With frequent changes in the topics of discussion or other interruptions, sometimes it is difficult to resume a previous thread in a conversation, even if it occurred only minutes ago. The challenge in recalling salient points to trigger memory recall can be avoided if we can just simply re-listen  to parts of the conversation. The Personal Audio Loop (PAL) application is a near-term audio recording system to support the recovery of interrupted conversations. The interface allows a user to specify a time-point in the last 15 minutes at which to begin review.
