Media links December 9, 2014

In honor of knocking out yet another final project for this semester I present some media links. I've got two finals down and one to go. This last one might be the most fun one of them all, since it's a sound project.

Dear Podcasters - Chris Brogan

Dear podcaster: I’m really glad that you were kind enough to invite me to be a guest on your show. It means a lot that you think my ideas will be of value to the community you serve. I really want to share a few things with you before we get started.

Star Wars: X-Wing Special Edition - gog

I remember playing this game for hours. If someone is looking for a Christmas gift idea for me, this would be a pretty good one.

This Artist's Images Integrate Code From Malware Like Stuxnet and Flame - Andy Greenberg - WIRED

Hoff creates his malware-glitched works, which have all already been sold, by dropping digital paintings into a hex editor that converts it to text. Then he intersperses randomly chosen chunks of code from malware files, and reconstitutes the data as an image file. The code corrupts the image in unexpected ways, adding chromatic streaks, blotches, and static. In two of the images, Hoff used code from the NSA-created software Stuxnet, built to destroy centrifuges at Iranian nuclear facilities. The other 14 images use code from Flame, which Hoff calls by its alternate name Skywiper, an older NSA-created spyware program.

Podcasting tips: editing and processing

Previously, I talked about equipment tips for podcasting. In this post I want to give some basic tips on editing and processing audio files. These are some of the things I’ve learned along the way:

Editing

Always edit from the end of the audio to the beginning, especially if you have time markers for editing. If you start at the beginning and edit to the end you'll change any time markers you set.

Truncate silence is a wonderful option in audacity. Effect -> Truncate Silence and define the amount of space allowed between audio waves. Once the process is started it will remove all the dead air in the audio file. Again, if editing markers are set make sure those are taken care of before hitting truncate silence.

Setting markers. In audacity it’s CTRL + M. It will set a mark during recording for you to go back to later.

Processing

Levelator is great for processing audio: http://web.archive.org/web/20130729204551id_/http://www.conversationsnetwork.org/levelator/

Export the audio as a wave and drop it in the levelator box and it will clean up and level everything in the audio.

Once that's done put the wav file in iTunes and convert it to an MP3 file. Here on instructions on how to set that in iTunes: http://support.apple.com/kb/ht1550

iTunes does a good job of converting wav files to MP3s and is the simplest method I know.

Podcasting tips: equipment

was recently asked for some tips on podcasting via email and I decided it would be a good idea to throw them up my website here for anyone else interested. Podcasting can be as simple as recording from your phone and putting it online or as complicated as getting a $300 microphone, a mixer and professional software. How you podcast is based on how much effort you plan to put into it and how much you’re willing to spend. I would suggest starting simple and cheap and then build on that as you get more into it.

Below you’ll find podcasting tips for a single person setup that costs about $50. The person I was giving tips to was for equipment and software ONLY. If you’re planning on podcasting you’ll need to consider hosting options for your audio files.

Get Audacity, a microphone and a headset or earphones.

Audacity is a really good free audio editing software: http://audacity.sourceforge.net/

It's what I use for my podcasts and fairly intuitive to learn.

Just about any mic available will work for recording a voice, whether it's a headset, a built-in laptop microphone or even a phone if it has recording capabilities. Your quality mileage will vary depending on how much is spent on the microphone.

I would recommend audacity, any headset or earphones and an ATR2100 USB mic: http://www.amazon.com/Audio-Technica-ATR2100-USB-Cardioid-Dynamic-Microphone/dp/B004QJOZS4

It's under $50 bucks but will improve the quality of the audio significantly and because it's USB all you have to do is plug it into the computer and go. And because it has an XLR connection it can also be hooked up to other more advanced audio devices. It's the same microphone David, Sean and I use for Crawfish Boxes: Astros Baseball Show. I would also recommend some sort of screen for the microphone. A cheap option would be a simple screen for the microphone. http://www.amazon.com/Stage-Foam-Ball-Type-Windscreen-Black/dp/B0002GXF8Q/ref=sr_1_2?s=musical-instruments&ie=UTF8&qid=1406421196&sr=1-2&keywords=microphone+windscreen

A more expensive option would be to get a desktop mic stand ($15) and a pop filter ($10-15).

$3 is about the cheapest you can go and again will improve the quality of the audio. Something I take very seriously if you hadn’t noticed.

Gaming headset also have decent microphones, but won’t be better than the ATR2100.

Examples:

12th episode:

This is me with a gaming headset.

127th episode:

This is me with the ATR2100.

Now I have refined my editing and audio processing techniques, but this still should give you a good idea on the quality difference in microphones.
