[R] Power Spectrum from STFT (e1071)?

[ajf226]

Hello.

Does anyone know how to generate a power spectrum from the STFT function in
package e1071? The output for this function supplies the Fourier
coefficients, but I do not know how to relate these back to the power
spectrum.

Alternatively, if anyone is aware of other packages/functions that perform
short time Fourier transforms, that would also be helpful.

Thanks.
