== Explanation of input data please == |
|||
Hi. A big problem with pages such as this (and I challenge you to try finding FFT information anywhere else on the internet which is simpler) is the lack of explanation of various parts of the explanantion. |
|||
To explain: The code is nicely clear in the various langauges but no mention is given of what the input data is or what the output data is. I am looking for FFT information in the context of feeding in WAV data (audio) and getting out an array of frequencies for a particular time-frame (say 100ms). This 1,1,1,1,0,0,0,0 is meaningless without an explanation. |
|||
Could somebody please fill in the blanks for the rest of us? |
|||
Note to others: You can never put enough information in these articles. Assume everybody is in the dark about something... |

Thank you |

Possible renaming
Would this be better named as "Fast Fourier Transformation", rather than just the initials? Markhobley 06:33, 11 July 2011 (UTC)
- Or "Fast fourier transform"? --Paddy3118 07:38, 11 July 2011 (UTC)
- Wikipedia uses “Fast Fourier transform”. This would fit with our capitalization policy (since “Fourier” is a surname). –Donal Fellows 07:52, 11 July 2011 (UTC)
- When I google for fft my first hits are the relevant ones. I suspect it's good enough, though we should probably link FFT to one of those pages, just in case. --Rdm 08:10, 11 July 2011 (UTC)
