Data compression? Or Audio compression?
With a Yamaha Motif, they had only so much space for waveform ROM with the computer parts the used to build the machine. To get all the data in the memory, they used data compression.
Audio compression can get more “punch” from the audio... or prevent it from distorting.
Very good question, i asume they mean audio compression simds that ofen is added at the end of the chain... and he is talking about the output...
Data compression comes in two sorts, non losless compression like we know from the mp3’s.. but there is also aiff which is lossless compression and is exactly the same quallity as uncompressed audio...
The question however needs clarification...
