Audio Joiner — Merge Audio Files
There has been an increasing interest in streaming segmented media tracks to eliminate the buffering delay and provide a responsive player even on low-quality networks. This extension aims to solve merging these segmented tracks locally to get a single playable track that can be used with any normal media player. The user has an option to set or remove the delay between tracks before joining them together. To prevent losing the quality first each track is converted to a PCM buffer and then all tracks in the order that the user is defined as being merged with the optional delay that is provided. The output format of this extension is WAV (equal to "audio/wav" mime type). This format is lossless but it is pretty large. You can always use online tools or browser extensions to convert the WAV format to a lossy but compressed format like MP3.
This extension works completely offline. There is no data transmission from or to a remote service.
This extension does not use any native complements to do the joining job similar to some other counterparts. It uses the powerful built-in AudioContext component of HTML5.
