denver - library to play waveforms (synthesizer included)

[SuperZazu]

Hello,

Here's a new library I made : denver.lua.
That's a little helper to play custom waveforms : it simply generates a sample that you can play with LÖVE.

Basic examples :

Code: Select all

local denver = require 'denver'

-- play a sinus
local sine = denver.get('sinus', 440, 1) -- create a sample of 1sec, at the frequency of 440Hz (note that you can also play square, sawtooth and triangle waves)
love.audio.play(sine)

-- play a note
local square = denver.get('square', 'F#2', 1) -- you can also specify a note : C4, A#2, Fb5
love.audio.play(square)

-- play a looped wave
local saw = denver.get('sawtooth', 440) -- if you want to loop your sound, don't specify a length
saw:setLooping(true)
love.audio.play(saw)

-- play noise
local noise = denver.get('whitenoise', 6) -- 6sec of white noise (you can also use pinknoise and brownnoise)
love.audio.play(noise)


-- bonus : plays a binaural beat (you can use denver.stopBinauralBeat() to stop it)
denver.playBinauralBeat(432, 4, true) -- carrier frequency of 432Hz and a perceived frequency of 4Hz, with pink noise

Cool library, played around with it for some hours. Made a piano/keyboard thing.

Impressive ! :-D

Why would a note stop after a given time ? Why haven't you make it last until the key is released (like in a real piano) ?

The library is really cool !

Well it would be simple to do :-) Here's a simple example.
EDIT: I didn't do it because it wasn't the goal of the library, I just wanted to make things easier when you want to generate some sounds.

Here is something I coded last night before going to bed for android. It was quick because I already have barebones-file for the device.
Today I did some quick tweaking to get it working on pc and used shine lib to make it less ugly.

Its inspired by http://tonematrix.audiotool.com/

it was fun experiment

I really like what you did, it surely is very nice. :-)
