график из wav-файла без log-зависимости

[IljaO]

Здравствуйте, уважаемые!
Возникла потребность расковырять содержимое wav-файла, грубо говоря - получить координаты X и Y из области данных. Никто не сталкивался с данной проблемой?
P.S. Во всех программах типа Adobe Audition график построен в логарифмической зависимости.

Поставь. Там в примерах есть примерно то, но не совсем.
Разбирайся.

Вот начало RelNotes:
Intel Signal Processing Library 4.5
The Intel® Signal Processing Library provides a set of signal processing functions for the Intel Architecture similar to those available for most Digital Signal Processors (DSPs). The computing power of the Intel® Pentium® processor family enables many signal processing functions which were previously done by add-in DSPs to be done natively on a host Intel Architecture processor. The library includes functions for FIR, IIR, and LMS filters, fast Fourier transforms (FFT), discrete cosine transforms (DCT), wavelet transforms, tone generation, and many arithmetic and vector operations.

The Intel Signal Processing Library is optimized to support all Intel Architecture processors. The library includes code optimized for the Pentium® III processor, Pentium II processor, Pentium Pro® processor, and Pentium processor with MMXTM Technology, as well as a version with blended performance to support all legacy processors.

Additional information on this software as well as other libraries is available at the Intel Performance Libraries homepage.

System Requirements
The Intel Signal Processing Library requires the following software and hardware:

Recommended hardware: A Pentium II or Pentium III Processor-based PC with memory appropriate to the signals needed.

Software Requirements: Windows* 95, 98, or 2000, Windows NT* 3.51 or 4.0.

Compiler Support
The Intel Signal Processing Library has been tested with the Intel C/C++ Compiler, Borland* C++ v5.0, and Microsoft* Visual C++ v6.0. Although it is possible to use other ANSI C compilers, their usage has not been verified.

The library also includes interface support for developing applications using Microsoft Visual Basic*, Borland Delphi*, Microsoft Visual J++*, and Digital* Visual FORTRAN*. For details, please check the readme files in each support directory.

В атаче два проекта в исходниках, из примеров к библиотеке, и длл. Возможно этого хватит для запуска.
Удачи
