Zotify

A .WAV file generator written in C language.

GCC Compile

gcc -Wall main.c err/error.c src/note.c src/read.c src/wav.c src/write.c -std=c99 -O2 -o main

Input format

The first line is the output fileName. The second line contains two floating numbers, bpm and beatPerBar.

The following lines contains the melodies of the song. A song can hold several bar (more bars, of course, result in a larger file), and every bar ends with a single line containing at least five continuous dashes (-----). A bar can holds several melody (up to 10 for each bar). melody is a single line with several note/chord or duration, each can be separated by several spaces. Please refer to the following example:

[Melody 1]
[Melody 2]
[Melody 3]
----- Bar 1 ends
[Melody 1]
[Melody 2]
[Melody 3]
[Melody 4]
----- Bar 2 ends

There's two components in a melody, note/chord and duration.

• note: A legal note is a string with 2 ~ 3 characters. The first 1~2 character is the name of the note, such as C, Bb or F#. The following character is the octo of the note, from 0 to 8. For example, C4, Eb0, D#8 are considered legal notes, while X0, A$2, G9 are not. Besides that, you can use a single character R to represent a rest.
• chord: A legal chord consists of several notes, separated by a single comma (,), and wrapped by round bracket. For example, (G1), (C4,Eb4,G4) are considered legal chords, while [A4], (C#4, C#5, C#6) are not.
• duration: A positive floating number indicating how long the following notes should be played. You should specify a duration before a note, if no duration is specified, the current note will inherit the duration of the previous note.
