Bug#450609: ams: spectrum displays bogus values
Package: ams
Version: 1.8.7-5
Severity: normal
Tags: patch
The spectrum module displays bogus values. To reproduce, just
connect any sound stream to the module and watch the displayed
spectrum.
This is due to a type mismatch. While it uses the single-precision
version of the library (Makefile says: "ams: [...] -lsrfftw
-lsfftw"), it includes headers for the double-precision version.
This patch fixes the problem (tested).
