Hi everyone. Been lurking here for a day or two. Unfortunately I've been stuck for a while on something. I'm hoping I can describe it (maybe post an example if needed) and get some feedback on what's going on. For some background, I've read tons of singing/vocal information online so feel free to use any terminology.
My problem seems to center around vowels and the first formant/chest voice. The reason I believe this is because when I record myself singing vowels, the waveform more often than not has higher peaks than it does low valleys. In other words, the ratio favors the high part of the wave.
I've tried everything from singing forward, back, head, vowel modification, tongue placement, larynx position, lip formation, velopharyngeal port closure, etc. and nothing seems to consistently get the waveform to be even.
I've also noticed that when I record professional singers the waveform is typically balanced.
What might I be doing incorrectly that would cause this distortion of tone? I'm all out of ideas! Thanks in advance for any advice anyone has.
P.s. As it may have some bearing, I am a 28 year old male.
