PROBLEM TO BE SOLVED: To provide an anomaly monitoring apparatus capable of lengthening the time required to extract audio data, which is to be transferred from a signal processing part to a CODEC, from the signal processing part and reducing the processing load of the signal processing part. SOLUTION: The CODEC 11 converts analog signals output from a vibration sensor 2 into audio data, which is serial data in audio data format. When audio data is input, the CODEC 11 converts the audio data into analog signals. The signal processing part 10 transmits and receives audio data with the CODEC 11 and determines the presence or absence of anomalies of an apparatus 3 through the use of audio data input from the CODEC 11. A control circuit 13 is inserted in a transfer path of audio data from the signal processing part 10 to the CODEC 11. The control circuit 13 has a buffer and transfers audio data, which is to be transferred from the signal processing part 10 to the CODEC 11, at a timing specified by the CODEC 11 after the audio data is captured in the buffer.
