	If you record at 20K/sec, then you are recording at
20K/sec no matter how simple or complicated. As to recording (I
assume you have a HD if you are doing this kind of stuff) look
into AGMSPlaySound and AGMSRecordSound which allow digitizing to
disk and playing from disk so that RAM isn't a problem. Playing
back can go full-speed with a HD, but recording has its limits.
On a 68000 you may be limited to under 10K/sec.
	I have an A3000 and had a hard time recording at any
decent speed so I used AudioMaster to record the sound, and when
I ran out of memory I pressed pause on the CD player, saved it,
and started recording anew and then started the CD again.
