How to Improve Recording Using Audacity – FIFINE ACCESSORIES

How to Improve Recording Using Audacity

If you are just a starter on the audio field, who doesn’t have huge budget for an expensive but still need decent sound quality, after a bit of post-production, the result will the optimum. We will use Audacity as illustration. Different programs are going to be slightly different with the features that they have.

 

Noise is always the issue for every microphones, not just the cheap one. So it’s essential to make the track as clear and as it can be.

Noise Reduction in Audacity

  1. Select the area that only has the noise.
  2. Go into “Effect”, then “Noise Removal”and click “Get Noise Profile”.
  3. Go back and highlight entire track. And get to “Noise Removal”
  4. In “Noise Reduction”Find the happy medium like 22. And leave the other effect where they are (sensitivity: -0.16, frequency smoothing: 550, attack/decay time: 0.04).

Even you get rid of background noise and the sound is pretty good now, but we still can’t call it a optimum track. Because without change of volume in different frequency, your voice is still a bit muddy. Especially when there are instruments and other vocals pile on top of each other and compete for the same frequency. So the poor sound quality is not often the issue of the microphone itself. What you can do is to lower or boost volume of some frequency to highlight the instrument or vocal, so the whole track can be heard clearer.

You would like to increase volume of high end (over 1 KHz) to add clarity to vocal. Too much bass (20-100 HZ) would make the sound hear like echo, so you would not like to boost it too much. Because we have the melody in the background. So actually sometimes especially in sing, you probably get rid of it. If you also have the guitar sound in the track, increase the mid-range frequency (100-1000 Hz) and for the drum kicking, you would like to boost the low frequency, like say 150 Hz. Though of course, when you are doing broadcast, a bit more bass should help your voice sound good.

It may take you a little while to know exactly what slider to move to get the exact effect you want. This is a bit of trial and error.

Equalization in Audacity

For Broadcast

  1. Select entire track.
  2. Go into “Effect”, then “Equalization”.
  3. Boost to around 6dB at 20 Hz. Lower to below 0 dB at 100 Hz. Then increase volume a little bit to 2dB at the mid-range, like 500 Hz. Boost high end at about 5 KHz to 3 dB.
1-3

 

For Singing

  1. Select entire track.
  2. Go into “Effect”, then “Equalization”.
  3. Click Graphic. Lower the bass like 20 and 40 Hz to around -17 dB. Bring the mid-range (100-1000 Hz) to normal 0 dB, like 500 Hz. Boost high end at about 4 KHz to 9 dB, 5 KHz to 12 dB and 6 KHz to 8 dB.

You don’t always notice that you’re using a low voice certain time and other times a loud voice. Then you will want to use compression to normalize your sound. It’s of crucial importance when you’re podcasting.

Compressor in Audacity

  1. Select entire track.
  2. Go into “Effect”, then “Compressor”.
  3. Drag the “Threshold”to around -30 dB, and “Noise Floor” to about -65 dB.
3-3

 

If you still think the sound is a bit loud (particularly when you’re using Fifine K668 or K053), you will want to give it a negative value, which will turn the whole track down. Then we will have everything in approximate equal wave form.

Amplify in Audacity

  1. Select entire track.
  2. Go into “Effect”, then “Amplify”.
  3. Drag the bar to below 0 dB.
