I know this is an OLD post but I have trawled through the entire Engineering Zone and it the only one close to what I need to do right now...
To quote an e-mail I sent yesterday...
"I am setting X-Over using the Evaluation Board – I need to implement a Full IIR or FIR Filter to correct for some speaker problems.
There is very little information on the Analog Devices Site – have you any other resources you can point me at please?
Particularly I need to convert a correction curve into coefficients for the DSP to handle – I cannot find a Tools to do this directly – most seem to have been programmed in MATLAB etc which I do not have access to,…"
"I have been using the Standard Filters and Eq’s the problem is that for some drive units I need to do a full inverse Speaker Correction – see attachment.
It is this I am having trouble figuring out how to do…"
I can generate the Data - but somehow I need to get the DSP coefficients calculated from the Inverse Curve and then apply these in SigmaStudio the Target being a ADU1701
Any help gratefully recieved.
