audio-edit — Traditional AI Model

Audio Edit cuts a sound to the part you want, fits it to a length - cut a long track to your video with a short fade at the cut, or loop a short one with smooth crossfaded seams - lowers or mutes chosen stretches, and fades it in or out. Connect a video to fit the sound to it exactly. Put the result on the video with Audio Replace, or mix it with others in Audio Mix. CPU.

Inputs & Outputs

SoundInputsound

The sound to edit

VideoInputvideooptional

Only its length is used: length=video fits to it

SoundOutputsound

The edited sound (WAV)

Parameters

lengthstringdefault keepoptions: keep, video, fixed

What sets the length. Keep: as trimmed. Video: the connected video. Fixed: duration_sec.

fitstringdefault loopoptions: loop, pad, keep

A sound shorter than the length: loop it, pad with silence, or keep it short.

rangesstringdefault

Lower or mute stretches: start-end:dB separated by commas, e.g. 2.0-4.5:-12, 8-end:mute.

Comma-separated start-end:dB items on the fitted timeline (seconds from the start of the result). end may be "end"; dB from -60 to +12, or "mute". Overlapping ranges multiply. A range running past the end is clipped there; one starting at or after the end fails the run.

start_secfloatdefault 0range 0–600

Where to start, in seconds into the sound.

end_secfloatdefault 0range 0–600

Where to stop, in seconds into the sound. 0 keeps it to the end.

duration_secfloatdefault 0range 0–600

The length when length is fixed.

fade_in_secfloatdefault 0range 0–60

Fade-in at the start.

fade_out_secfloatdefault 0range 0–60

Fade-out at the end.

volumefloatdefault 1range 0–2

Overall level. 1 keeps it, 0 mutes it.

normalizestringdefault offoptions: off, -14, -16, -23

Bring the result to a loudness target.

'off' (default) keeps the level; '-14' / '-16' / '-23' normalize to that LUFS with a -1.5 dBTP true-peak ceiling (the same pass as Audio Finish).

cut_fade_secfloatdefault 0.5range 0–10advanced

Fade applied at the end only when the length cut the sound.

loop_crossfade_secfloatdefault 0.3range 0–5advanced

Crossfade at each loop seam (0 = hard joins).

ramp_msfloatdefault 50range 0–1000advanced

How smoothly a range fades in and out, in milliseconds.
