DSP implention/testing/refinement of existing noise reduction algorithm

we need a dsp professional ,long time ,good price (finally)

Hi, we are using a algorithm ,which do noise reduction ,fft,etc ,it's working ok ,however ,it seems the noise reduction not so obivously, it seems to have big background noise.

ok,below are our full requirements :

we are developing hearing aid based on RSL10 ,it has arm coretex m3 mcu and lpdsp32 DSP .we use DSP to do noise reduction ,equalizer,etc

first step is : build a good noise reduction .our DSP is LPDSP32, we have our noise reduction on LPDSP32 ,seems not good enough

we need use LPDSP32 ,if one LPDSP32 not strong enough ,we will have 2 LPDSP32s

Skills: Electronics, Matlab and Mathematica, Engineering, Audio Processing, Machine Learning (ML)

Hello, There are two major sources of noise in hearing aid devices, background noise and internal echo. There are different ways to tackle with each such as beamforming and adaptive filtering (echo canceller). Some of More
