One common challenge users encounter is the presence of background noise in their audio recordings. Background noise can detract from the overall quality of audio projects. Sony Vegas is a renowned and powerful audio editing software and offers various methods to extract clear voice from a noisy audio file.

With features such as lowering the volume and utilizing noise gates, users can diminish background noise and enhance the clarity of their audio recordings. This article mentions the effective ways to remove background noise from audio in Sony Vegas. Here, we'll explore effective ways and practical tips to separate vocals from background noise.

Way 1. Lower the Background Noise Volume

You can employ various methods within Sony Vegas to lower the background noise volume. One straightforward approach is to lower video volume, which can effectively diminish background noise profiles.

Often, background noise exists at lower volume levels, forming a baseline or "floor" within the audio. By reducing the overall volume, the volume of the noise is pushed below this floor. In VEGAS Pro, this can be achieved by sliding the volume slider in the track header to decrease the volume of all audio events within that track. For finer control, the volume of individual events can be lowered by adjusting the Gain level. This method works particularly well when the main voice signal is stronger than any background noise. The background noise persists or if the microphone is close to the source of the unwanted noise.

Follow these steps to lower the overall volume of video in Sony Vegas:

Step 1. Select the track containing the audio clip with the background noise on the Timeline.

Step 2. Locate the volume slider in the track header. Slide it to the left to decrease the volume of all audio events within that track.

Step 3. Click on the specific audio clip in the timeline until you see the Gain level indicator.

Step 4. Click on the top of the audio event to select it.

Step 5. Drag the Gain level down to decrease the volume of that particular event.

Way 2. Use Noise Gate

Noise Gate is another solution for addressing background noise, especially when the noise volume is comparable to the desired audio signal. This feature eliminates any sound below a specified volume threshold. Adjusting the Threshold level slider determines the volume level below which sounds are eliminated. However, the challenge lies in ensuring the desired audio isn't cut off. Fine-tuning the Attack Time and Release Time sliders helps mitigate this issue by adjusting the aggressiveness of the Noise Gate.

Follow these steps to remove background noise in Noise Gate:

Step 1. Right-click on the track containing the audio clip with the background noise.

Step 2. Select "Apply Non-Real-Time Audio Event FX."

Step 3. Select "Track Noise Gate."

Step 4. Click "OK" to apply the selected effects.

Step 5. The Audio Track FX window will open, displaying controls for the selected effects. Click on the Noise Gate effect to access its settings.

Step 6. Adjust the threshold level slider to determine the volume level below which the Noise Gate will activate and reduce the audio volume.

Step 7. Use the Attack and Release sliders. The Attack slider (0-500ms) controls the audio if it drops below the threshold. The release slider (1-5000ms) determines how rapidly it disengages once the volume rises above the threshold.

Step 8. Preview the audio track with the applied Noise Gate effect enabled.

Way 3. Use Equalizer

Utilizing an Equalizer offers a targeted approach to reducing background noise by controlling specific frequencies or ranges of frequencies in the audio. If the background noise is predominantly present at specific frequencies, the EQ can lower the volume of those frequencies. Lowering the volume of low frequencies can help reduce hums or rumbles, while reducing higher frequencies addresses hisses or high-pitched sounds. This method offers precise control over specific frequency ranges to remove echo from audio. Users can effectively reduce background noise without significantly impacting the overall audio quality.

Follow these steps to use Equalizer in Sony Vegas:

Step 1. Select "Track FX" from the track header and choose "Audio Events FX."

Step 2. Select "Track EQ" to access the EQ controls. In the EQ controls, you'll see a graphical representation of frequency bands as a flat line connected by four dots. Each dot corresponds to a specific frequency range, with the first dot representing lower frequencies and the fourth dot representing higher frequencies.

Step 3. Click and drag the dots to manipulate the volume levels of the corresponding frequency ranges.

Step 4. Lowering the volume of lower frequencies can reduce the background noise like hums or rumbles. Reducing higher frequencies can mitigate hisses or other high-pitch sounds.

Step 5. Select the desired frequency range.

Step 6. Preview the audio after making EQ adjustments to assess the effectiveness of your changes.

Step 7. Listen carefully and make additional adjustments if necessary to achieve the desired balance between background noise reduction and maintaining the clarity of the audio.
