Audio Quality for OBS
Audio Quality affected by
quality of microphone (microphone with directional sound recording, and wind shield for mic help improve the noise)
quality of audio cable linking between mic and pc also counts (bad quality audio cable may cause spark sound in audio record)
OBS per audio input setting:
there is a “Gear” setting icon next to each input audio source, the one with sound metering panel.
click on the audio gear icon, choose filter. the Filter for mic/aux will show.
play with Noise Suppression and Noise Gate filter, for increase volumn, try Gain filter
normally, it is better to get good mic than software filter the sound.
