1059		log energy
1683		Cube root
5091		energy

Log energy plus:

2093		acf[1] / acf[0]
2049		acf[1] / acf[0] + acf[2] / acf[0]

1436		cep[1]
1907		cep[1] + cep[2]

Add deletas:

1065		cep[0]
2189		cep[0-1]

Just for a laugh - order 10 is:

2380		order 10

so straight log energy is best.

Now look at hte effect of changing windowsize

1059.76		512
1041.43		1024
1041.8		2048

Not worth it.

Now have a VQFF

1068.24		0.5
1059.76		1.0
1022.02		2.0
1050.49		4.0

Start is + 119 samples, end is + 520 samples

There is a consistant delay of 200 samples - check end code.
