There is a growing interest in streaming media tracks in segments to eliminate buffering delays and ensure a responsive player, even on low-quality networks. This extension is designed to address merging these DASH tracks by locally merging them into a single playable track, compatible with any standard media player. Users can set or remove delays between tracks before merging. To maintain quality, each track is initially converted to a PCM buffer, and then they are merged in the user-defined order with optional delays. The output format of this extension is WAV (equivalent to the "audio/wav" MIME type), which is a lossless but large format. To reduce file size, users can use online tools or browser extensions to convert the WAV format to a lossy but compressed format like MP3.

Notes:
- This extension operates entirely offline, with no data transmitted to or from a remote service.
- Unlike some counterparts, this extension does not rely on native complements for the merging process. Instead, it leverages the robust built-in AudioContext component of HTML5.
