From ‘Slumdog Millionaire’ to Big Budget ‘Blue’
By Diane Gershuny
Up until about a dozen years ago, the idea and implementation of production sound recording was virtually non-existent in India. As a film school graduate from India’s Film School Institute in 1985—and with inspiration from Spielberg to Lucas—Resul Pookutty aspired to change all that. Riding the wave of the massive success from his work on 2008’s international indie blockbuster, ‘Slumdog Millionaire’ (and subsequent sound design awards including an Oscar, BAFTA, MPSE, CAS, and others), the mixer/sound designer and colleague Akhilesh Acharya launched Canaries Post Sound outside of Mumbai in late ’08. The studio’s main sound design room is built around a Blue Sky 5.1 Sky System One.
Blue Sky Introduces SAT 8 and SUB 212 | abluesky.com
March 12, 2009
The SAT 8 and SUB 212’s Sealed-Box Design, Combined With Sophisticated Bass Management Electronics, Provides A Seamless Transition Between SAT & SUB. The End Result Is A Stunningly Accurate Full-Range Monitoring System.
By Diane Gershuny:
World-renowned for their accurate, full-range sound, Blue Sky is pleased to introduce two new critical listening components to its full line of monitoring solutions: SUB 212 400-Watt Push-Pull Active Subwoofer and the SAT 8 300-Watt, Compact Mid-Field Monitor. The SUB 212 is designed to be an integral part of the monitoring system, enabling a studio monitor, such as the SAT 8, to be positioned for the best imaging, and the SUB to be positioned for the best bass response. Relieving the studio monitor of the requirement to reproduce the low frequencies means that the uncompromising sealed-box design can combine with sophisticated bass management electronics to provide a seamless transition between the SAT and SUB. When combined, the SAT 8 and SUB 212 provide a stunningly accurate and engaging, full-range monitoring system.
“Our customers were asking for a powerful system that was similar to the Sat 12 and Sub 15, but in a smaller package,†said Blue Sky Vice President Chris Fichera. “The Sat 8 and Sub 212 will address those applications.â€

Confusion: LFE, Subwoofer & Bass-Management?
July 4, 2008
When talking to people about 5.1 audio, one of the more common problems in helping people understand certain concepts, is the confusion involving some of the basic terminology.
What is the .1 / LFE Channel and why does it exist?
The .1 or LFE is a channel which is exclusively used for frequencies below 120Hz (below 80Hz for DTS). It is therefore a bandwidth limited channel, but it is not the same as the subwoofer, which is the speaker that typically reproduces the LFE channel in a home audio or studio monitoring system (more information is provided below). The purpose of this channel is to provide an additional 10dB of electrical headroom, for low frequencies, above the main channels. This is done by calibrating the acoustic playback level, so that it has 10dB of in-band gain above the other channels (fronts and surrounds).
Why are TV commercials so loud?
June 5, 2008
As an avid audio / video enthusiast, my friends and family will often contact me when they have a question about their home AV system. One of the most common questions I get, is regarding the relative inconsistency in audio level between different TV programs, channels and in particular commercials. The complaint about TV commercials has been around for a long time, but with the advent of HDTV and digital broadcast television, new technologies are available to the content creators and broadcasters which are designed to mitigate the severity of these differences in level. Unfortunately, even with HDTV and digital broadcast television, the problem hasn’t improved much and in some cases it seems to have gotten worse.
The reasons for the lack of improvement are complex and often vary depending on the content creator, broadcast network and even differences between national and local broadcast networks. To help understand what is causing these ‘issues’, it is probably best to first review one of the key technologies that is available today, to help mitigate this problem. Dolby Digital, which is currently used as the preferred audio delivery format for many HDTV broadcasts, includes several unique features which are designed to help improve consistency between various broadcasts and other audio sources.
Design Philosophy: Blue Sky Studio Monitors

Intro
About 8 years ago, my business partners at Blue Sky and I had a number of meetings to discuss designing a new series of studio monitors. After much debate, we decided there was little point in building another set of “me too†monitors, in the typical 5â€, 6†and 8†2-way configurations. What we felt was needed was a different approach that overcame some of the limitations of current monitors and provided tangible real world benefits to the recording engineer.
So where did we begin?
When creating the requirements for Blue Sky’s nearfield and mid-field studio monitors, we decided to start at the end of the chain and work backwards to the beginning.
