Wavelet frames for L2(\mathbb R) can be characterized by means of spectral techniques. This work uses spectral formulas to determine all the tight wavelet frames for L2(\mathbb R) with a fixed finite number of generators of minimal support. The method associates wavelet frames of this type with certain inner operator-valued functions in Hardy spaces. The cases with one and two generators are completely solved.
