audio only swf - frame rate?

using squeeze 4 on a mac, starting with an .aif

does anyone know what frame rate an audio-only swf will be?

is there any way to check the frame rate of a swf?

Thanks Ben

I understand that an audio file as such does not have a frame rate.

but swfs do....? even audio only ones?

Is there a way to specify the frame rate of the swf output file without including video?

it appears that when I encode an audio only file (or switch off video encoding on a a+v mov) the resulting swf has a much higher frame rate.

I do have flash mx - not 2004 - how do I determine the frame rate of an imported swf? It seems that when I import a swf it adopts the frame rate of the scene it is imported into...or am I missing something?

I can probably get round the problem by including a very small black video track with the audio and then hiding the video but its a bit messy.

FYI - I am trying to include an alternate audio track with a swf video player so that I can toggle on and off a "directors commentary" on my web videos.
