Hi,

I'm just in the process of adding support for the replay gain fields in the Lame tag to EncSpot.

Does anyone know how the 32 bit floating point 'peak amplitude' value is stored? Maybe I am going crazy, but it does not seem to be in IEEE 754 format. The docs on replay gain say things like 'TODO : say more about floating point format'


Of course I could start digging around in the Lame source code... but if anyone has a quick easy answer/link, it's be really helpful....

cheers,

/* peak sample */
if(gfc->findPeakSample)
nPeakSignalAmplitude = abs((int)((((FLOAT)gfc->PeakSample) / 32767.0 ) * pow(2,23) +.5));
