SWF uses MP3 compression, which stores it's data into blocks of 1152
samples each.
As the number of samples in av3d_loop10.wav is not a multiple of 1152,
the data is padded with 540 zero bytes of silence- I believe the "pop"
you hear is due to that padding.
You could try to convert the WAV file so that the number of samples
is a multiple of 1152- maybe sox or similar utilities are able to do
