Hi, guys
Thanks for your time to read my email first. I’m new about audio, but I have to
make this done:
1. Add a few bytes of data to a sound file and generate a new sound file.
2. If I convert that file to any sound format, these bytes data should still
there.
3. When I play that file anywhere, I pick up the sound with mobile phone
microphone and got these bytes back.
The most important is “Encoding” and “Decoding”, can FFmpeg encode and decode?
Like this paper said: HIDING TEXT IN AUDIO USING MULTIPLE LSB
STEGANOGRAPHY AND PROVIDE SECURITY
USING CRYPTOGRAPHY
Thank you in advance for any help you might be able to provide.
Best Regards,
Mani Wang
