This specification describes technologies relating to reducing audio masking. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of receiving a primary audio signal and a secondary audio signal; for each audio signal, calculating an average perceived intensity over time for each of a plurality of frequency bands; comparing the average perceived intensity of the secondary audio signal with the average perceived intensity of the primary audio signal for each frequency band; and for each frequency band where the average perceived intensity of the secondary audio signal is greater than the average perceived intensity of the primary audio signal by a specified threshold amount, attenuating the secondary audio signal by a specified amount to form a modified secondary audio signal. |
