Audio solutions for companies (using our product Alvas.Audio) and audio toolbox for .Net developers. Our client says:

After looking for an audio recording interface for our software I selected Alvas Audio because of its features and the excellent support offered by Alvas. On two occasions we required some extra functionality in our software. I contracted with Alvas for the code development. In both cases Alvas provided clean well written C# code to implement our functions on schedule and on budget. I highly recommend Alvas Audio.
