SPL (dB)(sound pressure Level) Meter for WM6 - 8525, TyTN, MDA Vario II, JasJam General

I have a Hermes 100 (8525) I am in Technical Producitons as an engineer. I am constantly needing various testers and tools to do my job.
Is there any software that can use the mic on my phone as a SPL meter or spectrum analyzer? Maybe there's something I could plug into the usb mini and help me do this? Or bluetooth? IR? ideas?

I am not sure if there is something you described - you have bigger chance somebody will notice your post in General or Development and Hacking forum. Try to post your question in one of these, maybe somebody will have some info.

hi, first thread: what kind of couple-capacitive needed?

hi,
this is my first thread here, sorry for my bad english - but i'll try my best.
i want to connect my xda2 with the 22 pin-connector for mp3 in my car.
in your conectors-page is a note:
Audio needs to be capacitively coupled in, any DC bias seems to inhibit audio
i want to ask, what c is needed here? (how many farrad, what kind of C)?
please can you give me some tipps?
is there anyone who has built such a connection? is this a good way to connect the xda2 through the car-radio, or is it better to connect via audio-jack?
my opinion: i found it very uncomfortable to connect first the audio-connector (specially in the dark), and i would be very happy if it works through the 22-pin connector.
please please...gimme a tipp.
or did anyone connect the xda2 and car-stereo without couple-c?
c'mon please, a little answer and i'll be happy.
anyone must have finished a 22pol-connector by himself, or am i wrong?
ty
frustrated...(bad first experience)...
you may be asking too much of a technical question for the cuurent people who watch this board.. i get the impression that the xda-developers site started out with a lot of smart people reverse engineering and dismantling the devices, but its now become more of a software tech support site than a hardcore HTC guru site..
Hi there sorry to hear you have had a bad experience.
as stated xda-dev no longer is as good as it used to be.
i had a quick look at the diagram and from what i can see you should not need capacitors at all.
from what i can see if you connect up pins 3 and 4 to the necessary inputs on your stereo the sound is fine.
a problem i can see however is that to get output on these pins you need to attach pin 19 to ground with a 10k resistor...but this will also redirect the microphone so you wont be able to use it as a phone whilst you have it plugged in unless you also build in a microphone (mind you this should be pretty easy if you wish to do it).
hope that helps

builtin mic is usless for precise measurments.
There is a lot of soft for this... try Googling... ex.: http://classic.pocketgear.com/software_detail.asp?id=9071&associateid=302 but there are some free ones as well... It works fine with an external mic
Did you test RTA?

Click to expand...
Click to collapse
There is a software called RTA that you can download from handango, the trial only works for a minute, then you have to restart it. I believe that you´ll need a real dbA/dBC to compare and calibrate your Pocket on first use.

Radio playback

Hi all
Does anyone know of a tweak to allow radio to be played without inserting a wired headset, I often listen to music via bluetooth and would like the option of radio as well, thanks in advance.
By the way, I did search the forum before posting this as I know you guys have certain protocols in place.
Cheers.
try this and see if it works
Change the following registry : HKLM\System\State\Hardware\Headset from 0 to 1
hi, thanks for the reply.
I don't have my headset with me today but after I changed the reg the radio still would not play directly through the phone, what exactly should this reg edit do?
it should make the phone think that a headset is plugged in..havent tested it myself to be honest but it should work..however whether or not you will have a signal from the radio is another story
Dude, ther is no use for this... Even if you would get the device to start the radio without the headset pluged in, there would be no sound since the headset is the antenna...
So it would be like you are watching tv without cable... no reception!
There must be at least something in the mini usb plug. I found that it works at least a little bit when plugging in this thing only and playing the sound over the internal speaker though reception is poor at best.

Good luck!
There is some use to it... although the wire is the antenna the phone will act as an antenna also so you will recieve some signal it just won't be as strong.
Without fully testing there is no way of telling how good the signal would be, surely a phone that can pick up a GPS signal and a mobile signal should be capable of also picking up a radio frequency?
no, its not possible:

ok, I get the message. Thanks for all your help.
OT - I searched "Radio without Headset" accross this forum and had no hits.
I noticed that innocent people get shot down when they don't search before posting a question, how are they supposed to get decent results with a search engine that doesn't work properly. - Great site guys, the people here really know there stuff but perhaps go a little easier on people who search to no avail before posting. You don't have to reply to the post and if you do wouldn't it be best to simply give the answer or direct them to another post, up to you but it doesn't help anyone to just put - SEARCH THE FORUM or RTFM (a new one on me!)
Hope you see the point of this post, I am simply giving my opinion as an outsider who has just purchased a Diamond and I'm just getting into mods and tweaks!
p.s. Loving the GPS cycle computer. Best app by far!
GSM is in a very much higher frequency band, so it uses a very much smaller antenna than you would need for your radio. This is two very different systems. It will not work without an antenna

[Help] Use Speaker when Headphones are Plugged In

I posted this on the Raphael forum but got no answer, and as this question probably applies to several devices I thought I might ask the knowledgeable folk who stop by here too:
I'm trying to find a way to have sound coming from the speaker even when headphones are plugged in (same as the option in the FM Radio application). I was hoping it would be as simple as changing a registry value, but I've compared the registry with the setting in the FM radio enabled and disabled, and found no difference in the registry.
Any ideas how this can be done? I can program in vb.net for mobile devices if the solution needs coding.
Cheers
Rowan
Bump.
Any suggestions at all anyone?

Modding the X1 hardware for tv-out :)

Hey guys!
I know this has been up before, and I've read pretty much every thread regarding the non-existent TV-Out function on X1. But it has made me curious enought to want to attempt a mod if such a thing is possible.
What I understand the X1 has the hardware for TV-Out, but not the functionality implemented. So somewhere along the hardware line, the function is disabled on purpose/not enabled. Chances are, HTC saved in a few cents on the connector itself for example, and that's where the missing hardware line is
Now, most people say the X1 shares the hardware with X2, I'd like to know to what extent and if someone has pictures of an opened X2 to share, it would help out alot. Specially pictures around the 3,5mm connector and connections around it, but also the pictures of the entire mainboard.
If I can find an easy enough way to resolder some new connector/parts, I will def. do so, with full documentation over how to do it. I say harder things have been accomplished before. It all comes down to the differences/similarities in X1/X2 hardware.
PS. I might be taking water over my head here, but I'm one of those guys who got his X1 on day 1, trusting the words of SE about TV-Out, DLNA etc etc. And if there is a 10% chance to achieve this, I will try it.
Thanks for any help in advance
/Z
Come on dude you can do it :O
And if it worked i'll donate you for sure
Support you ^_^
uuh..
Hey Zoonie,
i wouldn't say it's impossible, but it's some hard piece of reverse engineering the hardware of X1.
From my point of view somebody has to rip off the MPU and the PM chip and trace the dedicated pins/signals to find out if there's a connection to these signals somewhere on the mainboard. That's the first part
Once you know how to attach some hardware to the signals, you'll need some driver code implemented to support TVout on X1
Anyway here's a basic schematic of TVout for MSM7200!
Have fun,
scholbert
Go for it! Love the effort.
Doesn't the touch pro have TV out? I would think it would be better to try to copy that, since it's the same processor and both HTC manufactured.
