This is the simple implementation of flac compressor. You can find information about it here. Also you can find code of flac here.

Compile program

    cmake -S . -B "path to folder to build files"
    cmake --build "path to folder to build files"

Compress file

    ./demo-flac input_file

Decompress file

    ./demo-flac -d input_file

Flags

Change bps of input file (by default it is 16 bit)

    --bps=x

Custom output file (by default it is input_file.dflac)

    -o output_file

Change number of channels (by default it is 1)

    --channels=x

Change sample rate (by default it is 44100)

    --sample-rate=x

Change block size (by default it is 4096)

    --blocksize=x

Make int signed or unsigned (by default it is signed)

    --sign=true
    --sign=false

Decompress flag

    -d

Make exhaustive search for fixed subframes

    -e

What differences does flac have

• Type of input files. In flac you can use different types of input files but here you can use only input files that have raw data.
• In flac there is 4 types of subframes (constant, verbatium, fixed and lpc). Here you can find only 3 types (constant, verbatium and fixed).
