git clone https://github.com/aikiriao/AAD.git
cd AAD
make

Makefile?

Hi @aikiriao .

Maybe separate code and docs?:

mkdir src
mv *.c *.h test src

Makefile:

CC = gcc
CFLAGS = -std=c89 -O3 -g3 -Wall -Wextra -Wpedantic -Wformat=2 -Wstrict-aliasing=2 -Wconversion -Wmissing-prototypes -Wstrict-prototypes -Wold-style-definition
CPPFLAGS = -DNDEBUG
LDFLAGS = -Wall -Wextra -Wpedantic -O3
LDLIBS = -lm

SRCS = src/aad_encoder.c \
       src/aad_decoder.c \
       src/aad_tables.c \
       src/wav.c \
       src/command_line_parser.c \
       src/main.c
OBJS = $(SRCS:%.c=%.o)
TARGETS = aad

all: $(TARGETS) 

rebuild:
	make clean
	make all

clean:
	rm -rf $(TARGETS) $(OBJS)

$(TARGETS) : $(OBJS)
	$(CC) $(LDFLAGS) $^ $(LDLIBS) -o $@

%.o: %.c
	$(CC) $(CFLAGS) $(CPPFLAGS) $(INCLUDE) -c $< -o $@
