New Genelec GLM 4.1 celebrates 15 years of truthful reference monitoring
Genelec – the global leader in professional loudspeakers – is marking the 15th anniversary of its much-loved GLM loudspeaker manager software with the introduction of GLM 4.1 , which is compatible with all Genelec Smart Active Monitors and Subwoofers . This update offers significant new features and improvements , thanks to the debut of the next generation AutoCal 2 automatic room calibration algorithm – which delivers a more precise frequency response in a fraction of the time than was previously possible .
Drawing on the data from thousands of real world room calibrations , GLM 4.1 gives the user supreme control over a room ’ s detrimental acoustic influences , producing mixes that translate even more consistently to other rooms and playback systems . Originally introduced in 2006 and based on decades of research , GLM integrates seamlessly with the intelligent DSP hardware within each Genelec Smart Active Monitor , allowing each monitor and subwoofer to be networked , configured and individually calibrated for the user ’ s specific acoustic environment .
GLM ’ s reference microphone kit allows the user ’ s room acoustics to be accurately analysed , after which each monitor and subwoofer can be automatically calibrated for relative level and relative distance delay , plus subwoofer crossover phase and frequency response . At that point the user has many options for personalisation if required - including the calibration of absolute listening level in dB SPL , according to global broadcast , OTT , gaming and film standards . This level of flexibility makes GLM the perfect tool both for users looking to fine tune an already excellent room , and those working in more challenging spaces not originally designed for creative use .
With the wide range of listening rooms being used for production today , GLM 4.1 specifically improves the calibration of spaces that are more acoustically ‘ lively ’ than was once the norm , and assists those choosing to monitor at ultra nearfield ( UNF ) distances right down to 50 cms – which is now growing in popularity as a bridge between in-room and headphone monitoring .
GLM 4.1 ’ s new AutoCal 2 feature takes advantage of detailed background information of each monitor in a system , producing a quicker and more accurate discrimination between direct and reflected sound . The fast calibration speed is further enhanced by a completely new 64 bit architecture and fresh , lean code . GLM 4.1 is therefore a powerful tool for mobile audio engineers and creatives who are regularly working in different locations . That mobility is also supported by GLM 4 ’ s choice of Cloud-based and local storage of settings .
Users of the 8331A , 8341A , 8351B and 8361A models from ‘ The Ones ’ series of coaxial three-way point source monitors will welcome the new ability of GLM 4.1 to extend phase linearity right down to 100 Hz . With coaxial monitors , phase linearity is a valuable feature because it improves off-axis performance and stabilises UNF imaging too . GLM 4.1 accurately time aligns all the monitors in a room , across types , taking The Ones ’ wide phase linearity setting into account .
Other new features in GLM 4.1 include an increased number of EQ filters offering more flexibility , weighting refinements when taking advantage of GLM ’ s unlimited number of microphone measurement points , and a Solo-X mode for faster soloing of monitors when working with immersive content . Finally , through the addition of French , Italian and Portuguese language options , international users of GLM 4.1 are now able to choose from 10 user languages .
“ The AutoCal calibration algorithm has always been the backbone of GLM ,” comments Genelec Managing Director Siamäk Naghian . “ So I can think of no better way of celebrating GLM ’ s 15th anniversary than with the launch of AutoCal 2 as part of the new GLM 4.1 release . In those 15 years we have gradually seen intelligent loudspeaker calibration become universally recognised as the most reliable path to creating a true sonic reference – and we are proud to keep leading the way .”
