ToneBoosters Morphit is an AUv3 plugin for headphones correction and simulation and removes any unwanted coloration from your headphones! Enable accurate monitoring and calibration, mix with studio reference equalization, and improve the accuracy of your headphones. Used and trusted by thousands of studios worldwide, and now available on your mobile device! The ToneBoosters Morphit app captures the microphone (or external sound card) input and processes the signals in real time. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others. ToneBoosters Morphit will appear in the list of Audio Unit extensions for effect plug-ins. How to use Morphit as AUv3 plugin for headphones correction: 1. Connect your headphones to your iOS device (using the headphones jack, using BlueTooth, or using an adapter as supplied by Apple). You can use any of the many supported headphones listed here: www.toneboosters.com/tb_morphit_v1.html 2. Start your favourite AUv3 host app (Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others) and add TB Morphit as Audio Unit insert effect to a track or output bus. See below on how to use Audio Units in various host apps. 3. Select the headphones you are using from the list of supported headphones provided within the TB Morphit app. That's it - all audio going through the Audio Unit plugin is optimised for your headphones. Key features: - The same professional sound as the acclaimed desktop version - Hundreds of headphones supported! - Unique feature: allow morphing of the amount of correction from 0 to 200% - Unique feature: allow simulation of any of the supported headphones and see how your mix translates - Unique feature: personalize the headphones target curve - Unique feature: use Harman calibration / target curves - Unique feature: data/measurement visualization mode - No external hardware required; works with any of the supported headphones models - Undo/redo, and A/B comparison - Color themes for the user interface - Max screen support in Garageband - Optimised for iPad and compatible with iPhone and iPod Touch See if your headphones are supported: www.toneboosters.com/tb_morhpit_v1.html What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.

Features
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.
