|eliminate known audio from recorded sound to estimate background sound level via deconvolution|
| by postmortemIA in Operating Systems|
i have 2 signals, one containing audio data which is played on speakers.
second one contains mic data recording the speakers simultaneously.
what ive done so far: align signals in time domain via correlation.
apply fft on overlapping part of both signals and divide one by the other
in order to achieve deconvolution.
what am i doing wrong as the
resulting audiodata is useless.

|Android sound-engine clicks and cuts off the beginning of a played sound|
| by Matt1970 in Software|
This might be a general sound issue, but it concerns my app aswell.
I have noticed, that the Android Sound-Engine (at least on Android

This is hearable as a "click"-sound on activation and deactivation.
The real problem is, that the first s

When setting up a surround sound system you need to make sure you have
adequate speakers connected to your receiver. There are dozens of different
speakers available for receivers, all with varying quality. However, if you
