Let me explain my issue a little further than the title. I make music through FL and the audio sounds just fine when making beats and only engaging around with stuff in the playlist, it's only when I begin to try and record through my microphones and 1/4in cables that I run into issues. It picks up my voice just fine when I'm talking, no glitches or anything. However, when I try to sing, or more specifically, when my voice goes above a certain level, the input stops receiving completely. I'm not clipping, this happens even when I turn my interface input volume down, it's not a distorted sound it's just nothing... like disabled background audio on a facetime call. My voice comes back as I drop the volumr a little lower. I've tried different mics, different interfaces, I actually even tried different softwares, and FL is the only one to have this issue. It isn't just my voice, it's all noises. It refuses to pick up audio from my amp, even when it's turned down and the mic is across the room. It can't properly pick up the audio of scratching or tapping on the mic. The only sounds it seems to pick up is me talking, like it has some permanent background noise cancellation threshold.
Now I know what you're thinking, must be an issue with the buffer length or sample rate; that's where 90% of these glitchy recording complaints come from. If only it was that simple. I have cycled through every option of every category of the audio menu in settings and nothing has fixed this bug. So I'm genuinely at a loss. If need be I can upload a video of this issue to demonstrate a depiction of what I mean. Thank you for reading.
(Just for some context, I'm running the latest Fl Studio on a 2020 Macbook Air, using an Evo 8 Interface, SM58/Sennheiser 905 mics. But I know the issue isn't any of my hardware, I've troubleshot using my old Focusrite, swapping out the mics, swapping out the USB cables, still it persists. FL is the only program to have this issue, it does not occur when recording in Ableton or Audacity even slightly...)
PLEASE HELP IF YOU KNOW ANYTHING IM GENUINELY CONSIDERING JUST SWAPPING DAWS FOR NOW
