The act of pinging is an act of reconnaissance - to ping being a function of the sign, where the sign acts as signal. As all signs are capable of pinging - of bringing back, reconnoitering, the echoes of some other stutter back into their own fold - all signs are capable of being offset, all lack a signpost.
And so all signs are stutters. All stutters are in the process of the ping.
The reconnaissance is an exchange of information - the doorframe communicates some amount of information to the voice and the voice returns a comparable amount of information to the doorframe. So while the process of the ping can be thought of as an offsetting process - a process that allows the stutter to operate as stutter and to be so among a chorus of stutters - the process of the ping can also be thought of as an informing process, that which gives shape to the stutter as a stutter gives shape to the surrounding stutters. The shape of the voice is informed by the doorframe as the voice leaves something of its shape on the doorframe.
Or, in order to be intelligible as a ping, there must exist a narative of its end. That, although the ping will continue to ping so long as there are stutters to ping towards and against, a narative of its ending in a ripple - following the rising, the falling - must be told so as to understand it as a ping. Just is the case with the apple tree - a telos for the apple tree must be to produce apples so that it can be spoken of as an apple tree.
Not to be redundant, but the ping must be encased in a narative of pinging so to be spoken of as a ping.
