Think Beyond the Usual

Smart Filtering | Acoustic Zoom | Transient Shaping

This EQ plug-in for audio editing balances spaciousness and makes the postproduction of music and speech creative again.

As technicians and acousticians with an affinity for sound, we’ve long dreamed of entering a new dimension of EQing - a dimension that goes beyond today’s equalizing, one that leads to fun sessions in postproduction. With our totally innovative plug-in, that dimension is finally here. Producers can look forward to the company of a new muse: the 3in1 audio plug-in called frei:raum.

When you open the user interface of the 7-band and linear-phase EQ, familiar arrangements guide you into an intuitive working mode. Behind the user-friendly interface, there’s a cleverly devised algorithm that works on three levels each focusing on a different segment of editing. On these levels, new doors open to a space that provides you with completely new possibilities in terms of spectral balance, sound depth, and tonality.

Entropy Layer

Who hasn’t experienced the most common issue with original sound? Sometimes it’s too slurred, sometimes too harsh. We used to struggle to adapt the harmonic to the noisy sound portions, trying in vain to create the perfect sound character. The entropy:EQ simplifies the postproduction of impact noise as you know it, whether from drum beats, guitars, or other plucked instruments. Even the intelligibility of voice can be effortlessly improved, by enhancing not the harmonic, but the noisy components of the sound. This reminds listeners of a zoom-effect by which the speaker gets acoustically ‘closer’.

Proximity Layer

On the second level, you’ll find a tool that solves problems caused during recording, like, for example, microphone settings. We all know that panicky feeling – at the end of postproduction – when the sound still reminds us of a warehouse or a basement rehearsal room. This usually happens when the interviewer doesn’t get the mic close enough to their conversational partner’s mouth, resulting in that slurred sound on the tape. Maybe you recorded the tracks in an acoustically imperfect room, or the distance from the choir or instrument to the recording mic was less than ideal. In exactly these situations, the proximity:EQ lets you get back the sound you wished for. Thanks to the separation of direct reverb and echo, you can make stepless adjustments.

Smart Layer

The smart:EQ owes its name to a special gift: its ability to learn. It recognizes disturbing resonances and phase cancellation, then offers you immediate, fully automatic solutions to improve single tracks or mixes. This lets you whip your audio material into shape, all within a few seconds. Owing to the complex filter forms, you can also quickly generate high-quality results in classic mixing and broadcasting. Last but not least, the smart:EQ is always the perfect choice when you want to present perfect video sound.

Who is Using entropy:EQ+?

Mixing Engineers

frei:raum is the perfect tool when it comes to complex or time critical mixing tasks. The highly specialized signal processing of frei:raum allows mixing engineers to easily improve the spectral balance of a whole mix or match the spaciousness of individual tracks in projects of any size.

Mastering Engineers

frei:raum's unique smart filters offer very precise and detailed filter curves for delicate mastering tasks. The filtering structures have been designed to preserve the naturalness of processed recordings and offer a warm, transparent sound.
