Tutorials > How to retrieve information about loaded songs

Audio 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 GetSoundDuration and/or GetFormattedSoundDuration methods.

•

Detect the initial and final portions of silence through a call to the RequestSoundSilenceDetection or the DetectSoundSilence methods: silence portions can also be detected automatically during a LoadSound call if the SetAutomaticSilenceDetection has been previously called; once detected, the container application will be notified about the positions of silent portions through the SilencePositionAvailable event.

•	Force the control to perform a deeper analysis using the ReadSoundInfo2 method

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 ReadSoundInfo2 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.
