Tutorial: Recording a Two-Way

I love Skype, and I hate Skype.  OK, hate is a strong word, but when Skype doesn’t work, when I find myself battling Skype, I feel like a goalie fighting the puck.  I’m trying to wrestle with it, and make it do what I think it should, rather than what it wants to do.

Skype is a great tool, don’t get me wrong.  It replaces hundreds of dollars of equipment with free software and a free service, and if you have someone on the other end of a Skype call who knows what they are doing, the results can be quite spectacular.  But the service can be frustrating as well, from changes in audio quality mid-call, to the ducking that is inherent when one person talks over another.  There are some solid tutorials on how to set up Skype for podcasting (like this excellent one from The Conversations Network), but in the end, if you record just the Skype call, one person will wind up sounding better and different than the other.

But my friends, there is a better way.  And you can do it with Skype, or just with a phone if you needed to.  It’s called the two-way.

A two-way recording is one where you record each end of the conversation locally, and then combine the two recordings later.  The final output can often sound like you are in the same room as the other person, and will give you the best possible quality for your recording.  Many radio interviews are done this way, with a host in one studio, and the guest in another.  If you have ever listened to NPR, and they tell you that a guest is in a studio at a member station, this is what they are doing.

You already know how to record a Skype conversation so that you can split the audio of yourself and the caller into two separate audio files.  For a two-way, both sides of the conversation will be recording the Skype call, in the same way.  I recommend both parties record the Skype call, and not just their own audio.  This way, if something were to go wrong with either person’s recording, you have the Skype call as a backup.  Also, recording the Skype call will help with any timing drifts.  Even though computers are good at recording audio very accurately, they tend to lose timing in tiny increments.  You won’t notice this much in a single, local recording, but you may notice it when you combine the two recordings.  Recording the Skype call seems to anchor this timing a little better.

OK, so you’re recorded your call, and your podcasting partner has recorded theirs.  The next step is to transfer the audio from one computer to another.  When I first started recording two-ways, I set up an FTP account for the other person to upload the audio to my webspace, which I would then download.  This was fine after some initial hiccups, but since then, I have started using Dropbox to transfer my files around.  Sharing a Dropbox folder allows me to transfer files with various people, and it’s drag and drop simple.  I use Dropbox folders to send voice-over recordings to people as well.

Once you have the other party’s audio, you can combine the two audio files in your editor, each side of the recording getting it’s own separate track (and therefore, it’s own processing and mixing).  Make sure that you have made the files mono, and mix them together in your digital audio software like you would any other audio.

As a quick tip, when you start your recording and before you start your show, have you and your partner count down from five.  When you go to combine your audio, line up this countdown, and you will be very close to the correct timing.  You may have to tweak the timing a bit (moving a track forward or back a half second or less) to really make it sound tight, but you will be very close.

The fun thing about recording a two-way is that you can do this with as many people as you like, at the same time.  You could record three, four, or more people, and combine them all later.  Doing this may seam labor-intensive, rather than just putting out a Skype call, but when you have multiple recordings, all with just one voice on a track, it can make editing out a section of audio a lot easier.  You don’t have to fight the cacophony of voices to find a good edit point, you just edit it like any other two-side conversation.

If you don’t have Skype, or don’t have access to a solid internet connection, and you still want to record a show, you can use a cell phone, and record each end of the conversation.  I did this when I was in Alaska and the internet was problematic, and other times when Skype was having issues beyond my control.  Recording a two-way can free you from the shackles of the single point of technology we rely on all the time, giving us more recording options (recording from the field, for example).

One final thought on the two-way: It isn’t for guests.  You have seen the setup involved in recording a Skype call, and for a two-way, you have to have this ability on both sides of the connection.  Walking someone through the setup may be simple for a regular podcaster, or someone used to recording audio, but for a one-time guest, they may not be up to the task.

I record the Avs Hockey Podcast as a two-way most of the time, since I am away from Denver quite often and don’t get the opportunity to be face to face with my show partner. Jay and I have found that this is the best way to make our podcast sound as good as possible.  You can hear an example of a two-way we recorded here.  You would have to listen pretty hard to be able to tell that we aren’t in the same room.

I hope this helps, and if you have any questions, please ask.  Comments are open.

Recording Skype with Audio Hijack Pro

I tend to travel a lot.  It’s a major part of my job, so I don’t get to have a regular podcast studio setup.  So I record almost all of my podcsats over Skype.  I love Skype for what it is (and I will talk about what it is – and isn’t – at a later time), and without it, I would have a much harder time recording my shows.

For my initial recordings, I use a program called Audio Hijack Pro.  I can’t say enough about AHP, and they people who make it have some really useful programs.  Audio Hijack Pro allows you to record the audio output of any program or source on your computer.  From the Rogue Amoeba site:

Record any audio – three simple words to explain Audio Hijack Pro. Record from applications like iTunes, Skype or DVD Player. Record from microphones, Radiosharks and other hardware. If you hear it, you can record it.

They aren’t kidding.  Audio Hijack Pro can record straight off your browser, into many different formats.  And at $32 US, it’s dirt cheap for such a helpful program.  But for our purposes here, we are recording a Skype call.

First, you want to set up AHP to record your Skype call on two separate channels of your audio file.  This will give you your audio on one side of the stereo file you wind up with, and the caller audio on the other.  Skype mixes all incoming calls together, so there is no way to break out separate incoming calls into individual tracks.

You can see on the image below that I have the Skype recording area open, and the input tab selected at the top of the window.  Click on the ‘Advanced….’ button, and you will be presented with a dialogue box:

Audio Hijack Pro Settings

Go ahead and set it up as shown, with the output on the left channel, and the input on the right channel.  If you would prefer to have your audio on the left channel and the caller audio on the right, just swap which channel the input and the output is on.

Now you can record your session. Clicking record will launch Skype (even though AHP can hijack the audio if Skype is already running, it is best to launch AHP first, and let AHP open Skype). Recording will start when the Skype call starts, and stop when the call ends.  If you want to start recording a new file, you can stop recording and start again, or push Split, and AHP will start a new recording in a new file.

I tend to watch the meters in the Effects tab of AHP, just to see what the volume looks like.  You can always edit the files later to adjust each individual track.

Skype Being Recorded

After the recording, you will be able to find your new file in the Recording Bin. I have a lot of files in there right now, and should really clean them out.

Audio Hijack Pro Bin

There are several other tools for recording Skype calls out there, but this is the one I use (partly because it does so much more as well).  If you use something else, can you leave a comment below?  I will try to do a round up of tools available soon.

Next tutorial, I will show you how to split this new file into two separate tracks, so you can edit it individually.  Hope this helps!
