How to retrieve information about loaded songs |
|
Active DJ Studio can easily retrieve information about the song contents.
If you work with single song files you can:
| • | Load a song file through the LoadSound method. |
| • | Retrieve the sound duration through the SoundDurationGet and/or SoundDurationStringGet methods. |
| • | Detect the initial and final silent portions; see the How to detect silent portions of sound files tutorial for details. |
| • | Force the control to retrieve information below, that could require some more CPU tick, using the ReadSoundInfo method |
| • | Retrieve the song bitrate through the GetFrequency method |
| • | Retrieve the number of channels of the loaded song through the GetChannels method. |
| • | If the loaded song is in MP3 format, use one of the following methods in order to get detailed information: |
If you work with playlists you can:
| • | Create and fill a playlist (see How to create and manage a playlist). |
| • | Use the PlayListGetItemString in order to receive one or more strings containing the needed information. |
Sound files in WAV format may contain information stored inside "chunks": Audio DJ Studio can retrieve contents of BEXT and CART chunks in the following way:
| • | Load a WAV file through the LoadSound method. |
| • | Force the control to perform a deeper analysis using the ReadSoundInfo method |
| • | Check if the loaded WAV file contains CART and/or BEXT chunks through the IsWavChunkAvailable method. |
| • | Obtain single fields of the chunks using one of the following methods: |
* GetWavChunkStringInfo for string fields
* GetWavChunkNumericInfo for numeric fields
* GetWavChunkBinaryInfo for binary fields
Tags contents can be obtained through a set of dedicated methods: see the How to read TAG information in sound files and How to retrieve basic TAG information from the sound loaded into a player tutorials for details.
