I decided to have a look at this again as I see the problem still hasn’t been fixed with the latest release.
Anyway to everyone who’s having the problem (I notived there’s a lot of posts regarding it), it can be "solved" by simply increasing the amount of buffers used (the number depends on the files) however obviously that’s not a perfect solution.
Actually the realtimestitching example method hasn’t worked.
It’s fine for the files included however if I replace them with my own mp3 it seems to "swap" at the wrong time.
Could this be with how the FMOD_TIMEUNIT_BUFFERED flag is used, do I need to use a different flag or comibantion perhaps?
I also don’t think I can use the accurate_sequencing example as it swaps channels and I think the wiki says that’s not possible with hardware decoding as only one channel can exist at once. I am on iPhone.
Plus stitching should really work so I think it must be something simple.
Hi Fmod guys,
We’re trying to get our game out the door and really need this sorted. I’m sure someone has needed to do this with mp3s.
Is there not a solution?
btw – It’s not a bug in my code as I’ve tested it using the sample by replacing where the songs are defined so it now becomes:
"../media/floating_in_the_atmosphere_intro.mp3", /* Ma- /
"../media/floating_in_the_atmosphere_middle_1.mp3", / ry /
"../media/floating_in_the_atmosphere_middle_2.mp3", / had /
"../media/floating_in_the_atmosphere_middle_1.mp3", / a /
"../media/floating_in_the_atmosphere_middle_2.mp3", / lit- */
And I’ve also verified that my mp3s’ format is PCM 16 with two channels and sampled at 44100Hz.
I tried even taking this info from the mp3s using GetFormat.
I also tried to get it working by using 3 sub sounds sentence instead of two.
At the moment I’ve put in a timer to stop it changing within a couple of seconds and that helps it a little however it’s no solution.
You are right, on iPhone the sequencer wont work with the hardware decoder. I’m not entirely clear what the issue is

How far off is it? A few samples like a ‘pop’ sound? A few miliseconds like a tiny gap or glitch, or many miliseconds?
I think it could possibly related to inaccuracy of MP3 encoding, as an experiment can you try using a different format like PCM or ADPCM and see if that exhibits the same issues.
