7 Pro Tips to Get Better Audio with Lexis Audio Editor

How to Remove Noise and Improve Voice Quality in Lexis Audio Editor

Improving voice clarity and removing background noise in mobile recordings is fast with Lexis Audio Editor. This guide gives a concise, step-by-step workflow you can follow on Android to clean up voice recordings and make them sound professional.

1. Prepare the project

1. Open file: Tap the folder icon and load your recording (WAV/MP3/AAC supported).
2. Duplicate a backup: Use Edit → Copy and Paste to create a backup track on a new file — always keep an untouched original.

2. Trim and remove problem sections

1. Listen quickly: Play through and note time ranges with obvious noise or mistakes.
2. Select and cut: Drag to select unwanted segments and use the Cut tool (scissors) to remove them. For short clicks/pops, zoom in and cut tightly around the artifact.

3. Normalize levels

1. Select entire track: Tap the track or use Select All.
2. Normalize: Use Effects → Normalize to set consistent peak/average level. Choose a target around -3 dB to leave headroom for processing.

4. Apply noise reduction

Lexis has a basic noise removal workflow—get the cleanest result by isolating a noise profile first.

1. Find a noise-only section: Locate a silent portion where only background noise is present (breath, hum, hiss).
2. Select noise sample: Zoom and select that noise-only region.
3. Noise reduction: Effects → Noise Removal (or Noise Reduction). Use the selected sample as the noise profile if prompted. Start with low-to-moderate reduction settings to avoid artifacts.
4. Preview & adjust: Apply, listen, and undo if it introduces underwater or metallic tones. Repeat with gentler settings if needed.

5. Reduce sibilance and harshness

1. Manual editing: Zoom into sibilant consonants (“s”, “sh”) and reduce amplitude with the gain tool or use the Envelope tool to lower those peaks slightly.
2. De-esser workaround: If there’s no built-in de-esser, copy the track, apply a high-frequency cut (Effects → Equalizer) on the copy, then crossfade only over sibilant spots.

6. Equalization for clarity and warmth

1. Low-cut (high-pass): Apply a gentle high-pass filter at 80–120 Hz to remove rumble and mic handling noise.
2. Boost presence: Slightly boost frequencies around 2–5 kHz (+2 to +4 dB) to enhance intelligibility.
3. Tame harsh highs: If the top end is brittle, reduce around 8–12 kHz by -1 to -3 dB. Use small, surgical adjustments and preview often.

7. Compression for consistent level

1. Mild compression: Effects → Compressor. Set ratio 2:1 to 4:1, attack 5–20 ms, release 50–150 ms, and adjust threshold so the compressor reduces gain only on louder passages.
2. Make-up gain: Apply a small make-up gain to restore perceived loudness after compression. Keep peaks below 0 dB (recommended peak ~ -3 dB).

8. Remove breaths and unwanted vocal noises

1. Zoom & select breaths: Identify large breaths and reduce their amplitude manually or cut them if unnatural.
2. Use fade handles: Apply short fades to avoid clicks when removing or lowering breaths.

9. Final polish

1. Listen on multiple devices: Test on headphones, phone speaker, and laptop to ensure balance.
2. Apply final normalize/limiter: Normalize to -1 to -3 dB or apply a soft limiter to catch remaining peaks.
3. Export: File → Save as and choose WAV for highest quality or MP3 with a suitable bitrate (192–320 kbps) for distribution.

10. Quick checklist before exporting

• Backup original saved
• Noise reduction applied gently
• EQ enhances clarity without harshness
• Compression controlled and natural
• Breaths and clicks cleaned
• Peaks below -1 dB

Follow these steps to reduce noise and improve voice quality using Lexis Audio Editor. For problematic recordings, repeat gentle passes of noise reduction and EQ rather than extreme single-step changes to avoid artifacts.
