Hal Chamberlin's "Musical Applications of Microprocessors"

Hey there,

I recently acquired a used copy of the book. Although it's outdated, but there are many quick tricks and guides of making music on the microprocessor.

The thing is, the language in the program codes used is in some ASM, and a bit of Fortran and Basic. They can be "ported" to any newer microcontroller programming languages.

I'm reading about the inverse fast fourier transform in that book. I believe that any new dsPICs or higher end microcontrollers could do that quickly nowadays. :smile:

    Thanks for the tip. Although it is outdated, Amazon wants $54.17 and up for them.

    That was The Bible back when I got into computer music in 1984. Unfortunately I didn't make a whole lot of progress. It's still sitting in a box in a storage locker, though, just in case I ever want to delve back into it.

    I guess I'm glad I got my (used) copy three years ago - I only had to pay $27 for a hardcover in pretty good condition.

    I have a copy. He also had it available on CD a few years ago when I contacted him.

    The PASM FFT I wrote will do 1024 point FFT in about 40ms. It varies a bit with different input data so let's say it can do 10 transforms per second. That's keeping up with a sample rate of 10240 samples persecond, good for an audio bandwidth to 5KHz.

    If we were really keen that algorithm could be split over 2 or 4 COGS for higher bandwidth.

    With a bit of tweaking it can of course perform the inverse transform and be used for sound sysnthesis.

    Mind you that is only good for about 10 bits per sample.

    Looks really cool but I won't spend $60 bucks for a copy. I'll keep it on the wish list and look for a deal. Thanks for the topic!

    I've got one. I am an electronic musician. I have a home studio. This text is vital reading for anyone who is interested in home studio recording. It's a fascinating read for a textbook, although the language is rather archaic for today. I wish there was an update. It's an ablosute must, I am surprsed that there is little to none reference material like this one. I would not understand the harmonic content of waveforms if it wasn't for this text. Please tell Hal many thanks for writing this one. :)

    Yes, Mine sits on my book shelve within arm's length to read once and a while. Got it new and have used a lot from the information contained in the book.

    There are several used copies on amazon right now @ ~$13 plus shipping. Just snagged one (last time i saw this thread, the cheapest copy was more than $50)
