f0 frequency difference limen
Dear Andrew,
In our 2001 paper on the pitch of unresolved harmonics we used high-pass
filtered low-pass masked click sequences. As a control we tested also
low cut frequencies and/or stimuli without low-pass masker (which would
allow to make use of distortion products). Click sequences can be seen
as complex tones with all possible harmonics. They contain both resolved
and unresolved harmonics (as long as one does not remove them, as we did
in some conditions).
The limit for low cut frequencies and/or absence of masker (i.e. for the
best availability of both resolved and unresolved harmonics) was at a
2AFC DL of about 0.5%.

Subject: f0 frequency difference limen
Dear members of the list,
Is there a consensus on the size of the frequency difference limen for the f0 of complex tones such as those
produced by musical instruments - i.e. containing both resolved and unresolved harmonics. References to papers
describing the precise nature of the tests used would also be helpful.
Many thanks
Andrew Milne
