AudioTools from Studio Six Digital is a suite of professional-grade audio and acoustic analysis apps. Included in the price of this app is a great collection of professional tools -- SPL, RTA, FFT, Speaker Polarity Test, Generator, Audio Scope, CLF Viewer, and Recorder, and the framework to add more powerful modules as you need them. Customize AudioTools for your needs by buying any of the additional optional modules, like Smaart Tools I, SPL Graph, or Impulse Response, at any time right from your iOS device. We test every iOS device and calibrate the microphone level and frequency response for the best results. We have the ability to turn off the Apple low frequency filters, and on many devices we can measure up to 120 dB SPL. Add iTestMic, iPrecisionMic, or iAudioInterface2 for a complete professional audio and acoustic test and measurement platform. Actual reviews: “...AudioTools is a “how did I ever live without it” app”. “I think this application is the best I EVER purchased.” “I have used many thousands of dollars of complicated test equipment that doesn’t measure up to this app suite.” ***** Included in the app price ***** * SPL Meter A faithful reproduction of a classic analog SPL meter. Includes A and C weighting, and Fast and Slow ANSI decay modes. All filters meet or exceed ANSI type 1. * RTA A 1/3 and octave band Real Time Analyzer. Includes touch-GUI range control, a cursor, max/min bars, and noise curve overlays. * FFT Detailed acoustic analysis, up to 32876 points. View full detail or smooth to 1/24, 1/6, 1/3 or octave. Includes cursor, scalable graphics, and peak tracking. * Polarity Speaker polarity checker. Route the test signal to a speaker, and read the polarity of the speaker on the screen. * CLF Viewer Show loudspeaker data, including plots for impedance, axial response, sensitivity, polar response, and 6dB coverage, and a 3D color balloon plot. * Delay Finder Measures the time it takes for a pulse to return from a speaker. * Generator Generates sine waves, square waves, white and pink noise. * Line Level Tests A line level measurement function and frequency counter. * Audio Scope A dual-channel audio oscilloscope that includes auto-triggering, variable gain and sweep rate, and storage of scope images. * Recorder A mono/stereo audio recorder with WAV and compressed formats and 8k-48k sample rate. Transfer files via WIFI. * File transfer of results via wifi to PC / Mac. * Audio Calculators ***** Optional modules available for purchase from within AudioTools ***** * SoundScope VR - FFT-based audio analyzer with VR. The powerful acoustical analysis module. Includes RTA graphs to 1/48th octave and Spectrograph, and can display VR. * Transfer Function -- Requires 2-channel interface. Two-channel FFT-based measurement. Allows you to analyze sound system performance with music or pink noise as the signal source. * ETC Energy Time Curve. Plot decay of an impulse over time, and compute RT60 time. Internal or External trigger. * Impulse Response Record and analyze an impulse or sine sweep, compute octave and 1/3 octave ETC, T30, C50, C80, CT, Definition. * LARSA Fast and accurate sine-sweep measurement of loudspeakers and rooms. * SPL Pro Digital SPL meter with ANSI Slow, Fast, Peak, and Impulse mode, along with LEQ. Includes A and C weighting, and all 10 octave band filters. * SPL Graph Plot second-by-second SPL level for up to 24 hours, and optionally record the audio. Also, add the optional Octave Band Logging upgrade to elevate this tool to rival any professional logging SPL Meter. * SPL Traffic Light Monitor live sound levels SPL and Leq and see status in a simple green-yellow-red display. * STIPA Speech Intelligibility Meets the current NFPA code standards for testing evac systems and schools. * Speaker Distortion Measure THD+n of any driver. * THD+n (requires iAudioInterface) * Impedance Meter and Plot (requires iAudioInterface) * Phase Meter * Amplitude Sweep

The Analyzer is a combination of a sound pressure level (SPL) meter and a full range multiple bands frequency analyzer. It is mainly designed for audio professionals who need to evaluate different working environments (e.g. studios, live stages)... that’s why it’s perfect for anyone who’s in need of acoustical analysis!! It is easy to use and comes with amazing features only known from professional acoustic tools. Use the Analyzer for measuring stages, testing speakers, setting up your hi-fi system, evaluating sound mixing environments, analyzing your instrument... or for measuring the noise your neighbor makes with his new stereo! The Analyzer is pre-calibrated for all iDevices, but it includes a calibration function as well. It comes with a highly intuitive user interface with zoom gesture control, individual color settings, reticle zoom and many more exciting features. The Analyzer can store, load and export measurement data and supports iCloud storage. Combine the Analyzer with external microphones such as the MicW i436 or Microtech M372 for better measurement performance! Or use it with external USB audio hardware like the RME Fireface UCX or the Alesis IO dock, change the measurement scale to dB (FS) and use it as a studio Realtime Analyzer! ANALYZER FEATURES SPL Meter: - SPL measurement weighting functions: A B C Z - Industry standard response times: impulse, fast and slow - Meter switchable to dB FS for measuring with external USB interface - Pre-calibrated for all available iOS devices Realtime Audio Analyzer (RTA) audio engine: - Bandwidth selectable from 1 octave up to 1/1200 octave (depending on your iDevice) - FFT block size from 1024 to 65536 samples - 6 different FFT window functions - Leq measurement - Automatic peak detection - Signal generator: pink and white noise, sine - Manual and automatic calibration - Frequency response compensation for different mic characteristics of the built-in microphones RTA graphics: - Touch gesture zoom - Reticle with lens functionality - Bar or FFT line view - User definable graph colors - Create up to 14 snapshots with hold, Leq, or snapshot function - Workspace concept: store all current snapshots and color settings - Snapshot and workspace storage, load and export - iCloud support: move files between local and iCloud storage - Export to .csv oder .png files: share them via Mail, Dropbox, iTunes etc. - Import of .csv files AVAILABLE AS IN-APP PURCHASES: - Frequency response compensations for Mic-W i436 (with individually adjustable sensitivity), i266, i456, i825, i855, iShotgun and the Apple EarPods
