HDHR - volume adjustment

[tsitalon1]

Forgive me if I posted this in the wrong section.

WIth my standard tuners, all channels have aprox the same volume. With the HDHR, one of my HD channels has very low volume. It works, just is low in volume requiring that I turn up my surround sound to full power to get have the volume of the other channels.

Is there a way in Sage, or in the HDHR to increase the volume per channel or station?

The problem is that HD programming typically uses AC3 audio, which has a far greater dynamic range than analog cable.

You can use AC3Filter, which has a Dynamic Range Compression (DRC) feature.

Sound through other tuners is fine. There is no way to stipulate which audio decoder to use with the HDHR is there?

It's not the hardware (i.e. HDHR) that's causing this... it's the source material. The show with the quiet audio is AC3 (5.1 channels instead of stereo), and AC3Filter sounds like it has a lower audio level (due to the uncompressed dynamic range of true AC3 5.1 channel audio).

To prove this, go and change the gain or compression (DRC) in AC3Filter and watch the same program... you should be able to level it out.

There are settings within AC3Filter to control which sources utilize it (MPEG2, MPEG4, TS, etc).

If you're using AC3Filter, go into it's options and disable the "Normalize Matrix" option, it seems to significantly overcompensate for the summing of channels when downconverting 5.1 to stereo.

Thanks for the tip did the gain and matrix option off on ac3 filter and sounds as loud as the analog channels
