Intel Signal Processing Library Demos

This page provides a description of the FIR and Dial Tone demos of the Intel Signal Processing library. To download and install the library executables and demos, click on Download and Install.

FIR Demo Description
The FIR demo shows how to use Signal Processing Library functions to show the frequency response characteristics of FIR filters based on library functions. The Intel Signal Processing Library Reference Manual describes these functions in detail.

The FIR demo program is an example of using the Intel Signal Processing Library functions. The program lets you manipulate filter parameters with slider controls and observe graphically the frequency response of an FIR filter based on the Signal Processing Library's FIR filter function.

Dial Tone Demo Description
The Dial Tone demo shows how to use Signal Processing Library functions to manipulate touch-tones used in telephony. The Intel Signal Processing Library Reference Manual describes these functions in detail.

The dialtone demo program uses the Intel Signal Processing Library functions to encode and decode touchtone (DTMF) signals. The program uses only standard Windows* API calls.

Installing and Running the Signal Processing Library Demos
To run the Signal Processing Library demos, you must first download spldemo.exe. Afterwards, you must execute firdemo.exe and dialtone.exe to run the FIR and Dial Tone demos respectively. See the readme.txt files in \examples\firdemo and in \examples\dialtone for instructions on how to use the FIR and Dial Tone demos respectively.
