  • Great Plugin

    Normally when I record classical music, I use a stereo mic'ing technique. But for a recent concert video I had to mic a flute and guitar duo individually. It was a good sound, but it didn't have the sense of space and depth I would have gotten with a stereo mic. Mono Upmix came to the rescue. Immediately I got the sound I was hoping for. It gave the recording space and depth. It was very real in its quality and I will use it without hesitation any time a recording needs it.
    Having experimented with other music, such as a jazz recording I did, I don't think it gave the same benefit as all the instruments were closely mic'd and it didn't seem to fit the aesthetic, but that doesn't take away from Mono Upmix being a wonderful tool.

    Have used this for about a year now and it just works wonders on almost any mono material. Earlier I used to turn to a slew of plugins for the same effect. Now i just dial in the channel EQ and add this last to help positioning the source.
    I also pretend my mixing translates better now.
    I highly highly recommend this.

    Very much needed for close miked sources, almost an ambience reverb, but still not that much, waited for something like that for years. Pity , that it behaves so bad in Digital Performer, the DAW gets confused somehow and can't identifiy stereo or mono attributes, so it gives an error when I want to place something else after or even before it in inserts.

    Extraordinary algorithm that obviously shines in audio post but is fantastic for music production as well. Very realistic in creating subtle spaces for instruments that should stay in the background – forget traditional panning and reverb… this is the way to go.

    Good and fast plugin not just for the bold imaging but for leveling (adds each sound unique space without diving in physical modelling like the use of EQ and reverb). One of the top plugins for me to get extra clarity and depth from mono sources in a trustful way. Very helpful UI visualizing things where the soundsource is placed and how much blur is applied. For that reason earns a 5 s rating and without overhyping it really. Could live without it but it makes the whole process more simplified.
  • A different (and excellent) mono to stereo plugin

    One of the best Mono to Stereo plugins I've ever heard. It spreads the signal (in both panorama and depth) in a more natural way than most M > S plugins. It adds a nice sense of space or natural ambience while avoiding tricks like M/S re-balancing or frequency spreading common to older & more primitive plugins. An easy way to get some spread without relying on short reverb or delay, and the ambience it does add is smooth and natural. The HF rolloff tied to the depth axis is scaled well and transients get softer, much like moving a mic further from the sound source, which adds to the realism.
    The only issue is that the input signal must be panned hard left for it to work properly; this prevents instant On/Bypass comparisons; but this is a minor shortcoming.
    It may not be the perfect Mono to Stereo plugin for all occasions (sometimes the added ambience is inappropriate for the material), but it is definitely in my top three.
  • Can be more convincing than reverb...

    A great “secret weapon” for adding some depth and space to mono sources without necessarily adding more reverb.
    Note that, like other “stereoisers”, extreme settings can mess with left/right phase coherence, so use with caution. That said, it sounds nothing like any other “faux stereo” effect I’ve ever used. Wonderful realism.
  • Forget reverb. This is how you put an instrument in a physical space.

    I'm a big fan of bx_stereomaker so I thought I'd try this one out too. Turns out, it's quite different, but in the best way.
    I love this thing on mono acoustic instruments in a dense mix. Particularly banjo and mandolin. You can really hear the depth and positioning this plugin allows. I'd much rather use this than a reverb for putting an instrument "in a room" or in it's own physical space.
    Another fun trick: try automating the distance control during solos. It sounds very natural bringing an instrument to the front for a lead, then pushing it back afterwards. I'm in love with this thing.
    Very powerful. A must-have for me.
