Create Seamless Loop of Audio - Web

QUESTION

Create Seamless Loop of Audio - Web

Asked 2017-Nov-24 at 16:36

I want to create a seamless loop of an audio file. But in all approaches I used so far, there was a noticeable gap between end & start.

This is what I tried so far:

First approach was to use the audio in the HTML and it loops but there is still a noticeable delay when going from the end of the track to the beginning.

You can use the Web Audio API instead. There are a couple of caveats with this, but it will allow you to loop accurately down to the single sample level.

The caveats are that you have to load the entire file into memory. This may not be practical with large files. If the files are only a few seconds it should however not be any problem.

The second is that you have to write control buttons manually (if needed) as the API has a low-level approach. This means play, pause/stop, mute, volume etc. Scanning and possibly pausing can be a challenge of their own.

And lastly, not all browsers support Web Audio API - in this case you will have to fallback to the regular Audio API or even Flash, but if your target is modern browsers this should not be a major problem nowadays.

Example

This will load a 4 bar drum-loop and play without any gap when looped. The main steps are:

It loads the audio from a CORS enabled source (this is important, either use the same domain as your page or set up the external server to allow for cross-origin usage as Dropbox does for us in this example).
AudioContext then decodes the loaded file
The decoded file is used for the source node
The source node is connected to an output
Looping is enabled and the buffer is played from memory.
