Oh, and btw, you dont need a high precision plugin to see the effects of crappy encoding.Anyone who can read Winamp SDK sources may notice that spectrum data Winamp provided to those plug-ins are presented in 8-bit data format.
With 8 bits there are only 256 possible data levels could be shown, so there are no acceptable ways to represent these levels in true logarithmic scale. The difference from another spectrum analyzers for Winamp is that DSP Spectrum Tool gets data as DSP (Digital Signal Processing) plug-in and performes its own Fast-Fourier transformation routines in 32-bit double float number format, so spectrum is displayed correctly even at weak signals. Even a masking noise added to any record before CD-mastering is shownThe other key feature of DSP Spectrum Tool is to analyze and detect poorly-coded MP3 files. These files have a noticeable roll-off after 16kHz and they can be easily found by DSP Spectrum Tool.The spectrum may be shown in two different modes - classic and sonogram plots. Classic view has a peak hold feauture with selectable hold time and a spectrum level meter to measure exact level of each spectrum component. Spectrum view allows to analyze continous frequencies changes over time. Both of the plots has a cursor-related marker to show exact frequency cursor stays at.The level meter shows current absolute and RMS (Root-Mean-Square) levels of left and right channels, detects possible clippings occured while playing. Peak hold is also presented.The look and feel of the plug-in are designed to meet original design of Winamp. But nonetheless, this window steadfastly refuses to display any spectra in response to music, even with the default nullsoft mp3 decoder in place. Also the website for this plugin has been dead for years now, so although you can still register and hand money over for it, it is clearly no longer supported at all.Dont waste your time with this. October 11, 2008 by Ralph Clark Excellent Best for quality examination of mp3-files. This plugin I use every time I want to examine how good a mp3-file really is. Dsp Spectrum Tool Update Would BeSome bugs are killing winamp from time to time, an update would be fine, but never the less both thumbs up. Excellent work - January 12, 2006 by max blue Yay.or not - I think that this plug-in is realy bad becouse i HATE sharewares. This pice of junk is also very syncronized (or not) if you want it to plot about 8 times faster than the song. It crashed after 10 min of usage for me (i was deperatly trying to fix the poor sync in the prop tab). Dsp Spectrum Tool Software When MyMy point is: I would send money to buy this software when my dog can calculate primes (and i dont have a dog) - September 19, 2004 by Hannes Landeholm Ok. Eh its ok for a program, but lets look into the real world: WHY WOULD YOU ACTUALLY NEED A FAST FOURIER TRANSFORM OF THE LEVELS OF MUSIC what are you trying to do impress your friends This an audiophiles toy, not tool, that does an effect that, to tell you the truth, is kind of unneeded. Space signal analyzers use fast fourier transform procedures to measure frequency peaks. Uhh and are we looking for aliens in our eminem and metallica CDs now Maybe we can creat a program that will decrypt MP3s and show you what the secret government message that is encoded is (Actually, i have always wondered what the teletubbies would be saying if you played them backwards, i bet it has to do with saddam hussein) - July 31, 2003 by Digital Ice Smart idea, but only for audiophiles with cash and time. First, this is shareware. It just doesnt seem right to profite off of someone elses work like that. Dsp Spectrum Tool Registration Thing ThatAnyway, after the annoying registration thing that at least doesnt pester you often at all it doesnt bother you with other things from what I saw so far. Perhaps because Im using a plugin that gives me 32-bit output for my playback instead of the normal 16-bit mp3 plugin that comes with winamp. If you really care a lot about the precision of your spectrum analyzer to the point that you are probably an audiophile, then this is probably the plugin for you.
