App: Trinity | Audio Mastering
Developer: Seven Systems Cross-Platform Media Limited
Genres: Music, Utilities

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.

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. This might change in a future update.

Release notes:
IMPROVEMENTS:

- The project sample rate can now be changed at any time, even with an input file already loaded.

FIXES:

- Fix too short or too long export when project sample rate is changed with loaded input file.
- Fix crash when trying to export with an empty filename.
