Removing Hiss

permalink   Sat, Jun 19, 2010 @ 10:53 AM
I am working with a sample that has a lot of hiss noise. I have tried tweaking various settings to reduce it am not completely successful. Any suggestions about how to do a better job at removing it or at least reducing it? I sure appreciate your input. Thanks.

disclaimer: this is a verbatim copy of a topic response I posted on Soundclick for the very same question.

If you’ve got a few seconds of the hiss sound without anything else, try using Audacity’s noise removal tool, which is a multi-band noise gate that “learns” from a sample of the noise you want to remove. Basically, you get a noise profile, and then you can select a sound range and use the “remove noise” tool to lessen the sound in question (including hiss.)

You will want to be very subtle with this tool, as it sounds like crap when used as a hammer. What I mean by that is ease off on the slider control, so that it is three quarters of the way back to “Less.” Used this way you will reduce the hiss to something livable, and not get rid of it. To do more, unfortunately, leaves a lot of odd sounding artifacts in the sound, and deadens the recording.

Used subtly though, it is very powerful, and one of the best free implementations of a tool like this that you can find.

Sometimes it helps to use ‘keep only hiss’ option and get new profile from the result. If necesarry you can get profiles of parts who’ll need other settings

This link helped me with that exact problem in FL studio. If you have similar plugins in the programs you are using, maybe this could help.

Susan, how did you solve you hiss problem?

FL Studio Noise Removal Tool is built on iZotope RX technology.

We use FL Studio noise reduction on occasion and sometime it works
very well.

We are also big fans of iZotope products. Their noised reduction product page is

If you’ve got a little bit of cash to spare, Pinnacle/Steinberg Clean 5 goes quite cheaply on Ebay. I’ve used it a lot for re-mastering 78s, LPs and tapes.

I would thoroughly recommend izotope products , though noise removal is hard to master if you pardon the pun.
