" Remember, Nyquist sampling<br>theorum states that your sampling frequency must be 2x the max. frequency.<br>So at 44.1, you're recording up to 22kHz. Go much lower and you cut off part<br>of the audible range."
<br><br>ah hah.. this sentence is very interesting + something I've not heard before. <br><br>i once had someone explain to me that our 'audible' range is a bit of a misnomer - simply because our brains are so good at guessing the fundamental based on the harmonics - so a speaker that cant reproduce a bass fundamental (unless its 15inch) will still sound okay because of reconstruction in our brains. however seeing as I've not done any actual research on it myself, could be completely on the wrong track!

</blockquote><div><br><br>64 bit 22k it is! :)<br><br>so dynamic headroom is also going to be a factor here.. hmm. <br><br>i need to find that balance between performance and what sounds 'okay'. i also dont like the idea of sounding 'like a CD'. I'm not sure if anyones ears are strong enough to pick up on that, but there seems to be a 'smoothness' to CDs which I find irritating when someone is meant to be playing live.
<br><br>thanks for all the advice<br></div><br></div><br>
