Several listeners of the www.chvrchespodcast.com have said they have audio playback issues with some of the podcasts.  After several weeks of testing, I was able to get the weird sound issue to happen on my Apple iPod Touch.

So I created several example files to post to see if others can reproduce consistently. These are recorded originals from my Marantz (one in MP3 format and one in WAV):

• Download Marantz MP3 44.1 (Original).MP3 (235.9K) [Original]
• Download Marantz WAV PCM 44.1 (Original).WAV (2594.6K) [not expected to play on an iDevice because it is WAV format]
• Download Marantz WAV PCM 44.1 (Exported as WAV 16-bit PCM).wav (1243.4K)  [not expected to play on an iDevice because it is WAV format]

The following were imported into Audacity 2.1.2 on Windows and exported out:

• Download Marantz WAV PCM 44.1 (Exported as MP2 160kbps then to MP3).mp3 (113.5K) [Export #1]
• Download Marantz WAV PCM 44.1 (Exported as WAV 16-bit PCM then to MP3).mp3 (113.9K) [Export #2]
• Download Marantz WAV PCM 44.1 (Exported MP3 Constant-128kbps-JointStereo).mp3 (113.9K) [Export #3]

If any of these MP3s don't sound right [Original or Export #1, #2, #3] on your computer or iDevice, then can you please let me know at: [email protected].  Thanks!

Update #1 (9/30/2016 11:15 AM PT) - My friend Victor was not able to find any sound quality playback issues on his iPhone 7 or iPad Pro.  Neither could play the WAV file but that is expected.  The WAV file sounded fine on his Mac.

Update #2 (9/30/2016 11:15 AM PT) - These MP3s all sound AOK to me on my iPad Air 2 in the Chrome browser.

Update #3 (10/2/2016 1:45 PM PT) - The first original MP3 and Export #2 and Export #3 make no sound on my iPod Touch running iOS 10 using Safari browser. Export #1 sounds like high-pitched clicks and beeps.

Update #4 (10/14/2016 - 9:11 AM PT) - These seem to play find on multiple Android devices, Windows PCs, Macs, Chromebooks, and Linux Desktop OS via multiple browsers.  I verified the podcasts play via iTunes also on various platforms other than iPhone 6 devices.

Update #5 (10/14/2016 - 11:43 AM PT) - These are two new test files after swapping all the cables I am using in my recording study.  RAW MP3 directory from Marantz and then an output of the Marantz MP3 from Audacity:

• #A.) Download Swapped-Cables-Marantz-MP3-Original.MP3 (280.0K)
• #B.) Download Swapped-Cables-Audacity-MP3-Output.mp3 (112.7K)

This is not meant to be a definitive list, but just a list of possible software solutions for podcasters to consider when they want to record a Microsoft Skype call.  These have been mention to me in the past by a podcaster who at the time said they worked for them.

For Windows:

• MP3 Skype Recorder
• PowerGramo
• SoundTap

For Macintosh:

• Audio Hijack Pro

For Linux:

• TBD

Personally I've only used Audio Hijack Pro and then I do all my editing in Audacity (Mac, Windows, Linux).

There is a new version of Audacity v1.3.7 (beta) and I've loaded it up on my Mac Book Pro. I used it to mix down the Jersey Boys Podcast #66 without any issues.  I've been using the previous version - v1.3.6 (beta) - without any major problems, and I consider this release to be production quality.

Some of what I think are the most important fixes and updates include:

• Fixed periodic exported stereo files issues
• Fixes for Nyquist effects, Compressor and Noise Removal
• Fixed WAV corrupted issue related toi overwriting the same file
• MP3 and WMA now export correctly with all supported metadata
• Platform-specific bugs for: Vista, Windows, Mac, Linux
• Improved F11 Full Screen mode
• Improved Windows DirectSound API support
• Improved latency correction using fixed correction value

Another Audacity related item of potential interest, is that the audio for my presentation at the New Media Expo 2007 has been posted to the Podcast Academy site.  Here is a link to the PDF slides and a screencast QuickTime movie of the slides.

You might have a pretty good online training experience listening to the audio from the Podcast Academy site and watching the QuickTime Movie at the same time.

It is rough times for most everyone with the world-wide economic downturn and uncertainly.

In the podcasting world, Podango has announced potential shutdown plans.  For the digital picture world, the wonderful magazine & online site JPG has also announced plans to shutdown. Even "big media newspapers" are reportedly on their way to Washington DC for potential handouts.

In situations like this, I think turning back to fundamentals is key.  Here are my three suggestions:

1. Do what you do best and do that better.  If you offer three services, pick one, and focus all your energy on that one service making it the absolute best.
   
2. Focus on key partnerships that are mutually beneficial. Going it alone is miserable.  Branch out and find a partner that makes your one focus area shine for both you and them.
3. Plan for investments.  If you haven't, then you need to start.  Even with cost cutting, you need to make sure you are devoting a good percentage of your available resources into future research & development (R&D) to "catapult" you forward when the market turns positive.

I'm pretty sure there are other great suggestions out there.  If you have one or many, then please let me know what they are by commenting below.

