intelli-Morse / Morese Analyze

intelli-Morse is an app for learning Morse communication.
This app consists of 3 tools.
1. Manual keyer
     If you key in correctly, it will be converted to a string.
2. Automatic keyer
     Converts a string to Morse code.
     You can also mute the sound with LED to make optical Morse code.
3. Morse code analysis
     It is for analyzing the sound of Morse code into a character string.
     Advanced analysis can be performed with a special algorithm
The analysis is done using the iPhone's built-in microphone, so no special equipment is required for the analysis.

It was possible to introduce the analysis of a range by FFT into an analysis and to get a high-speed response.
Moreover, in the mechanical morse, the analysis precision is more than 90 % by the highly efficient analysis algorithm.
