So I've been asking a lot recently about potential reasons why my channel only has 145 subscribers after 4 years, and audio is the only thing that came up.
Does anyone maybe know what to do with these audio issues in my last few videos? The background noise primarily. Any ideas on how to fix this in OBS?
Hmm yeah, I can hear an intereference / high-pitched sort of whistling sound, particularly in the left channel.
The best way to improve audio quality is AT SOURCE - ie prevention is better than cure. Once bad audio is recorded, all post-production techniques to get rid of it will also reduce the quality of the "good audio"
The most common causes of this are a bad quality microphone, bad cables to microphone, wrong settings on microphone, electrical / noisy equipment close to microphone that are causing electrical interference. Then, there are some post-production processes you can do to reduce ambient (background) noise. Audacity's "noise reduction" option is very good at this.
Please describe your recording setup (hardware, mic you use? Mic settings? How is your mic physically installed? Is it close to electrical devices? Audio recording software you use? Software settings? Post-production process you do?)
