The FreeVIEW-FFT-BOX is a compact 2 channel in/out data acquisition device for recording and analysis including waveform generation. Usuable as FFT Analyzer, Chart Recorder, Data Logger and Function Generator. It features the widespread USB interface and requires no driver installation. In addition to AC inputs it directly supports IEPE-type sensors, such as microphones and accelerometers. The outputs may be used for monitoring, playback or signal generation. SPDIF I/O is supported as well. Filters on the input and output and instrumentation quality amplifiers ensure reliable 16-bit data. With a bandwidth up to 24KHz per channel and simultaneous sampling the Box is highly flexible and may be used with all software packages supporting audio devices. The included FreeVIEW-Sound-PRO software changes the FreeVIEW-FFT-BOX directly into a 2 channel FFT-Analyzer, a long-time Data Logger, a Chart Recorder, a Storage Ossciloscope and offers more than 500 mathematic functions for online signal analysis including a waveform generator modul. The Box comes in a rugged aluminum housing, prepared to go wherever the measurement job requires. Supported operating systems: Win ME, 2K, XP and up; Linux; MacOS (depending on application software.)

FreeVIEW®-Sound-PRO Software Suite

The 32 bit FreeVIEW® sound card driver and the accompanying FreeVIEW® plus application software turns a PC or Laptop into a long-time Data Logger, a Chart Recorder, a Storage Oscilloscope, an FFT Analyzer and much more. The sound card driver supports popular programming languages and applications.

User feedback - Using FreeView-Sound-Pro and Agilent VEE 7, I have now got simultaneous, two channel, 24 bit DAC and ADC at 200kS/s, which is much better than what I could achieve with any of the software applications that I have been using to date.

FreeVIEW®-SOUND-PRO
The full version called FreeVIEW®-SOUND-PRO is included in the standard delivery package. It has A/D and D/A capability (recording and playing), also simultaneously. The Microsoft® Windows 95, 98, ME, NT®, Windows® 2000 and Windows XP® are supported. The sample rate is unlimited only dependent on the technical level of the sound card or the sound box system. For example sound cards with up to 192kHz sample rate per channel and 2, 4, 6 or 8 input channels and 2 output channels both with up to 24 bit resolution and up to 192kHz can be used simultaneously.

Basic features
For writing applications, the driver can be used directly with
• Borland Delphi 5 and higher
• Agilent VEE / HP VEE / DT VEE 
• Microsoft® Visual Basic®
• Microsoft® Visual C++®
Example programs are included in the software package. FreeVIEW plus data logger / scope recorder software, in a special version for sound cards only, is included!

Highlights
• 32 bit driver on top of Microsoft® Windows® multimedia API.
• The driver uses an additional FIFO buffer for intermediate storage. Sampled
   data can be retrieved in arbitrary length. The synchronous data capture is
   decoupled from block-like data processing. No data gets lost! This is a
   significant enhancement over the double buffer principle enforced by the
   original multimedia interface.
• Scaled data is returned in volts unit.
• Simple programming interface using only a few functions open(), close(),
   read(), write() and ioctl().
• Full error handling.
• Shares the features, the interfaces, the style and the experience of ELAN
   data acquisition PCMCIA Card drivers.

FreeVIEW-PLUS data acquisition software, version for sound cards, is included in the FreeVIEW-SOUND-PRO package. No programming required. Immediate data capture and data analyzing capability including Fourier transformation and more of 500 other mathematic and signal analysis functions.

For writing own applications, the sound card driver can be used directly with Borland Delphi 5 and higher, Agilent VEE / HP VEE / DT VEE, Microsoft® Visual Basic® and Microsoft® Visual C++®.
