De-Esser is an AUv3 Compatible plugin for your favourite DAW such as Cubasis, Auria, AUM, Meteor, BM3 or GarageBand and does not work as a standalone app.

This is actually a trio of effects all rolled into a single package which are ideally suited but not limited to voice recordings (De-Esser, a Vocal Doubler and a Noise Gate).

This De-Esser is a great tool for removing sibilance from your vocals. Sibilance is the harsh over emphasising of phonetics such as 'ss', 'sh', 'ch', 'th' etc. which tend to be made worse during the recording process. This plugin has two modes of operation, 'standard' and 'multi-band' which can be used to effectively remove this kind of problem.

The standard mode emulates the ducking of a volume control just like mixing engineers used to do in the good old days, but in this case uses a compressor driven by a filtered band of the input signal that contains the problematic frequencies. This is a common and effective method which has been tried and tested for many years.

The multi-band mode uses a similar filtering mechanism to isolate the effected frequency band and applies a compressor to just that range in isolation. This method gives much more pleasing and natural results as it retains the overall volume level and only effects the specified frequency range.

We also included a Vocal Doubler which simulates a multi-track vocal recording. It uses sophisticated techniques that eliminates the phase cancellation issues associated with layering vocals in this way. You have complete control over delay time, levels and stereo field placement.

Finally this package incorporates a Noise Gate, to remove unwanted background noise from your recording. Fully configurable threshold, attack, release and dB reduction settings are available.

A visual frequency display helps you quickly find and isolate the effected frequency ranges which can also be turned off to reduce CPU load. 4 different visual modes are available to help visualise issues. A siblance filter preview button lets you listen to the problematic frequencies in isolation and a limiter is available to make headroom for the vocal doubler.

This is a great addition to our AUv3 plugin range which is heavily biassed towards recording of vocals.

Wow. It works.

It’s not a $300 rack unit but for under $10, it’s quite the App Store find for any DAW Dabblers out there. Surprisingly tweakable interface with a vocal doubler that’s fun but as always check the Mono mix before adding stereo ear candy to your final mixes. Know your way around GarageBand, etc before you plug this one in or you’ll be lost. Not the developers fault in that case.

Update. Although initially impressed at the potential of this little app I’ve since found the dents. Might be me but found no way to save preset. Might not matter except plugin always reverts to Female Multiband defaults. Please please at least make it save last setting as many of us are A-B junkies just trying to get a solid mix-sssss

A bit confused

I got the bundle of the 3. The problem I’m having is that they don’t work at all on any of the work I have already! So Of course I did everything from re downloading the plug ins and turned my phone off and back on and nothing. So I tested it one last thing. I recorded a test track just a few words and it worked like that! Can somebody please help me? Very frustrated.

Thank you-Ana

It works with Cubasis now

Thanks it works with Cubasis now but still can’t figure out GarageBand yet but I hope to get it very soon because I used GarageBand more than Cubasis

Developer Response ,

This plugin works fine in all those programs so maybe you should uninstall and re-install the app if it is not showing up. Please make sure you are running a late version of iOS and let me know the iPad model you are using please and I will take a look.
