Hi All,  
I have an SWF which requires the loading of several external sounds (MP3 files). I am able to load and play these files just fine when testing locally, by way of creating a new Sound() and playing them as needed (streaming).

However, I worry that the larger sound files will eventually fall out of sync with the movie if they haven’t buffered enough data.

Is there a way for me to load all my sound files at the start before my movie starts playing, and then only call a specific one as needed later on in the movie?

Just a note, importing my sounds into the library is not really feasible as the sounds will be updated frequently.

Thanks!
