DSP'ing a CD

Hi folks,

I'm intrigued by the concept of digital room correction using devices like the Tact or Lyngdorf. However no-one in my neck of the woods sells them, so I've never had a chance to hear what they could do for me.

Here's an thought - instead of adding a digital room correction device, could you:

1) use a spl meter (or a sound card & mic) to determine your room's response
2) enter the measurements into software that will calculate the EQ curve that would correct your room's uneven response
3) rip a cd using EAC or similar
4) digitally apply the EQ curve to the wav files
5) burn to CD and play

You should then hear what your room would sound like if you'd used DSP, but without the possibly deleterious effects of adding a DSP device into your rig.

Would this work? Anyone already doing it?

Cheers
Mick
