Have a search on -devel, or ask Leland. When we were redesigning Metadata Editor sometime early in 1.3, there was a drop-down panel added to it. I can remember seeing it. I think Leland has gone off radar, but thanks for the tip, I'll have a look in some old 1.3 versions. If you never go into Prefs...

Try booting into Gnome fallback mode (if that is still an option in Ubuntu). The "motorboating" is usually an indication that data is being dropped because some part of the system can't keep up. Reducing the load on the computer may help, particularly if the computer is not very powerful. ...

Even if AAC metadata works for your listener's media players, are they supported by NCRA Exchange and SoundCloud? I'm not trying to tell you how to run your show, I'm just putting forward some possible solutions that you may not have previously considered. I had a quick look at the NCRA Exchange. I ...

Wouldn't it just be added to ShuttleGUI? A slidedown on one effect could be added in a few minutes. In that case I'm not sure what you mean by "a slidedown". Is there anything like it currently in Audacity? I've been trying to make an "interactive GUI" where controls can appear ...

This gives pretty good accuracy even with noisy sine waves, though it is still very inefficient and slow. For a pure sine tone it gives a pretty good result (without the pre-filtering) with just a single cycle. Disclaimer: This was written quite quickly - there may be errors. In particular I'm not s...

You are going to need some test signals to get an idea of the accuracy of your analysis. Here's a bit of code for generating noisy sine waves at a specified frequency: ;;; Generate test tone: (setq freq 440) ; average frequency (setq max-offset 20.0) ; Low frequency bias (setq gain-variation 10.0) ;...

A major problem with achieving accuracy is that the results are badly affected by noise. This is why it is necessary to take an average over a lot of cycles. The results can be improved significantly by pre-filtering the signal to isolate the sine tone as much as possible. For example: ;; Pre-filte ...

What actually do that values represent ? And what part of the code snipplet actually does calculate those values ? Could you please elaborate about t in some detail, I just didn't get it ? First the disclaimer. My code was intended only for proof of concept. It extremely inefficient, but it is simp...

Get the isolation so sharp that the sine wave is all that is left. Do it over time so chances of a musical performance at 120 Hz is very low. Reverse the phase and add it to the show. There's the first problem. Notch filters (in fact most filters) change the phase. Fortunately not in an unpredictab...

And not sure about "media player then drags in each of the songs, jingles, introductions, etc. in sequence." Our digital library will store music as high quality audio files for broadcast (possibly lossless), how will they be converted to internet grade mp3? And how does the listener get ...
