Multi-Speaker Leveler

Drop in 2+ voice tracks. Each gets normalised to the same loudness target, then mixed into a single file.

About this multi-speaker leveler

Interview podcasts often have a host and a guest recorded separately — different microphones, different rooms, different speaking styles. The result: one person sounds twice as loud as the other. This tool runs each voice track through broadcast-grade loudness normalisation independently so they match, then optionally mixes them down to a single file.

Drop in 2-4 voice tracks (host, guest, etc.) and the tool produces an evenly-leveled result. We don't analyse or index your audio.

How to level multiple speakers

  1. 01

    Drop in voice tracks

    One per speaker. Best when each track has just one voice (separate-mic interviews).

  2. 02

    Pick a target

    -16 LUFS is the AES podcast standard. -19 LUFS for stereo music-rich shows.

  3. 03

    Render the leveled mix

    Each track is normalised, then mixed down. Output is a single MP3.

Why use this leveler

  • Broadcast-grade loudness normalisation per track
  • 2 to 4 speaker tracks supported
  • Optional final mix to single MP3
  • Output keeps a clean 192k MP3
  • Free, private, no install
  • Useful for interview podcasts, radio shows, two-way conversations

Multi-speaker FAQ

What if my host + guest are on the same track?

Then this tool can only treat them as one voice. For separate leveling you need separate recordings — common when each speaker uses their own mic with multi-track recording software like Riverside or Zencastr.

What target should I pick?

-16 LUFS for spoken-word podcasts (AES recommendation). -19 LUFS for music-heavy stereo shows. -23 LUFS for broadcast TV.

Will it suppress crosstalk and bleed?

No — this is loudness normalisation only. For crosstalk suppression on multi-mic recordings, use the Noise Gate tool first to clean each track, then level here.

Is my file kept private?

Yes. We don't analyse or index your audio.
