I would like to clarify a couple of questions about sound formats:

1. Is it possible to use the ogg format of sounds directly, not wav? Because if I add ogg sounds to assets folder they are added into Assets.blobs, not in Assets.sounds.

2. When I export to HTML5, all the wav sounds are converted to ogg, but when I use the android native target non-converted wav sounds are added to apk file, which causes the file size is increased dramatically. Is it possible to use ogg in android native target?

khamake requires wav files so the files can be converted to whatever works best on the target system. If you want to use lossy compression set the quality parameter for your audio assets ala https://github.com/Kha-Samples/BlocksFromHeaven/blob/master/khafile.js

@robert thanks for the tip, Robert! It works.

btw, it is probably worthwhile to output a warning to the logs if the wav format does not match the required one (sample rate: 44100Hz 16 bit). Accidentally I had one wav that was not of this format, and I was getting just a black screen on the android (html5 target works fine even in this case).

I'd rather make that wav work. Please create an issue on GitHub.

@robert Hmm ... I tried to attach this wav to an empty project, and everything seems to work as it should on the android. Maybe the problem was not in this file... I'll try to investigate more and try to localize the problem in a empty project and then raise an issue on github.

I'm not completely sure if this is 100% related so sorry if this is off topic, but I have a project that plays audio fine on the html and osx version. However, when I export to ios, there is no sound. I was wondering if this is maybe a similar issue to the file format, or if there is something special about ios.

Don't know about any iOS audio issues. Please create an issue on GitHub and provide all the details.
