Stereo to mono
- Thread starter Fishnmaine
- Start date
Quoting ak 1234 from another thread:
"v1.3 was a fix to address the "mono to stereo" problem that some people had. The headphones are not really changing from mono to stereo, the phase of the audio waveforms are changing (result of having stereo and microprocessor timing). So, if somebody is sending in their detector for an audio fix, both detector AND headphones need to be sent in to get the benefits of the fix. I think that is what HOTROCKS is referring to. The headphones do not need to be upgraded to work with new versions of the detector software, they just won't have that fix in them."

From another forum where Carl said;
It's not really a stereo/mono issue, but rather an audio phase rotation. Normally, V3 produces the same sound in both ears, what most people would call mono since there in no L/R difference*. When you hear the sound go "stereo" (a sorta surround-sound effect) you're still getting the same audio in both ears, but with a phase rotation that plays a little mind-trick on you.
Our latest software rev fixes this, so that there is no phase rotation and, therefore, you would not hear the funky "stereo" effect.

*V3 uses L/R only in the balance settings, and in the audio effects (end-of-range beep).

Thanks rcasio44 & flapjack ...I asked the same question there to...to which he replied to.........I wonder if this is something that has to be addressed right away before something happens or can I just run it it like that?....I'll deal with it for now and in the winter I'll send it in for the upgrade to 1.3.
