Re: Analysis of Surface Electromyography-Signals

The Nyquist SND-AVG function has the option to compute the RMS value of a "block" of samples. I assume that this is what we need here. SND-AVG computes either the peak of a block of samples, or the average of a block of samples, depending on whether the final argument evaluates to 1 or 2 ...

Re: Questions about switching to Audacity 2.0 from 1.3.7 on

You can install Audacity 2.0 with Audacity 1.3.7 still installed. Audacity 2.0 will not overwrite Audacity 1.3.7 The only problem with not uninstalling 1.3.7 is that Windows can only associate file types with one version of Audacity, so for the other version you will need to open projects from the F...

Re: Playback sound.

ps.If Audacity is better than abbey road, Subject to hardware. I think the problem with your recording is: 1) A very poor sound card. Are you using the built-in sound card of your computer? 2) Electrical interference, possibly from the power supply. Are you using a laptop computer? If so, try runni...

Re: Analysis of Surface Electromyography-Signals

In order to compare signals it would be helpful to integrate over the signals (=>area underneath the RMS-graph) with varying intervalls. An intervall could be the entire selection ( which the RMS-command was applyied to), but more useful might be to divide the selection into multiple intervalls and...

You've not said, but is this a USB cassette player?

If it is, the device will appear as a Recording device in the Window Sounds control panel (see here: http://wiki.audacityteam.org/wiki/Mixer ... es#vistacp )
