It only scans the first 10 seconds, because otherwise, it would have to be enabled at all times, and would only start to take effect on tracks the moment the first audio packet is discovered.
would be nice if 7zip jist automatically did this kind of like winzip does with the zipx format
The only thing hard coded into the encoder and decoder is the resampling quality, which is set at 5. I have made custom builds with this number changed to 10. I don't think the developers will change this behavior soon as they think that 5 is enough, but still internally at the code, it can go up to 10.Any chance of getting a 32-bit build of this package?
