"Ignore blank space" Preference fails on Export Multiple based on "Tracks"
Last modified: 2020-04-16 19:06:30 UTC
Tested on Linux only. According to the manual: "Ignore blank space at the beginning: This is off by default, so Audacity will treat any leading blank space as silence when exporting audio and will place the appropriate amount of silence at the beginning of the exported audio file. You can check this option if you do not wish to have such silence added. A use case for turning this "on" is track-based multiple export ..." The clear implication is that this option "should" work with Export Multiple based on tracks. The obvious use case for why this behaviour is needed is when exporting tracks from a multi-track project for use in a DAW.
Fails on W10 too - so assume all platforms Normal Export Audio does pad properly with the leading silence when that option is checked "off" (default setting). Raising this to P2 as we really should be fixing this for 2.4.0
This also fails if you work with a single track and export multiple by tracks, but succeeds if yo work with a label driven multiple export. 1) ensure "Ignore blank space at the beginning" is set to "off" 2) get some audio 3) Time shift it rightwards 4) File> Export Multiple 5) set it to export based on "Tracks" 6) Import the exported track 7) Observe: the audio has *not* been padded with the leading silence 8) Add a label at T=0 9) File> Export Multiple 10) set it to export based on "Labels" 11) Import the exported track 12) Observe: the leading silence is present (as expected)

(In reply to Leland Lucius from comment #3) Tested on W10 with Audacity 2.4.0 9f51770 This now works properly on both platforms 1) Default settings The tracks are exported with proper leading silence 2) turn on export pref for "Ignore blank space at the beginning" The tracks are exported without leading silence, starting at T-0 3) 2) turn off export pref for "Ignore blank space at the beginning" The tracks are exported with proper leading silence

Tests OK on Linux.
