I have trouble understanding how the Sound->lock() function works. At least, I thought I understood it, but reading this forum post confused me again: [url:1jr9kcu3]http://www.fmod.org/forum/viewtopic.php?t=13230[/url:1jr9kcu3] 😀
The example does not work for me — after the lock(), my buffer is always empty.
In particular, in the linked post I don’t know why 0 is passed as the second parameter of lock()! As far as I understand this function, the second parameter says how many bytes to lock in the buffer. So I really don’t see how passing 0 would help you get the waveform for the whole song.
Can anyone please explain how lock() could be used to get the whole waveform? Thanks!

the code you saw in that thread is wrong.
There should be a Sound::getLength call there with FMOD_TIMEUNIT_PCMBYTES as the timeunit, to get how long the sound is in bytes.
(after the lengthbytes declaration, and before the call to lock)
