10月4日的Audio Pitch Tuner应用程序分析

Pitch Tuner is an app that uses your device’s microphone to detect pitch in real time. It displays the detected sound as a note name, frequency (Hz), and cent deviation, and includes a clear meter and indicators that show whether the pitch is flat, in tune, or sharp. The A4 reference pitch can be adjusted from 430 to 450 Hz, and transposition from -11 to +11 semitones is supported. Pitch Tuner is a simple and easy-to-use tuning app for instrument practice, vocal training, and ensemble tuning.
