Hello, I am new on this list and I have a question. The source code for the spectrogram includes the following line: double dBFS = 10 * log10 ( p > magnitudes [ i ] * p-> block_norm ) ; I'm not sure, but the product p-> magnitudes [ i ] * p-> block_norm describes an amplitude spectrum and not a power spectrum, right? If so, then it should be 20*log10(...) instead 10*log10(...) with an output displayed in dBFS. I would be grateful for an explanation, thank you. Markus Glugla |
