    Method and principles

    Tracks are resampled to the selected rate and channel layout.

    Original uses the first track.

    A crossfade overlaps the end of one track with the start of the next.

    Practical example

    Two 30-second tracks last about 60 seconds together, or 58 seconds with a two-second crossfade.

    Usage scenario

    Input
    WAV A [2 s] + WAV B [3 s]; 0 s
    Result
    WAV [≈ 5 s]

    Formats and limits

    2–20 files, 500 MB and 2 hours combined before overlaps. Crossfade up to five seconds, shorter than every track. Volume is not normalised automatically.

    Limits and checks

    Files are used only for the requested processing. Queued and running jobs expire within 2 hours; results within 30 minutes or when you reset the tool. Check the result before use.
