What is Autotalent?
Autotalent is the result of a week
of recreational signal processing in May 2009. It's a real-time pitch correction
plugin. You specify the notes that a singer is allowed to hit, and
Autotalent makes sure that they do. You can also use Autotalent for
more exotic (Cher / T-Pain) effects. It also can be used as a pitch
shifter or for faux vocal doubling.
Is Autotalent better than X?
Sorry to say I don't know.
I don't own commercial product X, and I don't know how X works. All
of the algorithm development and coding for the current version was
done over a week, so keep in mind that considerably greater resources
are likely devoted to developing corresponding commercial products.
Still, I'd love it if Autotalent were some day a world-class pitch
correction plugin, and I plan to continually make algorithm
improvements.
Can Autotalent be used live?
It works in real-time on my
4-year-old 1.7GHz laptop, so probably. The minimum theoretical
latency of Autotalent at a sampling rate of 48 kHz is 4ms.
Will Autotalent work on my computer?
Autotalent is an
open-source LADSPA plugin and
should in theory work on Linux, Mac or Windows if you compile it for
those platforms, although it has only been tested on 32-bit
Linux.
Things to be improved from ver. 0.1 (5/31/09):
- The
pitch shifter needs an anti-aliasing filter. (Noticable aliasing is
often fairly insignificant as-is. The amount of distortion depends on
the harmonic structure of the source.)
- Right now Autotalent needs a pretty clean (low-noise,
low-distortion) input signal to work well. Future versions will
address this, so you'll be able to auto-tune the
news.
- I'm still waiting on a unique ID from the LADSPA people, and so the
LADSPA unique ID needs to be changed. Right now it's set to 1000.
Where can I get it?
Version 0.1, 32-bit Linux: [tar.gz]
Version 0.1, Source: [tar.gz]
Can I hear it?
Here's a demo. First is a 5 part harmony sung without effects,
followed by a version where Autotalent was used on each track. The
difference is perhaps subtle since the original parts weren't horribly
out of tune, but you'll at least hear an extra coat of studio
sheen.
