32-bit floats can go down around 1e-38 in magnitude before going 
denormal (about -750dB from peak). A least-significant bit of a 24-bit 
integer is about 5e-8 (roughly -144dB). I use 1e-15 (roughly -300dB) 
because it lies comfortably between the denormal rock and the 24-bit DAC 
hard place. 300dB down from peak, I believe, won't ever be audible 
(someone compared it to the magnitude of atomic vibration -- I don't 
know if that's accurate).

I use a relatively low frequency square wave (flipping the bit once per 
process() call) because that has both low freq and high freq content in 
the signal. A highpass filter will tend to turn it into a pulse wave, a 
lowpass will tend to turn it into a sine wave, and either way it gets 
through - so you can inject it once and run it through a bunch of 
filters and reverbs with little fear of it getting wiped out - you have 
to flatten it 400dB more before it even starts to think about going 
denormal, and it's broadband, so just lowpasses or just highpasses 
aren't gonna do it.

That depends how loud you set your amplifier connected to the 32bit
floating-point DAC (you need one that goes to eleven). I'm pretty sure
that the band "Disaster Area" could make it audible in one of their
concerts.

Hotblack Desiato ain't gonna like it.

I'm sorry, this (original) post isn't mine, it's from KVR forum, written 
by someone else. I did send it from my work account to my home account, 
and suprisingly my email client did post it to comp.dsp (or I clicked 
something wrong :-[).

PS. Is "Disaster Area" new band of "Spinal Top" guitarist ?

...and the question that dwarfs all others is: What is the
connection between "a rock and a hard place" and Stonehenge?

Soory. My imagination just clammed up.

Nice pun with the dwarves :-)!

Oops.

Close :-). Actually, Hotblack Desiato is the guitarist of Disaster Area
(but I'm sure he's also got one that goes to eleven). This is the band
that is banned from most planets in our galaxy because their PA
violates local disarmaments agreements.

Thanks.

Do you know if there are more than one Spinal Tap movie?
A couple of years ago, there was a video running on the
cable networks where the line "I know, for I told me so"
appeared. I didn't find it on the "Tis is Spinal Tap" DVD.

Rune

There is the sequel "A Spinal Tap Reunion" (1992) which I haven't seen,
 a number of new short movies (20 - 25mins), plus some music videos.
Have a look in the internet movie database (http://www.imdb.com) under
"Spinal Tap".

I went to see the Hitchhiker's Guide movie a couple of days ago (which
inspired my reply to Habib). Too much romance, too little zest.

Andor

Is it worth going to the cinema, compared to the old BBC series?

Best regards,

If you like the radio plays, or the books, or the BBC TV series, avoid 
the movie. Its awful. It follows the general story line of the other 
versions, reasonably changed to make it a 1.5 hour move. However, it 
omits all the jokes and social commentary that made the original 
interesting. Its like a hollow shell.
