Portable Recording Devices

Thursday, August 28th, 2008

Ran across some interesting news yesterday. Alesis is touting a soon-to-be-released product called the ProTrack, which makes an iPod into a portable field recorder. Supports 5G and Classic iPods and 2G/3G Nanos. Sounds exciting, key is $$$ ?
Here’s a good thread on Macintouch on the subject as well.
Alesis also has the IMM8USB 8 channel mixer with integrated iPod Dock, using the iPod as the final destination for the mixer.

Here’s another, taking a very unique approach to the matter – integrating it into a hand held mic. Way too rich for my blood though.
The HHB DRM85.

And I’ve enjoyed the Belkin TuneTalk Stereo as well.

I concur with IHR’s analysis that the flash-based Nano’s provide much better results in regards to disk fragmentation (as it causes ’skipping’) with hard disk based iPods. I experienced the same with my 5G Video iPod. Also, for sound effects recording, or recording ambiance, you can hear the hard drive spin-up, so the Nano rules. And the processor feels faster on the (3G) Nano, more quickly going in and out of the dialogs for the voice recording screens.
Here are some recordings of thunder and ambiance using the TuneTalk Stereo on a 3G Nano. One, two, three, four.

Speaker Building Tool For OS X

Thursday, July 3rd, 2008

I’ve never been so excited about Windows. The de-facto standard free speaker building (mainly woofer/subwoofer cabinet calculator) application, WinISD is only available for Windows. There is a free online version, but now with an Intel based Mac you can run WinISD on a MacTel for free using Darwine. This screen shot is a bit “Beauty and the Beast” as far as GUI’s, but it works!

Techno-Babble[on]?

Thursday, June 5th, 2008

Mike Sessler mentioned this podcast in a recent post of his, here’s the iTunes podcast URL for this episode from Mars Hill Church entitled “Spirituality of the Cellphone”, it’s a must. Below are my initial comments on Mike’s blog’

Tower of Babel

“Right on Mike. In a lot of ways I find technology further defining and making ever-so-blatant the distance (or on the better days the nearness) there is to other people. We have so many more options for communicating, and yet we don’t make use of them. It can make more plain to us those we are near to, and those we actually aren’t, even though we wouldn’t admit that. It makes the distance grow greater in a sense. I have asked myself this a time or two; does my gospel and my lifestyle work when “unplugged.” With digital photography now you could [almost] take 100 photos in your sleep, but when participating in family or church events I feel challenged to balance the “one for posterity” and the here-and-now when it’s much easier to just be the face behind the lens. Modern day scribes is what we could be called, recording sermons and capturing photos and video, it can give God material to work with in the future to show us where He’s taken us and where we’ve come from. Some of us maybe need to take it more seriously – the fact that we’re capturing the “yesterday’s” of tomorrow, some of us maybe need to not take it so seriously.”

Church Podcast Guide

Church Podcast Guide – Create a Sermon Podcast for your church
I’ll add one omission I see in this article and that is that your podcast does not need to be stereo, mono is fine, it’s speech… there’s nothing to pan. Every software (and iPod/MP3 player) knows to put the mono signal in both speakers, no worries. And it cuts the file size right in half – free lunch! Don’t be duped into doing stereo just so your intro music (if you use any) is in stereo… the message is the important part and mono will get it done perfectly fine. Another omission from the getting good signal section is dynamics compression, simply put; you need it like you need air if you’re going to do a podcast (of any kind involving speech) that will be tolerable to listen to in a variety of listening conditions/environments. If I remember I’ll append a photo of my (hardware) compressor setup to this post. See this article of mine on software [dynamics] compression.
As promised, see below photos of my compression settings on a Behringer Autocom Pro for our main speech mic (LX series Shure w/SM87 head), and a wide shot showing the 15 band graphic EQ channel that follows it in the signal chain (a Rane ME-15.)

Griffin iMic 2 USB Audio Interface

Wednesday, April 23rd, 2008

I was finding my MDD G4 to be so noisy when monitoring during audio editing. I changed some things in my setup that brought it to a head and I sought out an inexpensive audio interface option just to get away from all the digital hash being created by my jam-packed MDD.


Griffin iMic2

I went with the Griffin iMic 2 figuring it should at least get me away from all the interference happening inside the G4, and it surely did. I have no methodical measurements to offer but suffice to say if you’re finding the stock outputs of your MDD (or any computer) to just be too blasted noisy, give the iMic 2 a try. I don’t know if it’s all the stuff crammed in the thing or what but even the headphone output on the front panel is annoyingly noisy.

Digital Photography & Workflow Thoughts – Part 4

Wednesday, April 9th, 2008

I was reminded on one of my own rules to live by when it comes to principles of use of a digital camera when I put my Olympus C730UZ into the hands of my 9 year old, so while it was fresh in my mind I figured I’d relay some observations and opinions about some points to ponder.

DSLR

1. Spend plenty on large denominations of storage media whether CF, SD, MS or xD. Read on for the reasons. A corollary to that is buy plenty of rechargeable batteries. If your camera uses a proprietary battery buy at least a second one and keep it charged/rotated.

