Mixed results…
Good: found a pretty stable setup that keeps recording even if the system’s under stress.
Bad: with enough stress on the system it is still possible to get ‘jumps’ in latency to the headphones. This is (luckily) practically not audible in the recorded result though.
What follows in this post is a summary of the setup. A diagram and the actual test recording will be posted later.
The setup
- Microphone input through ’line in’.
- Hijack line in to Soundflower (2ch).
- Add your Microphone effects such as compressor and reverb to this Microphone/ line-in Hijack channel.
- With Soundflowerbed, set buffer of Soundflower (2ch) to 64.
- With Soundflowerbed, route the output of Soundflower (2ch) to built-in audio.
- Connect your headphones to built-in audio.
- Set the default system audio output to Soundflower (2ch)
- With Soundflowerbed, set buffer of Soundflower (16ch) to 2048.
- Hijack Soundflower (2ch) to Soundflower (16ch).
- Record Soundflower (16ch), recording AIFF format uncompressed.

I have done a really weird setup using a motu 828 instead of using a headset or built in mac audio input. The setup works suprisingly well and latency is irrelevant because I can record three separate files to the same drive. I have each speaker (myself / interviewee) and the mix of both of us going to separate aif files. Keep in mind that this is going to a Medéa RT SCSI Raid on an adaptec 39160 card so it’s definitely fast enough for this. I was frantic about whether or not I could do both streams to separate files , it works great. Another thing is that I’m using vonage softphone as skype has too much echo not for me, but for the person I’m calling. This is unacceptable when interviewing high-profile personalities and Vonage seems to work just fine. I even have iChat and Yahoo IM running in the background, mail, and a few other apps as well. (during testing only) …All of this works really well considering it’s such a “hack”.Thanks to boards like this , I’ve solved a problem in 48hrs and can make my interview tomorrow without a hitch!
