content: Does anybody know about off-line (win7)FREEsoftware for Spectrum Analysis for the Audio frequency range ?One that can also analyse *.wav *.mp3 (and other formats) as input audio source files for their Spectra ?TIA

content: Quote from: JPortici on August 27, 2016, 07:41:50 amDownloaded it (free), tried it on a *.wav file.But it seems to not have a straightforward menu to do parametric FFT.

content: What I mean is Audacity does only Temporal Spectrogram - not FFTHere is an example of a 10-digit DTMF tone *.wav file.I need to do a straightforward spectrum analysis (a 2-axis Frequency Domain/DB) on it with a parametric FFT.

content: Quote from: JPortici on August 27, 2016, 09:22:59 am- Audacity: Analyse -> Plot Spectrum - much better !, but there seems to be no control on frequency (neither range or Center)- Goldwave: Yes tried it. Very lousy display options. As a matter of fact - not so great

content: Quote from: JPortici on August 27, 2016, 10:02:04 amVisual Analyser:Seems like an excellent Spectrum Analysis tool (and more) with rich control parameters.However, after digging deep into most of its menus, it seems (or at the least - couldn't find) not to accept audio sources files as inputs. It seems to work only on Windows Audio Devices as inputs!Anyways - Thanks much for your help. Appreciate that.

content: Spectrogram 16 is still available, download fromhttp://db0fhn.efi.fh-nuernberg.de/~dg8ygz/voicetools/Set to "scroll" for a spectragram or "scope" for FFT plot. User has no control over FFT size, window type or the amount of overlap unfortunately.

content: Quote from: roli_bark on August 27, 2016, 11:22:08 amThere is a freeware version available. You only can't save .pir files (impulse response).But you can export everything, so it's not a big deal.

content: Ok, Tried 'ARTA' in demo mode.When I import a *.wav file, it limits the importation to a max of 256K samples.My *.wav file contains much larger samples than this.Is there a way to increase this limit ?

content: Quote from: roli_bark on August 27, 2016, 09:58:23 amDid you try selecting part of the data and look at the spectrum? Range of a spectrum is limited by sampling frequency and size of the bins (frequency resolution) by the number of points.

content: Quote from: roli_bark on August 27, 2016, 10:53:23 amthe website says wave file support but i'm not sure what it actually means...at this point just open matlab/octave/scilab, import the file into a matrix and use their signal analysis tools.

content: You could check out Room Equaizing Wizard. No idea if it does what you need (I am an ARTA user), but is does seem to have quite some features and it is free:http://www.roomeqwizard.com/index.htmlhttp://www.roomeqwizard.com/help/help_en-GB/html/spectrum.html#top

content: Found this "Pratt" program.Very nice.Although designed mainly for Spectrogram Analysis (for speech synthesis, recognition, and more)it has Spectrum FFT display as well. With all necessary parameters config to control the FFT.Control capabilities as per my needs: Reading in an Audio file, Points, Center Frequency, Range, etc.Free:http://www.fon.hum.uva.nl/praat/
