Audacity Works!
Friday, November 24th, 2006My dad was pondeirng purchasing some fancy software to record his LPs to CD. I told him not to waste his money. With a couple extra steps (and $0 spent), Audacity may do what he wants. So I showed him the semi-complicated mess on how to connect his laptop to his turntable.
- Turntable connects to the Receiver’s Phono jacks.
- The lapop’s Line-In connects to the Receiver’s Tape Out (or Record Out)
- The laptop’s Line-Out connects to the Receiver’s Tape In.
- Select the proper recording source on the laptop.
- Adjust record levels on the laptop so that the peak volume in doesn’t exceed max threshold.
This works, and works extremely well. You can record and playback without having to swap anything (except pressing Tape on the receiver when wanting to hear the laptop, and pressing Phono on the Receiver when wanting to record/hear the LP).
I record the first side of an LP and play around with it in Audacity. I have found the easiest way to filter out most of the “snap, crackle, and pop” associated with LPs.
- Make sure you have a good portion of silence where the LP is playing but there isn’t any music. You need a sample of the “snap, crackle, and pop”.
- Apply the Click Removal filter to the entire recording. You may play with this filter’s adjustments if you wish, but I just left them at their defaults.
- Find a section of silence that has the most “crap” in it. You only need a few seconds. Highlight this section, open the Noise Removal filter, and click ‘Get Noise Profile’.
- Highlight the entire recording, open the Noise Removal filter, and click ‘Remove Noise’
The recording won’t be perfect, but it’ll be a heck of a lot better than it was! If you are a perfectionist, you can tweak with the recording some more. However, my dad and I have been satisfied with the results by just doing the above. (It’s his project, so I’ll let him do watever
).
