Removing hissing from recording.

[MusicWizard04]

Hi, does anyone know how to remove hissing frequency noise from a recording with an equalizer?

I need help removing hissing noise from a recording of Tom Petty at the SDSU State University on May 30, 2001.

Here's a sample file so you'll know what I am talking about.

EQ is the wrong tool. Get iZotope RX and use spectral denoise.

Find a section of just the noise at least 0.5 seconds long, highlight it, teach it to the tool and tweak the settings so you're only reducing the noise and not damaging the music.

Since its an analog recording, if someone left the tape flips intact, there should be a section somewhere of just the noise. Failing that, there might be a quiet section of the concert where there is no other sound/applause/music to sample from.

Sometimes if a recording needs EQ, it may be best to EQ first, then do the noise reduction. Experiment. Your first results may sounds good today but may sound horrible down the road.

I can't get it. I only have phone and tablet. Would you mind if I sent it to you and could repair it for me?

I can't get Izotope RX10, folks. I only have phone and tablet. Would anyone mind if I sent it to you and could repair it for me?

It's Tom Petty on May 30, 2001.

Before you take anything away, this sounds like a cassette. Do you have the source? It sounds like the azimuth is a little off, and that may solve your problem without de-noising it.


Adjust the azimuth on your deck for each side of the tape, and where the highs sound the clearest, is the ideal place to master.

I don't have a tape deck. I was born in n 2004. What should I do? I also don't have a computer or iZotope. I only have phone and tablet.

Do you have your source? Is it a tape or a digital set of files?

Oh! It's digital set of files. A friend of mine converted lthe first track to mono because channels kept dropping out. I'll send them in a minute.

The amount of hiss is beyond an azimuth adjustment regardless.
A spectral denoise done tastefully will greatly reduce the hiss without damaging the rest of the audio.
