Use of this component requires that you download the full "Audio Sound Recorder API for .NET" package from their website https://www.multimediasoft.com/bins/asrecnetapi_t.exe The full downloaded package comes with extensive documentation and a lot of C# and VB.NET sample projects that help reducing the learning curve. Audio Sound Recorder API for .NET is a .NET class that adds sound recording capabilities to multimedia applications it's designed to work directly with your sound card or with your CD player. Custom DSP effects are also supported: you can create your own DSP effects and apply them to the sound being recorded. Derived from the experience with the Audio Sound Recorder for .NET Winforms component, this API can be used not only for developing Winforms or WPF applications but also for developing console applications, Windows services, server-side ASP.NET web applications 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.

$ dotnet add package AudioSoundRecorderApi.TrialReadme
Audio Sound Recorder API for .NET is a .NET class 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 API for .NET allows creating powerful audio recording applications
Audio Sound Recorder API 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 API in conjunction with our Audio DJ Studio API for .NET.
Derived from the experience with the Audio Sound Recorder 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, server-side ASP.NET web applications 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.
Audio Sound Recorder API for .NET supports deep analysis of the recorded sound waveform with rich visualisation capabilities including range selection, zooming and panning. Recorded sounds can be edited, resampled, mixed with other sounds and exported to different formats.
Many tutorials and sample projects are available to help you beginning your developments with this powerful component.
