Tools for Audio Steganalysis

Files Description

ID	File	Function
1	batch_scripts	batch scripts for the run of python scripts
2	python_scripts	python scripts for cover and stego audio samples make, QMDCT coefficients matrix extraction, and so on
3	secret_message	secret message files for embedding
4	BatchRename.exe	an executable program for files rename in batch

Procedure of Handcrafted Feature Design

1. Audio samples make.
2. Audio samples check (bitrate, file size, steganographic algorithms, embedding rate).
3. QMDCT coefficients matrix extraction (saved in *.txt format).
4. Train(, validation) and test datasets split (Optional).
5. Feature design and extraction.
6. Steganalysis with traditional classifier (SVM or ensemmble classifier).
7. Record and analyze the experimental results.

Procedure of Deep Network Design

1. Audio samples make.
2. Audio samples check (bitrate, file size, steganographic algorithms, embedding rate).
3. QMDCT coefficients matrix extraction (saved in *.txt format).
4. Train(, validation) and test datasets split (Optional).
5. Steganalysis with deep learning-based method.
6. Record and analyze the experimental results.
