Hi
I'm trying to make a guitar tuner ladspa plugin.
I already wrote a first draft, but listplugins can't find my plugin in
the library :
$ listplugins
...
/usr/lib/ladspa/TunerUnit.so: <---
/usr/lib/ladspa/tap_doubler.so:
...
it could be because I've chosen a uniqueID already in use.
is there a list or way to register a uniqueID ?
here is a part of my _init() function:
g_psTUDescriptor->UniqueID
= 4053;
g_psTUDescriptor->Label
= strdup("tner");
g_psTUDescriptor->Properties
= LADSPA_PROPERTY_HARD_RT_CAPABLE;
g_psTUDescriptor->Name
= strdup("Universal Digital Tuner Unit");
g_psTUDescriptor->Maker
= strdup("Rémi Thébault");
g_psTUDescriptor->Copyright
= strdup("None");
By the way, for the moment I use FFTW for the frequency identification.
Is there a way to identify a frequency with quite high precision without
computing a big spectrum analysis ?
For a 0.7 Hz precision with fft, I need 65536 samples, what will take a
lot CPU load every 1.5 sec.
It is obvious that so much CPU Load is no acceptable for a small plugin
in a realtime application.
Rémi
