This is a sample application built with DataIO/X showing how it is possible to very quickly and easily read and write WAV audio files. Instead of having to do the difficult task of processing complex binary files, DataIO/X makes life easier for you to get on with programming your application by providing all the functions necessary. The sample applications are included with full source code so you can see how easy it is to use the control.

The following example shows how to read WAV audio files using our component. Just two lines of code is all that is required to read in a WAV audio file. Combine this component with DataIO/X to to determine a speech waveforms formants, pitch, Cepstrum, or even a full spectrogram! Couple both components with a graphics component and you will quickly be able to display speech parameters in a variety of formats. 

Source Code Examples

Here we show the screen shots of sample applications built using the DataIO/X ActiveX component. The full source code is provided with DataIO/X for Visual Basic 6 and Visual Basic .Net. Note that the control itself is coded using C/C++.

Visual Basic 6

This application was built using Visual Basic 6. The processing for each method takes just one line of code to implement, the rest of the application is for the GUI and data display. You are free to use this source code as part of your application if you purchase DataIO/X.



Visual Basic .NET, Visual C#
