Genelec GLM 4 Smart Active Monitor Control Software Released

Genelec has announced a major free upgrade to their GLM software for audio monitor system setup, calibration and control. The next-generation GLM 4 now gives users a new user interface and a host of valuable new features including macOS Catalina support. We have all the details.

Minimise The Room’s Influence

Designed to minimise the room’s influence on the sound quality, Genelec GLM 4 is designed to provide a reliable sonic reference - wherever the user chooses to work. GLM 4 integrates with the intelligent DSP hardware within each Smart Active Monitor, allowing each monitor and subwoofer to be networked, configured and individually calibrated for the user’s specific acoustic environment.

Automatic Calibration

GLM’s reference microphone kit allows the user’s room acoustics to be accurately analysed, after which GLM’s AutoCal feature automatically optimises each monitor and subwoofer for level, distance delay, subwoofer crossover phase and room response equalisation.

Manual Personalisation Available Too

At that point the user has many options for further manual adjustment, thereby achieving complete personalisation if required. This level of flexibility makes GLM 4 the perfect tool, in conjunction with Genelec Smart Active Monitors, both for users looking to fine-tune an already excellent room, and those working in more challenging spaces not originally designed for creative use, which is especially useful for users working from home in less than ideal rooms.

New User Interface

Compatible with Windows and macOS, including 10.15 Catalina, GLM 4 comes with a brand new user interface designed for faster, more intuitive and easier navigation. Created in conjunction with leading industrial designer Harri Koskinen, the new user interface uses Koskinen’s hexagonal design has been created to support the concept of natural growth, in the sense that GLM aims to help develop the user’s own listening skills and provide a monitoring system that can be expanded from mono to complex immersive as the user’s needs evolve.

What’s New In GLM 4

GLM 4 offers all the functions of its GLM 3 predecessor, with the addition of new features including dedicated setup and control functions for immersive monitoring, and compatibility with the increasing number of audio monitoring standards in international mastering, broadcast, OTT and film. GLM 4 supports Cloud-based and local storage of settings, giving the user options for complete mobility, with the Cloud helpdesk always on hand to provide remote consultancy via a team of Genelec audio experts.

In conjunction with the DSP hardware built into all Genelec Smart Active Monitors, GLM 4 is designed to offer the user unique benefits that Genelec claim no other room calibration system can offer. GLM 4 supports fully scalable systems from mono and stereo to more than 80 channels of immersive reproduction, making it the most advanced, flexible and cost-effective room calibration system on the market. The tight integration of hardware and software is designed to ensure the best possible system performance and dynamic range enabling the user to switch between monitor setups without having to use extra DAW outputs - or invest in costly external hardware.

Want To Know More About GLM 4 From Genelec?

Genelec is hosting a global launch event on December 15th 2020 at 6 p.m. GMT (1 p.m. EST), to present their new GLM 4 software for audio monitor system setup, calibration and control.

Join hosts Darren Rose and Markus Kahelin as they explain GLM 4’s new features, before introducing contributions from GLM users Sylvia Massy (Engineer & producer, Museum Studio), Morten Lindberg (GRAMMY®-winning engineer & producer, 2L Records), Goh Hotoda (GRAMMY-winning engineer and producer, Studio Go) and Nick Mac (Chief engineer, Electric Feel Studios).

Genelec’s support team will be answering any queries via live chat throughout the event, so visitors are invited to get involved and fire questions at the team.


Since the management and optimisation of the system take place at the end of the signal chain - in the monitors and subwoofers themselves - GLM 4 users can benefit from fixed and low latency performance without having to bypass any monitor optimisation software sitting on the user’s DAW master audio buss. This eases the creative process by avoiding the need to switch between ‘record’ and ‘mix’ modes, and once calibrated, GLM 4 settings can also be stored within the monitor or subwoofer itself, avoiding the possibility of accidental changes - making GLM 4 ideal for multi-user rooms and demanding production environments. Genelec Managing Director Siamäk Naghian told us…

“GLM 4 is the distillation of many years of continuous research into the effects of room acoustics on monitoring system performance, and will help to streamline the user’s workflow and elevate the quality of their mixes. In line with our design philosophy on sustainability, GLM 4 is also completely backwards-compatible with all generations of Smart Active Monitors. This means that professional users can not only be confident that GLM 4 is the most advanced, efficient and intuitive room calibration system on the market, but it also guarantees that Genelec Smart Active Monitors are an extremely secure, scalable and future-proof long-term investment.”
