Compressors are probably the most used audio processors and you surely know what it's all about and how it can help to control the dynamic range of your audio signal. So let's get straight to what makes FAC Medusa a new versatile and characterful compressor!

FAC Medusa combines different dynamic processors into a single and easy to use unit, the input signal flows along the following stages:

1) "Pre-amp with tone control and saturation circuit" The input signal is split into three bands of frequencies (Low, Mid and High) according two adjustable crossover points. Setting the level and the saturation amount of each frequency band will definitely make the effect more natural or characterful.

2) "Compression" In addition to the usual controls you may expect, FAC Medusa also provides two types of compression. Downward compression, which is obviously the most common, decreases the level of audio signal above the threshold. And also Upward compression which is less known, despite powerful, and increases the level of audio signal below the threshold. The compression can operate either on the SUM of the frequency bands (L+M+H) or on each frequency band coming from stage 1.

3) "Parallel compression and Brickwall limiter" The master Brickwall limiter is optional and will ensure that the output of stage 2, possibly blended with the original audio signal, remain under control. The limiter comes with threshold and release time controls.

As you have realized FAC Medusa has many faces: gentle, natural, or aggressive and colorful. Choose the one you want and be prepared for an exciting sound design experience. Whether you are a budding music producer or passionate amateur musician in any genre, you will definitely find a happy use for it!

- AuV3 and Standalone App
- To use the sidechain and/or to output the additional three bands, you need a host able to provide to the AuV3 an input bus and three additional output busses

### 5/5 — a top-notch dynamics processor

*2024-02-27*

This compressor is solid, and it gets the job done. The sidechain capability is great, and saturation by band is an added bonus. I’ve found that boosting saturation in the midrange adds a ton of warmth and character to my audio source. It’s also visually pleasing and very easy to use. Another fine app by FAC!

### 5/5 — Essential

*2024-02-25*

I use this on everything! Versatile, unique and sounds excellent. Lots to learn but start with the great presets 👍

### 5/5 — Medusa is killer

*2024-01-13*

If you wanna make something stand out, get Medusa. And the separate band saturation, just the icing on top

### 5/5 — Landslide!

*2023-03-15*

The most addictive dynamics processor on iOS imho.

### 5/5 — Spice up any audio

*2022-11-27*

Awesome tool for any iOS music producer.
Probably my favourite compressor because of its sound shaping and enhancing qualities. I like to use Medusa after Transient Designer, another super useful tool from FAC.
Five stars!!!

### 4/5 — Great but needs a few updates for 5

*2022-10-23, version 1.0*

Great tool to get your drums banging in no time. compressor,eq and saturator all in one and good solid sound. As a new release it is lacking polish though. Minor things to make the workflow more efficient. For example it is still missing things like double tap to reset knobs or numeric boxes. So yet not a 5 for me.

### 5/5 — Tremendous

*2022-10-16*

Saw this demoed on The Sound Test Room where Doug raved about it, a couple of minutes in and I pre ordered it. Tis most wondrous.

### 5/5 — Cool app

*2022-10-07*

Excellent stuff

### 5/5 — Another winner

*2022-10-04*

I admire this dev very much, works hard, super pro apps ! Gotta get em all! Great edge and sound with this, works great on drums, synths, and instruments!

### 5/5 — More, not the same

*2022-10-03, version 1.0*

Most IOS music makers already have half a dozen compressors. So why get this one? Because, FAC Medusa’s x-factor is what is described as ‘colourful character.’ In other words, it manages to sound unique, and distinct from other excellent compressors such as those by Tone Boosters, Fab Filters, etc. Quite often it is such distinctions that make the difference as to whether a song appeals to many ears. So if you have the cash, this is an app well worth the investment. And it’s fun. (-:
