> Wavelet transforms can be a good way of separating a signal into coarse features and fine features, but it's important to understand that they don't decompose it into sinusoids, as Fourier transforms do. So, if when you say you want to "isolate certain frequencies", you mean frequencies of sinusoidal components, then Fourier analysis is probably more appropriate.
