Read full description

FFT Spectrum Audio Analyzer transforms your device into a professional-grade audio measurement system. Whether you are calibrating home theater speakers, tuning car audio systems, analyzing room acoustics, or troubleshooting sound equipment, this app delivers the precision and features that audio professionals demand. PROFESSIONAL FFT ANALYSIS Real-time Fast Fourier Transform analysis with multiple resolution options. Choose from 4096, 8192, 16384, or 32768 point FFT sizes to balance frequency resolution and response time for your specific application. Higher FFT sizes reveal fine frequency detail while smaller sizes provide faster updates for dynamic measurements. OCTAVE-NORMALIZED DISPLAY Pink noise appears flat on the display, following the standard convention used in professional acoustics measurement. This octave normalization makes it easy to identify frequency response problems and compare measurements to industry standards. FLEXIBLE SMOOTHING OPTIONS Select the level of detail that matches your needs: - 1 Octave smoothing for quick system overview - 1/3 Octave for standard acoustic measurements - 1/6 Octave for detailed speaker analysis - 1/12 Octave for crossover tuning - 1/24 Octave for precision measurements DECAY AND AVERAGING MODES Multiple visualization modes help you capture the information you need: - Time-based decay (0.5s to 8s) for live sound analysis - Peak Hold to capture maximum levels - Running Average for stable long-term measurements MEASUREMENT TOOLS - Touch cursor for precise frequency and level readout - Peak frequency tracking with automatic detection - Pinch to zoom for detailed frequency range inspection - dB scale adjustment for optimal dynamic range display SAVE AND COMPARE Store measurements for later reference and comparison: - Save unlimited spectrum graphs with timestamps - Recall saved measurements as overlay for A/B comparison - Baseline subtraction mode shows difference from reference - Rename and organize your measurement library EXPORT AND SHARE Document and share your measurements: - Export high-resolution PNG images to Photos - Generate XLSX spreadsheet files with frequency and dB data - Share via email, messaging, or cloud storage CALIBRATION Device-specific microphone calibration ensures measurement accuracy. Adjust the calibration offset to match external reference microphones or compensate for known device characteristics. EXTERNAL MICROPHONE SUPPORT Connect professional USB or Lightning audio interfaces for improved measurement accuracy. The app automatically detects and switches to external input devices. USE CASES Home Theater Setup: Measure and balance speaker levels, identify room modes, verify subwoofer integration, and optimize crossover settings. Car Audio Tuning: Analyze frequency response at the listening position, identify resonances, and tune equalizer settings for optimal sound. Live Sound: Quick system checks, feedback identification, and real-time monitoring during performances. Studio Acoustics: Room analysis, monitor calibration, and acoustic treatment verification. Speaker Testing: Frequency response measurement, driver matching, and crossover design verification. Education: Visualize sound and frequency concepts for teaching acoustics and audio engineering. DESIGNED FOR PROFESSIONALS Clean, dark interface optimized for use in low-light environments. High contrast display with cyan spectrum trace for easy visibility. Responsive controls designed for one-handed operation. No internet connection required. All processing happens locally on your device. Your audio data stays private.

About

Augmatic GRE

Generate complex and evolving drum patterns using algorithmic and Euclidean engines. This app creates MIDI notes that require a separate sound source to produce audio, offering deep control over rhythm and dynamics.

Highlights
  • Algorithmic and Euclidean rhythm generation
  • Morphable Grids Engine for evolving beats
  • Blend control between pattern types
  • Linear drumming for articulate patterns
  • Velocity bender for expressive dynamics
  • Groove tools for swing and timing

MAIN FEATURES: - 6 Algorithmic Channels - Bass drum, snare, hi-hat, plus accents which create complementary rhythms, not duplicates. Each channel can generate its own rhythmic voice for rich, layered drum patterns. - Topographic Engine - Morphable, evolving beats based on the Mutable Instruments Eurorack module. Navigate an X/Y map of interconnected drum patterns extracted from actual drum loops with smooth interpolation between patterns. - Euclidean Engine - generate evenly distributed, world‑inspired rhythm patterns using Euclidean algorithms. Configure steps, hits, and start position independently on each channel for precise control. - Blend Control - Crossfade between Grids and Euclidean patterns to introduce variation while preserving the core character of your groove. - Linear Drumming - Control which drums play together or play alone. Eeach sound has room to breathe. Creates clean, articulate patterns. Used in Hip-Hop, IDM, Funk, Fusion. - Velocity Bender - Shape velocity dynamics for a more expressive, dynamic pulse. Create ghost notes, and rhythmic emphasis that bring patterns to life. - Groove Tools - Swing, humanization, clock division, and timing shift. Fine-tune the feel of your patterns from tight and mechanical to loose and human. IMPORTANT: This app does not produce sound on its own. It generates MIDI notes and requires a drum sampler or synthesizer to play them.

Verdict

The call

The clearest difference is update cadence: Augmatic GRE at every 2 weeks against FFT Spectrum Audio Analyzer's every 4 months. Augmatic GRE also leads on device support (4 vs 2) and iOS requirement (15.0 vs 17.0). FFT Spectrum Audio Analyzer's advantage is price ($6.99 vs $9.99). On ads and in-app purchases there is nothing between them.
