This is how you can improve your voice in Audacity
We're going into great detail and now we're making a real improvement using the tools in Audacity. Improving the voice, highlighting it with the equalizer and making it clearer only requires a little know-how.
This tutorial is for anyone who wants the perfect radio voice sound for a podcast, YouTube video, or their own singing.
Because in this Audacity tutorial I will show you step by step how you can edit your voice with the free music program so that it sounds like the one on the radio.
With it you can from a voice recording like this ...
... make a professional sounding vocal like this:
How can you improve your voice in Audacity?
You only have to do five things with your recording - now find out how to remove the noise from your voice and how your voice can sound stronger, nicer and pleasantly loud. Everything for the ultimate radio host sound.
If you follow the delamar power tip at the end, you will become a professional moderator in no time at all. But I'll only tell you at the end.
5 steps to improve your voice in Audacity
Please read through all five steps if you are serious about making your voice stand out and make it clearer. The full beauty of the sound only unfolds if you take all steps one after the other.
# 1 prepare to record
Before we start with the first edits to improve the voice, we need to put the recording in a meaningful starting position.
First of all, we make sure that we have a mono recording. Human voices are recorded with * a * microphone - and that means we only need a mono track (as opposed to stereo with two channels).
Even if you recorded your voice with two microphones or a stereo microphone, I recommend that you convert your recording to mono - this will keep your voice always stable in the middle.
So that the processing, which we are about to do, can be optimally calculated by the effects and we do not get any further sources of interference, we will now normalize the recording to -3 dB.
To do this, we select the entire audio track with a double click, go to Effect at the top and select "Normalize". In the menu of the effect we change the option Normalize peak amplitude and write -3 in the field next to it. Then we press okay.
Now you can already see on your screen how the size of your waveform has changed.
This processing ensures that the recorded audio signal becomes louder evenly. However, it does not change the sound and you will notice that the noise in the recording is also louder.

# 2 Remove background noise with Audacity
If you have little background noise in your recording, a so-called noise gate could help you. You can imagine such a gate like a water dam. If the water exceeds a certain level, the dam lets the water, or in this case our voice, through. Everything below does not come through.
In this way, you can reduce the volume of the background noise or remove it completely during breaks where no one is speaking. Cool right?
The Gate Threshold parameter determines where this threshold should be. So the measure to let through. With a contrast analysis you can very easily find out where to apply this threshold value.
To carry out this analysis, we double-click our entire track again and then go to Analysis and then to Contrast in the top bar.
In the window we see the parameters "Foreground" and "Background". The foreground refers to your voice and the background refers to the background noise. Since we only need to know how loud our background is for the gate, we select a pause in speaking and then go to measure selection.
Now the “Volume” shows what threshold we have to set our gate to in order to remove the background noise. In our sound example, the voice is around -23dB. And now let's check the level of noise.
In our case, the noise floor is -66dB and so we know enough to set the threshold, i.e. the appropriate threshold for our dam.
Now please note: To be on the safe side, we select a value for the threshold for the gate that is well below the level of the voice so that it always comes through.
At the same time, we should also stay well above the level of background noise. In our case, -48dB would be a good choice.
Remove noise in Audacity
If your recording is particularly noisy, Audacity can also help you improve your voice here. For this there is the "noise reduction" effect. It works like this:
First you select a small snippet in your audio file that only contains the noise.
Then you open the noise reduction in your effects.
A window pops up here. In the window you go to "Create noise profile". Then the window closes.
Now you select the entire audio file and go back to the noise reduction effect. Audacity takes your previously created noise profile and filters the noise out of your file.
I would only recommend this effect if your recording is very noisy. If you can make the recording again with less noise, you will always get a better result.
# 3 Make voice clearer in Audacity
We have now created a good basis for our voice and can move on to beautifying the voice. And we will do that with a high-pass filter and a graphic equalizer by raising and lowering frequencies in their volume.
Typically we want a nice bass range as a foundation and a present voice. We will therefore raise low and high frequencies. Most of the energy in the human voice can be found between 100 Hz and 800 Hz. We can call this the body of the voice.
So we can easily cut away all frequencies below 100 Hz. We do this with a high-pass filter and a filter quality of 12 dB per octave. We select the filter again in the Effect menu and then set the frequency and the filter quality.
We mainly use it to remove low-frequency noise or unwanted impact noise. But be careful! If you notice that the filter changes the sound of your voice, you have to lower the cutoff frequency a little. The filter is really only there to remove interference frequencies.
Next we open the graphic EQ under our effects. Here we can make different frequency bands louder or quieter. To give the voice a little warmth, we increase the value by 2-3 dB at 125, 160 and 200 Hertz. Then we press preview to hear what exactly the EQ is doing.
Between 400 and 500 Hz, the voice often seems a bit unclear. To give it more definition, we lower it by approx. 2 dB.
If you find your voice too nasal, you can try the following and lower it by maybe 1-2 dB at 630 and 800 Hz.
To make your voice more present, i.e. to bring it closer to the listener, you can increase it at 2kHz, 2.5kHz and 3.15 kHz. You will immediately notice that the voice comes to the fore, it has more presence and asserts itself better.
Further up in the frequency spectrum we find speech intelligibility. This is mainly determined by the consonants. These are mostly found at around 5 kHz. Depending on which microphone you are using, you can carefully and easily raise a few decibels here. But only if there is a lack of speech intelligibility.
In order to get the hi-fi sound, I would now raise the values from 8 kHz in an arc. My maximum value here is about 7 dB.
So I do the boost at 8, 10, 12.5, 16 and 20 kHz in an arc shape so that we get a little shine in the voice. As sound engineers, we also say that it gives the voice more air. And so our voice sounds much better now.

# 4 Even volume
If your voice is not consistently loud, it will be difficult to hear it on the highway, on the smartphone speaker, or while jogging. That's why we have to make sure that it always remains evenly loud.
The right tool for this is the compressor. This effect reduces the distance between soft and loud passages. So the volume stays the same. For a sound like on the radio, we choose a ratio of 4: 1 - in most cases you are spot on. We are looking for a value between 0.1 and 0.5 seconds for the attack or the response time.
When setting the attack time, you should not select longer than 1 second, otherwise all S, T and sibilants will be overlooked by the compressor. You can set the release or decay time between 1 second and 1.5 seconds.
It gets a little more difficult when setting the threshold value - you will remember, the Noise Gate also has this parameter. Just like there, it is the threshold for our “dam”.
I set the threshold to -16dB. In our case, this is ideal for moving more towards the radio voice.
# 5 The secret to professional productions
With our steps we are already very close to improving the voice in Audacity. The very typical radio sound is created in the end by an effect called a limiter. As a sound engineer, we call this a limiter.
This squeezes the already loud signal a little more and thus takes out even more dynamics. As a result, the voice remains evenly loud. You can find the limiter under the effects in Audacity. We set this to "hard limit", he can grab a lot.
Then we have to make sure that he really has something to do and give him an even louder signal with 4 dB input gain. You have to play with this value to get the right sound. So you can click on preview again and again until you have the radio sound.
If you input a signal that is too soft, the limiter does not have to work and the sound remains almost the same. If you feed in a voice that is too loud, it will be completely squeezed together and lose its melodious sound.
We also tell the limiter how loud the output signal should be. Here you should set a value of -3 dB. Technically, you can also go to 0 dB - but that leads to a poorer sound quality when converting to MP3.
