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. This breakthrough feature allows you to view information from multiple modules at once and quickly select a module to interact with. Global Features: - Spectral Weightings - Averaging Options - Selectable Block Sizes - Microphone Calibration Trim AcoustiTools — superpowers in your hands.

Vector Calculator is math calculator to find vector addition fast and easy. Vector Calculator give operation of adding two or more vectors together into a vector sum. The parallelogram law gives the rule for vector addition of two or more vectors. Features: • Instant vector calculation. • Add multiple vector by x, y, magnitude or angle. • Vector Image is generated upon calculation. • Save Vector Image into camera roll. • Option to show/hide Grid, Indicator, Label, Vector Label or Magnitude Label for Vector Graph. • Option to enable/disable Background for Vector Graph. • Option to set Background Colour for Vector Graph. A Vector has magnitude [size] and direction. No matter which order you add them, you will get the same result. Magnitude of a Vector: The magnitude of a vector is shown by two vertical bars on either side of the vector |a| Adding Vectors: Vectors can add by adding the x parts and adding the y parts: Example: add the vectors a = (2,3) and b = (4,5) |a+b| = |a| + |b| |a+b| = (2,3) + (4,5) = (2+4,3+5) = (6,8) Common examples of vectors are force and velocity. Both force and velocity are in a particular direction. The magnitude of the vector would indicate the strength of the force or the speed associated with the velocity. Vector Calculator is useful for math teachers, educator, or anyone who want to prepare vector math material for teaching. Also for students who need to learn more detail or understanding of math vector addition operation. Thanks for your support and do visit nitrio.com for more apps for your iOS devices.