NOTE: I would be remiss if I didn't point out a great discussion thread by Michael Geoghegan on the "Podango" annoucment on his MWBlog.

I will be presenting at the New Media Expo 2008 (August 14-16, 2008) a "Getting Started With Audio Editing" session using Audacity from 2:00-3:00 p.m. in room N245 on August 14, 2008.

I have created a set of WAV files that will make up my examples and demos that folks who are attending might want to download if they plan to try to follow along during the presentation.  The link is here (34-MBs .zip file).

I also have posted a copy of my Audacity 101 DAU eLearning 2008 workshop slides in PDF format, and a link to a Blip.TV movie that includes the screencasts that are embedded in the presentation. Unfortunately the movie is not sync'd with audio so you have to work your way through them without narration.

NOTE: I will be doing my demos at PME 2008 using the Audacity v1.3.5 (beta) release.

There was a question the other day on the New Media Expo Pathable Community mailing list about how to record phone conversations via POTS connections. 

I use a Telos-One-R (R = rack mountable) that I picked up on eBay and this is a diagram of my setup:

The Telos One comes highly recommended from two very smart audio gurus at IT Conversations: Doug Kaye and Paul Figgiani. 

Paul has posted some great resources about the topic over at Podcast Rigs especially this post "Telos One, Talkshoe and Skype." There is also a great podcast with Doug Kaye (MP3) over at Podcast Academy that covers this topic.

Both Paul and Victor Cajiao at the Typical Mac User Podcast helped me setup the configuration of my unit - which is done manually with a small screw driver. I also borrowed Paul's unit diagram of a Telos One for my picture.  Thanks Paul!

I am pretty happy with how this is working now, but I would recommend doing some post production processing on the phone track (usually your guest) with something like SoundSoap.

Online registration is now available for the 4th annual New Media Expo 2008 in Las Vegas, NV from Thursday, August 14 through Saturday, August 16, 2008.

I will be presenting an updated version of my "Getting Started With Audio Editing - Hands-on With Audacity" interactive session at this conference.  This presentation is in the "Track 1: Audio and Video Creation 101" series, and will be held Thursday, August 14, 2008 from 2:00 pm - 3:00 pm.

If you are new to podcasting, audio editing, or to the open source multi-platform Audacity audio editing and production tool, then this will be a great session for you to attend.  This year's expo looks to be as good or better than previous years. 

If you can't wait for New Media Expo 2008, here are some references that I've done on the topic of audio editing with Audacity:

• PNME 2007 - Audacity Presentation In QuickTime Format
• PNME 2007 - Getting Started With Audacity Slides
• Podcast Academy 3 - Audacity 101 Slides (June 2006)
• Blog Post "What Gear Do You Need To Podcast" (January 2005)

The audio for my PNME 2007 presentation is available via Podcast Academy.

NOTE: There is an audio version of my Podcast Academy 3 presentation in the archives of Podcast Academy, but those are being transferred from GigaVox Media at this time and are offline.  As soon as link becomes available, I'll post it.

PodcastFreeAmerica.com reports that eMarketer is has published a new report that the United States (US) podcast listening audience has reach 185 million in 2007, and that advertisers are increasing the use of podcasts to reach audiences.

I am not sure how this really fits into individual podcast producers other than it looks promising that their shows could be potential advertising avenues if that is something they are interested in. 

It is also good news for the medium in that is appears that more and more people are tuning in with their attention and time to new media vs. traditional media options.

A new version v1.3.4 (beta) of Audacity has been released for Windows and Linux.  The latest version for the Macintosh is still v1.3.3 (beta).

This new version has a host of new features and user interface improvements.  According to a press release here are the major ones:

• New Welcome Screen with introduction to Audacity.
• New 'Mix and Render to New Track' command.
• Support for VAMP audio analysis plug-ins.
• More keyboard shortcuts and navigation.
• Reworked solo/mute handling.
• New preference: Select all audio in project, if none selected (on by default).
• New preference: Beep on completion of longer activities.
• Envelopes: Many fixes when copying, pasting, or repeating.
• Many translation updates.
• Metadata editor added for OGG, FLAC and WAV/AIFF exports.
• Metadata import improved.
• Muted tracks are no longer audible in the exported mix.
• Improvements to latency correction.

I have installed this on two Vista PC systems without any major issues, but I do most of audio production editing on a Mac Book Pro so I have not completely run this new version through the paces.

The recent This Week In Tech (TWIT) #126 podcast with Leo Laporte had an interesting snide comment at around 18 minutes in by Podshow's John C. Dvorak about Revision3's long list of new talent (including the recent Rodger Chang), and how quickly the are now going to run through their venture capital (VC) money. 

The same could be said about Podshow's spending rate, business plans, or financial status which little is known publicly.  One good thing is that they appear to still be hiring.  And they continue to have the annoying pre-roll advertisements on many podcasts on their network.

Given the apparent implosion at PodTech.net there is a lot of uncertainty in the technology new media arena as we close out 2007.

It will be interesting to watch how TWIT, Podshow, and Revision3 play out their relationships in 2008.
