Auria FX & Plug Ins Review – Part 3 Mastering

I want to start off by saying thank you to everyone who sent me such inspiring emails about this series of reviews.

Part – 3 Mastering Plug Ins

In this third installment I will focus briefly on each of the following FabFilter Plug Ins for the purpose of Mastering.
ProC, ProQ, & ProL.

As good as all of these FabFilters are, they become useless if what you are using to hear the amazing results they are capable of producing, through just ordinary headphones or cheap speakers. It probably goes without saying, but excellent headphones and decent monitors are very important. We can’t all have studio monitors, but having at least very good headphones are a must. If you’re using the Apple ear buds that came with you’re iPod, or anything from the general selections of headphones from the electronics store, stop now. Go look at, listen to, and then buy some good ones. The differences you’ll hear are night and day. That’s just my opinion for what its worth.
I’m using Sennhieser HD 558 around the ear headphones. They were about $200 and sounded equal to all the other headphones I tested that cost hundreds more. For monitors, I am using some Altec Lansing speakers with a powered sub woofer, Ive had for ages. They have a very clean sound, but not quite up to “studio monitor” levels. They do get the job done in the limited space I have.


FabFilter Pro C
$29.99 via IAP


This easy to use and great sounding compressor is a significant step up from the free compressor option built into Auria. Visually far more appealing at the very least. As is the case with all the FabFilters. ProC has 3 styles: Clean, Classic, & Opto. Hard, Soft Knee, Side Chain Supported, & Auto Gain & Release.
I found ProC to be more useful over the built in compressor and maybe its just me, but it sounds tighter. The moving compression level display has customizable curves. Seeing and hearing the work makes all the difference.
If you want to fine tune your sound at every point, you can, and ProC is very reliable. There are presets included as well that are set perfectly for each of the selections. Undo, Redo options and a before/after selector are also included.


Program dependent attack and release curves
Large input, output, and gain change meters with different scale settings
Active knee display
Super-fast attack times

If you are just getting comfortable with using compression this will be a great plug in to begin with. If you have high expectations and want the very best compressor, this it. Whatever the need this sounds extremely good.

FabFilter Pro Q
$29.99 via IAP


A good EQ is essential, if not the most important mastering tool. This 24 band, touch manipulated EQ is a godsend. Zero latency or linear phase with adjustable latency. It has all the filter shapes with variable DB/Oct slope selections you’ll need and is so easy to use. Make a mistake or change your mind theres a undo & redo option. Before and after toggle, left/right independent channel EQ’ing, real time frequency analyzer with pre & post EQ metering. Several perfectly tuned presets to choose from and very detailed parameters to (wait for it) tweak. Notching out a hot frequency is no problem, and with automation support there’s nothing you can’t manipulate or correct with high quality results.

Up to 24 EQ bands
Filter shapes: Bell, Notch, High/Low Shelf, High/Low Cut with 6, 12, 24 and 48 dB/oct slopes
Intelligent solo mode makes it easy to tune notch filters and hear the effect of a band
Different display ranges: 3 dB and 6 dB ranges for mastering, 12 dB and 30 dB for mixing
Smart Parameter Interpolation

From hi, low shelving, stereo enhancements, frequency fixes, to wild filter FX like “telephone” sounds, and everything in between are possible. This is probably the single most necessary Plug In, and sounds noticeably better than the built in EQ. Which isn’t too shabby to begin with.
Yes, you need this. No you won’t regret it.

FabFilter Pro L
$39.99 via IAP


Another essential mastering and mixing tool is the “Brickwall Limiter”.
ProL has multiple advanced algorithms, features, and accurate metering.

Great transparent sound combined with maximum loudness
Four different limiting algorithms, all with their own character
Highly accurate output and gain reduction metering
Adjustable meter scale, including K-System support
Adjustable look-ahead, attack and release settings
Separate channel linking for both the transient and release stages
Advanced dithering with three different noise shaping algorithms
Inter-sample peak detection


ProL is designed to be very accurate. It has up to 4x oversampling, but is very demanding on device resources. Of the 3 FabFilters looked at here, this one can put the greatest burden on your device. When the need for a really good limiter comes up, there just isn’t anything better. This particular FabFilter might be more niche than absolutely necessary. I mean that the included brickwall limiter does a fine job, but this is really specialized and more for experienced sound engineers to be fully appreciated.

Each of the FabFilters looked at here are of the highest quality. Certainly comparable to most available on desktop DAWs. They did an amazing job with these to really offer the very best tools for serious users who don’t want to compromise. They all have undo and redo, support for automation, touch support, and have extensive help support within.

Again, I hope this was helpful, and sorry it took so long to get this part 3 finished.

Part 4 coming up soon.

Auria FX & Plug Ins- Review part 1- Reverb

Starting here with the Auria Reverbs I will offer my thoughts on both the included, and the extra Auria FX & Plug Ins. I don’t have all of the Plug Ins yet, but I will eventually. That said there’s too many to write one huge review. Since I make ambient electronic music Reverb is a very important effect in my work. It’s an effect that has so many uses and is widely used by most musicians. A seemingly common staple in any FX library, Reverb is anything but common. It’s like Reverb is an instrument itself. Most of the Reverbs found in iOS are very limited, and low quality. That’s understandable as it is a big power hog and our devices improving as they are, still struggle with processing even very basic low to medium quality Reverbs. WaveMachine Labs with Auria and its PSP Plug Ins deliver much improved quality in the Reverbs offered rivaling ( still have a ways to go ) even some desktop versions costing tons more. I’ve tried nearly every available Reverb on iOS, including recent high profile releases like Cubasis. Incidentally having recently given Cubasis and its FX a test drive is still fresh in my mind, and its Reverb was sorely lacking. Whether old or new most iOS Reverbs left me unsatisfied. For now at least the highest quality Reverbs anywhere in iOS are living inside Auria. They are without peer.

