Introduction

Return to chapter overviewNext page

Active Sound Editor is an ActiveX custom control developed by MultiMedia Soft that makes it easy to add sound editing capabilities to applications written with the most widely-used development environments that accept ActiveX controls; thanks to the integration with DirectShow codecs and with the BASS library, both allowing decoding capabilities for the most common audio formats such as MP3, WAV, Ogg Vorbis and many others, Active Sound Editor allows creating powerful audio editing applications.

 

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

Sound composition through the embedded TracksBoard

 

Composing of new stereo or multi-channel (up to 7.1) sound files, with extensive visual editing through the embedded Tracksboard, by mixing together audio data taken from the following audio sources:

- Regular sound files stored inside disk files

- The Microsoft Speech API which allows creating audio data from a string of text or from a text file through synthesized voices installed inside the system

 

All sound items added to the composing session are layered, meaning that they can be added, removed and modified before composing the final mix and exporting the same into a destination file on disk using one between the supported audio formats

 

Tagging features

 

Editing of most common frames of the following tag formats (Unicode strings supported):

 

- APE
