Reduction Strength

Spectral subtraction (Boll 1979): noise profile estimated from first 0.5s, subtracted bin-by-bin from 1024-bin FFT frames with 75% overlap. Original phase preserved.

About This Tool

This page targets the query "noise reduction for podcasts" — covering the complete podcast audio cleanup workflow from noise removal through normalization and export. Unlike the noise-reducer-for-podcasts page (tool-focused), this page takes a workflow-first approach: a step-by-step production chain, a noise problem reference table, podcast loudness standards by platform, and recording tips to minimize noise at the source. All processing runs locally in your browser — no upload, no server.

The Complete Podcast Audio Cleanup Workflow

Follow this workflow to get professional-sounding podcast audio:

  1. Step 1 — Noise Reduction (this tool): Remove background noise first, before any other processing. Upload your raw recording and apply spectral subtraction to eliminate hiss, hum, and room noise.
  2. Step 2 — Volume Normalization: Use our Podcast Normalizer to bring your audio to -16 LUFS — the standard for Apple Podcasts and Spotify.
  3. Step 3 — Remove Silence: Use our Silence Remover to automatically cut out long pauses and dead air.
  4. Step 4 — Trim: Use our Audio Trimmer to cut the intro and outro to the right length.

Podcast Loudness Standards

After noise reduction, normalize your podcast to meet platform standards:

PlatformTarget LoudnessMax True Peak
Apple Podcasts-16 LUFS-1 dBTP
Spotify-14 LUFS-1 dBTP
YouTube-14 LUFS-1 dBTP
Anchor / Buzzsprout-16 LUFS-1 dBTP

Use our Volume Normalizer to hit these targets precisely after noise reduction.

Recording Tips to Minimize Noise

The best noise reduction starts before you hit record:

  • Record in a quiet room: Close windows, turn off fans and AC, and choose a room with soft furnishings to absorb echo.
  • Use a dynamic microphone: Dynamic mics (like the Shure SM7B or SM58) reject more background noise than condenser mics.
  • Record a noise tail: Start each recording with 1–2 seconds of silence before speaking — this gives the noise reducer a clean noise profile.
  • Use a pop filter: Reduces plosives and breath noise that noise reduction cannot fix.
  • Check your gain staging: Recording too quietly increases the noise floor relative to your signal. Aim for peaks around -12 dBFS.
