How Can I Convert Tapes to CD?
Before you donate that cassette player to the local charitable organization or send it to an electronics recycler, you might want to convert your library of tapes to CD for posterity. It won’t be fast but it can certainly be worth your time. All you need to convert tapes to CD is a cheap cable and some simple, free recording software.
The plan is to get the tunes from the cassette on to the computer’s hard disk. From there the files can be burned to CD. The tunes will be sent to the computer using the cassette deck’s line-out or audio-out ports, or the headphone jack. If using audio-out ports, you’ll likely need a cable with red and white RCA jacks on one end, and the other end will have to match the line-in port you’ll be using on your computer’s soundcard. Typically this is a 1/8-inch (3.5 mm) mini-stereo jack. This type of cable is available at Radio Shack® or any electronics store.
If you’ll be going from the headphone jack to the soundcard, you’ll either need a standard ¼-inch (6.35 mm) stereo jack on one end, and a mini-stereo jack on the other; or if the deck is built into a portable boom box it might also have a mini-headphone jack. Adapters are also available to convert a cable you might already have.
When converting your tapes to CD, be sure the cable is long enough to set up the cassette deck where it will be stable and out of the way, as it might spend some time in this location. Though it might be okay to set it right next to the computer, it’s probably better to set it a few feet (meter or so) away to avoid potential interference expressed as signal noise.
Many free recording programs are available to convert tapes to CD by capturing incoming audio signals that you can then save in the audio format of your choice. One very popular, free and open-source recording program is Audacity™, available for Windows®, Macintosh® and Linux® users. Wave (.wav) files are great for burning to CD, however if you want to save room, you can save to a compressed format like .mp3 as long as you’re willing to sacrifice some quality.
With cable in hand, turn on the cassette player and adjust the volume so that it’s audible without being loud, then attach the cable to the cassette deck and sound card. Let the tape continue to play while you setup the software (you’ll restart the tape in a minute). Be sure the “line-in” option is enabled in the software and you might have to access your sound card settings to enable line-in on the card too.
Once line-in is enabled on both the sound card and software, you should see the signal registering in the software on meters that represent the left and right channels. You should also hear the signal coming out of the computer speakers. Adjust the software gain (or cassette deck volume if necessary) until the signal looks good for recording. If the meters are registering the volume too low, the recording will be too soft, but if the meters are registering the signal by peaking into the red zone, the recording will be distorted.
Once adjusted, click record and let the software capture about 30-45 seconds of whatever portion of the tape is playing. Click stop, and pause the tape in the cassette. Play back the recorded section listening to the sample with headphones. If you make adjustments to the volume or gain, record another snippet to test the new settings.
Rewind the tape and start recording from the beginning. If using Audacity you can edit the recording when finished, deleting long entry silences or applying E.Q. filters to improve the overall sound.
The entire cassette can be recorded as one large file, saved and burned with any CD or DVD burning software to disc. Another option when converting tapes to CD is to record each track from the cassette separately, pausing the tape between tracks to save the current song as its own file before recording the next song. This is more trouble but rips each song making future options more flexible for using the tune in different compilations or on portable players. You can also record the cassette as one large file then use editing tools to chop the file into separate songs. Wear headphones for this process to avoid clipping fade-outs.
The wave format consumes about 10 Megabytes of space for every minute of audio, while MP3 consumes up to ten times less. Depending on how much free space you have, you might need to convert some tapes to CD, delete the files, then record more. Whatever strategy you use, you’ll no doubt find it was more than worth the effort to commit your tapes to CD and listen to those old favorites once again.
