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.

Protecting your personal and confidential information since 2009, Krypton is the first, simplest and most reliable App on the iOS Store to strongly encrypt entire documents and folders. Now also available on the macOS App Store. Your stuff is secure from prying eyes no matter where you are in the world. Metaphorically, Krypton keeps your encrypted items in a special vault, with each item contained in their own deposit box; to gain access to an encrypted item the vault must be open and the passcode key must be used to unlock the deposit box before you can discern the plaintext contents inside. In iOS the vault may be open or closed, while on macOS the vault opens upon Log In. Because the unit of encryption is an entire document or folder, Krypton is not a password manager in the traditional sense, although you can maintain a document of all your passwords that you encrypt between uses. Krypton can encrypt any type of document, including but not limited to: • Pictures and movies from your photo album. • Email messages from your mailbox. • Songs, PDFs, movies, Zip files, word processing documents, text files, images, program source code or any other object that you can download over the network or from your personal web server. • Anything on the iOS pasteboard. • Any document other Apps are willing to Share, such as Pages, Numbers and Keynote. • iCloud Drive and Dropbox files for easy cloud synchronization. Krypton uses strong encryption on each item. This has several ramifications: • If your passcode is strong enough to withstand a brute force attack, no one is going to see your stuff. • If you forget your passcode, no one can recover your stuff for you! But only that one document is lost, not your entire collection of items. • Your stuff is secure even if your iDevice or Mac is stolen, or iCloud Drive or Dropbox account is compromised.
