StringTunerDS is a Nintendo DS homebrew useful to tune guitars and other musical instruments. It can detect a sound’s pitch and display the corresponding tone and octave. It can work in autodetect mode or it’s possible to select a target frequency. When StringTunerDS works in autodetect mode it displays the detected pitch. The target frequency can be setted selecting the target tone and octave or choosing the instruments (guitar or bass), the tuning mode and the string to tune. The base frequency for A can be setted between 435 and 445 Hz (440 Hz at default) and is possible to generate the target sound (this function is not enabled in autodetect mode).

Thanks to for the news.
