Graphic equalizer - Chris G - Jan 12 9:42:00 2000



Hi All
I am an electronics engineer new to DSP my company has been using
analogue circuits to switch and process audio signals for many years
many of the ic's that we are using are becoming obsolete because
their functions are now being implemented using DSP. My initial task
is to produce a graphic equalizer using a DSP if you can direct me to
a good resource of 'educational' code and or applications information
it would be much appreciated or are there pre-programmed chips out there
for this function
Regards Chris Grant
Development Engineer

Hi Chris,
There is very good book on this topic and some other topics. Check this site: ftp.analog.com/pub/dsp/audio/65L_ezlab.

Hi Chris...

I developed a digital equalizer ( 10 bands stereo with variable fo ,
variable Bw and variable gain) using EZ-KIT Lite from Analog Devices. I´ve
get good results and if you want, I will able to give you the software for
you test the equalizer in EZ-KIT Lite.

Send me an e-mail if you need extra information.

Re: Graphic equalizer - Deep, Brian J. - Feb 11 16:04:00 2000

I would be interested inlooking at your equalizer code as well. I am just
starting out in the DSP world and have started playing with the EZ-KIT.

Thanks,
Brian
