Hmm ... actually I got carried away. I can't implement [cos~] or [env~]
with native web audio API nodes.
I'll have to use a slow ScriptProcessorNode. So if performance is not a
concern for you I'll do it, but I won't integrate it to the core of WebPd.

Here's to hoping for Audio Worker Nodes aye :(
Out of curiosity how are the native nodes different from using the
ScriptProcessorNode? For something simple like abs~ or wrap~ is
performance *that
*drastically worse?

Thanks for having a go.
While absolutely agreeing with IOhannes, is it the same situation with
[abs~] and [wrap~]?

Alright! I've added [until], [cos], [sin], [tan], [atan], [log], [exp],

Hi Seb (and Chris!),
Implementation of classes is a bit beyond me atm (willing to learn though:).
If there's a walkthrough I'd be happy to get involved, though I'm aware it
would take more time to set up a tutorial than to just implement them.
Always happy to help with testing if that's helpful.
Yay! Mad skills[z]:)
Cheers Seb

I don't doubt Alexandre's ears or thoroughness but in this instance,when
replacing [cos~] with [osc~] there's a big difference in the sound.
Alexandros - thanks for the sketch, yes it does make sense,
can you send me the patch so I can hear the difference?
there's no argument, but you can use loadbang with a message...

Hey Seb,
Good to hear from you...
Does [osc~] take arguments? In my test when I gave the patch an [osc~ 0] I
got an error in the console saying '0' not understood and I presumed that
was my argument being spat back.
I can't really explain why it doesn't sound right to be honest, this is why

Jonathan's right,
In Pd (vanilla 0.46-4 at least) both [cos~] and [osc~] use the same cos
lookup table. Only [osc~] is a signal generator, and [cos~] the raw
'lookup'. Therefore there shouldn't be any difference between [phasor~] -
[cos~] and [osc~] if the phase is equal.

Hi Julian,
I've attached an optimised implementation for [cos~] that we've been using
for Heavy. It's an approximate taylor series expansion but it should be
much faster than just using cosf(). Hopefully webpd supports [abs~] and
[wrap~].
Cheers,
Joe

Oh right! Makes sense ...
I believe [cos~] and [abs~] could both be implemented by using Web Audio
API's WaveShaperNode. The closest example is [clip~] implementation which
you can find here :

You could also implement cos~ in WebPd and submit a PR to seb. Here are

you can treat [osc~] as [cos~]
just give it a frequency of 0 and use the phase inlet as the angle input
(from 0 to 1).

But the phase inlet of [osc~] is a control inlet, and [cos~] takes
signals..
