Bug#514558: audacity: incorrect decibel scale

Package: audacity
Version: 1.3.5-2
Severity: normal
A tone generated at 10 percent of the PCM range should be shown as -10 decibels,
if my understanding is correct. Audacity's "Waveform (dB)" view shows it as -20
instead. The "Amplify" effect also suggests amplifying it 20 decibels to
maximize the volume. Is this wrong, or am I missing something?
