Re: Audacity "connects the dots" when you zoom in

Perhaps you're not seeing what I'm seeing. I don't just mean that it's not snapping to the sample boundary. I mean it's way off. Here is the result of the described steps with un-patched Audacity 2.1.3 RC2 version. Note that the selection fits almost exactly in the available window area: fullwindow0...

Re: Soundcard to record Ultrasounds

Most sound cards for audio go up to 192 kHz sampling rate max. That gives a theoretical maximum frequency response up to 86 kHz. In practice it will be lower, probably much lower. Given that human hearing goes up to around 20 kHz max, many sound cards purposefully filter out ultrasound so as to redu...

Re: Question about frequency

The maximum audio frequency is half the sample rate (known as the " Nyquist frequency "). To handle the full audio range (up to 20 kHz / 20,000 Hz), the sample rate must be at least 40 kHz (40,000 Hz). In practice, the sample rate needs to be a little higher, which is why the sample rate f...

Re: Can't paste text to existing label, 17-jan-17 build

I've got a workaround for you Dick.
Copy some audio first (any audio will do, even empty space). Now you can copy and paste text into existing labels.

Re: Can't paste text to existing label, 17-jan-17 build

Moved to the feedback board. Ctrl-v does not paste the clipboard text into the label. Paste Text to New Label still works. Same here on Linux. I observed this problem using the 08-feb-17 build (Audacity 2.1.3) and have found that it first appears in the 17-jan-17 build. Thanks for the helpful detail.

Re: Making a audio file from timing data in spreadsheet

If you can convert (export) your spreadsheet as a list of space separated numbers, then running this code in the Nyquist Prompt may do the trick: ;version 4 ;control tlist "List of numbers" string "" "1 2.5 3 5" ;control dur "One whole number as" float "s...

Re: Problem exporting music

If you zoom in close on the first track (20170127) you will see that the lower (right) channel is upside down from the upper (left) channel: firsttrack024.png In the next track (20170108) the voice is only present in the upper (left) channel and the lower (right) channel contains music only: firsttr...

Re: Audacity "connects the dots" when you zoom in

Unfortunately you've broken something and created a bug. "Zoom to Fit" (Ctrl+E) no longer works reliably. Example: With default preferences, generate 10 second sine wave. From the selection Toolbar, select from 0 to 437 samples. Zoom to fit. Depending on the window size, the selection prob...
