"What do you recommend as a good laptop headset with microphone for making Skype calls and voice recording?"

If you have a laptop with Bluetooth built in, you can frequently use the same Bluetooth headset you would use for your cellphone for placing Skype calls. This can get confusing if you get a phone call on your cell phone while you're in the middle of a Skype call on your laptop, so having a separate headset with built-in microphone often makes things a bit easier. I have a few recommendations for headsets I like.

"I want to do some voice recording and I know I need a mixer and a compressor, but I'm wondering if you know which mixer built-in compressor combo might be best?"

Which mixing board with built-in compressor is best for your needs depends on a number of factors. You need to determine what your budget is. Do you need only one mixer channel with compression or multiple channels? Do you want portability or is this a mixing console you plan to install permanently? Those are all questions you need to think through before making a purchase. Here are some mixers with compression built-in at various price ranges:

"I have recorded some tracks in Audacity using the project sample rate of 44100Hz. I also imported a track from a portable device at 16000Hz. All tracks sound fine when played simultaneously. However, when I want to insert an audio into the 16000Hz file, it is
distored. I have 2 questions:

1. Is there a way to integrate the two files into 1 track; and
2. Will I have a problem exporting mixed sample rates to CD?"

Mixing sample rates in an audio project can cause all sorts of problems with your final output. There is an easy fix to your problem, which is to simply resample one of the audio files so that it matches the other files.

Portable Recording Booth As someone who travels regularly, I'm always looking for creative ways to get better sound from my audio recordings. Hotel rooms tend to echo and you don't always have control over the environmental noises. I went looking for a solution that would offer a more controlled sound and ran across professional voice actor, Harlan Hogan's, Porta-Booth, which is built from some fairly common components. You don't have to travel to find this solution useful, it's also a great way to tighten up your sound when recording at home without needing a whole room dedicated to recording. Making a few slight modifications, I put together a video showing how I built my own.

Required Components for the Portable Voice Booth

Cutting Foam with a Knife

Studio Foam The biggest variation between my portable sound studio and the one Harlan Hogan demonstrates on his site is the foam. He uses Auralex Studiofoam 2" Pyramid foam, which is only available via special order from places like Guitar Center in $400 increments (or $200 via Amazon) - I know, I checked. I opted for a sheet of 2x24x48 Auralex Wedge foam, which runs about $25 per sheet. It got the desired result and I don't end up with a box of leftover foam. The sheet is big enough to make 2, which is also the minimum number of cubes you can buy, so get a friend in on this project and save money. Any local music supply store should have similar foam.

Whitmor Cube The Witmor 14x14 collapsible cube ships in quantities of 2 for about $12.99 at Target.com, Wal-mart.com and Amazon (by way of Target). You can't get them in stores for some reason, so you'll have to order online.

Bread Knife You need a bread knife for cutting the foam - trust me it works better than anything else. A cheap Chefmate knife or any of the $4 or under variety, like the World Kitchen/Ekco 7" Bread Knife from Amazon are great solutions for this. Don't use your wife's bread knife unless you plan on buying her a new one.

Additional Tools The only additional tools you will need is a tape measure to make sure you cut the foam in the right place and a Sharpie to mark the foam to make the cut.

Assuming you already have a Sharpie and tape measure, you're looking at total cost of approximately $42 plus any tax and shipping for materials to make 2 of these cubes.

Space Saving Bags For Storage

I bought the Large Space Bags 3 pack from Target for my packing solution. You can get both the Space Bags and the Whitmor cubes through Amazon's affiliation with Target and spend less on shipping for the overall package (you can likely get a bread knife this way as well).

"Is there an RSS feed with my YouTube videos people can subscribe to?"

YouTube recently publicized a bunch of RSS feeds for subscribing to popular topics and categories, but they haven't made it obvious how someone might subscribe to your YouTube channel via RSS. Thanks to their well documented section for developers, this is a relatively easy. Each YouTube user has their own unique RSS feed in the format:

http://gdata.youtube.com/feeds/api/users/jakeludington/uploads

Just replace my YouTube username, with your own YouTube username in the URL and you'll have an RSS feed of only videos you uploaded to YouTube. You can find more ways to access your YouTube information, like an RSS feed of your Favorites and Playlists, see the detailed YouTube API documentation.

