The problem:
My wife is in the Broadcast Journalism program at BCIT and often has to make telephone interviews for her assignments. Technically speaking, this has always been a really sloppy process. She has to hold the phone up to the recording device, which introduces lots of ‘noise’ to the recording and often her voice is louder than the interviewee. This causes her to have to import the audio into GarageBand and edit the audio levels.

The Solution :) :
The other day it dawned on me. The iPhone has a line out!

Required Hard and Soft ware:
1) iPhone or any Phone with a line out
2) In our case we use a MacBook or MacBook Pro but any computer with a line in will do.
3) QuickTime Pro or any software with audio recording capabilities will do.

I plugged a line from the iPhone’s headphone jack into the line in on her MacBook (pictures show my MacBook Pro):

Switched the input to ‘Line In’ in ‘System Preferences’ -> ‘Sound’:

Start up QuickTime Pro and selected ‘File’ -> ‘New Audio Recording’:

A QuickTime Audio Recording window will come up. Increase the volume to about half. This will allow you to hear the interviewee over the speakers of the computer ( you can also plug in headphone if you don’t want it broadcast ) and press big red button whenever you want to start recording:

Once you stop you will find a Audio.mov file on your desktop:

Let me know if you have any questions or another method…

    Very cool idea!

    Here’s some questions/ideas:

    How do you speak back to the person?
    Do you use the speaker phone?
    Does your own voice get recorded as well if you use the speaker phone?
    Would it be possible to wire to a microphone as well? (the included headphones have a mic built in so it must be possible as well?)

    Cheers!

    How do you speak back to the person?
    >> You would use the phone like you normally would.
    Do you use the speaker phone?
    >> No, it is line out..
    Does your own voice get recorded as well if you use the speaker phone?
    >> No, just the person on the phone.
    Would it be possible to wire to a microphone as well? (the included headphones have a mic built in so it must be possible as well?)
    >> I’m sure, as the iphone headphones are just that. ;)

    Hi,

    Thanks for that great idea!

    I was wondering, if you plug a line from the iPhone’s headphone jack into the line in on a Mac, how does it record my voice (what I say)? I mean… will not only record what the other person says??? Maybe this is a rookie question. haha

    Thanks a lot,

    Etienne

    I’ve been trying to figure out how to record a conversation, but this doesn’t work at all.

    You CAN’T have a conversation because not only does it not record YOUR voice talking to the person you are recording, but the person you are recording won’t be able to hear you at all.

    It’s not just a line out, it’s a line-in as well. That’s why the jack has 3 bands on it. Left, Right, and Mic.

    If you take an audio cable from the iPhone and put it to the line-in on the Computer, it will record the person talking. But there’s no way for your voice to go through the phone. Put it on speaker doesn’t work because it shuts off the audio to the line-out/in port on the phone. The only thing you’ll get on your audio recording is the person going “hello? hello? HELLO?! ”

    I looked for a third party app on the iTunes app store but found a bunch of regular memo/voice recorders that didn’t talk about phone conversations.

    Let me know if you come up with something.

    Great idea and thanks for doing this. I recently wanted to record some calls. Like your wife, I have to conduct a lot of phone interviews. This is a great solution and not cost-prohibitive. What kind of line out cable do you use? Are there are other recording software programs thatare free and can also be exported to Twitter audio feeds?
