12 The Calf project aims at providing a set of high quality open source
13 audio plugins for musicians, possibly in many different plugin formats,
14 so that they can be used in as many hosts as possible and in standalone
15 mode. Currently available plugins:
16 * Flanger with linear interpolation. In case "zipper noise" of
18 basic flanger effects was driving you mad, use this one!
19 * Simple reverb with basic controls and relatively neutral sound.
20 No dreaded metal barrel sound, at expense of higher CPU use and less
21 time density.
22 * Multimode filter (selectable 12dB/24dB/36dB rolloff, lowpass or
23 highpass) with inertia/smoothing for cutoff for more "analog" sound
24 when tweaking.
25 * Vintage delay - in other words, a very simple simulation of tape
26 echo, with a filter in a feedback loop.
27 * Simple monophonic synthesizer with 2 oscillators, multimode fil‐
28 ter and an envelope.
29 * Optional: electric organ synthesizer and rotary speaker emula‐
30 tion, best used together (use "configure --enable-experimental" to
31 enable them) The plugins are available in following formats:
32 * LADSPA (all effect plugins)
34 * DSSI (both synthesizers and effects), including DSSI GUI
35 * Standalone JACK client application with GTK+-based GUI (new: it
36 is possible to run several plugins simultaneously in one JACK client,
37 and connect them in chains using standard JACK facilities)
38 * LV2 (experimental, SVN only, some features may not work, host
39 support for several features may vary)

42 How to use Calf plugins:
43 * LADSPA plugins
46 Calf is installed as calf.so library in your LADSPA directory
48 (typically /usr/lib/ladspa). It means that typical LADSPA host
49 should be able to find Calf's plugins.
50 * DSSI plugins
53 The calf.so module is also installed in your DSSI plugin direc‐
55 tory, which means your DSSI host (like jack-dssi-host or
56 rosegarden) should find it and include its plugins in the plugin
57 list.
58 * JACK client application
61 You can also use Calf plugins as one or more separate applica‐
63 tions, connecting to other applications using JACK Audio Connec‐
64 tion Kit (version 0.103 or newer is required). To run the
65 client, type:
66 calfjackhost monosynth !
68 (! means "connect", last "!" means "connect to output")
70 Other examples:
72 calfjackhost monosynth ! vintagedelay ! flanger !
74 (runs monosynth into vintagedelay and vintagedelay into flanger,
76 then to output)
77 calfjackhost ! reverb !
79 (takes signal from system:capture_1 and _2, puts it through
81 reverb, and then sends to system:playback_1 and _2)

89 LV2 support is in infant stage. Some knobs may still cause clicks/zip‐
90 per noise. Plugin versions (especially LADSPA) have very poor usability
91 comparing to standalone versions, because of platform limitations. In
92 case of other bugs, please send bug reports to <wdev@foltman.com>, they
93 will be fixed in order of importance.
