Re: Received message "Nyquist retturned nil audio"

Please state which version of Windows you are using,
and the exact three-section version of Audacity from "Help menu > About Audacity".

Do other Nyquist effects work? For example the "Pluck" generator or the "High Pass Filter" effect?

Re: custom tone generator help

For "Hz", change this line: ;control pitch "MIDI note number" float "" 60 0 127 to: ;control freq "Frequency (Hz)" float "" 440 1 1000 (setf pitch (hz-to-step freq)) TIP: The defined waveform should normally start an end at zero. This would make the ...

Re: Missing Audio Data Blocks

It has recently been discovered that in Audacity 2.2.1, if you overwrite the current project (the project having been saved previously) using "Save Project As...", then data loss can occur. This issue has been fixed in the soon to be released Audacity 2.2.2. The workaround for people using...

Re: custom tone generator help

How would I mod the code to output any frequency I choose down to 2 or 3 decimal points (i.e. 7.84 or 7.845) instead of musical note value frequencies? You want "Hz" rather than "Note" values? To modify the ";control" line: http://wiki.audacityteam.org/wiki/Nyquist_Plu...

Re: Problem with Time Track Logarithmic Scale

Also, it seems to me that setting time-track control points should operate like the envelope tool, which lets one click anywhere in the track to set a new point. The way things are now the cursor has to be right on top of the line to be able to drag or set a point. Yes, but you don't need to select...

Re: custom tone generator help

No need to RAR the files. Both TXT and WAV files may be uploaded to the forum. I don't think you've said what you are trying to do, but the final 10 values in your data look peculiar. All the other values show a slope of close to 0.000299 amplitude per sample, except for the final 10 samples, when t...

Re: 32 bit floating wav vs 32 bit

My question is that there are 3 different 32 bit choices for WAV files when I export. Are they all the same? Is one better than the other? All 32-bit formats provide excellent quality (virtually "perfect"). 32-bit float is the one that Audacity uses internally, and it is the only one that...

Re: 32 bit floating wav vs 32 bit

During "production" (while you're working on the project), keep to 32-bit float as far as possible. Audacity works internally with 32-bit float, which is a ridiculously high quality format that is ideal for audio production. Working with 32-bit float throughout avoids unnecessary conversio...
