1. A sonic conduit tracer system comprising:
an audio transmitter configured to transmit an audio signal down an interior length of an empty conduit from a proximate end of the conduit;
an audio receiver configured to receive an audio return signal at the proximate end of the conduit; and
an audio spectrum analyzer configured to analyze the audio return signal to facilitate the determination of a location of a distant end of the conduit;
wherein the audio transmitter is configured to transmit a first audio transmitted signal having a first spectral bandwidth, a first pulse repetition rate and/or a first pulse frequency characteristic; and configured to transmit a second audio transmitted signal having a second spectral bandwidth, a second pulse repetition rate and/or a second pulse frequency characteristic; and
wherein the sonic conduit tracer system is configured to transmit the first audio transmitted signal when the conduit has a first interior diameter and to transmit the second audio transmitted signal when the conduit has a second interior diameter.
