# bobbi-lisp-audio

Audio engine for [bobbi-lisp](https://codeberg.org/bobbicodes/bobbi-lisp) based on the Web Audio API

## API

`playSong` -> (notes, tempo)

### `notes`

`notes` is a vector of maps which must have the following keys:

`instrument`: The audio sample file to be played.

`pitch`: A midi number, an integer representing the frequency. Middle C is 60.

`time`: The beat number at which the note is to occur.

### `tempo`

Tempo is an integer representing the number of beats per minute.

## Example

This would play a major scale:

```clojure
[{:instrument "1.mp3" :pitch 60 :time 0}
 {:instrument "1.mp3" :pitch 62 :time 1}
 {:instrument "1.mp3" :pitch 64 :time 2}
 {:instrument "1.mp3" :pitch 65 :time 3}
 {:instrument "1.mp3" :pitch 67 :time 4}
 {:instrument "1.mp3" :pitch 69 :time 5}
 {:instrument "1.mp3" :pitch 71 :time 6}
 {:instrument "1.mp3" :pitch 72 :time 7}]
```

Of course it would be very tedious to write music that way. Fortunately we have all the power of function composition to generate them. See [demo.clj](https://codeberg.org/bobbicodes/bobbi-lisp-audio/src/branch/main/demo.clj) for a complete arrangement, and [SimLispy](https://codeberg.org/bobbicodes/SimLispy) for an example of how to use it in your project.
