#X text 97 22 16bit-table;
#X text 32 51 [table16] stores 16bit values. The normal pd-tables ([table]
, array) store the values as floating-points. While floating points
are (often) more precise (this is of course not really true... , esp.
when comparing integer(4byte) to floating-point.) they use a lot of
memory (4byte).;
#X text 32 121 [table16] uses only 16bit (2bytes) to store the values
, which is half of the memory.;
#X text 32 155 However there are 2 major drawbacks;
#X text 53 172 a) less precision means less SNR - you can only store
65536 different values , but this is what CD-quality is (should be
good enough for most musical applications);
#X text 55 221 b) the 65536 values (-32678..+32767) are mapped to -1.0..+1.0!
This means you cannot store signals that exceed this magical limit.
Please make sure , that the signal has correct values (use [clip~])
or the unclipped values will get wrapped!;

#X text 19 410 The message-objects [tab16read]/[tab16write] store the
values directly (-32767..+32768) , while the signal-objects convert
the floats -1.0..+1.0 to the correct values or vice-versa.;
