Mult1Comp: Surround Multiband Compressor for Dolby Atmos and Immersive Mixing

Mult1Comp does three jobs.

Firstly, it is a surround multiband compressor, with up to eight bands on every speaker and a compressor on every band.

On linked object tracks it can split one source into up to 16 bands, one per object, so your renderer can place each range in its own pan position, acting as a frequency disperser, an alternative decorrelation method.

It can also act as a frequency router on a surround channel or bus, sending any band of any speaker to another speaker, which covers bass management too.

Surround multiband compression, 5.1 to 9.1.6

On a bed from 5.1 up to 9.1.6, every speaker splits into up to eight bands, the height speakers and the LFE among them. Every band has its own compressor: set its threshold in its cell, with its gain reduction metered beside it. Timing follows each band's range, so bass bands react slowly and treble bands quickly.

SPEED, RATIO, HEADROOM and COMP MIX shape every band at once, and COMP MIX gives parallel compression. IN drives every band harder together. Set up ALL once and every speaker follows it, then change any speaker on its own. Stereo pairs stay linked, or split a pair to set each side apart.

  • Hold down the low end of the surrounds without touching the front.

  • Control the top of the height speakers on their own.

  • Mute or solo any band or any speaker to hear what it is doing.

The display draws the compression as one curve across the spectrum, so the whole split reads at a glance.

Splitting one source across up to 16 objects

Put the same source on several object tracks and add Mult1Comp to each. The instances link automatically and each one takes a band, up to 16 in a group. Open any of them to see and edit the whole group's crossover and compression in one window, then place each object in your renderer as usual.

Every band has its own compressor here too, and the GLOBAL controls move the whole group at once.

  • Spread a pad with its low end in front, its mids at the sides and its top in the height objects.

  • Lift only the top of a source into the overhead objects and keep its body at ear level.

  • Automate the high band moving while the low end stays where it is.

The bands normally form a crossover that sums back to the source. Pull an edge apart to let two bands overlap or leave a gap between them. There are sixteen groups, each with up to sixteen members, and GROUP BYPASS compares the split with the source as it was.

Frequency routing and bass management

On a bed, any band can also leave its speaker for another one. Each band is compressed before it is routed, so it cannot pile up on a busy speaker when it gets loud.

  • Bass management to the LFE or to L and R, at 80 Hz or 120 Hz, with the factory presets.

  • Clean up the heights by sending their low end to the speakers below.

  • Fill the heights from the top of the front or surround speakers.

Sub bass synthesis on the LFE

Add a sub an octave below whatever reaches the LFE, for more weight from a thin source. Choose a sine, triangle or square character, or MULTI for a second, deeper sub, then set its tuning, drive and mix. LFE MASTER sets the level of everything leaving on the LFE.

Linear phase or minimum phase

LINEAR keeps every band time aligned, so bands from one source arrive together on different speakers. Its latency is around 85 ms, and the host compensates for it. MINPHASE has almost no latency, for tracking through the plugin. Slopes run from 6 dB per octave, gentle enough to spread a source without it sounding split, to 48 dB per octave for hard splits and bass management.

Presets and comparison

Equal Split presets from 2 to 8 bands, plus 12 and 16 on object tracks, and Bass Management presets at 80 Hz and 120 Hz give you a starting point. A/B/C/D slots compare four settings, and your own presets save from the header.

Built-in help in 22 languages

Hover tips explain every control, in any of 22 languages. Set the language once and every max1mus plugin on the machine follows it.

Format support

Bed mode on every layout from 5.1 up to 9.1.6, including the height speakers and the LFE. Object mode on mono and stereo tracks.

Frequently Asked Questions

What is Mult1Comp?
A surround multiband compressor for Dolby Atmos and immersive mixing. On a bed from 5.1 up to 9.1.6, every speaker splits into up to eight bands, each with its own compressor, and any band can be sent to another speaker. On object tracks, linked instances split one source across up to 16 objects by frequency, with a compressor on every band.
How many bands does Mult1Comp have?
Up to eight per speaker on a bed, set for every speaker at once or for each speaker on its own. In an object group, up to 16, one per object track.
Does Mult1Comp work with Dolby Atmos?
Yes. Use it on a bed from 5.1 up to 9.1.6, including 7.1.4, the height speakers and the LFE, or on mono and stereo object tracks to split one source across several objects by frequency.
How does the multiband compression work?
Every band has its own compressor, with its threshold set in its cell. Timing follows each band's range: bass bands react slowly and treble bands quickly. SPEED, RATIO, HEADROOM and COMP MIX set every band at once, and COMP MIX gives parallel compression. A routed band is compressed before it leaves, so it cannot pile up on a busy speaker.
How do object groups work?
Put the same source on several mono or stereo object tracks and add Mult1Comp to each. The instances link automatically and each one takes a band, up to 16 in a group. Open any of them to see and edit the whole group's crossover. There are sixteen groups.
Can Mult1Comp do bass management?
Yes. The Bass Mgmt LFE presets send everything below 80 Hz or 120 Hz from every speaker to the LFE, and set LFE MASTER to -10 dB to match calibrated monitoring. The Bass Mgmt L+R presets send the low end of the surround, height and wide speakers to L and R instead. Use a 24 or 48 dB per octave slope.
Should I use linear phase or minimum phase?
LINEAR keeps every band time aligned, so bands from one source arrive together on different speakers. Its latency is around 85 ms, which the host compensates for. MINPHASE has almost no latency; use it when tracking through the plugin.
Can I automate Mult1Comp?
Band gains, bed crossovers, each speaker's mute and solo, an object track's mute and solo, GROUP BYPASS, the high and low pass, IN, OUT, the GLOBAL controls and SUB BASS SYNTHESIS can all be automated. A group's shared crossover cannot, because it belongs to the whole group rather than one track.
Which DAWs and formats does Mult1Comp support?
Mult1Comp runs in Pro Tools, Logic Pro, Cubase, Nuendo, Fender Studio Pro (Studio One), Reaper and Pyramix. It ships as AU, VST3 and AAX for macOS, and VST3 and AAX for Windows.
