Guitar-S2S-Engine

Terminal-based Guitar String-to-Spectrum Simulation Engine written in C.

• Module summary

1. Fretboard static const char * const fretboard[6][13] (standard tuning, 0–12 frets). const char *get_note(int string, int fret) – returns note or NULL for invalid input. Input is validated; data is const and immutable.

2. Spectrum int get_color_code(const char *note) maps C‑B to ANSI codes (red, green, …). void print_colored_note(const char *note) prints a note in colour. void animate_note_color(const char *note) clears the screen and cycles through ANSI shades with usleep() delays (wrapped for Windows).

3. Note Engine Converts note name and octave to frequency using A4 = 440 Hz: Recognises sharps and common enharmonic equivalents. Uses twelve‑tone equal temperament formula.

4. Interactive main.c Repeatedly prompts for string (1–6) and fret (0–12); 0 quits. Derives octave from string & fret (open‑string octaves hard‑coded). Displays note name, frequency and an animated coloured output. Uses fgets/sscanf for safe input; handles invalid values gracefully. Cross‑platform handling of usleep() for Windows.

5. Build infrastructure Makefile with gcc flags (-Iinclude -Wall -Wextra -std=c11 -lm). .gitignore excludes object files, executables.
