I am not positive I am understanding your need correctly, but you
might want to check out the QSSP audio visualization component from
TotallyHip: <http://www.totallyhip.com/components/qssp/>. For some
examples using it, check out the Cornell Lab of Ornithology Website's
Raven Viewer at <http://www.animalbehaviorarchive.org/
loginPublic.do>. You have to download the player and install the
QSSP pluging and restart your browser (a few hoops to jump through),
but it well worth it.
Hope that helps,
John

Hi All,
I want to draw a wave representation of an m4a or a MP3 file.
I want to draw the wave in few seconds.
The method i am using is taking value of sound from a
callback function during playtime. But it takes the same time as
needed for playing the file.
Is there any other method of reading audio file directly and
get the audio values in seconds.
can i take audio values like this
ExtAudioFileRead( tExtAudioFileRef, &numberOfFrames, &tABL);
if so how can i retreive values from the buffer using an ordinary
for loop till the end of the file?
Thanks in Advance
Sandeep A.C
