this is a set of hacked-together hacks to be hacked on
in the personal interest of learning and experimenting.
MIT-licensed; go wild.

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?
2015-06-06 19:41:23 -07:00
crap Constant Equalizer | crap\_eq\_const | `0x0DEFACED` | simpler code than crap\_eq for a static response. edit code as needed.

## build notes
2015-12-10 07:25:23 -08:00
### dependencies
crap is now dependent on [the Eigen header library.][eigen]
for your convenience, a `get_eigen` bash script is provided.
this script simply downloads and extracts the Eigen header files
required to build crap.
[eigen]: http://eigen.tuxfamily.org/

### 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and odds are that your version is horribly outdated anyway.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.
2015-12-05 00:32:51 -08:00
If you really have to use g++,
you may need to add `-fabi-version=6` to CXXFLAGS.
2015-06-07 18:05:49 -07:00
### general building
2014-02-07 17:49:50 -08:00
`make linux` or `make windows` (works well with [mxe])
[mxe]: //mxe.cc
2013-12-22 16:18:37 -08:00
2014-02-24 16:18:58 -08:00
`make linux-arm` requires a CPU with a NEON unit
2014-02-01 17:31:59 -08:00
remember to export `VST_SDK_DIR` to the path of your `vstsdk2.4/`

2014-02-07 17:49:50 -08:00
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
2015-06-04 09:58:15 -07:00
* LV2 support
* automatically generate markdown table based on crap contents
2013-11-17 22:55:09 -08:00
* rename plugins (fix capitalization consistency and such)
2015-12-10 07:25:23 -08:00
* fix code style; particularily braces in method definitions and spaces in casts
2015-06-04 09:58:15 -07:00
* scrap overly-complex makefile for a shell script
2015-06-07 13:18:59 -07:00
* don't mix CamelCase with underscores (only done for legacy reasons)
