    Hi guys,

    i'm pretty new to dsp, i would like to implement FIR lowpass filter to a recorded audio clip using codecomposer studio on c5545 booster pack. Can someone provide me a step by step guide to build the project? I've C code for it.
    http://www.ti.com/tool/BOOST5545ULP

    I'm giving analog input through line in, is there a function or c code to obtain the input data samples to use it in my fir function? I would like to run the code on ccs and hear the output from headphone output.

    Thanks in advance

    I've never gone past that point. I probably know about the math part just as much as you: just punch samples into the equation and get the output. I can't help on on what, to me, would be the hardest part which is getting the samples in...that's probably just playing it back somehow and sampling it with an ADC.
