hello list.
how can i read the cue-list in a Wave File?

i think, there was a post before on this subject:
bret said something like:
“interesting, yeah i was going to add some functionality for the sync callback stuff.. i was going to add ways to add and delete your own callback points, so i guess being able to list them would be useful as well.”

i think, i could just read the RIFF Format of the Wave File:

RIFF ‘WAVE’ (wave file)
<fmt > (format description)
PCM format
1 channel
11025 frames per sec
11025 bytes per sec
1 bytes per frame
8 bits per sample
<data> (waveform data – 52862 bytes)
<cue > (cue points)
#1: sample 23168 (playlist position 23168)
#2: sample 30976 (playlist position 30976)
#3: sample 35520 (playlist position 35520)
#4: sample 38816 (playlist position 38816)
#5: sample 42400 (playlist position 42400)
#6: sample 44976 (playlist position 44976)
#7: sample 48960 (playlist position 48960)

like in the RiffViewer app from:
http://www.mda-vst.com/bin/riffview.zip

but after reading infos in the net and as a slow-brain i don’t get it right.

maybe someone is also interested on this topic and there are some solutions.

thanks

hello.
o.k. , i know the FSOUND_Stream_SetSynchCallback, and i’m using it
like in the “fmod” eyample code. great example, by the way. ๐Ÿ˜€

my idea was:
when i edit the samples in cooledit i can save markers within the wave file.
i thought it would be nice, when i read the wave in fmod, i could read the <plst> Riff chunk where the <playlist> information of the markers is stored.
then i could reach every marker directly, because i have the cue-informations when i load the file.
i could jump within the sample from marker to marker and do some
weird sound stuff. ๐Ÿ˜ฎ

thats more an idea for a music aplication than for syncronising some openGL engine to the sound. or something like that. :roll:
i thought it would be nice when you have access to the RIFF information
of the wave file.
more like a wave file analysis.

hello list.
well, i worked on the getting-the-cue-list-problem the last days.
i have a very ugly solution on my machine, but it works !!! ๐Ÿ˜‰
i use the <mmsystem.h> functions to read the IFF chunks.
(you don’t have to use fmod for this ๐Ÿ˜‰ )

ruffly, that means:
mmioOpen // open the file
mmioFOURCC /*
the Four-Charakter-Code for the chunk, you want to search for:
1. ‘W’,’A’,’V’,’E’ // the header
2. ‘f’,’m’,’t’,’ ‘ // some other header ๐Ÿ˜‰
3. ‘d’,’a’,’t’,’a’ // the music
4. ‘c’,’u’,’e’,’ ‘ // the cues
*/
mmioDescend // scan the file for the FOURCC
mmioRead // read the chunk into your struct
mmioAscend // leave the file for the next search
// you have to De,- Ascend for each FOURCC !!!!!!!!!!!!!!
mmioClose // close the file when finished with everything
(maybe i should post some example code here ?) ๐Ÿ˜†

for everybody who is interestet in the WAVE Format for windows.
i recomment to check this out, because
there is everything you’ll need to solve this problem.
http://www.borg.com/~jglatt/tech/miditech.htm
and you get some funny facts ’bout the WAVE format itsself.
so, just “rtfm”, like always.
