Audio Joiner — Merge DASH Audio Files Extension

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.

Paul Roth (ID: 000000e7baa85a29) Voted 5 ★ - Updated 04/11/2020 Intuitive right out of the box. Took me a little experimenting to grasp where my joined file went and how to manage it. Joined file is compatible with Chromecast and easily casts to my Google home nest device. Casting from Chrome only plays a single file without human intervention. Quickly join a play list folder of audio files and play them as 1 file with or without silence between joined files.
