[Request] Recorder.js - Plugin to Record/Export audio in .Wav

Construct 3 already has a Game Recorder plugin which can do that.

And how? How can it save to .wav ?

I was only able to save it in .webm (video). If i set Video=none the on stop recording get the record file to save is never trigered.

How can i export the audio recorded in runtime into .wav ?

Set the video format to "none" and set the audio format to one of the options. AFAIK browsers only support encoding those formats, not WAV, but it should be easy to find a tool to decompress a WebM to WAV if you really need it uncompressed.

Why do you need a WAV? Most things support compressed formats these days, and their compression is excellent quality.

For an audio APP, to add effects, mix,etc... and export in .wav , and the idea is give 3 options Wav, Mp3 and .OGG.

But atleast wav, uncompresed, so after that people can use any conversion tool or whatever.

I think this is for a download application vs web app (right?). So - you may be able to use npm modules if you export (and there are other ways if it is for web.)

If that's the case you may look at this:

npmjs.com/package/audiobuffer-to-wav

You would then add an appropriate JS or plugin to call it (after loading your locally recorded file, getting it from a buffer, etc.)

In my case is for an Standalone app, using NW.JS. So, i guess a plugin that can record and save to .wav .

About what you said no idea, i have 0 skills of code/js.

Ah, that would be difficult then. Also for this module to work, you need to get the raw audio in a buffer, which I am not sure how to do from the C3 Game Recorder (except something like loading and decoding the recorded webm file which seems like a pain also.)

Wave audio files are basically a wrapper with some header information around the plain PCM audio. All audio formats have to be converted back to PCM to be played by a computer anyway, that's one of the reasons that pretty much everything supports wave files.

In terms of getting PCM audio you can use the web audio API. It provides a method that takes any audio file supported by the platform and converts it into an "AudioBuffer" object which is a loose wrapper around the PCM data. Once you have that you basically need to find a way to pack it into a wave file.

I had a quick look and there's a rough method for creating a wave audio file here. It could do with tidying up, and it needs some minor adaptation but it's quite doable.

Most of this requires some sort of JS knowledge unfortunately...
