Sharing an observation..... >From experimentation it appears that the "left" mic channel has side information and the "right" has mono (middle). Something like Chan1=L-R Chan2=L+R.
If this were reversed at least most applications would get the sum of the two microphones (i.e. mono). As things stand, when apps use the first mic channel they just get the difference (side) which is usually of no use. To confirm this I moved around making noise, then using audacity I split the stereo sample into two mono samples, I'll call them 1 and 2... inverted 1 to make !1, then with a bit of fiddling made a pair of samples (1+2) and (!1+2), joined them as stereo left and right and got what I'd have had if the mics had been straight stereo. If anyone here has audacity on their 901 can they confirm that the right channel appears to be the sum of the mics, and the left is the difference? -- Eee PC internal microphone inverts noise cancellation https://bugs.launchpad.net/bugs/331130 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
