All these machines can play back sound without additional hardware,

! NeXT and SGI come with standard sampling hardware (the NeXT only
! samples U-LAW at 8000 samples/sec from the built-in microphone port;
! you need a separate board for other rates). (Don't send me details on
optional or 3rd party hardware, there is too much and it is really

! The MOD sampling rate
! ---------------------
!
! From dgc3@midway.uchicago.edu:
!
! The standard rate is 10k exactly. Instrument files should be 10k,
! signed, 8-bit raw audio. A lot of people ask how to create MOD
! samples on their own machine; the answer is:
!
! [%>] sox mysound.foo -r10000 -sb sample.sam
!
! I quite doubt that there are any deviations here, since the sample
! data is incorporated into the MOD file and cannot store its own format
! header. The Amiga program MED uses a custom format for its MODs
! (often called MEDs because of name similarity), and does allow any
! 8SVX sample of any sampling rate to be used.
