Description
SPL (deciBel) Meter featuring RT60, Leq, Sone, Spectrum Analyzer, Spectrogram, Chart Recorder, Signal Generator, Polarity Checker, and Mic calibration.Recommended by "Sound and Vision" magazine. Loved by Audio Engineers worldwide: check out the Reviews! Features: 1/1, 1/3, 1/6 & 1/12 octave RTA modes, Leq (wideband, Octave, variable duration), Sones (Loudness), RT60 (wideband, Octave), Peak Store, Spectrogram, Waterfall, Peak frequency, Impulse, Fast, Medium & Slow filters, Flat & A/C Weighting and film industry X Curve, Averaging, SPL Chart Recorder, Noise Criteria (NC and NR), White/Pink Noise, Sine, Square, Triangle, Sweep, Log Sweep, Warble, Ramp and Impulse signals & loudspeaker polarity checker, L/R select. RTA Store & Load, Hann windows, pinch to zoom, scroll to center.Examples of recent updates (April 2019):v8.0 New Feature: Load one or two stored spectrum files and display both alongside the realtime data.v8.1 New Generator option: swap phase of Right stereo signalv8.2 New Menu option "Set Resolution" allowing to set 4096, 8192, or 16384 sample lengthsv8.3 New 1/12 Octave RTA modeExclusive ISO 1/3 Octave Calibration - can correct for your phones microphone response. Octave calibration discs are moved up or down to obtain a flat response, and match the overall SPL to that of an external meter. Save/Restore of Cal files (popular Dayton Audio iMM-6, MicW i436, also supported).Use: gig measurements, home theater, acoustics, car, etc.AudioTool FFTs sets of microphone samples. Aliasing reduced by Hann windowing. SPL calculated in realtime. Spectra may be saved, then loaded and displayed with the live spectrum. The "Store" button stores the current live spectrum - "Load" shows a list of stored spectra to select.To hide the buttons, tap the screen. To restore them, tap again. To zoom the scale, pinch the screen. To move the scale, drag it up or down (left or right).A pair of cursors can be shown: each can be moved to any position, and will display the SPL & time/frequency values there. The cursors can be turned on and off in the Menu.The loudspeaker polarity checker can be used to check whether a loudspeaker is wired in phase: connect the AudioTool output to the speaker under test, select "Polarity" from the signal generator screen, then return to the RTA screen. If the speaker is out of phase (polarity reversed) AudioTool will show "Pol ---", otherwise "Pol +++" if the speaker is in phase.The Noise Criteria function shows a set of NC contours overlaid on the 1/1 Octave RTA display and the calculated real time current NC value is also shown.The Chart Recorder shows a moving trace of the SPL measurements over the last few minutes.RT60 measurements (how much reverberation or echo there is in a room or hall) can be made using the "RT60" function, triggered using a loud clap (or similar) to or with Pink Noise from the AudioTool generator.The Signal Generator generates White and Pink Noise, Sine, Square, Triangle and Ramp waves, Sine Linear and Log Sweeps, Warbles and Impulses. The generator uses multiple cycled buffers, refreshed randomly so ensuring truly random White and Pink noise. The frequency accuracy of the Signal Generator is typically around 1%. Sine wave fidelity is good throughout most of the audio range. Other signals leading and trailing edges will show ringing and decreasing frequency response artifacts in the upper ranges, depending on the cellphone being used.The above description is a very terse version of the Online Manual, which may be accessed here: https://sites.google.com/site/bofinit/audiotoolThe friendly AudioTool Discussion Group can be used to request features, find/request Calibration files, or report problems.

A great app that makes necessary tuning tools attainable and usable by the regular enthusiast to reach and experience the real potential of prized home and mobile hi-fi rigs.

Good
The analyser works well and is very useful. The signal generator works on my tablet. (Tab 4). Unfortunately the generator does not work on my phone (A 5). The output puttboats.
Great tool for the money. Still have to explore and try more things. Using the Dayton imm-6 whose integration worked flawlessly. Things that are buggy is the signal generator. When trying to change sweep parameters it says invalid number and ignores the input. Maybe a font problem? Also the sweep sounds it has more than one tone.. if you start it more often it sounds if there's a superimposed second tone or harmonic generated. Using a pixel 3a. Keep up the good work!
Something broke and the app is not usable on dark mode on pixel 3xl. I had dark mode enabled for months, so it was working fine before. Not giving a bad rating for now because this a good app.
