Bring a track to -14 LUFS for streaming without pushing the true peak over -1 dBTP
Processed in your browser. Nothing is uploaded. Checked against sources on 17 Oct 2026.Spotify adjusts every track to -14 LUFS, measured with ITU-R BS.1770, so a master that is quieter is lifted and one that is louder is turned down. Drop the track here to see its integrated loudness and true peak, then press once to set it to -14 LUFS. If reaching the target would push the true peak past -1 dBTP, the gain stops there and the page says which loudness it reached.

Peak normalising makes the loudest sample hit a level; loudness normalising makes the whole file sound as loud as a target. Streaming services and broadcasters work in loudness, measured in LUFS (loudness units relative to full scale), which is why two songs peaking at the same level can still sound very different.
Which target. Spotify turns every track to -14 LUFS. Apple Podcasts asks for about -16 LKFS with a true peak no higher than -1 dB. EBU R 128 sets European broadcast at -23 LUFS. Any value from -40 to -5 can be typed in.
What changes, and what does not. One gain is applied to the whole file, so the dynamics stay exactly as they were. Nothing is compressed or limited. When reaching the target would push the true peak above -1 dBTP, the gain stops at that ceiling and the page says which loudness it reached, so you can decide whether to compress the recording first. The result is a 16-bit WAV at the original sample rate.

Spotify adjusts tracks to -14 LUFS, according to its loudness normalization page. A louder master is turned down and a quieter one is lifted, as far as its peaks allow. Normalising to -14 here shows what listeners will hear, and keeps the true peak under -1 dBTP for lossy encoding.
Apple Podcasts recommends about -16 LKFS, plus or minus one decibel, with a true peak no higher than -1 dB FS. LKFS and LUFS are the same unit. Choose -16 here and every episode lands at the same level, so listeners stop reaching for the volume between shows.
Reaching the target would have pushed the true peak above -1 dBTP, which distorts after MP3 or AAC encoding. The gain stops at the ceiling and the page shows the loudness actually reached. Compress or limit the recording in an editor first, or switch the ceiling off if you accept clipping.
No. Peak normalization lifts the single loudest sample to a level, so a recording with one loud clap stays quiet overall. Loudness normalization measures the whole programme as ears hear it. Two files normalised to -14 LUFS sound equally loud; two peak-normalised files often do not.
