Synopsis

The fixedtones driver provides access to sound hardware, via the Linux OSS interface. Incoming sound is put through a Discrete Fourier Transform, and the frequencies and amplitudes of the five highest peaks in the frequency domain are determined. Note that the FFTW library is required; this package is available (also under the GNU GPL) from: http://www.fftw.org. The fixedtones driver can also produce fixed-tone sounds of given frequency, amplitude, and duration.
