Audacity Forum

One option is to connect a simple "frequency doubling" circuit to the sound card's output. Since you specified a single frequency, I am assuming you want a continuous wave. For a sine wave, you can generate 20KHz in Audacity, and then build this one transistor circuit to derive 40KHz. http://electri...

The envelope tool is very useful, as is the Nyquist "env" function. But I was thinking of something more like a look-up table, where amplitude points (Y values) are entered at preset X intervals. In other words, a manual process that does not rely upon algebraic functions. The objective is to maximi...

I am looking for the capability to apply an arbitrary waveform envelope to an audio signal. Something more complex than what can be implemented with ADSR. Is there any way this can be accomplished in Audacity? CoolEdit/Audition has a drag-and-drop graphical editor for this purpose, but I wouldn't mi...

The responses so far have been excellent and straight to the point. Having the procedure for these type of basic "non-musical" wave functions clearly given in the manual might be worth looking into. Apart from sound synthesis, they make Audacity useful as an AF function generator for electronics ent...

It would be great if AM and FM were available in the drop downs, as in Adobe Audition. Seeing as they are not, I am looking for _exactly_ what to type in the Nyquist prompt box. I don't want to spend hours learning Nyquist just to derive two functions, eg. AM and FM of sinewaves. That's all I, and p...

Is there any way to generate test waveforms in Audacity using standard algebraic math expressions, such as sin(2*pi*t*f) for a sine wave?
