摘要： An audio signal recording and reproducing apparatus can perform realtime processing with a structure having a low cost. The audio signal recording and reproducing apparatus records a series of input audio signals as digital audio data, and reproduces and outputs the input signals using the recorded digital audio data as output audio signals. An input audio signal processing unit converts the series of input audio signals into digital audio data. A data file recording unit records the digital audio data, as digital audio data file information, on a recording medium, the recording medium having a plurality of clusters in which data having a predetermined number of bytes is recorded, the digital audio file information being recorded over a plurality of clusters. A file management information recording unit records on the recording medium file management information representing the reproducing order of the clusters in which the digital audio data file information is recorded. A directory information recording unit records on the recording medium directory information including at least the number of the first cluster recorded first when the digital audio data is recorded. A reproduction procedure file information recording unit records on the recording medium the reproduction procedure file information including at least the number of the first cluster of a digital audio data file to be reproduced. An output audio signal processing unit converts digital audio data, which is read out from the recording medium in accordance with the reproduction procedure file information, into output audio signals.
