Which mother wavelet for a scalogram? I'm attempting to create a real-time scalogram (from a 1 dimensional signal) in the style of a spectrogram;

Looking through various papers+books; the Gabor wavelet, or complex Morlet seems to be favoured for keeping a close relation to frequency.

Though I was hoping to use a real valued wavelet though due to computational complexity concerns... What wavelet would be recommended?
The mother wavelet of your scalogram should have a similar shape to the usual peak shapes you want to detect (I suppose you use it to detect peaks of your signal).
However, I would like to ask you what would you like to use wavelets for? I could give you a more specific answer for your question.
