Audio Concat
Join 2 to 12 audio clips into one file, in order, with silence between them. Wire an array into `clips` (an iterator's collected clips) or the discrete `audio_1`..`audio_6` ports; a wired `clips` array wins outright and the discrete ports are ignored (no silent merge). `gap` is the uniform silence between clips in seconds; `gaps` (e.g. \"0.3, 0.5\") sets each join individually and must name exactly one value per join. Every clip is resampled to one format first (default 48 kHz stereo). Free: deterministic processing, content-addressed output.

Description
Join 2 to 12 audio clips into one file, in order, with silence between them. Wire an array into clips (an iterator's collected clips) or the discrete audio_1..audio_6 ports; a wired clips array wins outright and the discrete ports are ignored (no silent merge). gap is the uniform silence between clips in seconds; gaps (e.g. "0.3, 0.5") sets each join individually and must name exactly one value per join. Every clip is resampled to one format first (default 48 kHz stereo). Free: deterministic processing, content-addressed output.

What it is for
Join phrases into one track with controlled gaps, without a stack of trim nodes or a trip to an audio editor.
Wiring
Wire an array into clips (for example an iterator's collected TTS lines), or wire the discrete audio_1 to audio_6 ports. When clips is wired it wins outright and the discrete ports are ignored, never merged. 2 to 12 clips. A discrete port that receives more than one clip is refused rather than silently dropping the extras.
Settings
- Gap (seconds, 0 to 10): silence between every pair of clips.
- Per-join gaps: a comma list such as
0.3, 0.5, 0.2that sets each join individually. It must name exactly one value per join (clips minus one) and overrides Gap. - Sample rate (48000 default, 44100, 24000) and Channels (stereo default, mono): every clip is converted to this one format before joining.
- Format: mp3 (default) or wav.
Free, and why
Free set, no Run button, refreshes when anything downstream runs. The output is content-addressed by the clip urls, their order and the settings, so an unchanged re-run reuses the last file.
