- Use the Gain Slider: For finer control, use the gain slider located below the effects button on the track control panel. Drag left or right to decrease or increase gain. Holding the Shift key while dragging allows for more granular control.
- Balancing Left and Right Channels: If you’re working with a stereo track and need to adjust the balance between left and right channels, use the Pan option located just below the gain slider.
- Listening and Adjusting: Play the track to listen to the changes. Adjust the sliders until you achieve the desired balance and consistency in sound levels.
- Finalize Your Edits: Once satisfied with the level adjustments, you can proceed with other editing tasks or export your project.

- Applying Noise Reduction: After setting the noise profile, select the entire audio clip. Return to the “Effects” tab and click on “Noise Reduction” again. Here, you will need to adjust the settings to balance between noise removal and maintaining audio quality. This step is crucial for effective noise reduction.
- Preview and Apply: Before finalizing, use the Preview option to listen to a segment of the audio post-noise reduction. This helps you gauge the effectiveness of the noise reduction. If satisfied, click on “OK” to apply the noise reduction to the entire file.

Advanced Techniques for Audio Cleanup
Spectral editing in Audacity is an advanced technique that allows you to visually identify and target specific unwanted sounds, like clicks, pops, or background hums, in your audio recordings. Here’s a step-by-step guide to using spectral editing in Audacity:
- Open your audio file in Audacity and switch to the Spectrogram view by clicking on the track name and selecting ‘Spectrogram’ from the dropdown menu.
- Identify the unwanted noise in the spectrogram view. This will typically show up as distinct lines or patterns that differ from the rest of the audio spectrum.
- Make a rough selection around the unwanted noise. Use the mouse to click and drag around the area where the noise is visible in the spectrogram.
- Zoom in on the offending frequencies by clicking and dragging on the vertical scale of the spectrogram. This allows you to see the frequencies in more detail and make a more precise selection.
- Adjust the selection to precisely cover the unwanted noise. Hover over the center frequency line or the upper/lower boundary of your selection until the double-triangle cursor appears, then click and drag to adjust. This step ensures that your filter will target only the noise without affecting the desired audio.
- Apply a notch filter effect by selecting ‘Effect’ > ‘Spectral edit multi-tool’. This effect will remove or reduce the noise in the selected frequency range.
- Listen to the audio to confirm that the unwanted noise has been successfully removed or reduced. If necessary, you can undo the effect and make adjustments to your selection before reapplying the filter.
To use the compression tool in Audacity to achieve consistent audio volume, follow these steps:
- Open Your Track: Load the audio track you want to work with in Audacity.
- Access Compression Tool: Navigate to the ‘Effect’ menu and select ‘Compressor’.
- Adjust Threshold: Set the threshold level. This determines the volume level at which compression begins. A lower threshold will apply compression to more of your audio.
- Set Noise Floor: The noise floor setting helps in avoiding amplifying noise during quiet sections. Adjust it to avoid raising the volume of background noise.
- Ratio Settings: The ratio determines how much compression is applied. A higher ratio results in more compression. A good starting point can be a ratio of 2:1 or 3:1.
- Attack and Release Times: Adjust the attack time (how quickly compression starts) and release time (how quickly it stops). Shorter attack times are good for consistent volume, while longer release times avoid abrupt changes.
- Preview and Apply: Use the ‘Preview’ button to listen to a sample of the compression effect. Adjust settings if needed and then click ‘OK’ to apply the compression to your track.
