SoundScope VR for iOS is a full-featured audio spectrum analyzer. It provides advanced audio analysis using the latest FFT-based high-resolution algorithms and tools for detailed and precise audio analysis. SoundScope VR allows you to overlay the audio analysis data over a real-time view of your surroundings, to capture what is causing the sound that you are analyzing. This analysis can be saved as a video on your device. If you need a two-channel FFT for your iOS device, check out Transfer Function, a module in our AudioTools app. SoundScope is based on our proprietary algorithms, techniques, and features. Now, you can have the sophisticated analysis of SoundScope VR on the iPhone platform. The single-channel audio analyzer includes these features: RTA Bar graph, RTA Line graph, RTA Bar & FFT graph, Spectrograph, and VR analysis of environmental sound. A variety of smoothing and averaging algorithms are available, including log, lin, Octave, 1/3rd, 1/6th, 1/12th, 1/24th and 1/48th Octave modes. The decay modes include None, 1, 2, 4, 8, and 16 averages, and exponential 1-10 second custom decay settings, as well as Infinite, Fast, and Slow. The frequency scale can be zoomed down to a single octave, and the dB scale can be zoomed down to 1dB resolution. Double-tap the screen to return to full frequency response, and to auto-scale the dB scale. Real-time Spectrograph history is saved, just swipe to see sound events that have scrolled off the screen. Other features include high-contrast mode, variable Spectrograph speed, vertical or horizontal running Spectrograph, Difference mode, Peak Tracking, and FFT Windowing. New features include the ability to replace the background with a live video camera feed, and also do screen recording to capture a record the sound levels and also what is happening physically in the space. This is next-level VR audio analysis. All of the standard AudioTools features, such as Save / Recall and the Generator Panel are available. All settings are automatically saved and restored the next time that you run the app. On iPad and larger iPhones, split graph mode is available, so that you can put any two graphs on the screen at the same time. Check out the screenshots to see if your device supports them. SoundScope RTA Spectrum works great with the built-in iOS device microphone, as we have proprietary microphone compensation and calibration database derived for every iOS device. To upgrade to full professional results, use our iTestMic, or iAudioInterface2 with any test & measurement microphone. Also see our other great audio test and measurement apps including AudioTools.

KORG cortosia, the tuner app that makes it enjoyable to practice the basics Learn “good sound” and enjoy “good performance”! *This app can evaluate only flute, clarinet, trumpet, violin, cello, saxophone, trombone and euphonium performances. (Operating Requirements) iOS8 or later iPhone 5 or later, iPod Touch 5th Generation or later KORG has answered the question: “Can a tuner recognize good sound?” With the KORG cortosia you'll see what's missing from “good sound” with just a glance. Even practice that's slightly boring (such as practicing the production of single notes) will become enjoyable. The cortosia is a completely new type of interactive tuner app designed to improve the overall quality of sound produced by the artist. * Analyzes five elements of “good sound” and rates them in real time * Automatically records “good sound” so you can check your daily improvement in technique * Lets you compete against the world in “good sound” and vie for ranking * Supports flute, clarinet, trumpet, violin, cello, saxophone, trombone and euphonium Analyze five elements of “good sound” and rate them in real time: Just what is “good sound”? Beautiful sound, pleasant sound, sound that resonates in the listener's heart. Perceptions of “good sound” differ between people, but could there be some commonalities? Through cooperative research with Pompeu Fabra University in Barcelona, Spain, under the direction of Professor Xavier Serra, Korg has arrived at a technology “Artistry” (*1) for evaluating “good sound” based on five elements. 1: Pitch Stability 2: Dynamic Stability 3: Timbre Stability 4: Timbre Richness 5: Attack Clarity Simultaneously with the tuner display, a radar chart shows the results of analyzing these five elements in real time, and scores them on a scale of 100 points. While tuning, you can see at a glance what aspects of your tone are lacking. You can also listen to a model tone and hear how it differs from your own sound. This is highly recommended for beginners who have just started a musical instrument, as well as for intermediate players who want to advance to the next level. *1: Automatic Rating Technology for musical InSTRument plaYers Automatically record “good sound,” and check your daily advances in technique: Data is automatically recorded and kept when tuning and scoring. You can audition the accumulated recording data or recall a radar chart for it, and you can also check the number of hours you practiced and your best score for each day. By looking at your past results, you can see how you are progressing. In addition, you can post your score to a social networking service such as Facebook or Twitter allowing you to record or upload your daily progress (or backsliding) as if you were writing a diary. Whether you use this to compete with your friends or to give encouraging comments, it's a great way to improve your skill while enjoyably sharing information. Compete with the world for “good sound”: Your ranking is compiled by averaging your highest score for each note, and displayed. You'll be able to see your current position among performers around the world who use cortosia. Supports flute, clarinet, trumpet, violin, cello, saxophone, trombone and euphonium. A full range of basic functionality including tuner, metronome, and level meter: In addition to a chromatic tuner that benefits from Korg's forty years of know-how in tuner development, there's a metronome that supports tap tempo, and even a level meter, making cortosia a great partner for performance or practice.
