I am using ''Audio playback and recording'' example which is one of the firmware libraries downloadable from STM32 [login to view URL] board I am using is STM32F4 and I would like to apply a filter and then modulate the out put signal from the recorded voice using this [login to view URL] C code for the filter I am going to use is available and modulation part is only multiplication of the gained output from filtering stage with a sin wave with frequency 250 HZ that I already have [login to view URL] my problem is only implementation of all these elements every thing which is needed is prepared in advance. I am kinda of new in this and I couldn't figure it out how this example exactly work but it shouldn't be hard if you are familiar with embedded systems [login to view URL] programming language which is used for this program is C.

Hello, This seems like a simple enough project (more DSP than embedded). I've worked with ARM based boards extensively before (not the STM32F4, though) and I'm sure I'd be able to help. Feel free to review my profile or PM me for any additional information. Thank you for your consideration. Regards, Nikola
