ReplayGain weird leveling

[dejan]

When I'm using ReplayGain or DynamicReplayGain in ProppFrexx with music tracks (orginal or ripped, flac, wav or mp3) everything is working as expected.
Then I made some voice recordings and ReplayGain or DynamicReplayGain does not work as I thought it would. I even made a test signal (1kHz) at different levels (0, -6, -12, -15.1 and -18dB) with different sample rates (44100, 44000 Hz) and save it as wav and mp3 format files. I was using Adobe Audition and Audacity. The problem is the same and that is:
No matter what sample rate, no matter what format, no matter what type of sound (voice or 1kHz), no matter what software I was using, no matter what floating point was set to, ReplayGain always lower the file by 15dB if the recording is between 0 and -15.1 dB. When recording is -18db ReplayGain do nothing (level stays at -18dB and that is OK). When I turn off the ReplayGain PF plays all the files at their original level and the problem is the same when I change the gain level of ReplayGain from -6dB to -24dB.

Any clues?

What exact ReplayGain mode are you using?
And when you press ALT+2 on a track what ReplayGain and Peak value is shown?

[dejan]

Mode: ReplayGain / Default Replay Gain: -6dB
File 1: test_1kHz_0dB.wav / Tempo=0,00, Gain=1,00, ReplayGain=0,20 (0,99)
File 2: test_1kHz_-18dB.wav / Tempo=0,00, Gain=1,00, ReplayGain=1,57 (0,12)

I don't see Peak level!

The problem is the same if Dynamic ReplayGain is used.

You have given the peak levels already in brackets
But I guess where my error is, it happens when the ReplayGain value is calculated above 1,00.
Here I did apply an algo to prevent clipping of the final replayGain factor, but I just saw a small mistake in there.
I'll fix that in a next update soon!

With regular audio files this however should normally not happen, as most of these file do have a ReplayGain value below 1,00 (or in other words a negative ReplayGain dB value)!

A new v4.0.1.21-beta is available (so please "Check for Beta-Versions...")!

Thank you for you answer. I'll do it later these week and inform you about the results.

Regards.
