What do other computer users say about AESTSr64?
| AESTSr64.exe is part of APO Access Service (64-bit) developed by Andrea Electronics Corporation. Ken | |
| Apparently it is a microphone noise filltering process, in other words it does some (probably fourier) transformation on sound input to remove background noise. The name alarmed me as well (what the h*** is Andrea doing with my PC, I didn't invite her). But apparently harmless and needed (further information...) SLF | |
| It's probably useful in certain ways as described by one of the users here however it conflicts with the standard sound output. The reason being is that it may trigger the PC speakers output at random and all haphazardly probably due to detecting a specific frequency range. The program will then attempt to filter that noise or something such as that whilst using headset/earphones which should be activated all the time instead of having this conflict. Because sometimes the sound of the PC speakers can disturb people nearby even though when using earphones for example, so strange bug it is. (further information...) KimKat |
