In reference to the current disscussion about Sound Resouces on the Mac II someone said something about haveing sounds sampled at a different rate and wanting a program to re-sample them to the right sample rate for the Mac II. You DO NOT NEED to do this!!! It only doubles or quadruples the number of samples in the file. The SoundManager in the Mac II will happily re-sample the sound at play time! All you have to do is look in the header of the snd resource (either type 1 or type 2) and change the sample rate constant. The Sample rate constant tells the Sound Manger what sample rate the sound was sampled at. It is a 32 bit fixed-point number (binary point in the middle). For various sample rates the proper values are: 44,100.00hz (CD Rate) AC44 0000 22,254.54hz (Mac Rate) 56EE 8BA2 11,127.27hz (Half Mac) 2B77 45D1 5,563.63hz (Quarter) 15BB A2E9 In any of the system beeps you should find the value for mac or half mac I don't remember what offset the value is stored at, poke in the system ones to see. -Mark Lentczner ATG Graphics & Sound Group Apple Computer, Inc. 20525 Bandley Drive, MS:22Y Cupertino, CA 95014 mark@apple.CSNET {dual,ios,voder,nsc}!apple!mark.UUCP -- -Mark Lentczner ATG Graphics & Sound Group Apple Computer, Inc. 20525 Bandley Drive, MS:22Y Cupertino, CA 95014 mark@apple.CSNET {dual,ios,voder,nsc}!apple!mark.UUCP
