FAC Transient as is suggested by the name is an outstanding dynamics processor providing precise design and control of the attack and sustain stages of your instruments. Transient designers or shapers are often associated with drum enhancements and only the best of them are versatile enough to suit most of the scenarios. Of course, you know that FAC takes pride in ensuring versatility in its product line, providing subtle to drastic changes. FAC Transient is no exception to the rule!

To meet this objective and to be ready for all the situations: drums, guitars, bass, vocal and much more. FAC Transient includes, in addition to the classic amplification or attenuation of the attack and sustain portion of your instrument, a fine control of the detection circuit involved in the processing.

Without going into technical details, there are three envelopes built from their respective detection circuits. The first one is the contour of the input signal, this includes similar processing available in Maxima and brings you control of the treshold, time and detector algorithm. The second and third one define the contour of the attack and sustain portions and brings you a total control of the depth and duration of each stage.

FAC Transient gives you all you need to design the shape of your instruments and provides them the place they deserve in your mix.

FAC does it again with a pro plugin that’s incredible bang for the buck


The past three years I’ve dedicated myself to using the iOS music production format exclusively in my home studio has been one of the most most rewarding experiences of my musical life. I heard the guys warning me that abandoning my laptop with Pro Tools would be a mistake and knew that there weren’t a lot of apps & plugins on iOS, even ones that I had taken for granted on desktop. But Feb. of 2015, when I first got my Air 2 & bought Auria to now in Feb. of 2018 are night & day. When a dev like FAC puts out a pro level transient designer like this, that’s in the same league as those on desktop, the only thing holding one back is their talent and skills. This app can morph drum loops into entirely different flavors, on bass it can totally alter the timbre, etc. it does so much more than just fast attack compressor stuff, it really rewards experimentation. Great job Frederic, highly recommended.

Magic Sauce! Seriously, this app is mix magic! Must Buy!


At first i was like, how will i use this app, then the need came when i was playing back Rock Drum Machine track and didn’t like the room, but i liked the drums, so i thought, this is the perfect time to test FAC Transient. As soon as i loaded it in Auria Pro, as an AU insert effect on the drums track, dialed up the No Room preset, and tweaked it just a bit, OMG!!! The drums came alive! The room was completely removed, leaving the drums to stand out so much more, and without affecting the cymbals etc! This is truly amazing!

Added FAC Maxima to the mix and dialed up the Drums Classic preset and my jaw hit the floor!

If you are on the fence about getting this app, let me just say that this is truly a must have app for any serious IOS musician. It’s AU and can have multiple instances of it, with hardly any CPU hit. It is incredible! Buy it, it will bring a huge smile to your face when you listen to what it can do in your mix.

The developer is second to none, and always attentive and responsive with user ideas and support issues. This is one of the main reasons apps like these are so successful, it’s the developer support that makes the difference, and Fred is the man when it comes to attention to detail and performance.

I highly recommend this app!


iOS music production is getting SERIOUS


The recent addition of FAC Transient has taken music production on the iOS platform to another level!

The description of a transient effect sounds somewhat esoteric and frankly not very sexy as far as musical effects go. But the ability to sharpen or reduce attacks and adjust sustain will provide a wealth of tonal opportunities, not just on drums.

The developer of this app is very approachable and supportive. I wholeheartedly recommend this app!
