Introduction

Return to chapter overviewNext page

Active Waveform Analyzer is an ActiveX custom control developed by MultiMedia Soft that makes it easy to add sound waveform analysis capabilities to applications written with the most widely-used development environments that accept ActiveX controls.

 

Active Waveform Analyzer comes with native decoding capabilities for many audio formats and leverages decoding capabilities of Microsoft Media Foundation and Microsoft DirectShow for audio and video formats not supported natively.

 

Active Waveform Analyzer can be easily integrated with existing third-party audio libraries like Leadtools Multimedia SDK, BASS, FMOD and any other multimedia library supporting the possibility to start a playback session and/or the possibility to decode and provide the PCM data for rare or custom audio formats.

 

Some tutorial is available to help you beginning your developments with this powerful control.
