Spectre 1.5 Takes Audio Analysis to Brilliant New Heights

Latest Version of Real-Time Multi-Analyzer for Mac OS X Includes New Meters, Inspector Window and Specially Priced Starter License

MINNEAPOLIS, Minn. – First-time users and existing fans alike have plenty to discover in the newest version of Spectre, the real-time multi-analyzer from Audio�le Engineering. Developed exclusively for Mac OS X, Spectre 1.5 not only offers versatile and precise tools for examining live audio, but also makes those tools simpler and more approachable than ever before. New features include an Inspector window that reduces desktop clutter, additional metering and �ltering options, and a specially priced Spectre Starter licensing option designed for beginners and students.

“Whether you’re working in a world-class concert hall, a home studio or anywhere in-between, Spectre delivers professional-grade audio analysis at an accessible price point,â€? said Matthew Foust, co-founder and Managing Partner of Audioï¬?le Engineering.

“The new features in version 1.5 include several that were speci�cally requested by users, which makes us even more con�dent in our commitment to providing the best customer support in the industry.�

One of the signiï¬?cant user-suggested features in Spectre 1.5 is the new Leq Meter, which measures the energy of a given audio passage (often referred to as “loudnessâ€?). Unlike typical level meters that measure volume moment by moment, the Leq Meter takes an average over time to provide a useful indicator of how much “energyâ€? is implied in a speciï¬?c passage. The fulï¬?llment of this user-generated feature request led to the creation of a public Roadmap feature for all Audioï¬?le Engineering software. Registered users can visit product pages on the company’s ofï¬?cial website to weigh in on the features and improvements that are most important to them.

Other new features now available in Spectre include A/B/C-weighted �lters, calibration for VU and BBC meters, and a convenient Inspector window that lets users manage the Trace and Settings properties for all active meters in one window.

Students and less experienced engineers can now take advantage of a new license option called Spectre Starter. Priced at just US$49, this feature-limited version of Spectre includes access to the Level, VU, Oscilloscope, Spectrograph, Spectrogram, Waveform, Lissajous and Numerical meters. Users who wish to upgrade from Spectre Starter to the full version need only pay the difference.

To provide consumers with an up-close look at Spectre in action, Audio�le Engineering recently posted a video recap of a Spectre installation at the historic State Theater in downtown Minneapolis. The wide array of musical and theatrical events produced at this grand venue make it a prime location for analyzing and calibrating live audio.
