What kind of track circuit is audio frequency? It’s a type of AC track circuit in which audio frequency signals are used instead of pure AC or DC signals. Its generally a joint less track circuit, extremity of the tracks are defined by tuned units but can also be used with IRJs. it is least prune to interference and hence can be used in ac, dc, and non electrified areas.

• The Audio Frequency Track Circuit (AFTC) is the Jointless type of track circuit • specifically designed to meet the onerous immunity required in AC or DC electrified areas • against the high levels of interference present mainly due to traction harmonics.
Track Circuit - rail system
https://railsystem.net/track-circuit/
Track circuits work by running a circuit using the rails to connect a power source at one end of the block with a relay at the far end. The relay and power source are connected to each rail by cables. As long as the circuit is complete, low voltage power flows down one rail, through a relay, and returns to the power source via the other rail.

The audio spectrum is the audible frequency range at which humans can hear and spans from 20 Hz to 20,000 Hz. The audio spectrum range spans from 20 Hz to 20,000 Hz and can be effectively broken down into seven different frequency bands, with each band having a different impact on the total sound. The seven frequency bands are: Sub-bass Bass
