More examples of what we do:

• reduction or removal of acoustic spill-over between tracks in a multi-track recording: suppose you have a live multi-track recording, and the voice is too weak, because too much instrumental sound has entered the vocal mike. By reducing the spill-over, the voice can be boosted more effectively to create a good-sounding mix. This cannot be done with conventional filtering techniques. CSP has it's own new methods.
• removing or changing a wrong note in a chord: suppose your keyboardist struck a chord with a wrong note. We can often take out the note or even change it.
• changing the pan position of an instrument or voice in the mix, stereoizing a mono recording.
• extracting a vocal phrase for use in a re-mix: this is quite difficult, but can be done with very dedicated processing
  (read more here.)
• removing a background noise
• re-mastering an older recording, correcting some mistakes, and improving the overall sound.
• fixing a problem that was considered unfixable before: we look at the problem from our perspective and can often fix it, or achieve an improvement at least.

For want of a better term, we like to call our speciality 'sound surgery': dedicated 'surgical' modifications and corrections, to fix an annoying problem, that otherwise would ruin a perfectly good track. And, just like real surgery, a proper diagnosis beforehand is essential. That's why we need you to describe your problem carefully!

Our 'surgical instruments' are mostly by our own design, allowing us to perform unique operations.
