Audio Sound Recorder for .NET is a .NET Windows Forms custom control developed by MultiMedia Soft that makes it easy to add sound recording and CD ripping 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 Sound Recorder for .NET allows creating powerful audio recording applications
Audio Sound Recorder for .NET 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 Audio DJ Studio for .NET component.
Audio Sound Recorder for .NET 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.
