Tuning a guitar means tightening the string until a specific frequency is emitted. This is the list of frequencies each string should emit to be standard tuned:
The digital process of tuning a guitar will follow these steps:
- Record a live sample of the frequencies captured through the device's microphone.
- Find the most prominent frequency in that sample.
- Calculate what is the closest frequency in the preceding table to detect what string is ...
