I've generated some test tones (100-3000 in 100Hz increments, then 1000Hz incrememnts up to 14Khz) and it seems that the 8-bar Spectrum Analyzer is not weighting the lower frequencies as strongly as it possibly should. I tested using MP3 format as for some reason my SBG2 wouldn't play the WAV formats.
It would appear that the following frequencies correspond to each bar: Code: -------------------- Bar 1 - 0Hz - 1000Hz Bar 1 & 2 - 1100Hz - 1900Hz Bar 2 - 2000Hz - 2500Hz Bar 2 & 3 - 2600Hz - 3000Hz Bar 3 - 4000Hz Bar 4 - 5000Hz Bar 4 & 5 - 6000Hz Bar 5 & 6 - 7000Hz Bar 6 - 8000Hz Bar 7 - 9000Hz Bar 7 & 8 - 10,000Hz Bar 8 - 11,000Hz Bar 7 & 8 - 12,000Hz Bar 7 - 13,000Hz Bar 6 & 7 - 14,000Hz Bar 8 14,000 13,000 12,000 11,000 4000 5000 6000 7000 8000 9000 10,000 2600-3000 2000-2500 1100-1900 0 - 1000 Bar 1 | Bar 2 | Bar 3 | Bar 4 | Bar 5 | Bar 6 | Bar 7 | Bar 8 | -------------------- For some reason frequencies above 11K are begin to appear in lower bars of the analyzer. It would better, I think, if the first 4 bars were used to represent frquencies between 0-3500Hz, with the remaining 4 bars used for frequencies above 3000Hz. This may give a better representation that at present. eg. Code: -------------------- 11,000+ 10,000 9000 8000 7000 6000 5000 4000 3100-3500 2600-3000 2100-2500 1600-2000 1100-1500 600-1000 0 - 500 Bar 1 | Bar 2 | Bar 3 | Bar 4 | Bar 5 | Bar 6 | Bar 7 | Bar 8 | -------------------- I'll take a look and see if I can tweak anything in squeezebox2.pm, but as I know next to nothing about Perl I'm not expecting much success! :) -- Milhouse _______________________________________________ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
