M-ImagerNEW!
M-Imager is a spectral stereo expander built for mastering-grade precision. Its phase-only, time-varying decorrelator creates natural width with razor-sharp transients, perfect mono compatibility, and no colouration. From stereoising mono tracks to enhancing full mixes, M-Imager delivers unmatched stability, depth, and tonal transparency.
Smart solution for creators
Unmatched width, untouched tonal balance
Precise Phase Manipulation for Transparent Stereo Imaging
At the heart of M-Imager is a custom phase-only, time-varying spectral decorrelator. The phase rotations it applies are engineered to perfection, preserving transient integrity and ensuring that punch and timing stay intact. And the side energy is continuously aligned so left/right balance never drifts.
This guarantees that your mixes will translate flawlessly across playback systems, from club rigs to headphones. Push width confidently, knowing you will always get stable, natural stereo image without chorusing, flanging, or that hollow "phasey" sheen.
Advanced Stereo Field Sculpting
Perfect your stereo image with M-Imager's Side Channel Dynamic EQ. It shapes the stereo content with a gentle linear-phase equaliser, while keeping the centre unchanged for perfect mono compatibility. Firmly ground the lows in the middle, while making the sides breathe with the dynamics of your track!
M-Imager's Side EQ lets you gradually roll off the signal to mono below a set frequency to make sure your bass has maximum impact. And the dynamic high shelf makes it easier than ever to dial in stereo width that follows the dynamics of your track.

Sound Examples
Key Features
Widen
“Widen” controls the amount of the new Side signal generated from the original Mid channel. If the plug-in input is mono, setting “Widen” above 0% will expand it into stereo. If the input is already stereo, the generated Side signal will be added to the original Side channel, increasing the stereo width of the audio.
Widen Range
“Widen range” targets the part of the spectrum that will be affected by stereo expansion of the “Widen” control. It limits the frequency range in which the new Side signal is generated.
Stereo Field Visualiser
Stereo field visualiser is a realtime decibel-valued goniometer that gives a comprehensive overview of your track’s stereo image. It plots the momentary level of the left channel against the right channel, so you can see the width and balance of your track.
The width of the goniometer image represents the amount of difference between the left and right channels: wider image means more stereo spread. Therefore, a mono signal is represented by a narrow vertical line on the goniometer as it lacks any stereo width.
Mid Gain & Side Gain
“Mid Gain” and “Side Gain” give you direct control over the levels of the Mid and Side channels.
“Side Gain” affects both the original Side signal and the new Side signal generated by the “Widen” control. Boosting “Side Gain” increases the stereo width of your track. Cutting “Side Gain” results in a narrower stereo image. “Mid Gain” is the only control that affects the Mid channel.
Side Channel Dynamic EQ
The “Side Channel Dynamic Equaliser” section of M-Imager controls the gentle linear-phase EQ that is applied just to the Side channel. It affects both the original and the generated Side signals.
Side Channel Dynamic EQ allows you to further sculpt the stereo image of your track while keeping the Mid channel unchanged for perfect mono compatibility. Optionally, you can use it as a dynamic EQ with the amount of boost or cut depending on the level of the Mid channel.
EQ Mono Cutoff
“Mono Cutoff” sets the frequency below which the output will be gently rolled off to mono. This is achieved by applying a 9 dB/octave high-pass filter to the Side channel. This control can be set to “Off”, in which case no attenuation is applied to the Side signal.
Use this control to keep the low-end energy of your track grounded in the middle of the stereo image.
EQ Frequency
The “Frequency” control sets the frequency of the high shelf EQ applied to the Side channel. Frequencies above this will be boosted or cut depending on the “Gain” value.
EQ Gain
“Gain” adjusts the gain of the high shelf EQ applied to the Side channel. It determines how much the frequencies above the “Frequency” value will be cut or boosted. When the “Threshold” control is enabled, “Gain” sets the maximum amount of boost or cut that can be applied by the dynamic EQ.
EQ Threshold
“Threshold” enables dynamic operation of the Side Channel EQ. It sets the threshold (in decibels) that the Mid signal needs to exceed for the full amount high shelf “Gain” to be applied. When the Mid signal level is below the “Threshold”, a proportionally smaller amount of gain will be applied.
Side Channel Dyn EQ display
Side Channel Dynamic Equaliser display shows the current EQ curve applied to the Side channel and lets you intuitively set “Mono Cutoff”, “Frequency”, and “Gain” parameters.
Solo Mid & Solo Side
“Solo Mid” and “Solo Side” let you listen to just the Mid or just the Side channel in isolation. Use these controls to hear exactly what the plug-in is doing to the stereo image of your track.
Output control
“Output” controls the amount of clean gain applied to the processed signal.
Internal On/Off Switch
A dedicated bypass/on control allows enabling or bypassing the effect without clicks or artefacts, unlike toggling from the DAW directly.
Scalable user interface
The interface can be scaled from 80% to 150%, allowing you to personalise the GUI for your workflow.
Undo/redo options
Built-in Undo and Redo provide safety while working. You can revert or redo changes easily.
Tooltips
An optional 'Tooltips' feature shows short descriptions when hovering over controls. Great for quickly learning the interface.
Frequently Asked Questions
M-Imager achieves the widening effect without the usual artefact-prone widening methods like delays, frequency panning or static convolution. It uses an advanced phase-only decorrelation algorithm that perfectly preserves the original tone, dynamics, and transients. The result is a natural extension of your audio into the stereo field that is completely mono-compatible.
No. M-Imager expands the stereo image without adding any colouration. The tonal balance of your track remains untouched, so the result is a natural, transparent extension of your audio rather than an exaggerated or artificial effect.
Yes. M-Imager was designed with mastering in mind. Its transparent processing and continuous side-energy alignment guarantee a balanced stereo field that translates cleanly across all playback systems, from club systems to mono speakers.
The Side Channel Dynamic EQ allows precise sculpting of the stereo content. You can keep low frequencies firmly grounded in the centre while letting the upper mids and highs breathe with the dynamics of your track. This creates evolving and reactive width without compromising low-end stability.
No. The algorithm was engineered to preserve transients with absolute accuracy. Punch, timing, and groove remain exactly as you set them, even when applying extreme width, The result is clean, stable imaging with no smear or softening.
