Steps To Reproduce:	1. Set preferences->Devices->Track-Shift-After-Record to -30000 (yes, that is 30,000 milliseconds or in other words, 30 seconds). 2. Set preferences->Devices->Recording->Channels to 2 (Stereo). 3. Generate tone. (so there is a track to shift relative to) 3. Shift+Record to new track (not append record) for 5s and stop. You will get two warnings.

Comment 1 Peter Sampson 2017-08-07 08:18:43 UTC

Is this still valid?

Comment 2 James Crook 2017-08-16 10:53:09 UTC

DEVEL - FIX MADE
https://github.com/audacity/audacity/commit/296ba29a78386721b2061f0b444eacc8cef50a10

*** STEPS UPDATED ***

Steps were just ???.  With the correct updated steps, this bug was still valid (but very minor).  And it was easy to fix too.

(In reply to James Crook from comment #2)
Testing on W10 audacity-win-e984211-2.2.0-alpha-21aug17
and on macOS Sierra 10.12.6 e984211 21Aug17

With both of these following the steps to reproduce.

1) With Overdub turned off I get no error messages

2) With Overdub turned on I get a single error message on both platforms:
"Latency Correction setting has caused the recorded audio to be hidden before zero.
Audacity has brought it back to start at zero.
You may have to use the Time Shift Toll (<---> or F5) to drag the track back to the right place"

On both platforms with usecase-2 tha newly recorded audio does indeed appear to be time-shifted right a little about .13 of a second on W10 and about .38 of a second on Mac.

I have no idea what correct expected behavior should be - or if this bug is fixed.

Mac 10.11.4 Audacity 2.2.0-alpha Aug 28
Only one "before zero" warning so this is fixed.

Works for me too.
Resolved Fixed.
