HQtx - high performance conversion of Lx to Tx
(-i item) (-n) file
is a program to obtain excitation periods from a laryngograph signal. It
exploits the characteristic shape of the lx waveform during voiced
excitation. It utilises two derived functions: the sample-by-sample
differential, and the instantaneous gradient. Tx points are extracted
from these functions using an automatic threshold determination procedure.
automatically inverts the lx waveform if it is determined to be upside-down.
This can be cancelled by the "-n" flag.
and their meanings are:
Identify program and exit.
Do not automatically correct for waveform inversion.
Select input item number.
Any excitation item.
High performance tx.
