science‘ by Bob Katz is considered by many to be the bible of audio mastering. Bob himself is an established Grammy Award winning mastering engineer who is responsible for countless hit records. Katz also created the K-Sytem monitor calibration and metering specification. The underlying concept of the K-System is intended to suggest and maintain consistent level and monitoring management for music production, film sound production, and broadcasting.


The first thing that struck me about this book was how easy it was to read considering the complexity of the subject matter. It is for this reason that I find it suitable for all levels of media producers. Are you curious about the technical aspects of dynamic range management, compression, equalization, monitoring, or level management? If so this book is for you. ‘Mastering Audio: The Art and the Science’ will assist you in building a foundation that in the end will help you to achieve optimum results. [$39.99 US]
