FFT Bin Information

I am currently working on a project where I am conducting a Fourier Transformation of a waveform, and want to extract the decibel information for each frequency bin. However, I cannot find a way to do this in Max MSP.

I have looked into cartopol but can't find a way to output the decibel information of each frequency bin and generate a list with the index as the frequency bin?

I am fairly new to Max and could be missing something really obvious, but I have done hours of research to no success.

Any help or advice would be much appreciated as the frequency bin information is really important to the project.

Thanks
