Most home or project studios are located in smallish rectangular rooms, creating a real challenge in creating a relatively accurate listening space. Parallel walls reinforce and nullify harmonic frequencies, creating peaks and dips in the frequency response, particularly between 50 and 250Hz. A common mistake is the overuse of thin acoustic panels (50mm and less),…

Lynx Aurora vs Digi 192
There has been plenty of good things written about the Lynx Aurora DA AD converter, and how it beats the pants off the Digidesign 192. After much deliberation, I had to find out myself, particularly as the Aurora 8 is a fair bit cheaper than the 192. I’ve had the Lynx for a week, and…
Acoustic Foam: is it all the same?
Just a quick one. A common criticism of acoustic foam is that it will not absorb low frequencies. This is a very common point of view expressed on forums that is simply not true. At risk of repeating myself, the ability of acoustic foam to absorb low frequencies is related to thickness, structure and density.…
Voiceover booth – acoustic treatment
Recently one of our customers (a radio station in South Australia) installed both the HA600-75 acoustic panel (absorber/diffuser) and the SA600-75 acoustic panel (broadband) in conjunction with some custom made acoustic treatment. The HA600-75 is ideal for this application as it retains a sense of space while absorbing problematic lower frequencies. It also exhibits remarkable…
Bass Traps in the Bedroom
Bass traps are generally the first component of an acoustic treatment for a project studio in the bedroom. A bit of flutter echo will mess far less with your mix or listening, than will uncontrolled low frequencies. High frequencies will smear your imaging a bit, but low frequency dips and peaks will do your head…
Heil PR40 Microphone – a quick review
I recently became curious about the Heil PR40, having read a number of good reviews on the web. It is a dynamic end address mic with a very wide flat frequency response from 28Hz to 18kHz. It is capable of handling very high SPL’s, which makes it a very versatile mic. At around $300 US,…
Acoustic Foam vs Semi rigid fibreglass
I often read in forums (Gearslutz etc) ongoing arguments about polyurethane bass traps (such as ours) versus semi rigid fibreglass. It is often stated that polyurethane will not absorb low frequencies, which is absolutely false. Thin wall panels won’t absorb low frequencies but a large volume corner trap is very effective in absorbing low frequencies.…
