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

Rendering the samples with uneven spacing is inherently misrepresentative of the underlying data. In the absence of sub-pixel rendering I don't see that we can get away from that "misrepresentation". What should we do if a sample value (amplitude) lies on a boundary between two pixels? Th...

No offence intended or taken - just checking that we're both clear.

Re: wavpack (export) support?

On further digging it seems this isn't going to work. The "external program" option uses STDIN which is limited to 16-bit. It looks like the only option available for 32-bit float wavpack is to export from Audacity as 32-bit float WAV (or AIFF) and then use another application (such as the...

Re: Left and Right channel recording

Is there a particular reason I would want/need to record a voice on both the Left and Right Channels? Is mono recording a "standard" practice? The general rule is, if you are recording a mono source (such as a mono microphone), record it into a mono track. Note that if for some reason you...

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

I backed up (Ctrl-z) to where I had the original project plus just the extra empty audio track. Then I selected the 42 minute clip, copied and pasted it to the empty track. If there is audio on the clipboard, pasting text into labels will work. The number of tracks is a red herring. The problem can...

Re: MP3 compression

Does MP3 compression work in similar principle to JPEG compression? In other words, editing a file and then re-saving further compresses the file losing even more data? Yes. MP3 is a "lossy compression" format. As with JPG, the damage can be minimised by choosing a low compression (bigger...

Re: Why is WinXP better at running Audacity than Xubuntu?

Yes I saw that, but my point was that lightweight derivatives of Ubuntu are not (in my experience with a 1 GHz / 1 GB RAM notebook) that much lighter On my machine, Xubuntu is certainly lighter than vanilla Ubuntu, but Debian with Xfce is noticeably "lighter" again. Also I find Lxde notic...

Re: wavpack (export) support?

If you have a command-line Wavepack encoder installed, then you could use Audacity's "Exporting to an External Program" option: http://manual.audacityteam.org/man/expo ... ogram.html

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

You could probably mitigate this by .... "I" could do ...? Oh no no no. ;) I wouldn't dream of interfering with your project. I'm just offering feedback. I've got plenty of my own work to do. Still, I'd argue that this could be correct behavior if the user wanted equally spaced samples. O...

Re: wavpack (export) support?

Depending on your build of FFmpeg, it may be possible to export as wavepack by using "Custom FFmpeg Export Options". See: http://manual.audacityteam.org/man/custom_ffmpeg_export_options.html I'm using the default Debian 8 version of FFmpeg, and wavepack export is not supported here. You ma...
