Probs with fadew?

[Simon Linke]

Hi Jerome and crew - to run some simulations I'm 'remixing' some soundscapes.

I have issues with fadew (or maybe I don't fully understand it).

I have 3 segments -start, crossover and end.

start is created by cutw(wav)

end is also created by cutw(wav2)

mid is created by fadew(wav1)

Now the curious bit is that the the cutw stay integers

while the fadew outputs are some floating point number between -1 and 1

So when I now do pastew(start.left, mid.left) there's obviously a big block of silence. 

Any clue how I can the fadew into the same integer wave format?

Hi Simon,

This is because fadew() scale first the input by its maximum so that the fade effects can be applied. It could have been better, I admit.

A solution could be to multiply the ouput of fadew() by the maximum of its input, that is:

mid.left <- max(wav1)*fade(wav1)

So with tico:

midleft <- max(tico@left)*fadew(tico, din=0.1, dout=0.1, out="Wave")

Does that work?

Best

Jerome

Haha, I totally forgot I posted that. I'll try tomorrow. Thanks Jerome :)
