Complete Mastering System For iPad

Positive Grid releases Final Touch   25-Mar-14

Positive Grid has released Final Touch which they describe as a complete mastering system for iPad. They say that, combining Maximizer, Pre and Post Equalizer, 4-Band Dynamics, Stereo Imager, Reverb and Dithering into one integrated app, it gives your mixes a huge, balanced, polished and professional sound. Here's Positive Grid's detailed description:

Pre and Post Equalizers

The Pre and Post Equalizer modules are typically placed before and after the Multiband Dynamics (Multi-Dyn) module, respectively. A typical application is to boost with the Pre EQ in a specific band while compressing dynamics in the same band using Multi-Dyn, thereby increasing sonic density in that particular spectrum. The Post EQ can then be used to put the finishing touches on the spectral balance for the master. Both the Pre and Post EQ offer eight independent bands, each providing a choice of five different types of parametric filters: Hi-Pass, Low-Shelf, Peak, Hi-Shelf and Low-Pass. These high-end filters exhibit the overshoot response of classic analog hardware. Each band can be independently bypassed. The Pre and Post EQs can operate in either stereo or mid-side mode, and you can link the left and right channels or the mid and side channels for simultaneous adjustments. Linkable output-gain faders allow you to adjust the relative balance of L/R and M/S channels at the output of the module and are accompanied by multi-colored ladder meters and fader and level readouts.


Multi-Dyn is a highly flexible stereo/mid-side multiband compressor/limiter. Each of Multi-Dyn's four bands can operate independently on the mid or side channel and offers separate and continuously variable attack, release, threshold, ratio and output-gain controls. Tapping on the All button for any control allows simultaneous adjustment of that control for all bands, facilitating quick global adjustments. The highly-resolved ratio control permits fine-tuned adjustment from 1:1 to 30:1, providing effects ranging from subtle compression to hard limiting. Linkable faders adjust input and output gain for left and right channels in stereo mode, and mid and side channels in mid/side mode. Accompanying each fader set are high-resolution, multi-colored ladder meters and fader and level readouts.

Stereo Imaging
The Stereo Imaging module adjusts the width of your mix, corrects L/R channel imbalances and checks mono compatibility. The continuously variable Stereo Width control adjusts the relative balance of mid and side channels and includes a level readout in dB to help guide your hand. Other continuously variable controls--each featuring an attendant readout--adjust the pan position of the left and right channels and provide a Mono Filter for the entire mix. The Mono Filter collapses to mono all frequencies below a high-pass filter's cut-off, producing a more focused bottom end. Tap separate buttons to flip the left and right channels' positions in the soundstage, alternately monitor in mono and stereo, and independently invert the phase of the left or right channel. A Lissajous Vectorscope displays inter-channel correlation in an easy-to-read format that helps you assess stereo width and mono compatibility. Linkable faders--accompanied by high-resolution, multi-colored ladder meters--adjust output gain independently for left and right channels; linking the faders allows simultaneous adjustment while maintaining offsets. Readouts are provided for L/R fader settings and channel output levels.


The Reverb module offers flattering room, hall and plate algorithms to sweeten overly dry mixes. Each algorithm provides continuously variable controls for independently adjusting Pre-Delay, Decay Time, Early Reflections and Room Size. Draggable nodes on a graphic display adjust the corner frequencies for high- and low-pass filters that affect only the reverb, preserving the dry sound's full bandwidth. Reverb can be applied in different amounts to the left and right channels in stereo mode, and to the mid and side channels in mid-side mode. Separate faders adjust the output levels of Dry and Wet (reverb) audio and include associated percentage-based readouts. Tap on the Solo Wet button to hear only the reverb portion of the module's output.


The Maximizer module should always be placed last in the signal chain. (Each module can be dragged and dropped to change their order in the chain.) The Maximizer limits peaks and raises the average level of your mix, thereby increasing loudness. Comprehensive dither and noise-shaping options are also provided in this module. The Maximizer can operate in either stereo or mid-side mode and provides a separate, linkable input fader for each channel (left and right faders in stereo mode, and mid and side in mid-side mode); multi-colored ladder meters and fader and level readouts accompany the faders. Threshold and Release sliders tailor the limiter's action, while the Margin slider adjusts the master's ceiling, or maximum peak level. Multi-colored ladder meters in the Threshold and Margin faders' slots help guide your adjustments, and an Attenuation meter and associated readout display the amount of gain reduction applied to your master. The Maximizer module also lets you choose rectangular or triangular dither (or no dither) and any of three types of noise-shaping (or no noise-shaping). The dither amount (1 or 2 bits) and bit depth (8, 12, 16, 20 or 24 bits) are also each selected with one tap.

