Podcasting Equipment / Gear:
To get started you will need a computer with broadband Internet access, a mic and headphones.


You can record a podcast with the built-in microphone of your laptop or some external headset microphone. This way the sound quality will not be the greatest. If you want the best sound quality you will want get a nice studio quality dynamic microphone. If you plan to conduct interviews with two or more people using one microphone, an omnidirectional mic would be needed. The Blue Yeti professional is an all-purpose microphone that will do the job and would be in a podcaster’s budget. Podcasters who plan to record in the field or record musical performances might have different mic requirements.

Sound Card
Simple podcasts can record directly into the computer’s sound card, especially if you only use one microphone. This may require some adapters to match the plug on the mic to the input on the sound card.
The soundcard itself is another important consideration. Be aware some low-quality sound cards introduce a lot of extra signal noise due to electrical interference, or distort sounds at high signal levels. A lot of soundcards in the market offer additional inputs for simultaneous multi-track recording with specific software or mixers.

Audio Software
Software is an important element for recording for Beginners. I recommend using Audacity or any other audio software of your choice which allows you to set the proper recording levels, record the podcast and save it in a useful audio format. You sometimes need to save the audio in MP3 or wav, etc… You can also edit the podcast using software for mistake in recording or cut a single recording into multiple or attach together segments recorded at different times and places. Software will also help you manipulate the quality of the sound by using equalization filters, effects, noise reduction and volume adjustments.

Unboxing the Blue Yeti Microphone

I bought a new Blue Yeti Professional Microphone in November. It a nice piece of equipment for someone in eLearning profession like me. I have been using it to record voice overs for my eLearning modules. Previously i had been using a HP headset to record voice and also for my podcasts. The cost is dear compared to other mics available in the market, but Yeti gives the best settings and the output.

It has a built in tri-capsule array which are 14mm tuned condenser capsules.  The base of the Microphone has soft rubber to give grip and reduce noise.  The base is also very convenient for managing USB, microphone and headset cables. The stand and the main mic units are connected by knobs on both sides, which can be used to clamp pop filter. The bottom of the microphone has a standard threaded mic stand mount, USB mini jack and a headphone output with an amplifier supported by volume control.

The front of the Microphone has the Yeti logo, Mute button and a master volume control. The back side of the mic has two controls, Gain control and pattern selection control. You can select one of the patterns cardioid, bidirectional, omnidirectional & stereo as it suits your needs.

Watch me unbox the new Blue Yeti Pro:

Yeti features only digital output, which is set to 16 bit/48 kHz. The only drawback is that this sample rate is not user-definable.

I have recorded a lot voice-overs for my elearning modules i create. So far all is good and the audio quality is better than before (recoding with an HP headset). One thing i noticed is that, Yeti picks up very minute noise in the room, so i reduce the Gain while recording. I don’t have a professional recording studio, but my recordings with Yeti are of studio quality. :)

Vodafone Service Fail!…..

Indian has one of world’s largest mobile subscriber base. New connections are adding at a very fast rate, something around 192. 56 million in 2010. This is a whopping 49% increase compared to 2009.

The total number of telephone connections in India now stands at 621.28 million at the end of 2009 financial year. The sad thing is that the overall teledensity stands at 53%. TRAI Aual report 2009-10

The call rates vary anything between Rs 0.30 to Rs 1 (0.09 cents US). How can the mobile operators charge you so less and still make a fortune. They compromise on service quality.

After being with Vodafone for 2 years, I had to move to Idea Cellular. I had to battle with the Vodafone Customer Service regarding my bill. Vodafone wrongly billed me during December 2010 and May 2011. I had to call the Vodafone accounts every month to correct the errors in the billing, most of them were corrected. Vodafone activated ISD packages and Vodafone Live TV packages, which were never requested by me. During the month of May they even charged me 1000 rupees for internet usage. Their connectivity is also a bit crappy in Hitec city, Hyderabad. Mobile internet also had problems switching between towers. I was fed up with their service and decided to port out to Idea Cellular in August, to which Vodafone refused to let me go. Vodafone held up my request for porting numerous times and finally had to walk into their store and request them to let me move out of Vodafone.
Finally on 25th December moved to Idea Cellular. For some reason my HTC Wildfire shows Vodafone IN as the Signal name. Even after removing the SIM card and turning on the phone it still the same. Mobile companies spend billions on acquiring 3G and 4G licenses, but show very less interest in improving customer satisfaction. I would have stayed with Vodafone if they have showed little interest in resolving my billing and connectivity issues.

Can lightening Kill us?



A few days back there was news of twelve people dead after struck by lightening. At least it is not in one particular location, but spread across the state of Andhra Pradesh in India. It is very sad news for the families, near and dear. But the question is can lightening really kill us? Of Course it can… Lightening is nothing but an atmospheric electrostatic discharge which can travel at speeds of 220,000 km/h.

A few weeks back I was watching an YouTube video (See below) when a man was hit by lightening twice and still gets up and walks away. Lightnings when in the earths atmosphere, its temperature can reach about 30,000 °C. The person in the video might have had some kind of resistance towards to electric and magnetic energy. Anyway i can’t imagine myself there.
