NOTE: I would now recommend not to use Quicktime Broadcaster because of a nasty bug. For an alternative, see: </hugo/2005/04/advanced_podcas.html>

QuickTime Broadcaster Just keeps on going!

I did a trial using QuickTime Broadcaster as a recorder. Here are the results.

Update: The setup is the same as described before with ‘Line-in’ replacing GarageBand and QuickTime broadcaster replacing the SoundTrack application.

Stresstest

Test 1

QuicTime Broadcaster set to MP4 AAC recording 16 bits 44.1 kHz stereo at 64 kbits/second (~ 6.8 K bytes /second).

-> Line-in microphone captured with the ‘line-in’ application.

-> Quicktime Player playing 4 tracks simultaneously.

-> iTunes playing songs continuously.

-> DVD Player playing a DVD!

-> iChat session with continuous music coming from the other end.

<- iChat session (same as above) continuously streaming the final mix to the other end.

<- Output to Headphones.

- Recording straight to disc.

This test was run using my normal user account with several apps running in the background.

Result: Several dropouts when the DVD was playing together with the other tracks.

Test 2

QuicTime Broadcaster set to ‘Apple Lossless’ recording 16 bits 44.1 kHz stereo at 82.5 K bytes /second.

-> Line-in microphone captured with the ‘line-in’ application.

-> Quicktime Player playing 4 tracks simultaneously.

-> iTunes playing songs continuously.

-> DVD Player playing a DVD!

-> iChat session with continuous music coming from the other end.

<- iChat session (same as above) continuously streaming the final mix to the other end.

<- Output to Headphones.

- Recording straight to disc.

This test was run using my normal user account with several apps running in the background.

Result: Brilliant!

Almost no dropouts! (Only 2 tiny ones, barely audible, that I caught.)

Is this the perfect setup?

Thanks for the guidelines! I was just messing around and had quite good luck with LineIn and WireTap 1.0 - both free. I’ll have to try some more with QTB.

Hugo:

Can you give more details on this set up with detailed settings to make this work? Pics help too … can’t get this to work. I can either record with voice and music and not hear in headphones or I can hear it all and can’t record anything.
