Freesound Forums

Hi folks!

I just joined freesounds today, and been downloading some nature-ambiences: rain, birds, crickets, etc...

I'm really sorry for bitching in my second post...
...But I have to say that the audio quality is really bad in many cases.

It's probably because of use of denoiser plugins/programs.

PLEASE BE REALLY CAREFULL WITH DENOISERS!
OR IF YOU DONT KNOW WHAT YOU ARE DOING, DONT USE THEM AT ALL!!!

With these programs you can get this really annoying bubbling sound that is really difficult to get rid of.
In many cases you can hear ot only with headphones, so USE THEM!
I can live with noise, rumble and cracles, but that denoiser sound is really annoying!

Again, I'm really sorry for bitching and shouting at my first day here... and specially before contributing anything myself, but... you know...

Peace,

you're not talking about the previews are you?
because all of those are 64kbps mp3...

Nope, I thought first that that is the case, but problem remains in downloaded files.

I think I know this sound, 'cause I've been also using denoiser plugins.
I get same sound when adjusting threshold too low and trying to get the noiselevel too low...

PS.
I got nothing against denoisers, they have saved me many times.
You just have to bee really carefull when adjusting them, and use cans or keep monitors ridiculously loud...

I think this has been discussed before, but you should always upload very raw sounds, unless for a specific purpose. I would rather download a raw sound and fix it than download a sound that seems good, but is not. That said, not everybody uses "denoisers", so keep looking.

I am very new to recording - just uploaded my first "Hello World" sounds. Although there is quite much noise in the recording, my inner voice told me not to experiment with any filter which I don't know what they do. Seems I was right to leave the recordings that way.

But then I want to know how I can get rid of that 'static' noise in the first place (not recording it at all). I'm using a SONY MD MZ-RH1, set to linear PCM recording, with a SONY ECM CS10.
Does the continuous static noise come from the equipment or is it always present and the ears filter that out naturally?

(As soon as my samples are released, I'll refer to them in case I couldn't describe the noise properly )

I have recorded it in a totally quiet environment, yet there is this constant background noise. Where does it come from?

it's gotta be one of your pieces of equipment, so try to obtain a different mic and a different recording method and see what happens. Other than that there's not much you can do.

turn off the air conditioner... use just enough gain... if it still sounds bad, upload it anyway. I will probably use it.

The ECM CS10 mic has a self-noise of 38dB, according to the Sony website. If you record quiet sounds, this noise will be quite obvious, as you have noticed. Another source of hiss can be the pre-amps on your recorder, especially when turned up high. If you record loud sounds, this "equipment noise" won't be very noticible. You would most likely benefit from a better microphone with less self-noise.

Thank you for your replies; The mic seems to be the main problem (I have no air conditioner ) combined with a perhaps too high record level.
