Store description excerpt
ToneScope helps you see and understand sound in real time. ToneScope transforms complex audio into visual representations that are easy to interpret. Whether you're exploring music, investigating environmental noise, or simply curious about the sounds around you, ToneScope makes sound easier to understand. It uses a multirate FFT approach to achieve high frequency resolution at low frequencies while remaining efficient for real-time use on iOS. Users can analyze audio in real time or record sound locally and analyze it later. All processing is performed entirely on-device. Optional audio recordings are saved locally under user control. No data is transmitted, uploaded, or collected. Designed and developed by Newton Niu.
