Build with Audio Pad.
Add leading and trailing silence to an audio clip, pad it up to a minimum length, and resample it.

Add leading and trailing silence to an audio clip, pad it up to a minimum length, and resample it. Use the playground to set up a single step, then open a workflow when you want to connect more tools.
Inputs explained
- Audio (required)
- Set the audio used by this model. Type: audio.
- Lead silence (s) (optional)
- Set the lead silence (s) used by this model. Type: number. Default: 0.
- Tail silence (s) (optional)
- Set the tail silence (s) used by this model. Type: number. Default: 0.
- Minimum duration (s; blank = none) (optional)
- Set the minimum duration (s; blank = none) used by this model. Type: number.
- Sample rate (optional)
- Set the sample rate used by this model. Type: text. Options: 48000, 44100, 24000, keep. Default: "48000".
- Channels (optional)
- Set the channels used by this model. Type: text. Options: stereo, mono, keep. Default: "stereo".
- Format (optional)
- Set the format used by this model. Type: text. Options: mp3, wav. Default: "mp3".
Tips before you run
Start with the default settings and change one input at a time. Keep the result you like on your board so the next step can use it.
If you add a reference file, use a link the workflow can read. Check the inputs and credit estimate on the board before starting a run.
Working with this model
What it is for
Reference-audio prep in one node. Seedance's @Audio reference should be 48 kHz stereo and at least 1.8s long. Set Minimum duration to 1.8; the 48 kHz stereo default does the rest.
Leave Lead at 0, the default, when the audio is a lip sync reference. In a Seedance edit, the edited clip's own audio on Reference Audio drives the timing of the mouth, so it has to start exactly where the clip starts: any lead makes every mouth shape land late by that much. Tail and Minimum duration only pad the end, so they never move the start. A lead is for a generated take, where it gives the shot a beat before the first word.
Settings
- Lead silence (seconds, 0 to 30): silence before the audio.
- Tail silence (seconds, 0 to 30): silence after it.
- Minimum duration (seconds, blank = none): pads the end until the whole file is at least this long. It counts the lead and the tail. A clip already longer is left at its length, never cut.
- Sample rate: 48000 (default), 44100, 24000, or keep.
- Channels: stereo (default), mono, or keep. Mono sources are duplicated to both channels.
- Format: mp3 (default) or wav.
Out-of-range values are refused with the number, never clamped.
Free, and why
Free set, no Run button, refreshes when anything downstream runs. The output is content-addressed, so an unchanged re-run reuses the last file.
Common questions
How do I use Audio Pad on Wireflow?
Set the inputs above and choose Open in a workflow. Sign in to save your board, then check its credit estimate before you run.
Can I use Audio Pad through an API?
Yes. Save a workflow with this model, then call the Wireflow run API with its workflow ID. The API tab has examples you can copy.
What changes the credit price?
The price shown uses the model defaults. Your inputs and model settings can change the total. The workflow shows an estimate before you run.
Can I connect this to another model?
Yes. Open it in a workflow and connect its output to another node with a matching input type.
