Place theory claims pitch is encoded by basilar membrane position

Evidence

Two distinct models have been proposed to explain the perception of pitch: the place model and the temporal model. These two codes likely work in concert to produce the perception of pitch. For pure tones, the temporal model is likely the strongest for lowfrequency sounds and the place model for high-frequency sounds. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1338 (#expands, via linked claim)
