#4254 closed defect (fixed)
Measure's FFT mode broken
| Reported by: | greenfeld | Owned by: | walter |
|---|---|---|---|
| Priority: | Normal | Milestone: | |
| Component: | Measure | Version: | 0.97.x |
| Severity: | Major | Keywords: | regression |
| Cc: | godiard, dsd | Distribution/OS: | OLPC |
| Bug Status: | Unconfirmed |
Description
- Start Measure and verify you can see audio on the oscilloscope.
- Click on the Sine Wave in the top menu to switch to FFT (frequency graphing) mode. Nothing will be displayed.
- Clicking through various measurement modes eventually will restore the original Sine wave, but going back directly does not seem to be possible.
Seen in OLPC 13.1.0 os12/Measure-42 on XO-1.5 and XO-1.75

That is being tracked in http://dev.laptop.org/ticket/12398 so I'll close this ticket. Thanks.

The problem seems to be a change in the behavior of the numpy multiply function. Looking into it.
