crap
connor's rancid audio plugins. LADSPA and VST.
this is a set of hacked-together hacks to be hacked on in the personal interest of learning and experimenting.
MIT-licensed; go wild.
plugs
| Name | Label | ID | Description |
|---|---|---|---|
| crap Parametric Equalizer | crap_eq | 0x000CAFED |
multiband parametric EQ. try redefining BANDS. #define BANDS to desired number of equalizer bands; default 4. |
| crap sample delay test | crap_delay_test | 0xDEDEDEDE |
why did i commit this? |
| crap Constant Equalizer | crap_eq_const | 0x0DEFACED |
simpler code than crap_eq for a static response. edit code as needed. |
| crap T420 Speaker Compensation | crap_eq_const_T420 | 0x0DEFAE91 |
lenovo tests |
| crap T420 Speaker Compensation (SVF) | crap_eq_const_T420_svf | 0x0DEFB3CA |
trying out State Variable Filters (SVFs) |
| crap mugi4 (moog-like) | crap_mugi4 | 0xD8D0D8D0 |
nonlinear moog filter implementation: see reference |
| crap Tube Distortion | crap_tube | 0x50F7BA11 |
static waveshaper with 6x oversampling and parameter smoothing. doesn't actually emulate a tube. not actually for crapping in. |
| crap Leveller | crap_level | 0xAAAAAAAA |
an early prototype of a heavy leveller. |
build notes
dependencies
crap is now dependent on the Eigen header library.
for your convenience, a get_eigen bash script is provided.
this script simply downloads and extracts the Eigen header files
required to build crap.
clang is strongly recommended
gcc can potentially produce significantly slower code, and odds are that your version is horribly outdated anyway.
Debian/Ubuntu users: your stable version of g++ can't even build this.
just apt-get install clang-3.6 and export CXX=clang++-3.6 when building.
If you really have to use g++,
you may need to add -fabi-version=6 to CXXFLAGS.
general building
make linux or make windows (works well with [mxe])
[mxe]: //mxe.cc
make linux-arm requires a CPU with a NEON unit
remember to export VST_SDK_DIR to the path of your vstsdk2.4/
other targets:
- all: no hand-holding.
- design: simple CLI to the biquad coefficient calculator.
- benchmark: does what it says on the tin. no Windows support.
TODO
- LV2 support
- automatically generate markdown table based on crap contents
- rename plugins (fix capitalization consistency and such)
- fix code style; particularily braces in method definitions and spaces in casts
- scrap overly-complex makefile for a shell script
- don't mix CamelCase with underscores (only done for legacy reasons)
