| Current Framespeed.
| This is the speed of the flipnote. It's in the range of 1-8. To get the correct value, you must take 8, and subtract the decimal value of this byte.

| Current Framespeed when BGM was recorded.
| Given Framespeed when BGM was recorded.
| This is the speed of the flipnote when the BGM was recorded/modified. It's in the range of 1-8. This is used to resample the sound to the new speed. To get the correct value, you must take 8, and subtract the decimal value of this byte.

*Then comes sound effect #3(if used)

The sound data appears to be PCM, 1 channel, 8 bits per sample, at 4096 Hz. When played back with these parameters, the audio is quite audible, BUT there is a lot of background hiss. Perhaps there is a low pass filter on the DSi audio output?
The sound data seems to be a variant of VOX ADPCM @ around 8KHz.
