#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


  1. Start Measure and verify you can see audio on the oscilloscope.
  2. Click on the Sine Wave in the top menu to switch to FFT (frequency graphing) mode. Nothing will be displayed.
  3. 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

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

using astype seems to fix the problem... pushing a patch

Will be included in next release

This likely needs a release for 13.1.0.
