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.

Select two files or paste two texts and compare them. Select two directories and compare them to see which files have been added, removed or modified, and selectively reset modified files to match the original ones. If files have slightly different names, you can match them by alphabetical order or a custom name map, and selectively rename them afterwards so that the names are equal. Export patches from two compared text files, or apply saved patches to an existing file. Create edit scripts that are applied non-destructively to a text file and export the resulting text.
