hi, you have an offline harmonizer in SMSTools [1]
if you want something realtime, by chance recently i was working in
that as part of a google summer of code project[2]
it's a network under CLAM's NetworkEditor[1]
more details (and demos) here: http://audiores.uint8.com.ar/blog/?p=124
regrettably, there still there some artifacts that came from the
pitch-shifting process but i hope that issue could be solved soon
all those changes are now only at the svn version but i think that
will be a new clam release soon
cheers,

Lately I've been eyeballing some fancy $600 harmonizer rack units at
$music_store. (http://www.tc-helicon.com/VoiceWorks, for example) Not
wanting to drop that much cash, I got to looking for some software
effects that can do the same, without any luck.
Does anyone know if such a thing exists? Is it possible, or is it too
CPU intensive? If the latter is true, I was pondering some sort of FPGA
on PCI device for number crunching. I could think of a fun thing or two
to do with it. Has anyone ever done some similar work?

(cp -a /xxx /usb_device && sync) &
But remember sync flushes _everything_.

Does it at all need impulse response convolver as suggested...?
How about just tracking the engine pitch and having
a sampler to do the sound? LinuxSampler for fine details.
The device may be illegal in Europe.

Is this patented? I could not find.
http://www.vroombox.com/vroombox/
I don't know details of them, but I come up
with the idea some years ago --- as to exists as
an open source, free Linux software, naturally.
I even mailed to Blaupunkt and asked if it is ok to
send them suggestions. Because I received no reply,
I did not send anything to them about my invention.

I have invented one of that type too. ;)
The vroombox is not a stupid idea in my opinion.
It is what car customizers and young males might want
in their car. I became aware of vroombox via MTV's
Pimp My Ride show -- check if you catch a possible rerun
this week.

fixed. Every user is encouraged to upgrade.
Please contribute with bug reports and artwork. See
http://www.alsaplayer.org/artwork.php3 for existing artworks.
Discussion about which artwork(s) to include with the next stable release will
be done on the mailing list. See the website for details:

Hi,
For some unknown reason, I seem to be unable to set SND_PCM_FORMAT_FLOAT
format flag when initialising alsa driver. This happens with my both cards
(on is the laptops AC'97 Audio Controller and the other a similar onboard
cart)
This line used to work with alsa 0.9 but return an "Invalid argument" error
with alsa 1.0.14a :
snd_pcm_hw_params_set_format(alsa_pcm_handle, alsa_hwparams,
SND_PCM_FORMAT_FLOAT_LE)
If I remove this line, the driver gets initialised but as integer sample
format, which, of course, generates noise as I'm sending 32bit floats to the
output...
Example code at lines 1031-1041 :
http://cvs.savannah.nongnu.org/viewvc/freecycle/src/soundplayer.cpp?annotat…
Please, please help !
