#X text 127 631 A reference file can be created from the content of
\$0-signal-under-test \, using a Pd which is known to work well (the
latest release). Use button 'write'. The file will have 512 samples
in 32 bit .wav format. Even though the test output is not a signal
\, this is a good format to write.;
#X text 130 203 Use a bang from one of [unit-test-frame.pd] outlets
to trigger the object(s) when the test starts. Or use the index 0 -
511 outlet to generate a series of output values.;
#X text 131 255 Normalization of the object output (within interval
0 to 1 or -1 to 1) is useful. It gives a good graph and a meaningful
stddev. Also note that large numbers are unprecise. Example: the difference
between 1e+12 in single precision and 1e+12 in double precision is
27968! Try this on:;

only vanilla Pd classes. For testing external classes \, consider using
namespaces like in [zexy/wrap].;
