1/3 Octave filters meeting IEC 1260 Class 1

Does anyone have a Windows program that operates on a 16 bit .wav file - that produces filtered versions of the original?

In particular, I'm looking for a bank of 1/3 octave filters with centre frequencies of the usual ISO points:
- 100
- 125
- 160
- 200
- 250
- 315
- 400
- 500
- 630
- 800
- 1000
- 1250
- 1600
- 2000
- 2500
- 3150
- 4000
- 5000

Also, the slopes and passband ripple need to meet IEC 1260 for the class 1 filters. Thanks!
