1. A tangible non-transitory computer-readable medium comprising instructions that, when executed, cause one or more processors to perform a set of operations comprising:
identifying a signal bandwidth of a received first audio signal that is obtained from a second audio signal by:
(i) identifying a plurality of indices representing cutoff frequencies of a plurality of time intervals of the received first audio signal; and
(ii) determining a median of the plurality of indices, wherein the median represents an overall cutoff frequency of the received first audio signal, wherein the signal bandwidth is based on the median; and
identifying a source of the second audio signal based on the identified signal bandwidth.
