sapf:Sound as Pure Form
|
||||
|
||||
[GitHub - lfnoise/sapf: Sound As Pure Form - a Forth-like language for audio synthesis using lazy lists and APL-like auto-mapping.](https://github.com/lfnoise/sapf)
|
||||
|
||||
[[SuperCollider]]を作った[[James McCartney]]が新しく作っている言語。
|
||||
|
||||
[[Forth]]や[[APL]]から影響を受けた[[逆ポーランド記法]]が特徴的な言語。[[uiua]]とも近いかも。
|
||||
|
||||
|
||||
```sclang
|
||||
15 .0 sinosc 200 * 300 + .0 sinosc .1 * play
|
||||
```
|
||||
|
||||
記法をシンプル(人による)にしたけど内容としてはUGenのメタ操作にかなり向いており、SCに近いと思う。言語としては動的型付けで、配列に関数を自動展開する機能とかがSCのパターン操作とかと同じ感じでよくできてる&存外VMの実装もシンプルそう。
