ggwave-from-file

Decode GGWave messages from an input WAV file

Usage: ./bin/ggwave-from-file [-lN] [-d]
    -lN - fixed payload length of size N, N in [1, 64]
    -d  - use Direct Sequence Spread (DSS)

Examples

  • Basic usage with auto-detection of frequency and speed:

    echo "Hello world" | ./bin/ggwave-to-file > example.wav
./bin/ggwave-from-file example.wav

Usage: ./bin/ggwave-from-file audio.wav [-lN] [-d]
    -lN - fixed payload length of size N, N in [1, 64]
    -d  - use Direct Sequence Spread (DSS)

[+] Number of channels: 1
[+] Sample rate: 48000
[+] Bits per sample: 16
[+] Total samples: 69632
[+] Decoding ..

[+] Decoded message with length 11: 'Hello world'

[+] Done

  • Decoding fixed-length payload with DSS enabled:

    echo "Hello world" | ./bin/ggwave-to-file -l16 -d > example.wav
./bin/ggwave-from-file example.wav -l16 -d
