Hello, my file is exporting to NW.JS and the audio and music is not playing on export though it works in the preview. The file formats for the music are .webm, and .mp3. I saw a forum similar to this, but it did not work with their suggestions.
Develop games in your browser. Powerful, performant & highly capable.
MP3 isn't recommended for Construct 2.
Also, webm is a rather odd format for audio and is not intended for BGM/music/sound use.
Anyhow, the answer is:
Don't use mp3 or webm. Use OGG and/or AAC. A good tool for OGG is Audacity, you can open audio files in it and export them as OGG.
