When I try to use a mixer to put two buffers together and send that to output, the result is garbled and static-y. Any idea what's causing this? Patrick Vlaskovits October 17, 2017 20:14 Follow Some of the buffers you point to contains memory garbage. Related articles Does the Superpowered mixer allow to process any number of inputs (not only 4)? I used the functions createWAV, fwrite and closeWAV, and they could to save files in app data directory but not in the sdcard. Why is that? Is there anyway to use the other microphone instead of the previous one ? We want to save files into WAV. What is the best method for that? Is it possible to have the SuperpoweredFrequencyDomain obj apply a windowing function (Hamming for example) on time-domain data before doing the FFT?
