NTi Audio Offers Rapid Frequency Response Measurements with the XL2

Do you want to measure the frequency response of a speaker or audio component, and not have to wait until the lower frequencies stabilize? NTi Audio offers an innovative and practical solution with its Minirator MR-PRO and XL2 range of measurement instruments. The measurement uses two new MR-PRO test signals and a new, matching measurement function in the XL2, in which the signals contain a 1-second and a 4-second cyclic pink noise, from which the XL2 can quickly calculate a stable measurement result in real time.

KRK Systems, (still) part of the Gibson family of brands, introduced its new KRK Audio Tools App for iOS and Android. The free suite of professional studio tools includes five useful and professional analysis-based components that work with any monitor setup, and one powerful tool (EQ Recommendation) that helps acclimate the new KRK ROKIT G4 monitors to their individual acoustic environment.

Usually we think of noise as a signal to be eliminated, or at least reduced, in any audio system. However, noise can be a very useful test signal because it is inherently broadband, which is faster and perhaps more accurate than spot or swept frequency testing.

Hush, successfully funded on Kickstarter, is the world’s first set of connected earplugs that wirelessly connects to a smartphone, to help people live and sleep when it’s noisy. Hush combines noise-masking earplugs with an app to isolate users from distractions that may be keeping them from sleeping, while still letting key notifications in.
