You edit audio waveforms in Audacity in much the same way as you would edit text in a word-processing document. Step 5: Create a 10-second clip from your audio On Windows, dragging the file to the Audacity icon in the Taskbar will either switch the window to Audacity if it is running (from where you can drag the file in), or if Audacity is closed, give the option to launch Audacity with the file imported.

On Mac and Linux you can drag the file to the Audacity icon in the Dock or Taskbar respectively to import the file into Audacity.On Windows and Mac you can also drag to Audacity's icon in a file manager application.Specific dragging behavior according to platform: dragging the audio file to the Audacity icon on the Desktop.dragging the audio file into the Audacity window.uploads/default/original/3X/fd34c88563051c9955c106255b9be725822f.First launch Audacity, then import an audio file by selecting File > Import > Audio.Ī quicker method is to just drag and drop the file as in the following examples:

Unfortunately, I don’t know how to figure out which decoder audacity uses in each case. My hypothesis is that in the two cases audacity uses different mp3 decoders, and the default/fallback one is buggy. I’m also attaching the difference between the libraries that the two versions of audacity are linked against (“+” are present only in the “good” version', “-” are present only in the “bad” version). I’m attaching four files: the original mp3, decodings done with both versions of Audacity, and the (amplified) difference between them. Both versions are built from the Audacity-2.2.2 git tag.

On the other hand, when I use audacity built on the same machine but with the audacity-freeworld patches (that make audacity link against various audio libraries), there’s no noise. I noticed something interesting: when I use audacity built from git (using the instructions from the INSTALL file), there’s some extra noise when reading mp3 files.
