Re: How accurate is the "Plot Spectrum" function?

1024 You can get into trouble with low readings like that. There's something magic about very low frequencies I don't remember very well, but the displays turn into blobs if the size is too low. Something similar happens to a vocal rumble filter popular with the audiobook crowd. That only works wel...

Re: Improve "over edited" file

It's going to be very difficult to beat Episode 3. If I had to find something wrong: — I would have panned the American interview center even if I had to do that segment in mono rather than stereo. Suddenly having the whole show coming out of one side is very odd, particularly if the listener is on ...

Re: Improve "over edited" file

Episode 4 is now out. This is exactly what it sounds like when someone sets up a video camcorder across the room, presses the little red record button and does a show. Echo city. You have strike two in addition to that. The accents of the actors would normally give spice and variety to the presenta...

Re: Improve "over edited" file

When it's not over the top (catalan coffee machine in episode 3), I actually find it quite pleasant to have a reasonable amount of background noise. It's totally pleasant. There are Hollywood awards given to people who can produce that effect on cue. There are demonstrations where you get to watch ...

Re: How accurate is the "Plot Spectrum" function?

assume the peaks changed because you changed the "Size" setting in Audacity? No. I amplified the sound sample by roughly 2dB between the measurements. All other windows and settings are the same. That's the oddity. Normally you would assume the spectrum would go up and down 2dB, but inste...

Re: How accurate is the "Plot Spectrum" function?

We get in trouble every time somebody starts asking about surgical accuracy. Audacity is a sound and show editor, not a scientific instrument. If it's a tossup between sounding good and perfect, bit accuracy, Audacity will pick sounds good.

Re: How accurate is the "Plot Spectrum" function?

Pay attention to the left-hand scale The top value of the blue waves is always 100% (1.0) and the top number on the sound meters is always 0dB (unless you intentionally change them). Plot Spectrum left edge runs on a sliding scale. Attached I did a Plot Spectrum on Pink Noise. One timeline show is ...

Re: How accurate is the "Plot Spectrum" function?

A word on the Size setting. We had a complaint a while back that analyzing a single pure tone didn't give the expected sharp spike. Turns out, they had the Size setting too low and the display was sloppy, but please note that a perfect, correct display in this case is invisible. A perfect spectrum d...

Re: How accurate is the "Plot Spectrum" function?

It does have a couple of oddities it's good to know about. The accuracy goes up as you drag the screen bigger and bigger. This can partially make up for the lack of Zoom. The display depends on the settings. The Size setting can be managed for extreme accuracy at the risk of missing tiny details bec...

Re: Waveform disappeared! Please help :(

I wake up and I derp around on the computer first for a while.... ... I've heard of software that can restore deleted files If you or the machine did anything to save work during that interval, "undelete" is probably gone. When you "delete" files (and we don't know yet exactly w...
