Active Sound Recorder is an ActiveX control custom control developed by MultiMedia Soft that makes it easy to add sound recording and CD ripping 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 sound formats such as MP3, WAV, Ogg Vorbis and many others, Active Sound Recorder allows creating powerful audio recording applications

 

Active Sound Recorder is designed to work directly with a sound card or with CD/DVD player, so you can record almost any audio source including a microphone, a line-in jack or a CD player (CD ripping), at near-perfect quality. This makes it ideal for implementing a variety of audio applications from music recording and editing to powerful dictation applications.

 

Recorded sounds can be kept in memory for later use or stored on the hard disk in any of the supported formats or using the ACM codecs in the system. Once a recording session has been completed, it is possible to play the recorded audio using the embedded playback system. If you need more sophisticated playback features (such as changing the tempo or pitch), consider using this component in conjunction with our Active DJ Studio component.

 

Active Sound Recorder supports deep analysis of the recorded sound waveform with rich visualization capabilities including range selection, zooming and panning. Recorded sounds can be edited, resampled, mixed with other sounds and exported to different formats.

 

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