You can set the crossfade duration from 0 seconds (no crossfade, just concatenation) to 10 seconds. The slider lets you adjust in 0.5-second increments for precise control.
You can merge up to 20 audio files at once. The maximum total output duration is 30 minutes to ensure smooth browser-based processing.
