about wavelet decompostion of CWs?

Started by wang...@163.com April 25, 2006
Dear all,
I want to use wavelet analysis to decompose and reconstruct CWs based on biorthogonal FIR linear phase filter banks , but I have found that the time delay of 3-level wavelet decomposition of CWs is very high (about 6 speech frames). Can you tell me how to solve the delay problem?
Does the wavelet method benefit to quantization and bits compression?

Thank you!
