# A plugin profile — machine-readable facts about Quefrency.
#
# Host this next to your plugin as profile.ttl and it can be read by this
# catalogue and by anything else that speaks RDF. It is yours: edit it, version
# it with the plugin, and it stays correct because you control it.
#
# The subject below is the plugin's homepage, which is what identifies it here.
# If you would rather use your own namespace, change that one IRI and keep the
# foaf:homepage line, so the two can still be joined up.

Latency is 2047 frames at 50 kHz and below, 4095 above, and is reported to the host." ;

    trn:caution "Transients smear when pitch or frequency shift is set, as with any phase vocoder. Lifter must sit below the shortest pitch period or harmonics leak into the envelope. A controller's value is not shown on the panel and is not saved; it holds until the host's own value for that parameter next changes." .
