What does the Audio Joiner do?
The Audio Joiner builds a single timeline from several uploads. You can add up to ten files total—each must be audio/* and up to fifty megabytes—by selecting or dropping them repeatedly until the cap is reached. The numbered list shows filename and size in kilobytes; arrow buttons move a row earlier or later so the final mix follows your story order, and trash removes a mistake without clearing the whole queue. Output format defaults to Match first file, which sends the first clip’s extension lowercased to the server (falling back to mp3 if there is no extension), or you can override to MP3, WAV, or OGG only. Join Audio Files stays disabled until at least two clips are present. Upload uses the shared media job pipeline with progress and a single signed download when processing completes.
Limits and quality
This is a straight concatenate in list order, not a beat-matched DJ crossfade. Level differences, sample-rate, or codec mismatches are handled server-side during encode; expect re-encoding when formats differ. For a predictable container use the MP3, WAV, or OGG buttons; Match first file only forwards the first clip’s filename extension (or mp3 if missing), and the job must succeed on the server for that extension.
Privacy
Every queued file uploads to Dynamic Duniya for the join job. Do not merge confidential interviews, DRM-protected purchases, or third-party music you are not licensed to redistribute.
