**** BEGIN LOGGING AT Wed Feb 20 02:59:58 2013 Feb 20 08:27:21 if the gta02 touchscreen tends to jump to upper left corner does this mean that something is disconnected or shorted? Feb 20 08:36:13 radekp: moreover some of the A6 (iirc) versions have useless caps in the earpiece path, and others do not and it's impossible to tell without testing the sound level or looking at the board. Feb 20 08:37:38 PaulFertser: hi, ahh oki, so there cant be one alsa state for all Freerunners right? Feb 20 08:39:32 radekp: one true alsa state is impossible, yes. Even dumb phones allow to adjust earpiece volume during the call to accomodate for varying conditions. Feb 20 08:39:50 PaulFertser: oki, thanks! Feb 20 08:40:50 radekp: but gta02 has another additional uncool odditie: the more you ramp up earpiece volume, the more echo the other side gets :/ Feb 20 08:56:33 PaulFertser: yup, but i guess this is not gta02 specific Feb 20 08:57:19 radekp: probably some more popular devices have a better case though. Feb 20 08:58:32 PaulFertser: yup, my wife has a small sony ericcson phone - so the earpiece must be very close to mic and she has insane loud volume, but no echo Feb 20 08:58:38 PaulFertser: so i wonder how they do it... Feb 20 09:00:07 radekp: without compromising sound quality too, and we use %N187 and yet sometimes there's echo. Yes, really strange indeed. Feb 20 09:00:22 PaulFertser: on GTA04 i tried speex AEC when i was doing SW voice routing, but the results vere quite poor compared - just a bit louder volume and echo was there back... Feb 20 09:02:27 radekp: i wonder if placing some rubber between the upper case panel and the main case would help. Feb 20 09:03:57 PaulFertser: hmm it can be IMO quite easily measure - by recording the sound before and after and comparing the results in some audio visualizing program Feb 20 09:05:50 PaulFertser: but IMO good AEC can do better results... Feb 20 09:09:47 radekp: it's supposed to be inside the calypso as it has DSP and smart guys working on its firmware Feb 20 09:11:25 PaulFertser: i think the AEC in GTA04 modem is also good, i just tried with earpiece and it works ok, no echo at all Feb 20 09:13:23 PaulFertser: only problem i have is that one of my friends complains that he hears me bad - i know it's because of his crippled Nokia, because when i tried to use his phone i heard nearly nothing Feb 20 09:13:45 PaulFertser: so i tried raising MIC volume on GTA04, but then the sounds was quite noisy...
