Audio DJ Studio for .NET is a .NET Windows Forms custom control developed by MultiMedia Soft that makes it easy to add sound playback and mixing capabilities to Winform and WPF applications written with Microsoft Visual Studio; thanks to the integration with DirectShow codecs and with the BASS library, both allowing decoding capabilities for the most common sound formats such as MP3, WAV, Ogg Vorbis and many others, Audio DJ Studio for .NET allows creating powerful multimedia applications with stunning playback capabilities.

 

Audio DJ Studio for .NET can load different sounds at the same time on different virtual decks, known as "players"; a player can be compared to a physical deck on a DJ console, the place where you put the vinyl/CD to be played. You can create a console with many virtual decks that can simultaneously play different songs on one or more sound cards. The availability of a certain number of players (decks) will enable the container application to mix several songs on different output channels, giving for example the ability to play advertising spots while songs are being played/mixed on different output channels: this is very useful for multi-channel radio stations automation software

 

Each player can have separate volume, tempo, playback rate, pitch and equalizer settings; each player also comes with a set of embedded and configurable visual feedback components such as VU-meter, spectrum analyzer, oscilloscope and waveform.

 

An embedded automatic fader can easily mix audio tracks loaded inside a playlist with an accurate and configurable fade-in/fade-out.

 

Many tutorials are available to help you beginning your developments with this powerful control.
