I’m using Windows version 2.3.3, and have a question on Effect → “Base and Treble” question.
Suppose I use Base=0 dB and Treble = 5 dB. What is the equivalent or approximate adjustment for Effect → Graphic EQ?
The reason for this question is that I play with different settings in “Graphic EQ” but can’t find an ideal setting to make sax brighter. When using Base=0dB & Treble=5dB in “Base and Treble”, I can hear sax sound getting improved. So if I know the equivalent Graphic EQ settings for Base=0db & Treble=5dB, then I can possibly make fine adjustment around this equivalent Graphic EQ setting to further improve sax sound.
Whatever the number is on the bottom of the vertical axis of the frequency-analysis plot, add that number to any other number you read off that axis, e.g. If it says “-22db”, add **+**22 to all the other numbers.
It looks like every single section of the track occupies from 0 Hz to 8 KHz. If I zoom in to the section that sounds brighter, this section looks like this:
The plot has different colors (blue, yellow, orange, red…). How can we tell which frequencies has what intensity from this plot? Can Audacity show another curve for the focus point (where the black vertical line is at), and let this curve use horizontal axis for frequency (e.g. 0 - 20 KHz) and vertical axis for intensity (dB)? This way, we can see what frequencies have more intensity at this focus point.
Plot spectrum will do that … Plot Spectrum - Audacity Manual
but you have to select a short* section of audio, rather than a line.
[* the minimum selection is ~1/100th of a second for plot spectrum]
