    Hello everyone
    I'm currently on working on my project which is watermarking .wav files using Discrete Haar Wavelet Transform, i'm familliar with either java and vb but i'm really new to the audio part. Can anyone give me some advice where i can get started ?

    First of all i know
    1. First of all if i were not mistaken from .wav file, i need to extract the frequency. so if there any reliable source code to do it, i will really grateful :D
    2. Then i must decompose the frequency with haar transformation which is i still confuse which one of haar transformation should i use, is it the 1-D, 2-D, or multiresolution HAAR transformation.
    3. After the decomposition process i need to embed my watermark, but i don't know how.:confused::confused::confused:

    Can anybody give me some advice, thanks
    Waiting for reply,
