iAudioTool downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Music apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About iAudioTool
Room Reverberation (RT60), SPL (dB) Meter, Spectrum Analyzer, Signal Generator, Polarity Checker.
Features 1/1, 1/3 & 1/6 octave RTA modes, Leq, RT60 (wideband, and Octave), spectrogram, peak frequency, Fast, Medium & Slow filters, Flat & A/C Weighting, Averaging, SPL Chart Recorder, Noise Criteria (NC), White/Pink Noise, Sine, Square, Triangle, Sweep, Ramp and Impulse signals & loudspeaker polarity checker. Frequency spectrum store & load, RT60 store, and Chart store. Stored files can be sent as Email.
Includes ISO Octave Calibration feature - corrects for your device's microphone response. Also includes wideband calibration. The calibration discs are moved up or down so as to obtain a flat response, and match the overall SPL to that of an external meter.
Use: home theater, audio engineer, car audio, etc

AudioTools's Spectrum Analyzer component uses FFT on batches of samples recorded at the microphone. Hann windowing reduces aliasing. Recorded spectra may be stored as files in the device memory, and then loaded later and displayed together with the live spectrum.
The "Store" button will store the current live spectrum. The "Load" button brings up a list of stored spectra. One of these can be chosen, or the "Cancel" item selected to return to the main display, or the "Clear" item selected to remove the currently loaded spectrum.
Data collection can be paused and restarted.
The deciBel meter component uses IIR filters and exponential averaging to calculate Flat, A and C weighted response at speeds of Fast, Medium and Slow.
A pair of cursors can be shown on the RTA and Chart Recorder displays: each can be moved to any position, and will display the SPL & time/frequency values measured there. Initially, both cursors are positioned mid-screen - simply drag them to a new position with the fingertip. 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 (available from the Menu) 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.
Reverberation (RT60) measurements can be made by starting the RT60 component and using a loud clap (or similar) to trigger the measurement. RT60 times measure how much reverberation or echo there is in a room or auditorium.
