[music-dsp] Matlab question - making avifile movies from plots

2012-01-17 Thread Linda Seltzer
Good afternoon from the intermittently snowy Northwest, Assume a program that starts with initialization, then processes frames of data in a loop. With each iteration of the loop a plot is generated. Because several graphs are superimposed on this plot, I need to use the hold on command. After

[music-dsp] Signal processing and dbFS

2012-01-17 Thread Linda Seltzer
Good evening from snowy Washington State, Those who know me personally know that my background in music DSP is via the ATT Labs / Bell Labs signal processing culture. So for the first time I have encountered the way recording studio engineers think about measurements. They plot frequency

A reasonable and common reference operating level (that is, 0dB on the console VU meters) is -20dbFS. If you're plotting a filter frequency respionse, and label the Y axis so unity gain reads -20dBFS, a recording engineer should be able to make sense of it. -Alex On Jan 17, 2012, at 10:34 PM,

Re: [music-dsp] Signal processing and dbFS

2012-01-17 Thread Nigel Redmon
My understanding is that different manufactureres have different voltage levels that are assigned as 0dB. Not exactly—it's worse than that ;-) dB is a ratio, of course, and there are a couple of popular reference standards. People sometimes talk about a device being +4 (dB) or -10 (dB). The

Hi Linda Some (possibly spurious) thoughts... I'm confused about what you're actually trying to achieve by referencing things relative to 0dBFS (which is measure of signal level relative to digital full scale). You talk about frequency responses below, which are expressed in terms of
