MINNETONKA, Minn. — Minnetonka Audio Software Inc. (MASI), a leader in production software for motion picture, broadcast surround sound, and consumer electronics applications, recently announced that it is now providing worldwide distribution and resales of the Dolby(R) Media Emulator toolkit from California-based Dolby Laboratories Incorporated. This fortifies Minnetonka Audio’s already comprehensive offering of production problem solvers. Minnetonka Audio has added Dolby Media Emulator to its SurCode for Dolby E Master Suite 3 product bundle without raising the bundle price.

 “Our strategic decision to distribute Dolby Media Emulator strengthens our current product mix and expands our reach into more post suites,” said Jayson Tomlin, vice president of business operations at Minnetonka Audio. “For our customers, Dolby Media Emulator is a bargain in itself. By bundling it with the SurCode suite without raising the price, we’ve created a one-stop shop for media producers that is truly an outstanding value.”

Dolby Media Emulator is a software tool for authoring and post that provides real-time emulation for Dolby broadcast formats. Acting as a plug-in for popular digital audio workstations, Dolby Media Emulator enables an audio engineer to simulate accurately how content will sound when played back through licensed consumer electronics.

Dolby Media Emulator lets an operator preview the results of differing metadata values when decoding Dolby Digital, Dolby Digital Plus, and HE-AAC audio formats.

One application worth highlighting: Take a look at this diagram. See all of those speakers? Consider that Dolby Surround formats are varied but most include multiple speakers and therefore multiple positions of "sound". The vast majority of consumers are listening to complex surround signals through only one or two speakers. That means, a proper mix MUST take this into account. Minnetonka's Dolby Media Emulator makes sure you get this right. CP

“With the majority of surround programs being played back in stereo and mono environments, correct metadata and downmix settings are a critical requirement for deliverables,” said Markus Hintz, director of global sales and business development at Minnetonka Audio. “In addition to previewing their metadata settings, audio engineers can use Dolby Media Emulator for standardized loudness measurement, proper  monitoring of LtRt sources, and downmixes from all other sources.”

Rather than resort to using home audio gear in a professional workflow, engineers can use Dolby Media Emulator to validate mix and metadata decisions against a certified standard in their familiar monitoring environment.

To aid in specifying proper metadata values, Dolby Media Emulator can measure and properly determine the dialogue normalization (dialnorm) value with a standardized loudness meter. The included loudness meter supports international ITU-R BS.1770, ITU-R BS.1770-2, and EBU R-128 loudness standards and incorporates the optional Dolby Dialogue Intelligence(TM) algorithm. Its ability to configure and control the monitoring environment and evaluate metadata parameters makes Dolby Media Emulator an essential product for postproduction, DVD, and DTV facilities that master, author, or broadcast program material with Dolby surround sound formats. Dolby Media Emulator runs as an Avid(R) Pro Tools(R) RTAS(R) plug-in, and as a VST(R) plug-in for popular programs such as Nuendo(R).

Dolby Media Emulator is available for immediate delivery from Minnetonka Audio resellers and distributors, and also directly from Minnetonka Audio’s eShop. In-depth information on Dolby Media Emulator and how it enriches existing tools and workflows is available at www.minnetonkaaudio.com.

Watch LIVE and archived streams of Mars Rover Curiosity

Leave a comment
We’re back on Mars!

If you’re a space geek, science fan or techno nerd then you may already know a bit about the latest planetary lander called Curiosity. Today (August 6th, 2012) this engineering marvel (not to mention the challenge of sending and landing) sits near Gale Crater (this crater is so big there’s a mountain called Mount Sharp inside it CP) and prepares to investigate some of the most geologically interesting areas on the Red Planet.

What’s the big deal? This is an investigation that could unravel the greatest mystery of all…..”is/was there life out there?” So without further ado, here is the LIVE stream with real time chat. Update Aug6 10:03PM EDT the first LIVE stream has ended but has been archived and will play in the window below. Other LIVE streams will play in real-time as the mission developments continue. CP Update Aug22  1:03PM EDT we will be streaming the LIVE NASA press conference with updates on the mission and rover status. Video feed begins at 2:30 PM EDT CP

The MARS/NASA/JPL team showed media the first scientifically laser-beamed and analyzed Mars rock during today’s press conference. This Basaltic rock (called Coronation by the team) displayed interesting hydrogen variations and preliminary results showed more hydrogen measured on its surface with exponentially decreasing amounts as the laser probed deeper.

The plan now before searching for water, is a ramping up of technical and rover checkouts, a more thorough planning order of activities and lengths, driving the rover to new sites for rock drilling and investigating what scientists are calling ‘scours’- ground indentations made by the Sky Crane thrusters during the descent of the Mars rover.
Scientists caution the fact that there are no definitive time tables for upcoming tests. This is due to such unpredictable conditions as weather forecasting and rover checkouts and performance. As these tests are conducted and checkouts are completed, the Mars team hope to learn how to ‘fine tune’ future tests after properly calibrating the rovers testing instruments. For example, the wavelength instrument is affected by the slight temperature shifts from the time of the Mars day and from the rover’s movements.

Reporter questions focused on the geological aspects of today’s conference and the team responded enthusiastically about plans to drive the rover to areas that have bedrock and opportunities for testing varied rock types. A short video in honor of deceased science fiction author and Mars fan Ray Bradbury rounded things out. As one scientist put it “ We are only 16 days into a two year mission.” Stay tuned. CP
