- My project is Digital audio copyrights protection
- The task is to embed and extract of audio or image into another audio file
- First have to convert the both audios into Discrete Cosine Transform
- Then original audio have to divide into segments
- Then have to do embedding, in this case comparing the frequencies(Dc coefficients)
of both audio we are going to embed.
- for an example if watermark audio's frequency is something 0.4121 and the original
audio's frequency is 0.4120, then the difference is 0.0001 so we are going to replace
the original frequency as 0.4121 and we will take the position of that frequency save
it separately. then we will convert the original audio using Inverse Discrete Cosine
Transform that will be watermarked audio.
-finally have to do the extraction process that will separate the watermark and audio
Dear Client,
I have master degree in digital signal processing. I have experiences in utilizing DCT in 1D and 2D (image) signal.
What would be the audio format? wav?