Lets start with the ClassicVerb


A better, basic Reverb option than most standard Reverbs in the vast majority of music apps. Simple controls for the overall effect much like what we’ve seen a lot of. It has a warmer feel with a decent tail and good stereo spread. Best used for recordings that just need a little more depth and life, nothing too dramatic. A good choice to conserve resources.



This is probably the best reverb option on iOS that doesn’t cost extra. It uses high quality samples of specific types of reverberations called Impulse Response. The I.R. Library included has many very nice sounding reverbs that when used with your audio convolutes the mix. Hence the name. The “I.R. Library” installed is big enough, but you can also buy I.R library packs to further expand on your available options for an enormous (Hundreds and hundreds) variety of Reverb effects.


The additional I.R. ( From MoReVox at $5.99 via IAP) packs each offer an expanded collection of specialized recording types to use. From short or long classic plates, warm, creamy, springs, and small rooms, to cold long hallways, Arctic, cathedrals, deep space, modulated, and tons more can be had. All high quality and original sounding. Rich and expansive. Each I.R. resembles presets for the most part somewhat making up for the limited controls. This is the reverb of choice surpassing anything else on iOS by leaps and bounds. Best used for your higher quality reverb needs to suit specific audio scenes. It should be expected that it comes at the expense of being a power hog. There is a “Low CPU” mode but that reduces the depth and quality a lot as well as reducing its burden on CPU. Freeze the track if you’re going to use it more than once as an insert.

ClassicVerb Pro


For $9.99 via IAP you can have a much better version of the included ClassicVerb. Is it worth it? I really think so.
It adds more controls such as HiPass, LoPass, Split, Tone, Mix, Output, Spread, Time and Pre Delay providing an excellent level of control over your sound. It has some quick presets and you can save your own tweaked concoctions. Overall it sounds better than the ClassicVerb but not as varied as the convolution reverb with its huge library of I.R. options. This is a great classic reverb option sounding much better than any other of its kind offered in any iOS music apps. A superb choice. Worth every penny.



A unique resonant reverb effect that not only offers a high quality classic reverb spread, but also controls elements like tune, detune, modulation, and transposition of the reverberations. It has A&B alternate setting controls for “damp” and “Time” with “Freeze” for dramatic effects.
Very different from the other reverb options, PianoVerb2 (a new improved and advanced version of the original free PianoVerb) uses 12 resonant filters that behave much like piano strings. Making ghostly wide, modulated sounds with lingering effect similar to piano sustain pedals is just one of its many possibilities. You could really go wild making highly unusual detuned and transposed reverberations that the others can’t. Whatever you do with this, it will fill your ears. This is one very nice, and interesting plug in!

Not like a convolution or classic reverb, PV2 is quite capable of adding depth to relatively weak sounds but with that extra bite of resonance. It is really cool and different.
You’re robbing the Auria store by only paying $9.99 for this weird reverb. Also a bit of a power hog.
By PSP Audioware

That concludes Part 1. Just a couple notes.

The PSP PianoVerb2 in Auria is not the same as the older classic PianoVerb free version. It is a more advanced and improved version of the classic original. I know, thats obvious and clearly says “PianoVerb2” in the review but people don’t always pay attention details and are eager to correct. Comments welcome, and so are corrections, so long as they are actually correct.

All of these were tested thoroughly. The best test for Reverb is to take a mediocre sounding, single note, dry recording. Then duplicated and spaced appropriately apart to fully experience the depth and quality. Then I added more recordings to other tracks trying each of these at various settings, I.R.s etc, solo and mixed. Each of these performed uniquely well. That’s how I tested them anyway. Try your own way, nothing beats experimenting yourself.

I hope this might help or be of some use. Let me know and I’ll keep adding to the series.

Thanks for reading.


UPDATE 1-26-13

PSP SpringVerb2


I suspect this will happen again. I mean having to add a newly released plug in for the various categories as this goes on. A welcomed challenge for sure.
SpringVerb2 ($9.99 via IAP) arrives to expand on available Reverb options in Auria. Like PianoVerb2, SpringVerb2 offers a unique and unusual reverberation effect. SpringVerb2 is an emulation of hardware spring reverbs. The sound it makes may be what you would expect, a springy, boingy, mechanical type. It can be used just as well as a pretty nice standard reverb, but its strength is in its odd boing sound that when coupled with fast attack instruments, synths, or especially guitars brings something very different to the Reverb table. A cool effect on transients, or repeatable with a superb spread range. Controls over the musical elements of the effect such as Diffusion, HiPassFilter, Presence and more put you in the pilot seat with plenty of room to experiment. See above screen shot for all the controls.
Adjustable 2-4 springs variations, and a solid amount of controls to make soft, modest boings, to long mechanical springs reverberating in some alien spaceship machine shop. This one has its own character.

Coming up soon Part 2- Delay/Chorus. A look at all the Delay/Echo and Chorus related FX.

Special thank you to WaveMachine Labs granting me access to all these amazing tools. I am eternally grateful. Furthermore, and just as special, thank you to everyone for the private messages, posts, comments, tweets, etc, encouraging me to continue with this series. It may end up being an endless endeavor if they keep adding new things to Auria’s store. I can’t say I’d have any objections, keep ’em coming! Ill do my best to keep up.
