Re: Overdub problems

... and Audacity to prevent problems. Try setting Audacity and Windows to 48000 Hz which is probably the native UCA 200 rate. Please see here for help: http://wiki.audacityteam.org/wiki/Windows_7_OS#sample_rates . Gale

Re: Hello Need Help With Recording

Audacity is not a video editor, only audio. Have you enabled Transport > Software Playthrough so you can now hear yourself recording? There may be better ways to hear yourself. What version of Windows are you on? Note that you should have copyright permission to reuse instrumentals from YouTube. I s...

So that is a special case where the signal lies dead centre of one of the frequency bands.
Center, or bottom? 173 Hz seems to correspond to the bottom of the band on the vertical scale.

Re: Help me understand spectrograms

I do find spectrogram useful with the defaults. I can often zoom right in on a crackle inside recorded speech, which would be hard to hunt for in waveform view, but I use waveform dB view for a precise selection. The trick of synched tracks with identical contents, one of them mute, is useful. Anywa...

Re: Help me understand spectrograms

For Nyquist programming, the Hann (Hanning) window function is often a good choice, both for its characteristics and because it is easy to generate in Nyquist. ; wlen is the windowsize in seconds (local time) (mult 0.5 (sum 1 (osc (hz-to-step (/ wlen)) wlen *sine-table* -90))) http://en.wikipedia.or...

Re: Help me understand spectrograms

... where the frequency is not dead centre and you will see that Rectangle window gives a much wider spread of "side lobes". Windowing can help to minimise the side lobes, but it is always a compromise between time domain, frequency domain main lobe width and frequency domain side lobe ...

... want to read through that -- probably more than once. We're going to send you a basket of fruit or something. Nobody ever wants to hang around and help with projects like this. And I suspect you are doing as well as you can possibly do while using one machine. Do you have anything else that will ...

Re: Help me understand spectrograms

I noticed significant problems with the display. I put a known audio clip in and I didn't get anything I thought I could use for diagnostics. The answer is the tool is intentionally "crippled" in order to use minimum resources and complete at reasonable time. You can greatly increase the q...

Help me understand spectrograms

Not sure which is the right board to ask this mathematical question on... anyway: Where can I learn about the window type options for the Spectrogram preferences? Generate a sine wave at 172.265625 Hz. That makes the period equal to 256 samples at 44.1kHz sampling, and so equal to the default window...
