need help being able to detect hiss
This was rejected for hiss (and other things) but I'm most concerned with the hiss. Is it noticeable throughout or only in some spots?
I can hear more noise in some spots, but I kept looking at the noise floor and it was below -60. So if the noise floor is ok how can I tell there is hiss?
I think this probably happened because I put the gain over 50%. But looking at the recording meter it was below -60 so I thought the "hiss" I was hearing was just in my headphones. The reason I did that was because with the gain at closer to 50%, the wavelengths look so small I worried about the noise floor after normalizing.

Also is there a big difference in the noise floor in that recording and in this one? https://voicebunny.com/projects/1-3A30-promo-video
Hi Leigh,
Thanks for sharing your samples. In the first one (soundcloud one) it is way more evident than in the second one. Could you share with us every element in your recording chain? (mic, recording device etc...) and any processing you're using? Hiss is usually caused by the recording interface but there could be another element that could be causing it.
As you say, hiss is easier to detect in the spaces between words, so you could use a noise gate to lower that noise when you're not speaking. Not necesarily kill it off but just enough so it's below 60db. Currently it's between -55 and -57dB (so not bad at all!).
Keep us posted!

Thank you Seb. I use a CAD Audio condenser mic and a Focusrite Solo 2nd gen into solid state laptop. By processing do you mean after, like noise reduction? I don't think there was any other than normalize.
How would I do a noise gate for when I'm not speaking? Are you saying select all the spots in between words and add the gate there, one by one? (I use audacity.)
