      It is unsafe to use the same f-variable for both input and output of pvs opcodes. Using the same one might lead to undefined behavior on some opcodes. Use a different one on the left and right sides of the opcode.

     In the example above the filter curve will depend on the
93
88
spectral envelope of afil; in the simple case of a sinusoid,
94
89
it will be equivalent to a narrowband band-pass filter.</para>
