Abstract
There is provided an audio encoding apparatus that can avoid that audio data becomes irreproducible after fast-forward play. A quantization unit quantizes and buffers audio data into a buffer unit. A stream generating unit puts buffered audio data in a frame where there is a header related to the audio data in a stream and/or in one or plural frames preceding that frame. As for a predetermined frame, the stream generating unit puts in a data field of the frame the whole of an audio data piece related to a header included in that frame and puts audio sample data following that audio sample in a remaining part of the data field. As for a frame not a predetermined one, it puts in a data field of the frame an audio data piece related to a header included in that frame and/or audio data pieces following that audio data piece.
