If you are new to using Audacity or you are in need of help with some advanced audio recording and editing skills then I recommend you get the Video Guide to Audacity. There are many interesting things to learn in there.
There are many little things that can cause background noises or 'hiss' in your sound recordings. These could be things like bad microphone cables, your guitar pickup, unbalanced lines, analogue tape recordings, or noisy audio components. In order to get a nice clean sounding recording we are going to need to eliminate these unwanted noises and hisses.
Before we can start Audacity best place to buy flagyl online remove hiss and celebrate, I will make a more important point. Try to avoid unwanted background noises in the first place. This sounds very simple, because in most cases it is very simple. Try doing some test recordings of your sound equipment before you start your real recording. You will hear any background hiss or noises you need to remove before you are stuck with it on your final recordings. Below is a little check-list to help you get rid of some background hiss and noise before it happens:
1. Be sure to check your recording levels to ensure you have a nice strong audio signal. If you are not sure how to do this, the Video Guide to Audacity as a great tutorial on that.
2. Get close enough to your microphone so you can get a nice strong signal and reduce any background noise (signal to noise ratio). Here is helpful video on how to improve your vocal recording.
3. Check all your audio cables and gear to make that they are not the source of background hiss and noise. (video on microphone hum)
4. If you have a background noise causing knob or plug on an instrument or amp fix it while you can.
5. Turn off any noisy lights or appliances in your home studio.
Add some of your own ideas to this check-list to help you find and remove unwanted background hiss or noise before it gets on your recordings.
Now, let's get moving on Audacity remove hiss and get ready to celebrate 🙂
The way the Audacity remove hiss function works is Audacity analyzes a small piece of the actual background noises, isolates it, creates a noise profile and removes that noise profile from the recording.
Now let's remove background hiss with Audacity:
Step 1 - Use your SELECTION tool to select a portion of the recording which has ONLY the background hiss or noise in it. In other words as section when you are not playing or singing - only background hiss and noise. If you don't know how to use the selection tool in Audacity the Video Guide to Audacity has a great tutorial on that.
Step 2 - Go to the Audacity EFFECT menu and select NOISE REMOVAL.
Step 3 - Click on GET NOISE PROFILE. Audacity will analyze the background noise in order to remove it.
Step 4 - There are some settings you can play with in the NOISE REMOVAL window. Try using the default settings first and see the results. I suggest you try and play with these settings gently to find what works best for you. There not a 'perfect setting,' so experiment a little and you will get your best results.
Step 5 - Click the OK button.
Audacity will analyze your recording and remove the background hiss and noise based on the noise profile.
THINGS TO THINK ABOUT:
- If you are making a recording and you suspect that you are going to have some background hiss and noise that you will need to remove create a long section of the recording you can use for making your noise profile.
- When you do an Audacity remove hiss and noise function it does degrade the sound slightly. So be ready for that.
- If you are doing multitrack recording try to do Audacity remove hiss function on individual tracks instead of on entire mixes. Some tracks may not need noise removal and you are altering the sound of those audio tracks when you may not need to.
From now on you can open Audacity remove hiss and dance with confidence 🙂 I hope this Audacity tutorial helps you. If you need more help with Audacity please check out the Video Guide to Audacity.
