   The audio covers, containing thousands of WAV files, are freely downloaded. Due to the large storage size, we provide 3.6 GB never-compressed WAV audio files here . More never-compressed WAV files will be provided soon. Please cite above papers when you download and test these audio files.

   Due to the large size of WAV files in our experiments, we only provide two sets of small cover audio files, 1000 mono audio covers and 1000 two-channel audio covers , respectively. Accordingly, the audio stego files produced by using steghide algorithm, are provided here: 1000 mono steghide audio steganograms and 1000 two-channel steghide steganograms .

   The audio covers, containing thousands of WAV files, are freely downloaded. Due to the large storage size, we provide 3.6 GB never-compressed WAV audio files here . More never-compressed WAV files will be provided soon. Please cite above papers when you download and test these audio files.

   Another 1000 two-channel audio covers are provided by clcking the following links: set 1 and set 2 .
