AcoustiTools® — Professional Tools for iPhone and iPad with Augmented Reality for Live Sound, Studio, Car Audio, and Home Theater. AcoustiTools is a new generation of professional-grade audio analysis and diagnostic tools using ARKit to elevate the audio experience. Five interactive modules – four tile display: 1) Audio Information in Augmented Reality Know the volume level across the venue using the ground-breaking AR Spatial Analyzer module. This module uses augmented reality (AR) to tag locations and calculate the volume level, distance, and delay for each placed tag. Ever need to use asymmetrically placed speakers? Prevent a blurred delay of sound for the audience. With the AR Spatial Analyzer module, you can instantly know how to accommodate for the depth difference and correct the time alignment. - Map The Volume The Volume Variance feature uses tagged locations to quickly map the sound level variations from tagged and labeled main speakers to your current position. The live values display in a 2D overlay allowing you to monitor the sound levels across the audience and keep the volume enjoyable for everyone. - Simplify Delay Timing The Delay Calc feature makes it simple to solve delay problems, calculating the delay timing between a tagged and labeled front speaker and delay stack. The displayed results give you the information needed to quickly sync your audio. 2) Diagnostic PEQ (in-app-purchase) Using the revolutionary real-time Diagnostic PEQ (parametric equalizer) module to listen to pink noise, receive recommended corrective EQ settings to implement for tuning your audio system, whether you’re in a large or small space. Want to reduce the stress of identifying the most problematic frequencies under pressure and choosing the most effective EQ settings to correct it? Available through in-app-purchase, the revolutionary Diagnostic PEQ module diagnoses your audio and recommends a corrective EQ curve to implement for your mix based on live audio or averaged recorded samples. With values for each setting of your PEQ — the center frequency, the Q, and the amplitude — you have a professional, real-time solution to your immediate audio challenges. 3) Diagnostic GEQ (in-app-purchase) If your system uses a graphic equalizer, use the revolutionary real-time Diagnostic GEQ (graphic equalizer) module to listen to pink noise and receive recommended corrective GEQ settings to implement for tuning your audio system, whether you’re in a large or small space. Want to quickly balance your car’s audio system? Set the Diagnostic GEQ to match the number of bands your car’s audio system uses. Available through in-app-purchase, the revolutionary Diagnostic GEQ module diagnoses your audio and recommends a corrective EQ curve based on live audio or averaged recorded samples making it easy to get the most out of your audio system. 4) Real-Time Analyzer The RTA module gives you the information you need to determine the best on-the-fly frequency corrections. The AcoustiTools RTA module includes a red problem frequency line to highlight the frequency on the RTA graph with the largest difference from surrounding frequencies. You can also keep your eye on a specific frequency you set using the blue selectable frequency line. Easily switch between a spectrum color display for bright environments or display the graph in solid blue for dimmer environments. 5) dB Meter - Max-Peak/Max-Average - Fast/Slow - User selectable Max-Average time periods - Threshold Alerts __________ AcoustiTools’ innovative design simultaneously displays four active modules.

ReceptionRating · Positive reviews · Number of ratings

Noise Guru holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Noise Guru has 360 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 100% of AcoustiTools®'s written reviews are positive against 88% of Noise Guru's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

AcoustiTools® ships an update every 2 months, Noise Guru monthly. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
