Hi.
Please see my attached picture.
Is there a method to show a .ogg file waveform with code ? Or something else when you play an .ogg file ! I need to display something fun when the music file is played.
Many thanks.

It is probably possible using CreateMemblockFromSound() , to determine what the audio does at what point in the file at what playback time and then change bars or blocks in real-time based upon playback. But... not sure how to technically do it lol. I haven't dug into using memblocks yet. Really should though.

From manual:

"The duration of the sound can be calculated with the following formula, numFrames/samplesPerSecond"

..so I guess you could create a couple of bar images that make up a waveform using memblock, with the length / size calculated using the duration formula above.

I posted an example of doing this a few months ago. Loading a peice of music then getting average audio levels and then displaying the waveform and bargraphs of the volume etc...

Should still be on here somewhere.

Its this thread from 1 month ago:

https://forum.thegamecreators.com/thread/222791

It uses loadsound() but you can just change that to loadsoundogg() and then be able to get audio levels.

Preben E did an example to which I could post up if wanted which is closer to what you want....with bars that animate with the music instead of a wave.

Bengismo: Naaa the code is part of GameGuru Loader , but when you emailed me about how to do it , you said you did not have GG Loader , so i made that sample just for you, and its never been published

Anyway you can all have it, i have attached the project here.

Its the same as used in this video:



It also have the beat detection if you need object to react to the beat (global beaton = 0) when beaton = 1 then do something

If you already have GameGuru Loader , you can just copy the code from there.

The code that i posted was written from scratch so not game guru loader related at all.

In the case of Prebens though...it looked much better than mine i would have recommended anyone using that as mine just drawed the sound waveform and averaged over 100ms to give a sound level. Not quite as exciting as the visualisation in prebens work. Mine didnt do beat detection either.

And i do have ggloader now... Worth it for the PBR rendering alone!

Bengismo: did not see your code, it was just your comment:

So i just wanted to post it before you, as i never published it anywhere , so NP dude.

Never tried it but give it a go using "LoadSoundOGG" instead of "LoadSound" , let us know if it works
