Introduction

Return to chapter overviewNext page

Audio Sound Editor API for .NET is a .NET class developed by MultiMedia Soft that makes it easy to add sound editing capabilities to your Windows applications; thanks to the integration with DirectShow codecs and with the BASS library, both adding decoding capabilities for the most common sound formats such as MP3, WAV, Ogg Vorbis and many others, Audio Sound Editor API for .NET allows creating powerful audio editing applications.

 

Derived from the experience with the Audio Sound Editor for .NET Winform component, this API can be used not only for developing Winform or WPF applications but also for developing console applications, Windows services or any other application not requiring a user interface. Thanks to COM interoperability, the API can be invoked from legacy development environments such as Visual Basic 6 and Unmanaged Visual C++ with our without MFC.

 

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