AudioScience supports several audio APIs for application development. These APIs are WASP, HPI, ASX, WAVE, DirectSound and ALSA in Linux. Consult the extensive user manuals for each type below and contact our support team if you need specific help with a development issue.
WASP (Web AudioScience Protocol) is an HTTP based control protocol for AudioScience devices.
Proprietary low level API, developed by AudioScience that is buffer based. Supported on Windows and Linux. The HPI library functions are natively callable in C/C++ and the SDK includes a wrapper (hpi.cs) that can be included in a C# project and a .NET assembly to support Common Language Infrastructure (CLI) languages (i.e. Visual Basic, C++/CLI, C#, JScript .NET, etc.). Note: Python support is included in the driver installation and does not require this SDK.

Microsoft audio APIs (waveOut, waveIn and mixer). Supported on all flavors of Windows when using the WAVE driver or WDM driver. The Microsoft mixer API and hardware support of compressed audio formats such as MPEG, are only supported when using the WAVE driver.
AudioScience has defined custom mixer control types that are detailed in the following document: WavX - AudioScience Windows Multimedia Extensions
Microsoft low latency audio API. Supported on Windows 2000/XP when using the AudioScience WDM driver.
