This week, a ton of e-mail to answer from the last month or so,
including some reminiscing about the transition from analogue to digital within the radio industry through the late ’80’s and early ’90’s,
Ron Eastwood tried recording quasi-binaural on a boom box,
Jim Addie sent in a link to an interesting article on the merits, or lack thereof, of recording at higher sample rates and longer wordlengths (when I recorded this episode, I commented that I hadn’t read the entire article. I now have, and have the feeling that at some point in the past, I’ve been pointed to it, and have actually read it. Still, it was good to read it again!),
Greg Andreson (who is all “Bruced” out) wrote to tell me about his Zooms (the H2 and the H4!) and how much he likes them, and to comment on the wildly different standards of audio production that exist within the podcaster community,
and Pascal asked about sidechain compression.
One free VST plugin that I know of which does sidechain compression is Sidekick.
And finally, a bit of a chat about what is in store for episode 100.

This week, so many e-mails to answer, I couldn’t get to them all!
Jim Addie chimed in with some follow up on DC offset (thanks, Jim!),
Steve Mayfield wondered if I’d got my HDMI issues sorted (Yes! Thanks, Steve).
He offered a link to another site that reviewed some hand held field recorders, registered his ‘vote of confidence’ for a video podcast for SL100, and expressed his appreciation of the new audio2u.com podcast imaging.
Then, we heard from Ike Tamigian who owns the Tascam 122L audio interface and reckons that “for the money you can’t go wrong”. Thanks Ike!
Then, Noel Payne asked about what eq filters (high pass, low pass, notch, band pass etc) to use under what circumstances. And after I finished editing the podcast, I realised there’s more I need to add to this topic, next week. Stay tuned, Noel!
And finally, Ron Eastwood wrote in with a photography analogy regarding sample rate and bit resolution, and asked what is the most important factor (with regards audio quality)?

Hold on to your hats, people…
In episode 92, a listener (who wishes to remain anonymous) commented on the possibility of hearing damage inflicted by driving with the windows down, and the possibility of same being caused from riding your pushbike in busy traffic. The earplugs he’s using while riding are these.
Of course, my regular listeners know that I love my Sennheiser CX300’s… damn, I oughtta be on commission!
And that led to a discussion of noise-isolating vs noise-cancelling earbuds and headphones.
All of which led me to speculate on telephone handsets and whether or not they do us more harm than good.
Then, Jim Wesihorn checked in with news of a new pdf from the good folks at Izotope (makers of the VST/DirectX Ozone mastering plugin).
Seems they’ve turned out a whopping great 75 page document on audio restoration.
Going to have to check that out some time soon!
Then, Steve Mayfield sent me a link about a dummy head binaural mic for your video camera!
Crazy looking thing.
One would hope it works well given the price tag!
Another long time listener who wishes to remain anonymous wrote to assure me that no, there is no distorion in my podcasts!
Phew! What a relief!
I didn’t think there was, mind you.
He also went on to provide some interesting real-world feedback on sample rate conversion.
Then, Matt sent me this screen shot of the Pro Tools manual where apparently, even Digidesign doesn’t know the difference between “bit rate” and “bit resolution”.
Why do I feel like I’m fighting an up hill battle here?
Then, Luke asked about vocal training.
I suggested googling some of these words:
‘voice’, ‘vocal’, ‘coach’, ‘training’, ‘tuition’, ‘diction’, ‘eloqution’, plus your local area
or check your local phone book.
Next, E. Bernhard Warg sent me an mp3 of a shoot out between a Coles 4104 ribbon lip mic and a standard lav mic, with regard to ambient noise suppression.
Then, Jim Addie sent in some great information on how the Red Book standard was established.
And finally, there were some listener comments on audio2u about my disaster last week.
June 15, 2008
In episode 91, Felix left a comment on audio2u.com regarding “ratios”,
Kevin Smith asked about selecting sample rates in your multitrack project,
which led to discussions on the Nyquist theorem,
and the DVD-A spec,
Ross Bennett wrote to say that a) he loves my new mic, b) appreciated my discussion on near field and mid field monitoring in ep 90, and c) to remind us all that good monitoring is all well and good, but we should also take some time out during a large mixing session to listen to a mix we respect so that we don’t get lost in our work.
Plus, Leon McCormick wrote to ask about the processing of my voice when I’m reading out the e-mail.

This week, some e-mail to answer regarding what sampling frequency should we use as a default and why,
utilities to use for ripping and encoding your mp3’s,
how to mix podcasts that prevent your listeners from falling asleep (an area in which I apparently succeed!),
and recording audio on a laptop.
Also, Bruce’s recent home theatre trials and tribulations.
Speek’s multi front end
January 6, 2008
I wasn’t planning on doing another podcast this early in the year, but a couple of e-mails came in, and I figured I may as well just get on answer ’em!
This week, an “end of year” greeting from long-time listener, Gary Lerude. Thanks mate!
John Meadows asked about what effects or processes get over used, and which don’t get the attention they deserve. (NB. The one thing I should have also mentioned which doesn’t receive the attention it should is mic technique!)
And Vassya asked about why 44.1 kHz or 48kHz, dither, and headphones.

This week’s episode was inspired by a comment on the Zoom Handy H2 portable recorder blog post.
Joseph (from English Mojo) asked about what to look for, and what to avoid, in a field recorder.
After running through a checklist, I moved on to a discussion of how to calculate data storage requirements based on given sampling rates, bit resolutions and channels.
Here are some of my notes:
1hr @ 44k 16 bit stereo = 10MB/min or 605MB/hr
1hr @ 44k 32 bit stereo = 20MB/min or 1210MB/hr
1hr @ 48k 16 bit stereo = 10.9MB/min or 659MB/hr
1hr @ 48k 32 bit stereo = 21.9MB/min or 1318MB/hr
1hr @ 44k 16 bit mono = 5MB/min or 302MB/hr
1hr @ 32k 16 bit mono = 3.6MB/min or 219MB/hr
1hr @ 22k 16 bit mono = 2.5MB/min or 151MB/hr
MP3 (CBR 320)
1hr @ 44k 16 bit stereo = 2.29MB/min or 137.3MB/hr

In episode 2, Bruce describes how to set up both Windows and Audition, so you can record your voice from a microphone into Audition.
