What architectural components should a guitar tuning system consist of?

The guitar tuning system typically consists of the following architectural components:

1. User Interface — allows the musician to interact with the system, for example, displaying the current tuning, suggesting tuning options.

2. Sound Analysis Module — receives the audio signal from the guitar, analyzes the pitch of each string.

3. Comparison and Deviation Calculation Module — compares the obtained frequency with the reference frequency for each string and calculates the deviation.

4. Tuning Control Module — provides recommendations or automatically adjusts the string tension (if there is a mechanical drive).

5. Data Storage — saves settings, user profiles, reference frequencies.

6. Integration with External Devices — for example, microphone, sensors, motors for automatic tuning.

Such separation allows for flexible development and maintenance of the system.
