CCATP #423 Dave Hamilton Talks Digital vs Analog Headphones

Dave HamiltonI asked Dave Hamilton to come on the show to help us understand the impact of Apple removing the analog headphone jack. I didn’t want to do a big hand wringing about how annoying it might be to replace all of our headphones, rather I asked Dave to come on the show to explain in geeky detail what it means to have analog vs. digital headphones. We start at the beginning talking about how sound is produced in a computer and work our way through sample rates, bit rates and into some of the mechanics of a digital to analog converter (DAC). We also talked about the impact on audio when you use Bluetooth headphones.

Dave and I mentioned a couple of things in our conversation:

Understand the math: Nyquist Frequency
Annoy Children: Frequency Only Kids Can Hear
Add Bluetooth to any headphones: Antec Smartbean Bluetooth Receiver ($11 on Amazon)
Can you hear the difference? ABX Tester for iOS, ABX Tester for OSX

CCATP #421 Chuck Joiner on Apple Watch Fitness and Gear for Video Interviews

Chuck Joiner of the MacVoices podcast joins us to talk about how the simple reminder of the little loops on the Apple Watch Activity app got him to stand up once and hour, do a little exercise and start to feel better. We then move into conversation about how he records his video interviews for shows like CES. He’s a one man band with a cool rig you’ll want to hear about.

CCATP #417 Chris Ashley on the New Hotness from Microsoft

Big chris ashley ccatpIn this week’s show Chris Ashley from the SMR Podcast (smrpodcast.com) joins us to talk about all of the cool new hardware products from Microsoft.

We talk Microsoft Band, Surface Pro 4, Surface Book and the new 950 Windows Phone. We talk about how great it is that Microsoft, Google and Apple now build on each other’s ideas which is only good for us, and how Microsoft makes some amazing tools for the Mac and iOS. It’s a really fun conversation with one of my favorite people.

Chris told me he’d never forgive me if he caught me taking a photo with the iPad Pro…so I took this photo of him on my screen with my iPad!

In the conversation we talk about how Rod Simmons from the SMR podcast brought his Surface Book over to our house and we compared the tablet portion to the iPad Pro. Here’s a photo showing the comparison.

CCATP #416 Antonio Rosario on Black & White Photography

Amrosario instagram page showing b/w photosThis week we’re joined by Antonio Rosario, a professional photographer and instructor based in Brooklyn, NY. He’s also a digital imaging and workflow consultant. In this conversation I attempt to learn the workflow he uses to make his iconic black and white street photography stand out. It takes a while for us to get to that point because we have a lot of fun talking about his progression from the early days of film processing up to today.

We talk about RAW vs JPG and why he actually uses the JPG files most of the time (spoiler, his Fuji X100T does an amazing job of creating great JPGs), we talk about how he uses social media to further his business (spoiler, Instagram for the win).

CCATP #415 Bart Busschots Ponders the Mystery of the Christmas Star

Bart's opening slide Ponderint the Mystery of the Christmas StarBart Busschots takes us on a journey of discovery to try and see if we can determine what celestial body was seen in the sky on the night of Jesus birth in the city of Bethlehem. This discussion is not judgmental or prejudicial, but rather takes us through what we know of history at the time, what we know from the Bible and what we know from astronomy. Find out whether we can determine what celestial body or bodies were the Christmas Star.

When he gives this talk in person, he uses an application called Stellarium to demonstrate the night sky, and some scripts that he wrote that show the rotation and location of the celestial bodies at the time of Jesus’ birth in the city of Bethlehem. You can find links to download his presentation, Stellarium (which is open source and free for all desktop operating systems) and his scripts on his blog: bartbusschots.ie/s/2015/12/01/christmas-star-astro2-december-2015/

Chit Chat – After the Logo

New (to Me) Digital Audio Workstation – Amadeus Pro

amadeus_logoNow that the logo is done I had no excuse for not getting the show going. I mentioned earlier that I also thought this week would just be that much more challenging if I also changed recording software. Apple has been on a tear lately either abandoning software altogether (like Aperture) or coming out with a new version that loses much of what we know and loved. One you may not have tracked is GarageBand. A while back (more than a year) Apple rewrote GarageBand and it’s worthless for podcasters. I’ve hung onto the old 6.0.5 version all this time but I live in fear that they will one day come out with an OS update that renders it unusable. After 10 years of podcasting with GarageBand as my Digital Audio Workstation, I switched over to Amadeus Pro from hairersoft.com.
