So I just did a quick test on 2001 Space Odyssey DVD 5.1, converting it to 5.1 .w64. The first wave is the central channel converted via ffmpeg without drc_scale command aplied. The second one is ffmpeg with drc_scale set to 0. The third one is a straight forward convertion with UsEac3to130, no other commands. Looks like eac3to applies drc to 0 automatically.

So if importing ac3 into audacity (which uses ffmpeg), would it be better to manually convert the track first with the drc_scale command to better preserver the full dr? Thanks given by: dvdmike

What use is an okay codec to me if it's just impossible for me to play it back without major distortions or having to transcode the audio every time I want to watch something with it?

Nice job! That mirrors my own experience in terms of how the waveform looks. Makes sense that eac3to can do it properly I guess. I'm just more used to ffmpeg personally. Thanks given by: allldu

Idk if Dialnorm is the correct term for what I mean, but ac-3 definitely seems to have massive issues with playing back at full dynamic range. I don't think it's necessarily an issue with the format, more with the playback software I've used. It's almost impossible to get a proper playback at full dynamic range in something like VLC or MPC-HC, last I checked. My 43" Hisense Smart TV doesn't apply DRC to AC-3 tracks when I play files directly from the built in media player and output it via SPDIF to my HT receiver.

I just discovered this thread.
I wanted to buy the Matrix 4k, and it sucks now to know that it doesn't include the original audio. Do we know anything about Matrix revolutions and Matrix reloaded? |
