Spectrum Analyzer for analyzing static WAV files

[percy]

what PC based spectrum analysis tools can accept an already recorded WAV file and generate a FFT ? Like RMAA - besides a 'dynamic' spectrum analyzer it will also allow to open an already recorded wav file and do spectrum analysis on it. Any others out there ?
VA (Visual Analyser) is good but it doesn't do existing wav files.

I have tried GoldWave but the problem with those 'audio editing' wares is that their FFT's look as if they were made for a kid in playschool, besides not having the resolution that a serious spectrum analyser should have.

Not free but pretty good:

I have this ancient program called WaveSpectra. I don't know if this is what you need or not; I just remembered that it can open .wav files and does FFT.

A new version of WaveSpectra is available, it's excellent.

Indeed there is. Thanks, I didn't realize it was still in development.

I think Audacity can do it.

If you run Linux, or are willing to work with a LiveCD, you might check out BaudLine. It's an incredibly powerful signal analysis tool, very accurate FFT with long-term averaging, spectrograms, and a lot more. I have fun just playing with it sometimes...

Stienbergs wavelab can do FFT plots with great accuracy. I ahve used it many times to look at the spectra of a static wave file. it's not cheap. but you might be able to find an older version on eBay.

free SwCadIII - LtSpice can read .wav files to control BV or BI sources, can then use all wave analysis options on the .wav or its simmed performance driving circuits - fft allows millions of points, many types of window functions, smoothing filter, waveform arithmetic

free SciLab is a MatLab work-alike that can read in .wav and do extreme numerical processing and plotting - default is 16bit wav, you need the xwave read/write .sci files on the contributions page of the website for 24 bit .wav

WaveSpectra was awesome, loved it.
Their WaveGene (wave genrator) also turned to be something I was the lookout for a while!

And one of these days I will manage to start using LtSpice and Matlab!

Thanks!

Praxis can read in WAVs, do scads of processing, FFTs, filters, and can write out processed WAV files too. Even when run in its "free" mode.
