| Frame count
| Framecount
| Sound effect usage. Each byte represents a frame, and bit #1 represents Sound effect 1, bit #2 represents Sound effect 2 and bit #3 represents Sound effect 3.
| Sound effect usage.
| Each byte represents a frame. bit #1(from Right to Left) represents Sound effect 1, bit #2 represents Sound effect 2 and bit #3 represents Sound effect 3. the last 5 bits is padding.

| Frame speed. To get the correct value, you must take 8, and subtract the decimal value of this byte.
| Given 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.

| Unknown - Used for sound decoding? (samplerate, compression, etc)
| Current 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.

I have yet to figure out the sound decoding...--[[User:Pbsds|pbsds]] 17:38, 6 June 2010 (UTC)
Then comes the audio data.
*First comes the BGM(if used)
*Then comes sound effect #1(if used)
*Then comes sound effect #2(if used)
*Then comes sound effect #3(if used)
To decode the sound data, you must multiply each byte by 16 and run it as 32000Hz PCM data.
