Waveform

[Baltimoregator]

Hi, I am new to this forum so pardon me if this is over explained.
I recorded some audio that seems to change each time I play it. Is there a type of wave that can be manipulated by another wave to sound different each time you play it? I noticed the waves have very large crests both (+) and (`-) db. I also noticed the actual baseline of the wave moves across the DC frequently. Im not sure if I am explaining this correctly so I attached a couple samples.

Sound exactly the same every time to me…

Not really, but if you play other audio at the same time, it will interfere and the sum may sound different than the parts.

I looked at Sample 1.wav - it has a lot of really low frequency content, subsonic even (below 20hz). This can do funny things to our speakers or headphones, so depending on what you're playing it back on, you may hear strange things.


Try adding a strong/steep high pass filter at (say) 25 or 30hz and see if that helps.
