Summary | This software reads a list of audio files (in supported formats by AFsp), extracts the audio summary for each audio file by applying sub-band analysis, and generates summary audio clips in the same format as input and a description file for an audio slide show. It adopts the AFsp library for audio file I/O. |
Strong Points | This tool can extract an appropriate summary audio clip especially from vocal music. |
Limitations | The duration of audio summary for each slide component is fixed (15 sec). This tool extracts one summary clip from one whole (individual) audio file. The SyncTime element has not been implemented. |
Known Problems | No specific problem is found. |
Parameters | Parameter file is not used. Application name, database file name and bitstream file name are provided by command line option ([-a], [-l] and [-b] respectively). A batch file is provided. |
