The signal package is part of the Octave Forge project and provides signal processing algorithms for use with Octave. The functions provided by the signal package include creation of waveforms, FIR and IIR filter design, spectral analysis, Fourier and other transforms, window functions, and resampling and rate changing. There are also some wavelet functions included, because there is no separate wavelet package, at least for now.
You may also be interested in the LTFAT package.