2. Always shoot in the highest quality/resolution JPEG possible (native resolution, not interpolated as some cameras have, that’s a farce), or RAW if you have a DSLR and will be using an advanced workflow that handles RAW well (Aperture, Lightroom, Photoshop, or asset management.)
Because… You never know how timeless, unique or otherwise valuable the images that you (or your family) capture may be. You can always throw them away after the shoot if you determine otherwise, which is a parallel to point #3. If the only purpose for your images will be 4X6 prints, maybe you can ignore that point… Maybe.

3. SHOOT! When in doubt, shoot! The only real soft expense involved in shooting more than less is the potential time it may take to wade through the images after the shoot. The main hardware expense involved in this philosophy is a one-time investment in larger media than you maybe would buy if you were far more conservative (…and hard drive space.) For just around the house use, not factoring in trips or remote events, you can probably do fine on 256MB. But the second you walk out that door, the thing you have to realize is, you can’t go to the corner gas station and buy a roll of “film” (but you can go to WalMart and buy more media :) , so you have to plan ahead and make sure you’ll have enough media to capture the event or trip. Which leads to point #4.

CF Media

4. Keep your media cleared off. Don’t leave images on your card for months or even weeks. This does 2 things; helps you properly file or tag your images when you import them because the event is only a few days or a week old and you’re less likely to look at an image and have no clue what it is. The other thing it does is help you get the most mileage possible out of the media you do own because you will most likely have all the space available when you go to that event.

5. Backup your images on CD and some other form of live media i.e. a secondary and/or dedicated hard drive (besides wherever you have your primary library stored) or website or something, CDs are not reliable as the sole backup of your life images – do not trust them. They may make a fair off-site backup, which is another strategy to seriously consider – storing at least CDs of your library at a family members house. With the cost of media, it’s very affordable to (and inexcusable to not:) have off-site backups, which means unless your entire town is struck by a natural disaster, you should have something to fall back on if a major catastrophe befalls your dwelling.

6. Keep the time and date set correctly on your camera. Metadata is only good if it’s accurate. When is as important to me as what and where. If you are using rechargeable AA’s this is a real factor to stay on top of. If I don’t use my C730UZ within 7-10 days, those NiMH batts are prone to running dead on me and then my clock is reset and I’ve added another 50 images with the date of 01/01/00 and time of 12:00 am.

Audio Batch Processing With Amadeus Pro

Thursday, March 20th, 2008

I was on the warpath today for batch processing options, as I have been many times before. Amadeus Pro ($40) is not an app that I remember getting a hit on before when doing these searches, but I hit it today. I already had Amadeus Pro in my toolbelt, thanks to Geoff Hankerson, so I thought I’d check out these features (honestly since I have Peak I just didn’t do much exploring to start with.) As I mentioned in this post, I have a workflow I follow to generate the two different quality Mp3 files for my churches sermon downloads. I’ve been looking for a way to cut Peak out of the picture, just for the sake of doing it. Today I think I hit on another option, all things being equal. I discovered the batch processing options in Amadeus Pro. Here are some screen shots of the setup I used, the -a arg in the LAME window forces mono (even though my source files are mono I had to do this to get Amadeus to recognize and output as such, there is no option in the main encoder section for number of channels.) This also means that the bitrate selection appears to be of the output file, after channel conversion, whereas in my example with iTunes, all bitrates are stated as stereo, you just do the math to pick the one for the desired mono bitrate. Translation; I wanted 24k mono, so rather than setting it to 48k (and divide by 2) like I would in iTunes, I set it to 24k.

Adding an AudioUnits plugin to the action list, my parametric EQ setup as a high pass.

There are a ton of things you can do in batch mode. After I researched the command line args for LAME I added the -a for mono conversion so I didn’t have to do it as a stereo to mono conversion though you can do that as an action item too. I also experimented with normalizing, there are a couple options there including RMS normalize and fixed percentage (or dB) normalize. You can retain the input file format, however if you want to change the bitrate of a source MP3 file, you have to specify MP3 as the output format and set your encoder options there as shown. There are more expensive options ($70) as well for the hardcore production user, unfortunately the demo does not allow batch processing so I couldn’t “let the machines speak” for themselves. Comparing it to my Peak & iTunes workflow it took 1:22 to process my test file – open in Peak, apply Parametric EQ (as low cut), export as AIFF, re-encode with iTunes. Using Amadeus Pro it took 2:38 for the same source file and the same operations. This is on the same MDD 2 X 1.25GHz G4, 10.4.11, 1.75GB RAM machine. Based on sheer speed, Amadeus was not a runaway winner. But for a large group of files and a persons sanity (or schedule), Amadeus Pro is a viable option. Granted this is an extremely narrow test (I didn’t set out to do a review, just to find a better mousetrap), other functions may be faster, and if there were more gyrations to be done that had to be done serially in Peak I wonder if Amadeus wouldn’t show a gain there as well. Tests were done on the latest version 1.2.1. Bottom line; if you’re on a budget and need to do production-like processes with audio files, Amadeus Pro has a lot to offer, especially for the money.
