Playing audio data recorded with flash object in Storyline?

Hello,

How can I play audio files or ByteArray data by executing javascript in Storyline ? I got Flash object which record mic audio then create ByteArray data. I found some solution how to pass ByteArray data audio via ExternalInterface function.

My question is, how to play the audio data in storyline in the solution above? Or is there easier solution ?

Encoding ByteArray to MP3/wav file isn't the best solution because of dialog box (FileReference function).

I need to handle audio data in variable in Storyline (or save it as a mp3/wav file without dialog box) because I want to play recorded audio in another slide.
