This audio file offers an example stimulus in which attention is first directed to a lower-frequency band with a higher-frequency distractor band. Listen for the repeat of the 4-tone mini-sequence. The voice directs attention to the lower- versus higher-frequency band in each block. These stimuli were used to measure attention-driven tonotopic mapping of auditory cortex.

Please see the article for a full stimulus description:
