Revision 3612 - (view) (download) (annotate) - [select for diffs]
Modified Mon Sep 30 18:03:43 2019 UTC (4 years, 5 months ago) by schoenebeck
File length: 11670 byte(s)
Diff to previous 3561
Added new LFO implementations:

* Added int math square LFO implementation.

* Added int math saw LFO implementation.

* Added numeric complex nr sine LFO implementation.

* Added public API C++ class "LFO", which is a cluster class
  encapsulating all the sampler's LFO implementations to be used by
  3rd party applications (e.g. by Gigedit).

* Marked class LFOTriangleDiHarmonic as deprecated
  (will be removed in future).

* Added LFOAll.h which includes all LFO implementation's header files.

* Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
  algorithm (since result of 2nd run was not accumulated).

* Added benchmark for saw wave (benchmarks/saw.cpp).

* Added benchmark for sine wave (benchmarks/sine.cpp).

* Added benchmark for square wave (benchmarks/square.cpp).

* Increased amount of benchmarks runs by factor 6 to achieve benchmark
  times which are large enough on modern systems.

* Cleanup of LFO APIs.

* Bumped version (2.1.1.svn18).

NKSP: Added standard units support for numbers and final "!" operator:

* NKSP strictness: Variable names, function names and preprocessor condition
  names must start with a regular character (a-z or A-Z); starting them with
  a digit or underscore is no longer allowed.

* NKSP parser fix: equal comparison operator "=" and not equal comparison
  operator "#" must only accept integer operands.

* NKSP language: Implemented support for standard units like Hertz, seconds,
  Bel including support for metric unit prefixes; so one can now e.g.
  conveniently use numbers in scripts like "5us" meaning "5 microseconds",
  or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
  "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).

* NKSP language: Introduced "final" operator "!" which is specifically
  intended for synthesis parameter values to denote that the synthesis
  parameter value is intended to be the "final" value for that synthesis
  parameter that should explicitly be used by the engine and thus causing
  the sampler engine to ignore all other modulation sources for the same
  synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
  variable or formula with this new "!" operator the expression is marked as
  being "final".

* Bumped version (2.1.1.svn4).
