Tips for recording from Skype and other voice chat (VoIP) apps



One of Audio Hijack’s most popular uses is to capture audio from voice chat (or VoIP) applications, particularly Skype. We’ve made this easy to do with the Voice Chat Session template.

Voice Chat Recording Basics

To get started, choose "New Session" in Audio Hijack to access the Template Chooser, then select the "Voice Chat" template. This template provides a default setup which works quite well for recording voice chats. Using this setup, both halves of a conversation are pulled in and recorded, but you'll only hear the remote party in your headphones.

You'll notice that this template sends audio to both a Recorder Block and an Output Device Block, in parallel. This audio sent to the output device is adjusted with the Channels effect. It duplicates the remote audio (on the right channel) into both ears, so that you only hear the remote party. This won't affect your recording, only the audio you hear as you chat.

Advanced Voice Chat Settings

When a voice chat app is set as your source, Audio Hijack will automatically configure it to:

1) Pull in audio from both the remote party, and from the microphone you're using with Skype. This is controlled by the "Include audio input" setting in the Advanced options for the Application Block.

2) Split audio into two channels, placing the local audio (you) on the left, and the remote audio (the other party or parties) on the right. This is controlled by the "Split between channels" setting, also in the Advanced options for the Application Block.

While this setup is generally what's desired, you can always adjust it by change the Advanced settings, as pictured above.

Using Headphones When Recording Voice Chat

It's essential to use headphones when recording voice chat with Audio Hijack.

It's always best for all parties to use headphones with voice chat applications. This prevents any sort of echo or feedback loop in the audio. You've likely seen radio DJs with closed-ear headphones on. They're wearing them to prevent the audio they're hearing from leaking in to their microphone, and the same idea applies to your voice chats. You want to isolate the other party out of your microphone.

Some voice chat applications, such as Skype, do some rudimentary noise cancelling. This is an attempt to make it possible to not use headphones while chatting. However, it tends to not be 100% reliable, and it definitely won't work when recording with Audio Hijack.

So again, be sure to use headphones when recording voice chat with Audio Hijack.
