# beep
[](#contributors-)
Synthesizing raw PCM music using Go from scratch.
## TODO
- [x] Refactor to idiomatic go code
- [x] Rename to a proper name
- [x] Make examples
- [x] Make note durations methods on `beep.Melody` (as they are dependant on the note length and BPM)
- [ ] Implement a simple format - ~~mp3~~ / wav
- [x] Define all notes in all octaves a seperate file
- [ ] ~~GUI + keybinds~~ - Will be a separate project
- [x] Play multiple notes at once (chords)
- `f(x) + g(x)` where `f` and `g` produce different notes, should result in them playing at the same time
- [x] Note -> SingleNote, add Chord (multiple notes). Both implement new Note interface
```go
type Note interface {
Samples(sampleRate float64, generator Generator, adsr ADSR) []float64
}
```
- [x] Support for merging melodies (playing 2 melodies at the same time)
```go
g := beep.NewMelody(...)
g.AddNotes(...)
// or
g.Runs[0].AddNotes(...)
// more runs, i.e. staves
g.NewRun(notes...)
```
- [ ] Support for concatenating melodies / have melodies with differing BPM
```go
g := beep.NewMelody(...)
g.AddNotes(...)
n := beep.NewMelody(...)
n.AddNotes(...)
o := g.Concat(n) // combines both melodies and makes a longer one
```
- [ ] Dual Channel support (left and right ear)
- [x] ~~Fix clipping in release of linear ADSR~~ _(theoretically negligible)_
- [x] Implement logarithmic / exp ADSR
- [x] Support for dotted notes
- [ ] Overtones
- [ ] Fix periods for generators that aren't sin (?)
## How to play music
```console
ffplay megolovania.bin -autoexit -showmode 1 -f f64le -ar 48000
```
