I haven't got any clue about software access of FR's MCU's sound port i.e,
IIS port. Please provide me with help regarding this.

Thanks!

Hi Arslan,

A while ago i tried to write a software modem to communicate between 2
freerunners.
One of the things that went wrong was a 90 degree phase shift in the
audio signal.
So when you write audio software, please keep in mind that it might get
phase shiffted.

Kind regards,
Ed

Simple recording and playback of recorded sounds can be done but, can
anyone give me some clue if it has enough
processing power to do real time voice processing and transmitting
processed voice at the same time. And please, if anybody has any code
related to voice manipulations on this phone or in particular real time
voice processing while transmitting through gsm, share it. It'll be very
nice of you.

@Dave... Encrypting gsm is legal in our country, and as far as i think
encryption shouldn't be illegal coz voice/data is your private property so
protecting it further shouldn't be a problem with anybody as long as it
doesn't affects their systems.

There was already somebody who developed a program to do encrypted GSM calls 
with two FR. But i don't remeber who it was.

IIRC there was a program which recorded phone call if this is what you need. I 
dont know how it's done on GTA02 but on GTA04 phone modem is just another 
sound card which can be used by alsa programs. E.g. you can play mp3 instead

Information about linux drivers for voice in neofreerunner........

2012-01-17 Thread Arslan Abbasi 
Hi,

I'm a development engineer at a firm and I'm working on a project of
encrypted voice communication using gsm. So, with the open functionality
provided by NeoFreeRunner, I opted for this phone. Currently i'm unable to
find any help related with real time voice processing and my target kinda
desires it.

I want to know if there are any embedded linux drivers available for
accessing the IIS port of it's MCU. And can i get any direction about how
to manipulate voice in it's application processor if there's any sample
code available.

Thanks & With Regards,
Arslan Mumtaz Abbasi.
