ABSTRACT:
An audio playback time estimating apparatus and method. The apparatus includes a sampling unit to sample a plurality of sample frames of audio data from audio data including an ID3 tag and a plurality of frames using a quasi-random sampling method, an average-bit-rate-calculation unit to calculate an average bit rate of the audio data based on bit rates obtained from the plurality of sample frames, and a playback-time-calculation unit to estimate the playback time of the audio data based on the average bit rate.
