Hi folks, I'm looking for something that can take soundfiles and display various analyses of them. Any recommendations? Something very much like what you can get with Spectralab, for example these plots: http://www.pcavtech.com/soundcards/ht1869/index.htm ... but free software and working on linux :-] Basically the main thing I need is a good display of log frequency vs. dB amplitude, averaged over the whole file, useful for e.g. getting a frequency response from a swept sine wave or white noise. Other analyses that would be handy at various times: signal to noise ratio and total harmonic distortion given a known input. Also really nice would be a clearly labelled sonogram showing log frequency against time. So far I've been using snd, which has a decent sonogram but kinda falls down on readability: e.g. it doesn't display the actual frequencies of the scale if you select log frequency, it's just 0 to 1.0 so I have to guess, or click on a part of the graph to find out about that particular spot. -- Paul Winkler http://www.slinkp.com
