1. Digital Audio Processing , EQ question, Spectrum analyzer question
dear newgroup member,
first of all, thank for replying and i really appreciate your
help. recently i plan to built a audio equalizer using one of the
digital signal processor. in order to choose a cost effective
processor , i'm told to calculate the mips consume in my application.
my question is :
General EQ question ?
0) can you please tell me that which type of equalizer (i.e parametric
or graphic equalizer) is more worth to implement ?
0-1) do you know the ISO frequency standard frequency band for the
audio equalizer or the exact ISO number ?
0-2) can you suggest how many frequency band and the center frequency
for each band i should use for my project ?
Question on how much mips require for my application
1) how to calculate the mips need for my application ? what factor do
i need to consider when carry up this process...
Testing equipment/software for EQ
2) since i'm building grahic equalizer, is that any equipment/software
i might require to use for testing my EQ. (in terms of testing
frequency response of EQ) ?
3) can somebody suggest a good site i have a full range of tutorial
regarding how to test the EQ frequency response?
Question Spectrum analyzer for EQ
4) beside building EQ, one other major things involve in my project is
building the spectrum analyzer for this EQ. do anybody know how to
implement it using a digital signal processor and graphical LCD
module? or else can somebody suggest some good website, books,
articles, tutorial or other related topics .
Commercial EQ product question
5) one last question is about the commercial EQ found in the market.
is it most of them are implement using digital signal processor or
made by digital filter IC or even made using anlogue electronics (i.e
using opamp and some rc circuit for some filter cct) ? what is the
normal price for it.
JMAX/MATLAB for EQ simulation Question
6) i'm planning to use some computer software to do simulation. what
i'd in my mind are either using JMAX or matlab to do my simuilation ,
my question is which one is good for those simulation and can somebody
suggest some good site that contain tutorial, sample code.
that'all my questions, i wish you can help me ,thank you.