A slightly different approach to this, including an enclosure with a SWF video file, is to use a URL like this where the file is in the format username.rss. This is a little more complicated because other people could tag their videos with your user name and show up in your RSS feed.Here's an example:

Amazon didn't officially include podcasting support when they shipped the first Kindle devices, but that doesn't mean you can't listen to your favorite podcasts on the Kindle (or your favorite songs for that matter). There are actually two interesting ways to make this work:

1) You can play any MP3 audio file as background music on the Kindle. You transfer MP3 files to the Kindle using the USB connection, to either store audio on the device or on an SD card. Then from the Home screen do the following:

Scroll to the Menu and select Experimental

Select Play Music on the screen shown

This will continue to play until you click the Stop Music option in Experimental (or the Alt+P keyboard shortcut). You can jump to the next track using Alt+F.

2) The more useful way to listen to podcasts on your Kindle is by adding them to the Audible folder either on your device or on your SD card. This is actually designed specifically for listening to Audible Audiobooks, but also happens to work with MP3s. Once you have the MP3 files in the Audible folder, the Kindle treats them just like other audiobook files allowing you to jump back 30 seconds, skip ahead 30 seconds, play and pause audio.

While you can't subscribe to podcasts directly on the Kindle yet, these are two ways to use it as a podcast listening device.

Download mp3DirectCut

MP3 files recorded directly with a voice recorder often require some editing. Many MP3s downloaded from the Internet need editing to trim unwanted sections. Both of these scenarios result in better quality audio when the MP3 is not re-compressed after editing. Enter mp3DirectCut, which provides an interface for directly editing MP3 files without first converting to a PCM audio format. mp3DirectCut speeds up the MP3 editing process in a number of areas, providing direct access to cut, copy, and remove sections of an MP3 in a non-destructive editor without ever needing to recompress. This saves time, disk space and eliminates the generational hit of decompressing and recompressing your MP3 files during editing. Note: If you install mp3DirectCut on Windows Vista you will need to run the installer as administrator. [Windows 9x/2k/XP/Vista $0.00]

Recording environmental sounds like singing birds, wild animal calls, water running through a streambed, or the chirp of baby birds is one of the more fascinating (and challenging) aspects of audio recording. Some of the same audio recording techniques apply when recording things like car noises, lawn mower engines and other man made sounds, but you don't always get a chance to do a second take with nature like you do with machines.

Getting started in recording nature sounds requires three basic things:

1) A recording device, like a MiniDisc recorder, Compact Flash recorder, or other digital audio recorder.
2) A stereo microphone or stereo microphone pair
3) Headphones for listening to what you're recording

The big reason to use a digital recorder is to avoid the hiss that comes with using a tape recording medium. The stereo microphone or pair of microphones provide the listener with something much closer to what you'd hear in the real world than a single microphone accomplishes on its own. A microphone zeppelin windscreen is also useful for cutting noise from wind while recording.

You also need a good dose of luck and patience in order to find the specific species of bird or animal you're hoping to record. For a great overview of what's required for recording sounds from the wilderness, the Wildebeat Podcast has a great interview on recording the sounds nature with Kurt Fristurp (of the National Parks Service Natural Sounds Program) and Dan Dugan (of the Nature Sounds Society). Two great tips from the podcast are how to find places free from unnatural sounds and some of the basic techniques for getting a good sample of the sound you hope to record.

One of the best places to get a quick foundation in how to record nature sounds is the Nature Sounds Society. Their Question Bird service provides a solid foundation of answers for people looking for detailed information on the types of audio gear you need for recording various kinds of natural sounds.

You won't get great sounding recordings by recording telephone calls with an iPod, but it is possible. In an ideal telephone recording scenario, you want independent control over each person on the call, so that if the person you call is too quiet, you can turn their volume up or your volume down. You won't get independent volume control for both sides of the call when recording a telephone conversation on your iPod, but you will get a recording that you can later use as part of a podcast or transcribed interview.

To record phone calls on your iPod, you need two things in addition to the iPod. You need a microphone add-on for the iPod and you need an adapter to pass the phone audio to the microphone.

Download Wavosaur

Wavosaur is a lightweight audio editing application with VST support. All the basics are covered here, including support for multitrack audio files, trimming, adding effects, making loops, and normalization. Most processing settings are also available for batch conversions, making Wavosaur a handy tool for applying the same settings to a bunch of files. I like are the option to remove silence in a batch, which is a convenient way to speed up spoken word audio without altering pitch. A vocal removal preset also scrubs music files of vocals, so you can make your own karaoke tracks in a batch. The vocal removal doesn't always get chorus sections perfectly scrubbed, but it shouldn't hurt your ability to sing over the top of the file. The application runs as a completely standalone executable, meaning you could put it on a thumb drive and use Wavosaur anywhere. The user interface is generally more intuitive than the popular freeware app Audacity, but the two make nice companions rather than being replacements for each other. While Wavosaur doesn't bundle all the features of things like Sound Forge and Audition, it does most of the common audio tasks well at a price neither of those two apps can touch.
