Did you record the audio coming from the microphone or something else?

    The hissing comes from the microphone, more precisely, it's a noise of your phone's audio hardware. – Gabor Szanto May 18 '18 at 08:01
  • understood, but does superpowered Recorder Bypass any audio processing stuff of Android Media Framework? – Vaishali G Bijani May 18 '18 at 18:46
  • I guess you use the SuperpoweredRecorder with SuperpoweredAndroidAudioIO. In this case you are talking to Android's audio stack on the lowest possible level in user space. – Gabor Szanto May 19 '18 at 10:01
  • yes sir, ultimate SuperpoweredRecorder will use audio stack of Android only, so does it bypass any processing before passing recorded buffer to user space? – Vaishali G Bijani May 19 '18 at 16:32

    System-space processing can not be bypassed from user space. Whatever your phone is doing in system space with the microphone input, it will still do it. – Gabor Szanto May 20 '18 at 06:50
  • Understood. so, what is magic behind low latency of Superpowered SDK? is it DSP algorithm or that can not be disclosed? – Vaishali G Bijani May 20 '18 at 09:01
