Latency
Due to the nature of how Auto-Tune works, along with dierences in
the various hosts, who all add their own bit of latency during tracking,
it’s impossible to state an absolute Auto-Tune Live latency specification.
However, in our tests of Auto-Tune Live in major hosts, latency was
consistently undetectable when tracking live with vocals.
For the technically curious, the maximum inherent latency of Auto-Tune
Live itself, distinct from any contribution by the host, is variable with the
frequency of the audio being detected and range of the correction. As an
example, when correcting to a target pitch of A 440Hz, Auto-Tune Live’s
latency can vary from a only a few samples to a maximum of around 100
samples (less than 2.3ms). Again, this is separate from the inherent latency
of your host.
For all practical purposes, Auto-Tune Live’s response is instantaneous.
However, if you’re the sort who wants to know that you’re getting the
absolute minimum total latency from Auto-Tune Live and your host, you
can reduce your host’s hardware buer size to the smallest size that still
results in acceptable audio performance.
