Livares Labs Project : The Remote Sound Recording System (RS²)

At its early stages of sound recording technology, the industry men hauled their recording equipment weighing nearly half a ton on carts to record the sounds of remote areas like forest. Now as the technology has advanced a lot , we are introducing a remote sound recorder at a quality matching the best and that can be held in the palm of your hand. The System is capable of recording sound from the surrounded remote area at custom intervals and duration with / out any manual intervention.The Recordings are then formatted and stored properly with their time-stamps and are uploaded to storage servers.

INTRODUCTION


The aim of our project is to develop a Remote Sound Recording System with a lower power consumption but also maintaining all the quality attributes.
At this modern era sound/voice recorders have become cheaper and better as the time has made the men and his technology sharper. At its early stages of sound recording technology, the industry men hauled their recording equipment weighing nearly half a ton on carts to record the sounds of remote areas like forest. Now as the technology has advanced a lot ,  we are introducing a remote sound recorder at a quality matching the best and that can be held in the palm of your hand..

Rineez Ahmed - Principal Designer, Livares Labs




Main Components of the system

Raspberry Pi® + Wolfson Audio Card
Microcontroller
RTC Module
USBMODEM



Goal Formulation


The proposed system should at least meet the following goals


  1. Low Power Consumption
  2. Whole System should be compact
  3. Weather Proof
  4. Customizable
  5. Cheaper

Additional Goals

“Save Power No more mechanics !” -  The whole system is designed with the aim to reduce the power consumption , so we haven't used any high power devices like relay or etc ….

“Connect only when required” -  We have also made care to reduce the internet data usage  , by perfectly scheduling the internet connectivity

System Overviewed

As we have said our Remote Sound Recording System has certain goals on quality,size and power.To maintain all our goals we sought in search of a processor that can make up our goals , which ended up  quickly with a result pointing to Raspberry Pi®.
Thus  Raspberry Pi®  became the  Core of our system .  Raspberry Pi®  is a  “ Credit-Card-Sized Computer” which is opensource, brilliant , tiny and brave enough to hold and completely manipulate our system at its best.
You can find more about Raspberry Pi®  here What’s a Raspberry Pi?

Problem Formulation
As from Raspberry Pi®  the system is to be started , on the stage of feasibility study problems began to start we have listed the main hurdles one by one

ther thought , we just programmed to make our RTC module updated from Internet -Time-Servers(Read on NTP here http://www.ntp.org/ )

4.The Custom automated time began to reset when the MC Resets

Soln: This is because the MC circuit have a Volatile memory , this time we are forced from adopting a newer circuit , but we  exploited the 56 bytes of NV SRAM that is available in our RTC module , as we said earlier since our whole system is interlinked now  it haven’t been another barrier.

5.The construction of the waterproof enclosure for our system.

Soln:  This time we got in search of a “wifi antenna box” that can fit our need.After having one with us we ported it perfectly to match our needs.

System Functioning

In short the system works as follows ,
The sound from the surrounding get captured by a high sensitive mic which get boosted and converted to electronic digital data by the Wolfson’s sound processor which get stored  and uploaded to the storage server by the Raspberry Pi® .
