I have been recording sounds like a rubber glove on glass and its going in at -22db. If i turn it up more I get a lot of fuzzy noise. I recorded low then opened it in pro tools. I turned up the volume to make sure it was clean, then I hear that fuzzy noise in everything I have recorded! So the only way I can get it out is with a gate. So my question is do you use a gate in "post recording" or do you record without any noise? I can't seem to get the fuzzy noise out of my recordings during recording. I have my mic trim at 8 out of ten and level set to 5 out of ten. Also do you use a limiter to get a quite sound louder once the sound is all cleaned up?
Shaun, what you're hearing is likely a combination of microphone self-noise and the self-noise of your preamp, as well...a consequence of either not being close enough to the sound, insufficiently sensitive mics, or low-cost preamps. What mic and recorder are you using, and how close are you to the sound source? Usually the answer to such problems are:
- Get closer to the source
- Get a quieter preamp
- Get a quieter mic
...and that's in order of ease and cost, generally. You might be hearing something else, though: What you describe could be anything from traffic noise to RF interference, but if you hear it in all your quiet recordings, the top advice probably still stands.
Details about quiet mics can be found in this thread.
Also, if you are just starting out, you must relativize. Now, I'm not going to be saying that you should not do whatever is worth to get the best sound, I'm going to be saying you have to know your limits.
If you're not in the position of getting any other/new gear and you're stuck with what you have, you will be learning the limits of your equipment as you're using it. It is probably what you are facing just now. I am in the same situation, except that I'm getting to try and buy new equipment.
Yes, the amount of processing (such as gating/BNR) you and me and our fellow on-a-budget beginners have to apply to our sounds does seem to be a lot. At some point you just can't get as close as you'd like to that other pro recording that you know of. As much as you try, your sound does not feel as raw anymore.
I recently was reading The Sounds of Star Wars and it felt great to read that even in such an epic movie (well I'm not a big fan but many people seem to be), the sound effects were not always perfect. Apparently on some sound effect you'd be able to hear somebody closing the fridge door in the above room...
In the end, it's not the sound of your life that you're recording just now. At some point, trying to look for the perfect sounding thing takes you away from achieving your global vision...
To answer your question, I reckon first compress, then expand... your expanding will be more precise and efficient if you're working on compressed dynamics. Again, be aware you might not get the perfect sound, but it's ok for now ;)
While this isn't always possible, another low cost solution is to try performing your sound as loud as possible to help the signal to noise ratio. This can often sound "wrong" as you're performing the sound, but I'm often pleasantly surprised when I play back. If I need to re-perform a sound with more level for s/n reasons, I'll often ditch the headphones as I find I record quieter with them on.
I've used a gate, multiband compression, and iZotope RX Spectral denoise/repair on sounds that I have recorded. Once, I recorded water drops and when i normalized them, or raised the gain there was a lot of mic-self noise, some room tone, and pre-amp noise. iZotope RX did pretty well with removing the noise.
if you're recording it at a lower volume and bringing the volume up later than you're also bringing up the volume of the white noise.
Best off recording at the volume you want it to be relative to how much you're going to increase it in the loudness part of the master..
i mean if your master is going to be 10 db higher than your mixdown then you still want the single audio track to be 10 db lower than that but you don't want to have to increase it by any db in the mixdown before the master because then you're increasing the white noise even more than you have to
I'm having trouble with the xpand plugin in pro tools. seems like no matter what I do.. anything from that plugin at a lower volume is going to sound staticy but If I'm using east west... no problems at all damnit
