Query: amateur book writing skills and bad programming skills

Well I was expecting something a little more professional. His knowledge of the DSP world is not in debate, but his communication skills defintely are. This is not really a techincal manual, this is an 'author-having-a-converstation-about-dsp' type book. He just talks about DSP in his own words and throws out over-generalized, under-explained concepts of DSP with slight regard to audio processing, with very few real models or examples.And for you programmers like myself, his code is almost UNREADABLE! His tab formatting is worthy of a true amateur hack. Don't expect to be able to use his code intelligently without a lot of reorganizing.The book does have some redeaming qualities. Some of his explanations do manage to intrigue and delight you. However, overall I'm dissapointed, as this book was marketed more as a Programmer's bible to dsp, but there is nearly no programming examples or ideas even in the book. Just talk...
