[Vorbis-dev] wavelet transform

Hello,

I am thinking about plugging in Discrete Wavelet Transform as
described in Vorbis I spec:

1.1.2. Classification
Vorbis I is a forward-adaptive monolithic transform CODEC based on the
Modified Discrete Cosine Transform. The codec is structured to allow
addition of a hybrid wavelet filterbank in Vorbis II to offer better
transient response and reproduction using a transform better suited to
localized time events.

Could anybody tell me if it's good or bad idea?
