The present invention relates to a record carrier (D) storing audio data as audio tracks (t) in audio files and associated management information (m). Further, the present invention relates to a corresponding playback and recording apparatus. To avoid annoying clicks at the end or beginning of live recorded audio tracks if those tracks are not played back seamlessly but by suppressing of introductory audio data stored in the pre-track, it is proposed according to the present invention that a seamless playback information (play_pre_track) is provided in the management information (m) indicating if an audio track (t) has to be plaid back seamlessly after a particular other audio track.
Record carrier comprising audio data (A) as audio tracks (t) in audio files and associated management information (m), said management information (m) comprising seamless playback information (play_pre_track) indicating if an audio track (t) has to be played back seamlessly after a particular other audio track.
Recording apparatus for recording audio data (A) as audio tracks (t) in audio files and associated management information (m) on a record carrier (D), comprising audio recording means (11) for recording an audio track (t) and said management information (m) on the record carrier (D), the apparatus further comprising management information update means (12) for updating said management information (m) by including seamless playback information (play_pre_track) indicating if the audio track (t) has to be played back seamlessly after a particular other audio track.
Method of recording audio data (A) as audio tracks (t) in audio files and associated management information (m) on a record carrier (D), wherein said management information (m) is updated when an audio track (t) is recorded on the record carrier (D) by including a seamless playback information (play_pre_track) indicating if the audio track (t) has to be played back seamlessly after a particular other audio track.
Playback apparatus for reading audio data (A) stored as audio tracks (t) in audio files and associated management information (m) from a record carrier (D) and for playback of a read audio track (t), said management information (m) including seamless playback information (play_pre_track) indicating if the audio track (t) has to be played back seamlessly after a particular other audio track, the apparatus comprising reading means (21) for reading the audio track (t) and said management information (m) from the record carrier (D), the apparatus further comprising management information evaluation means (22) for evaluating said seamless playback information by playing back the read audio track (t) seamlessly after the particular other audio track in dependence of the seamless playback information.
Method of reading audio data (A) stored as audio tracks (t) in audio files and associated management information (m) from a record carrier (D) and of playback of the read audio track (t), said management information (m) including a seamless playback information (play_pre_track) indicating if the audio track (t) has to be played back seamlessly after a particular other audio track, wherein said seamless playback information is evaluated by playing back the read audio track (t) seamlessly after the particular other audio track in dependence of the seamless playback information.
A transmission signal comprising audio data (A) representing audio tracks (t) and associated management information (m), said management information (m) including a seamless playback information (play_pre_track) indicating if the audio track (t) has to be played back seamlessly after a particular other audio track.
