I'm posting the following because several people have asked about my recording equipment:
- Microphone: Shure SM57
- Recording Software: GarageBand
- Computer: MacBook Pro Laptop
- Digital/Analog Converter: M-Audio FireWire Solo
The microphone plugs into the left channel of D/A converter and I plug my iPhone into the right channel (the iPhone plays the play-a-long track). The D/A converter's output then plugs into the firewire port of my laptop. GarageBand does the actual recording which I then export into an mp3 to share on this website.
There are plenty of other applications you can use to record, many of which are cheap or free. Audacity, for example, is free, runs on a variety of operating systems, and is open source.
Note: the above represents my setup since 2008. Prior to that I used a Windows computer to record, with CubaseSL as the recording software.
