Hello today I'm going to show you how to improve the quality of your audio
now this is an example using Audacity and i'll put the link in the description to this video
and what i've got here is an audio recording so this was originally on an audio reel
which has been digitized. The audio reel would have been done in 1966 so you're looking at a pretty
old recording this recording was made in a church what i'm trying to do is to remove the recording
hiss which you will typically get in an audio reel or a cassette tape if you remember what those are
okay then so let's get into this and do the Noise Reduction. I've got Audacity open which is
freely available i've imported my audio file and you've got it here so the there are two steps to
Noise Reduction so i'll show you what they are so if you go to the Effect option and Noise Reduction
it's going to ask for a Noise Profile first and what this means is, is to understand what
is the definition of recording hiss so the first thing you have to do is look for
an area of the recording where you think has recording hiss so I'm assuming you can use Audacity.
It's not that difficult, so this bit here looks like a good option let's play it back
if you look up here the noise is between 33 and 30. it goes up with some background noise
but that looks like a good bit of recording so i'm going to Select it.
it doesn't have to be a huge amount. Go back to Effects / Noise Reduction / Get Noise Profile
so the next step is to then apply this noise profile to the recording so you Edit / Select
there are lots of options but for the purposes of keeping this simple i'm going to Select All
go back to Effect / Noise Reduction
and click Okay. So now we've applied the Noise Reduction so we'll go back
to the section that we sampled and remember the noise is between 33 and 30. i'll play it back now
was here and it's kept the background noise
i'll give you a sample of some of the other areas of the recording
that's music
that's some background noise
we have our very beautiful crib here there's priests i mean it's a very old recording and
it's not brilliantly recorded. So there you go, it takes Audacity less than a minute
to do Noise Reduction on 36 minutes of audio so there you have it so i think this is demonstrated
that Audacity is quite simple to use it's free and it's quite quick to process and it can
seriously improve the quality of your audio tapes i would caution you that sometimes the
Noise Reduction can impact noise fidelity so if you found this recording useful i'd be grateful
if you would like share or subscribe and I look forward to speaking to you in the next video
