## What is De?

De-Esser is an AUv3 Compatible plugin for your favourite DAW such as Cubasis, Auria, AUM, Meteor, BM3 (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.

### 1/5 — Não limpa a frequência como um De-Esser deveria

*2025-12-31*

Promete reduzir sibilâncias mas não faz, infelizmente ainda não temos nada no mundo mobile que possa fazer isso. Usei por aproximadamente duas semanas para ver se não era meu ouvido, mas, de fato, não limpa. A mix fica suja e ainda tira harmônicos dos instrumentos ou voz, tornando o som opaco.

### 5/5 — Excellent collection of  apps

*2025-04-24, version 1.01*

I have the vocal bundle and  have used the De-esser  component to clean up some recordings  produced in the late 90’s.  I’m very happy with results. 🫡👍🎶🙏

### 1/5 — Developer inattentive.

*2025-02-14, version 1.01*

This developer is impossible to get a hold of, and they have not shown any indication of plans to update some of their paywalled products, rendering them prone to obsolescence. I would recommend not purchasing from them, as it appears that all of your purchases will become useless and obsoleted once other app developers and Apple update their own products.

### 5/5 — Work’s absolutely fine!

*2023-07-25, version 1.01*

Those are complaining about this app not working properly, it’s absolutely ok and running smoothly, just be a you dont have the 5 minute to read the manual or the description, it isn’t the developers fault. Kindly show a little bit support to the devs. They are trying passionately and sincerely to support this iOS music platform. Regards.

### 1/5 — Disappointing

*2023-05-24, version 1.0*

Needs to be updated as it doesn’t work anymore.

### 3/5 — Sounds Great But Doesn’t Save Settings

*2023-01-16, version 1.0*

It would be 5 stars if the settings would be saved when I re open my daw. Every time I open my project I have to reset my settings on this app. Please update this issue and then I will give you the 5 stars that you deserve for a great sounding deesser!

### 1/5 — Why don’t you they offer even basic install instructions?

*2022-09-01, version 1.0*

I got this working once, after searching the web for an hour, and it was pretty good, but I can’t rate it if it’s unusable at this point.  Add some instructions!

### 1/5 — Don’t work at all

*2022-04-03, version 1.0*

I want my $8.99 back (Edit) I still want my $8.99 back don’t trust these fools their app don’t work at all

### 1/5 — Crashes A lot With GarageBand

*2021-12-08, version 1.0*

Bought this a year or so ago, crashes a lot with GarageBand now I’m scrambling looking for a new De-Esser

### 1/5 — Does the job

*2021-12-03, version 1.0*

I have to reset the settings every time I open my project in GarageBand. It defaults to Female standard. I have to change it back every single time. Will upgrade to a 5 star if the problem is fixed.
