Trinity is an effective integrated mastering solution for digital music production enthusiasts & professionals, containing a set of precisely matched and fine-tuned creative tools for achieving the desired sound and loudness. Focused on a reference-based mastering workflow, Trinity lets you work with an optional reference track whose sound you want to achieve, using a flexible spectrum analyzer to aid in comparing and matching. All controls and sliders are fine-tuned for ease of use, appropriate sensitivity and defaults, making adjustments easy and efficient. Everything is available on a single screen without any distracting menu-diving. 44.1, 48 and 96 kHz sample rates are supported, as well as the following audio file types for import: WAV, MP3, AIFF, MP4, AAC, ALAC (Apple Lossless). Note that very long audio files (> 20 minutes) are not supported. For a detailed guide on how to use Trinity, please visit our website! REFERENCE-BASED MASTERING: - In addition to the raw input audio file, another (professionally produced) track can be loaded as a reference - Easy and immediate switching between both tracks for comparison and adjusting the app's controls to attain the desired sound - Seek bars with waveform previews and one-click seeking - One-click section looping for focusing on a certain part of the track SPECTRUM ANALYSIS: - High-resolution and responsive FFT averaging frequency analyzer - Differential Spectrum feature can show the spectral differences between input and reference track for visual matching - Adjustable response time (averaging) - Precise Full-resolution or Smooth Half Octave Averaged display EQUALIZATION: - Transparent Low-Cut Filter with adjustable cutoff frequency and 12 or 24 dB/octave slope - High-Shelving EQ with either a gentle characteristic or a steeper 12 dB/octave slope and variable gain and frequency for fine-tuning brilliance - Up to three freely adjustable general-purpose peaking EQs - Visualization of overall response curve MULTIBAND DYNAMICS: - Three frequency bands with adjustable crossover frequencies - Two selectable crossover types (custom-designed, smooth Trinity crossover or more surgical phase-corrected 24 dB/oct Linkwitz-Riley (LR4) crossover) - Ratio, Attack, Knee, Release and Gain controls per band - Global "Compress" control and per-band Density control with intelligent make-up gain replace the traditional "Threshold" controls for easier operation - Precise gain reduction meters - The compressor section's response can optionally be included in the spectrum response curve display - Solo toggles to isolate bands for precise tuning NORMALIZATION: - Automatic base normalization of input file - Two realtime normalizers (pre- and post multiband section) with optional analog saturation for transient cleanup, additional loudness maximization or sound shaping MULTIBAND STEREO PROCESSING: - Simple but effective Three-Band Stereo Width (M/S) controls from Mono to Extra-Wide - Fine-tuned with love, individually per band, for keeping perceived loudness and giving useful results - Basic Goniometer (Phase Scope) WAVESHAPER: - Optional Wave Shaping with five selectable algorithms - HQ toggle for High-Quality Oversampling LIMITER / CLIPPER: - Either a look-ahead brickwall limiter or a hard clipper can be used in the final stage depending on taste - Adjustable Attack and Release - Adjustable output ceiling from -2 to 0 dBFS METERING: - Responsive and accurate stereo output meters - RMS or LUFS (Momentary, Short Term, Integrated) metering - PEAK metering always shown simultaneously - Normalizers with accurate saturation / clip indication EXPORT: - Export as 16/24-bit standard or 32-bit float WAV file - Optional rectangular dithering NOTE: Trinity currently does not support running in the background, so your audio will stop as soon as you leave the app or lock the device.

No sound on iOS 26. I unfortunately had to cancel my purchase.

I can’t tell you how much angst and frustration this app has saved me. After months of using on-line mastering and never achieving the results I was looking for this app came to the rescue. It’s given me the confidence to trust my ears and I love it. Worth every penny. Thank you!

Won’t even let me work on audio tracks because it crashed as soon as a load. Wasted money unfortunately

I've never left an app review before and have owned Trinity for less than hour—but wow! It does exactly what you need that other mobile apps don't, and it's immediately easy to use for anyone remotely familiar with music production. Hands down the best mobile mastering app, and leagues better than any of the cloud-based AI mastering services I've tried. It's honestly competitive with Ozone for desktop but way easier to use. Already up to speed, in love, and sad I'm just now discovering.

Attention all musical maestros and tone-deaf troubadours! 🎵🎧 Are you tired of spending more time mastering your tracks than it takes to microwave a burrito? Fear not, for the audio gods have bestowed upon us a miraculous app that'll make your tunes sparkle faster than you can say "auto-tune"! Here's the lowdown on this sonic sorcery: 1. Grab a song that already sounds like it's been kissed by the audio angels. 😇 2. Toss in your raw, unpolished musical gem. 3. Hit a play button and count to 30 (or less if you're feeling impatient). 4. Voila! Your track now sounds like it was produced by a Grammy-winning wizard. It's so easy, even your grandma could do it while knitting a sweater! This app is the audio equivalent of finding a unicorn riding a rainbow – it's that magical and rare. But wait, there's more! We've got a tiny request for the genius developers behind this auditory alchemy: Hey, app wizards! How about tossing in a few pre-mastered tracks as freebies? That way, us mere mortals can start polishing our sonic diamonds right out of the gate. We know you've got some audio gold hidden in your digital vaults – share the wealth, pretty please! 😉 With this app, you'll be churning out chart-toppers faster than you can say "one-hit wonder." So grab it now and turn your bedroom recordings into stadium-worthy anthems! 🎸🚀

You build a track and think, well, this sounds pretty good. Then you bring it into Trinity and suddenly there are a dozen ways to make it sound better! Short learning curve, great manual. Don’t hesitate.

TLDR - Great app - A gem in the app store. I bought this app yesterday and for me, a person who never has had a need to master a track and that also has ADHD and gets distracted/overwhelmed easily, having to leave the DAW and focus on mastering is low-key my favorite feature. In a way it reminds of when I discovered iA Writer - (Lord, 10+ years ago.. wow. Time sure does fly) with the app dedicated to focus on writing, style, prose, with tools to push being better at the craft. All while seemingly at first glance simple but truthfully incredibly intuitive and clearly well designed and throughly thought through (say THAT 7 time fast lol) The reference style approach is clutch. I'm newish to music so I had only heard in passing about referencing and this not only gave me the tools to do that efficiently on iOS, but is pushing me to want to finish tracks I can feel comfortable in releasing. The panel is a nice, subtle touch, but I'm a sucker for skeuomorphism so I could be biased. The incredible detailed manual is very welcome (Is there a PDF I could download that I missed?)

In my opinion, it is the best app for professional mastering... Better than Ik Multimedia and Etc... I have just one suggestion to make the App even better... Implement the possibility of opening Auv3... At least two slots.

This app put some thump in my track that was sorely needed! Five stars for sure. Easy to use and easy to see the difference between the untouched track and the one mastered by this app.
