So... if you sell your car and buy the most expensive sound card you can get, your readings may improve by 10-20 decibels.
By doing some digital voodoo, you may increase your match between the original and the resonstructed signal by a few decibels... But beyond that, there's no other way than to shell out a few thousand dollars for better converters. Typically, 24 bit converters have a dynamic range of only about 18-20 bits. The lowest bits are generally just noise, even in the most high-end cards - the maximum dynamic range is around 110-115 dB, rarely above that. Beyond that, it's just noise territory. Since noise is basically entropy (= unpredictability), you cannot "predict" it, hence you cannot "fix" it... That's as best as you can get. -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp
