Pulsar Modular P21 Atlas

P21 Atlas

Atlas delivers coherence. Loud, without the peaks being flattened.

A master-bus stabilization limiter, not a peak-catcher. The engine holds the program coherent across its full length, so elements stay where the mix put them. Nothing jumps. Nothing drifts. The frame holds. Stereo through 9.1.6, the program lands as one statement.

Editions

Choose your stage.

The same engine drives both editions. Atlas Stereo operates on mono and stereo buses. Atlas Immersive operates on every format, from mono/stereo through 9.1.6. The edition is set at purchase, and Stereo upgrades to Immersive at any time.

Atlas Immersive

Every channel format, from mono/stereo through 9.1.6. The full engine.

• Mono, stereo, 5.1, 7.1, 7.1.4, 9.1.6 and every format between
• Dolby Atmos, DTS:X, Auro-3D delivery workflows
• Shared gain reduction preserves the spatial image
• LFE monitored, never processed; per-platform delivery cues
• Everything in Stereo, on every channel

Atlas Stereo

COMING SOON

Mono and stereo buses. The same engine, one stage.

• Operates on mono and stereo buses
• The identical engine: Composure, GRIP, Energy, Foresight
• Same preset library, tuned on real material
• Same metering panel and MATCH comparison
• Upgrades to Immersive at any time

If an Atlas Stereo license loads on a multichannel bus, the plugin recognises the unsupported layout and passes audio through unchanged. Start with Immersive today, or wait for Stereo.

What Atlas delivers

Three consequences engineers value.

Atlas does not reveal itself by adding a sound. It reveals itself by holding the program together. A mix made from stems recorded in different rooms presents as one performance in one space. A film scored from library cues, dialogue, and sound design lands as one continuous world.

Transients land where the mix put them.

Kick and bass arrive together when they are supposed to. Vocal consonants stay attached to their vowels. The pocket the recording captured is the pocket you hear. The dynamic relationships the recording captured are preserved.

Loud, without flattened peaks.

The program is delivered loud, but the peaks have not been flattened. Loudness arrives without compression character. Atlas leaves the program with headroom intact, ready for a dedicated clipper downstream if clipping character is wanted.

Quiet passages remain quiet.

Conventional limiters lift the noise floor between vocal phrases, between drum hits, after a cymbal decays. Atlas does not. The breathing engineers learn to tolerate on conventional compressors is simply not present.

The five-minute recipe

Five minutes is enough to hear it.

Put familiar material on your master bus, bypass everything after Atlas, load the preset that matches your source, then activate MATCH and toggle BYPASS at equal loudness. That is the whole test. The interactive walkthrough takes you through each step and what to listen for.

Atlas Immersive

One program. Every format.

Atlas Immersive treats every main channel of a multichannel bus as part of one program. The engine analyses all main channels together and applies the same gain reduction to all of them at every sample, which preserves the spatial image. Sources do not move within the soundfield as the engine works.

• MONO
• STEREO
• 5.0
• 5.1
• 7.0
• 7.1
• 5.0.4
• 5.1.4
• 7.0.4
• 7.1.4
• 9.1.6

The LFE channel is monitored but never processed by the engine. The panel adapts to the bus format at instantiation: LFE PEAK appears on every layout that carries an LFE channel, the stereo CORR row is hidden on non-stereo formats, and the window sizes itself for the layout.

Preset library

Tuned by ear, on real material.

The preset names describe the source character a preset is calibrated for, not the genre as a category. Choose by the source-character description, not by the name alone. Each preset is a starting point, not an ending.

Default

Universal start on unfamiliar material

Country Acoustic

Sparse, dynamic, vocal forward

Sparse Acoustic

Solo or near-solo, no rhythmic density

Country Pop

Pre-treated, moderate transient density

Rock Solid

Full-band, vocal above the arrangement

ATMOS Launchpad

Atmos master into final stabilization, ~-18 LUFS-I

K-Pop Verse

Wall-of-sound, verse density

K-Pop Chorus

Wall-of-sound, chorus density

Orchestral

Naturally captured, wide dynamics

EDM Depth

Already mastered, loud and dense

Hip-hop

Kick-led, sub-bass dominant

Jazz

Acoustic ensemble, wide dynamics

Drum Bus

Transient-dominated stem, not full program

Drum Control

Drum bus, sustained kit presence, articulated hits

Bass Elec Punch

Electric bass bus, sustained low end and punch

GTR Elect grp

Electric guitar group, transients preserved

Vocal

Vocal bus, firm articulation, reactive catching

Bus and group presets

Atlas also works on individual buses and groups as a stabilizing bus compressor: Gain at 0, Ceiling lowered until the engine engages, level recovered with TRIM.

Testimonials

Trusted on real masters.

• “P21 Atlas simply does what it promises. The way it stabilizes the music feels very natural and groove-focused instead of just smashing everything flat like a typical limiter. What I like most is that I can push masters loud while still keeping them open, punchy, and groovy. It controls dynamics in a really smooth way without killing the movement or energy of the track. Definitely a very impressive tool!” — Adham Farid, Record Producer / Audio Engineer Uzi · Aksan · Modd · Selin · Particles · Valfi
• “P21 Atlas is able to let the sediment and dust that were lifted during the master's processing settle back to the seabed, restoring depth, brilliance, and microdynamics that over the years we have learned to lose as the price to pay for a good master. I discovered this applying P21 Atlas to the electronic music I'm most familiar with, but once you learn to notice it, you feel the need for it everywhere.” — Alessandro Picciafuochi, Mixing & Mastering Engineer Robert Miles · Satoshi Tomiie · Alex Neri
