Studio drummer Dylan Wissing — known for his work with Alicia Keys, John Legend, and Drake — demonstrates the real-world impact of adding diffusion and absorption to a drum room. This video walks through the sound of the room untreated, then with Evolution PolyFusors, then with Amplitude™ Acoustic Panels, and finally with a combination of both. A practical, ear-opening listen for anyone treating a recording room.

Acoustics designer James Lindenschmidt joined Gravitas Create for a live Facebook Q&A, fielding questions from the community about studio acoustics setup. Gravitas Create compiled the full session into a report — this article links out to it. A useful resource for anyone with questions about treating a studio or listening room.

Building on Part One, James Lindenschmidt dives into subwoofer placement strategies for flattening bass response — from basic corner placement to ¼ null-point positioning, crossover tweaking, and using two or four subwoofers to cancel out axial modes. An essential read for anyone with a subwoofer/satellite system looking to maximise low-end accuracy.

Getting speaker placement right means balancing two competing problems: stereo imaging and accurate bass response. In this first of a two-part series, James Lindenschmidt explores equilateral triangle setups, dual monitor configurations, room modes, SBIR, and when subwoofers can solve the compromise entirely. Essential reading for anyone setting up a listening room or studio.

Treating a recording room follows the same acoustic principles as a listening room, but the application is different. James Lindenschmidt walks through the key strategies — finding your sweet spot, bass trapping, managing early reflections, and balancing diffusion — to create a versatile, great-sounding space for recording drums, vocals, and full bands.

1D diffusors scatter in one plane, 2D in both — but which is right for your room? This guide breaks down the real differences between one-dimensional and two-dimensional diffusion and explains which works best for listening rooms, live rooms, and everything in between.

Diffusion is the most misunderstood acoustic treatment option. This deep dive breaks down the three main types — Reflection Phase Gratings, Geometric diffusors, and Binary Amplitude panels — explaining how each works and when to use each one.

From mic technique to acoustic treatment, this guide covers every strategy voiceover artists need to produce clear, professional tracks — whether you're working in a dedicated studio, a treated bedroom, or an untreated room with portable panels.