Master Section and Utilities
All the modules, with the exception of the Stereo Imager and Maximizer, can have their left, right, mid or side channel soloed or bypassed, and either mode's two channels can be linked. Four high-resolution faders for left- and right-channel inputs and outputs are accompanied by multi-colored ladder meters, fader and level readouts, and clip indicators. The faders can be linked, maintaining any offsets you created beforehand. Global and module-based presets, transport controls, a waveform overview, Undo and Redo functions, and Import and Export facilities complete the mix.

So how do you monitor - over an iPad quality headphone socket?

If so - what's the point??

Looks amazing - please release for a proper mastering platform (i.e. a computer)

You need an Audio Interface to really make things happen.

And for your information, the iPad is a tool capable of making class 'A' recordings.

Looks like a great little app if they do what they say it does. Nice lot of features for the money. I think I'll wait for a few reviews to come in before I take the plunge.

For now I'll stick to my Ozone 5. That was a joke, BTW before anyone slams me for comparing Ozone to an iPad app.

I can't imagine that mastering on an iPad sized screen isn't akin to performing surgery with motorbike gloves on, possible but unnecessarily more difficult.

Agreed, for now it's a toy. But these guys have a jump on the next generation GUIs. Somewhere, sometime the touch interface is going to get more tactile friendly (providing feedback) and precise (higher resolution, recognizing minute changes). Performance wise, the mobile processors are making really fast strides, they will be desktop powerful soon enough.

gg: this is a mastering app, not a recording one. Do ye have ANY idea what mastering is - any clue at all??

could you possibly go and read a book by Bob Katz - and learn some of the basics of Mastering - that's "Mastering" - before you come on here with your snotty attitude (which reveals your utter ignorance of all "mastering" - that's "mastering" issues)

Decided to spring for Final touch last night - very impressive. It's highly intuitive, has a excellent graphical interface, and it comes with loads of presets and a demo wav file to get you started in the mastering arts. I normally use Sound Forge on my computer for mastering and many of the same tools can be found in Final Touch, but the FT interface is well designed and more fun to use IMHO. If you're one of the growing number of iPad-based music producers then Final Touch will come as a welcome addition to your studio.

@ Synth_Fan, your statements reflect the most noobish conception of mastering I've read.

Regardless, the iPad's onboard AD DA is sub par for pro audio applications. It's a good thing that silicon vendors like Apogee, Focusrite, RME, etc. now make proper interfaces for the platform. The most common application I see of the iPad in professional settings right now is remote control of digital mixing consoles, sheet music/lyrics/setlists mounted on mic stands. YMMV

Flitersweeo... there is a growing body of synth-based music producers that are using the iPad for total music production. The tracks stay in the device until they are exported using Dropbox or Audio Cloud. Of course iPad users are using outboard audio processors for AD DA (same as any computer). The very fact that mastering tools like Final Touch are becoming available for IOS7 just confirms that the iPad is being used for more than displaying sheet music.

Actually we port over to iPad because we can release simplified versions of the originals quickly and make plenty of cash off them.

Wow! So I can buy this and start charging people to master their songs? All I have are some regular earbuds for listening is this good enough? Guess I could use different sets of earphones?

You old farts are just jealous. My iPad is a full on studio that costs a fraction of what you invested and does the same thing 8P

The iPad is not a magic box... you still need a good audio interface and studio monitors if you want professional results, just as you would need for any other computer in order to do mastering. Earbuds won't cut it. I wouldn't trust reference headphones alone to do the job either, but combined with a good audio interface I think you could reasonably get by with headphones and an interface for your iPad and Final Touch.

I just wonder, Why put so much work on a track that 95% gone listening on crapy earbuds or laptop you can connect HiEnd headphones to iPad and get a wonderful sound, good enough for the young people off today. And this app release me from my studio so I can work outside in the good weather or on a trip. Nice job Guys with this app, I gone try it, only problem I live in Thailand and the stupid bank dont let me use my card outside Looking for a solution
