We currently have C/C++ FFT code with Hann Window function support. For a large data (over 10,000) we want to split this into 1024 samples with 50% overlap. For each 1024 sample, we window and fft.
What is the recommended way to combine all the results from these smaller overlapping results to obtain a presentable results for the over 10,000 data?
Update: For the poor explanation. The process is best illustrated by the following links
