Detailed stereo extension

Developed for and tested by professional audio engineers, Stereoizer adds natural sounding width and depth to any audio recording, mono or stereo, leaving the inherent character of the original source intact.

Each of Stereoizer's algorithms adapts the characteristics of your audio using techniques in harmony with the way the human ear perceives sound direction. The IID (Interaural Intensity Difference), ITD (Interaural Time Difference) and Linear Width algorithms work independently of each other, giving you maximum flexibility. For more lively adjustments, use the IID and ITD controls; the Linear Width control is more subtle and, crucially, leaves the 'centre space' of your mix untouched.

Highly mono-compatible

Mono-compatibility is easily overlooked but is as important now as it has ever been. Many club and PA sound systems are still set up for mono playback, and the majority of portable radios and many TV sets are mono.

Stereoizer does not add any artificial reverberation, which means no disruptive artefacts such as doubling/chorusing effects or phase cancellation affecting your mono signal. The 'Collapse output to mono' option allows you to manually check mono-compatibility for your own peace of mind.

For mixing and sound design

Stereoizer can be used for introducing width to mono recordings, and to expand narrow stereo spectra, or conversely, to create or solidify a centre space in your mix. It can enhance the depth of your FX returns or reign in over-enthusiastic spot FX.

All of this whilst adding richness and gloss to your recordings, without having to resort to overcooked heavy EQ and/or compression.

For post-production and restoration

Whether restoring old recordings or optimising new recordings for louder playback, Stereoizer allows for natural-sounding extrapolation of your existing stereo image with neutral stereo expansion and contraction. You can re-balance the stereo field and re-introduce natural ambience which may have been lost during other stages of the production process.

Stereoizer also provides frequency-specific enhancements via psychoacoustic sweetening of frequency crowns. And if you’re happy with the mix as it is, Stereoizer can be used to firmly define the existing balance, with subtle taming of any eccentric material.

Stereo frequency analysis

Stereoizer's visual analysis displays how your stereo field deviates from the centre. This is measured against frequency from 20Hz to 22kHz allowing for frequency-conscious adjustments without referring to a separate analysis plug-in.

This helps to pinpoint areas of the frequency spectrum which may benefit from additional enhancement.

  • Expanding narrow stereo spectra
  • Introducing width to mono recordings

  • Taming eccentric material
  • Creating 'centre space'
  • Avoiding unnecessary EQ
