Basics Level

Normalize

The whole range to one target level.

Normalize in jd.Edit

What the effect is for

Recordings rarely arrive at the right level: voice memos are quiet, a USB interface was set too cautiously, an import from another app sits 10 dB below the rest. Normalize raises or lowers the whole range by one fixed factor so it lands on a defined level.

Two yardsticks are available. Peak aligns the loudest spot to 0, −1 or −3 dBFS — the classic, lossless way. Loudness (RMS) aligns the average level and makes recordings comparably loud; a clipping guard holds the gain back if peaks would otherwise exceed 0 dBFS.

Benefits

  • ✓Measured up front: the current level sits on the LED meter, the change in dB next to it — no surprise after tapping.
  • ✓Non-destructive: Undo takes the step back, the original file stays untouched.
  • ✓Works on the selection or the whole file — for one quiet sentence as well as the entire episode.
  • ✓Looped preview: Play runs the range with the change; mode and target are audible immediately.

When it makes sense

Even out voice memos

Lift a quiet memo to −1 dBFS before cutting or sending it.

Before exporting

The last step before WAV or MP3 so the file arrives equally loud everywhere.

Several recordings

Bring interview parts from different sessions to −20 dB RMS — then they sound like one piece.

Controls

ModePeak or loudness (RMS) — rocker switch.
Target levelPeak: 0, −1, −3 dBFS. Loudness: −16, −20, −23 dB.
DisplayCurrent level with target marker, the change in dB below.

Tips

💡−1 dBFS is the safe default: fully driven, with headroom for MP3 encoding.

💡For podcast episodes −20 dB RMS is a good starting point; leveler and limiter do the fine work.

Chain order: High-pass → Leveler → Compressor → De-Esser → SoundsBetter → Limiter. The effects list can be reordered with “Reorder”.
