How to Clean Up Zoom Call Recordings Like a Pro

Zoom call recordings are a minefield for background noise. Your guest joins from a home office with a noisy air conditioner. Another participant has a mechanical keyboard they use throughout the call. Someone's dog barks at the 23-minute mark. By the time you export the recording, you have a 45-minute file that sounds like it was recorded in a server room.

This guide shows you exactly how to clean up Zoom recordings — removing background noise from all participants while preserving speech clarity — using noise-remover.com's Call preset, which was specifically designed for this use case.

Why Zoom recordings have so much noise

Zoom applies its own noise suppression during live calls, but this suppression is designed for intelligibility during the call — not for archival quality. The exported recording often has residual noise, compression artefacts from the video codec applied to the audio, and inconsistent levels across participants recorded in different environments.

Additionally, Zoom's suppression is conservative by design — it would rather let some noise through than risk cutting off speech. The result is a recording that sounds acceptable during the call but reveals all its flaws when you listen back with headphones or import it into editing software.

Step-by-step: cleaning a Zoom recording

Step 1: Export from Zoom in the right format. In Zoom's recording settings, enable "Record separate audio files for each participant" if you want to process each speaker independently for maximum control. If you want a single file, export the combined recording as an M4A or MP4.

Step 2: Upload to noise-remover.com. Go to the Studio page and upload your recording. MP4, M4A, and MP3 files are all accepted. If you have separate per-participant audio files, process each one individually for best results.

Step 3: Select the Call preset. This is critical. The Call preset applies maximum noise suppression tuned for multi-environment speech recordings. It aggressively removes air conditioning, fan noise, keyboard clicks, and room reverb while maintaining speech intelligibility across different voice characteristics.

Step 4: Process and compare. Use the Before/After player to verify the improvement. For typical Zoom recordings, you'll hear a dramatic reduction in background noise while speech remains clear and natural.

Step 5: Download and re-import. Download the clean audio (WAV for maximum quality) and replace the original audio track in your video editing software. In DaVinci Resolve or Premiere Pro, simply unlink the audio from the video, delete the original audio track, and drag in the processed WAV file.

Tips specific to Zoom recordings

Process the longest participant's audio first to verify results before processing all tracks. If one participant has particularly bad noise (coffee shop background, for example), they may benefit from two passes — once with Call preset, then again if residual noise remains.

For podcast-style interviews recorded on Zoom, the Podcast preset can produce warmer, more broadcast-ready results than the Call preset if the environmental noise isn't too heavy. Try both and choose the one that sounds better for your specific recording.

Normalise levels after processing. Zoom recordings from different participants often have significantly different volume levels. After noise removal, use a loudness normalisation tool (Auphonic, or your DAW's built-in normaliser) to bring all participants to a consistent loudness level.

The result

A properly processed Zoom recording, cleaned with the Call preset and normalised, should be indistinguishable from a professionally recorded interview in terms of background noise. The process takes under 5 minutes for most recordings — far less time than manually editing out noise frame by frame.
