Why Your Audio Sound Like a Robot

Many factors contribute to your audio to sound like a robotic voice. Let us look at the reasons for robotic voice and good practices to know how to enhance audio quality.

1. Echo and Communication issues: The robotic voice can sometimes be introduced in the recording setup rather than in audio processing. If any of the instruments introduce echo or distortion, it will degrade the audio quality. 

2. Audio Processing and Mic Technique:

Similarly, the metallic voice or robotic tint can also result from some audio processing. 

  • Overprocessing: If you are overusing audio effects like compression, normalization, or Audacity noise gate, they can strip away the natural dynamics of the audio and make it sound unnatural.
  • Low Input Volume: If you are someone with a low voice and use effects to boot voice in post-processing, it will exaggerate noise and add the robotic tint. Also, learn how to remove vocals from a song in Audacity, if the voice is low.

Remove Robot Voice in Audacity Step-by-Step

Now, if your audio is affected by robotic or metallic tint, you can use the open-source program Audacity to correct it and make it sound natural. Let us know about the effects we will be using to remove the robot voice in detail.

  • Noise Gate: It is impossible to avoid unwanted noises even with studio-level equipment. While processing, we must remove those voices using noise reduction in Audacity
  • EQ (Filter Curve EQ): Equalization allows us to manipulate sounds of various frequencies.  You can increase volumes of some frequencies and reduce others. You can use EQ for click removal Audacity.
  • Clip Fix: Audio clipping happens when a signal exceeds the maximum limits of the recording, seen as flattened tracks in DAWs. Audio clipping introduces distortion and harsh and unpleasant sounds. 

Let us dive right into how to use these effects to remove robotic voice in Audacity:

Step 1. Open the Audio file in Audacity.

Step 2. At first, we use the "Noise Gate" to derive a "Noise Profile" and remove the unwanted noises in the audio. 

Select a part of the noise with no actual audio (external noise), and navigate to "Effects" > "Noise Removal and Repair" > "Noise Reduction." 

Open the Noise Reduction Effect.

Click on "Get Noise Profile" to generate a noise profile for the audio. This effect also helps you to know how to remove breathing from audio in Audacity.

Get Noise Profile

Now, press "Ctrl + A" to select the complete audio. Again, go to the "Effects" > "Noise Removal and Repair" > "Noise Reduction" settings.

Noise Reduction

Adjust the Noise Reduction, Sensitivity, and frequency sliders to control the amount of noise reduction. Click on "Preview" to check the audio, and "OK" if you are satisfied.

Step 3. Now, we will use the "Clip Fix" effects to adjust the audio clipping and restore the audio in a natural way.

Come back to the landing page, go to "View" > "Show Clipping (on/off)" and see the clipping. You will find the audio clippings in red.

Now, Navigate to "Effect" > "Noise Removal and Repair" > "Clip Fix" and open it.

Open the Clip Fix effect in Audacity

Clip Fix offers two values to apply to the audio:

  • Threshold clipping (%): This parameter allows you to set a threshold percentage considering the maximum level above which the audio is considered clipping. The recommended value is 95%.
  • Reduce amplitude to allow for restored peaks (dB): This allows you to create headroom for repairs while reducing the Amplitude of the selected region. The default value is -9 dB.

Configure the Clip Fix settings

Step 4. Let's work with various sounds to go up or down the frequencies. You can do this with "Filter curve EQ." Try turning down the sounds to remove vocals if Audacity vocal remover not working.

Select the audio, and "Effects" > "EQ and Filters" > "Filter Curve EQ." Here, you will see a graph with frequencies on the X-axis and Sound on the Y-axis. 

Filter Curve EQ

To apply things automatically, click on "Presets & Settings" and select the options. For manual, just tap on the desired frequency and use the trackpad or mouse to change the sound.

Apply the Equalization filter

Step 5. After completing the process, check the audio to see if the robotic tint is gone. Now, to export the audio, click on "File" > "Export" to see the available download options.
