Questions about audio

1. How do I randomly pick from a set of music files to play (not looping) at start of layout and then after it finishes, select another one from same set, and so on.

2. If I have a 5mb ogg file and import it to my game, can I still make the size of ogg file smaller after it is added to the capx? bottomline is I don't want a big capx size and I would like to know how to make the sound files as small as possible, possibly as small 200kb per ogg file.

anyone?

I would use:

play by name "your_sound_files_renamed_to_use_an_index"&int(random(howmanysoundfilesyougot))

system wait howeverlongthatfileis ms, play foo

if you download an ogg converter or use Audacity your can set the file compression quality from 1-10. With 1 being the lowest quality and 10 being the best quality. I would recommend quality 4 as that will be the best size to sound ration.. quality lower than 4 get bad pretty fast and leaves all sorts of sound artifacts...

media human has a good free app..

download the converter here...

C: System: At start of layout <----I think this is wrong but not sure what to replace it with

A: Audio: Play int(random(5)) from Music

A: System: Wait "Audio.Duration" secs <--- duration can't take 0 parameters, tried "Audio.Playbacktime" same issue

How can I set the duration if the music files are not same duration?

thanks. please check your pm.

Audio.Duration("yourtag")

it all depends on the duration of the audio.

a rough estimate

1 min audio uncompressed (like wav or aif) = 10MB

1 min audio compressed (mp3, ogg) = 1MB

but with ogg you can bring the compression down with quality and make the file sizes smaller.

you have to play with this setting.. but you are probably not going get much smaller than a 1MB/per min and sound good. Depending on what it is you might be able to get down to 900/800kb per min...
