Testing Software / Benchmarks

• CoolEdit Pro and CoolEdit96 include a FFT with up to 64k points.. The imbedded test signal generator creates a variety of sine wave and random noise based signals. CoolEdit Pro has support for long data words (> 16 bits). See http://www.syntrillium.com/indext.htm for more information and hobbled demo versions.
  
  
• Goldwave also does spectral analysis. Its mathematical-expression based test signal generator can be very flexible if you know some math. Full function demo at http://www.goldwave.com/.
  
  
• Spectra Wave and Spectra Lab are easy to use, quite flexible, and have very nice real-time analytical capabilities. The Lab version has support for long data words. You can find 30 day full function demos of this software at http://www.telebyte.com/pioneer/ and http://www.pmgrp.com/prod01.htm
  
  
• ETF stands for Energy Time Frequency analysis software - arguably far better than simple spectral analysis for testing things like speakers. http://www.etfacoustic.com has more information and informative demonstrations you can download.
  
  
• Liberty Audio Suite is a classic and uses the DSP of Turtle Beach Fiji and Pinnacle cards to speed operations. It deserves a look at http://www.libinst.com/.
  
  
• Most aggressive, performance-wise, of all the spectral analysis programs I've tried is HPW Works, with support for up to 1 million point FFT's. HPW also has top support for high sample rates and long data words. Swiss precision strikes again! HPW includes a very nice signal generator that creates very low distortion test signals and the multitone signal I use for frequency response testing. The author also works in English, is very responsive to suggestions and provides quick technical support. The "Lite" version of this software may be found for download at HpW Works
  
  
• Take a look at Clio, another European offering: http://www.mclink.it/com/audiomatica/products.htm


• Sample Champion is a new product that looks like it has a lot of potential, especially since a Signal Quality module has been added. http://www.purebits.com
  
• Many academic folks like Siglab. For more information check out http://www.dspt.com/sig/saglab.html
  
  
• Analyzer2000 looks like the beginning of something interesting. You can check out thelr latest version at http://www.brownbear.de/
