Hi all,
Early this month (Sep. 2009) a book on Pd was released in Japan rather silently.
http://www.cqpub.co.jp/hanbai/books/12/12431.htm
As the name "CQ Publications" may tell, the publisher is widely known in Japan for decades for their Ham & Radio related books and magazines.
This book also takes a rather unique approach, introducing Pd as a method to build your own filters and DSP blocks for the sole purpose of expanding your transceiver.
Here is a brief translation of the final chapter on sample patches.
7-1 VU meter 7-2 Analyzing and displaying the input signal 7-3 Morse code generator 7-4 DTMF encoder 7-5 DTMF decoder 7-6 Compressor 7-7 Using the RS232C
The book also comes with a CD-ROM containing Windows binaries of Pd-extended.
