    i was a recording engineer during the time analog recording was just starting to get surpassed by digital

    I’ve got a cassette of some parody songs made by a local radio station that’s basically going to become lost media if I don’t digitize it myself. The only cassette players I currently own are a Walkman and one of those retro-style-but-not-old CD/cassette/record combo players. Do you have any advice on what I should do to get the best quality transfer that I can?

        1st thing i would do would be call the radio station–they might have a digital copy already

        It hasn’t existed since 2003 (there’s still a station on that frequency, but it’s changed ownership and programming a couple of times). Maybe they still have the old master copies anyway? Or I suppose I could try to track down the DJs who produced it…

        The library and state archives ideas are good suggestions; I’ll look into them.

        last resort would be a recording studio, which might cost lots of money per hour, and it’ll have to be converted in real time–play the tape from start to finish, while the computer ‘records’ it. if the studio don’t have a top of the line gourmet tape deck, then they can take just take the output of your own player and plug it into protools

        I mean, if using my own player might be considered “good enough,” couldn’t I just hook my Walkman’s headphone output to the line in or mic input on my computer and do it myself? In addition to the audio built into the motherboard, I also have a relatively-cheap USB audio interface, which I guess isn’t as good as it could be (it’s 48KHz, not 192KHz) but would still be better than nothing.

        The main thing is I’m not sure how I need to set the volume on the Walkman (it also apparently has a feature called “AVLS” that might or might not be relevant) or if I need an amplifier or something. I also don’t know if I need to do anything special with ALSA/JACK/PulseAudio and know basically nothing about how to use Ardour or XMMS (I’m aware they exist and are the right type of software, but that’s about it).

      While the quality won’t be particularly good, a cheap cassette-to-MP3 converter off Amazon can ensure that the material at least isn’t lost forever. Run the tape through 2-3 times to make sure you get at least one decent copy of everything. Once you’ve got that done, escalate as suggested by solsangraal to get a better transfer.

      That’s actually very easy to do and you don’t need any special equipment. Simply use a male-male 3.5mm cable and connect one end from the stereo output of the cassette player and the other end into the microphone jack of any computer you own. Play the cassette - you can test the audio quality by running arecord -f cd - | aplay - - you will have to tune the volume output of the cassette player and the input sensitivity of the microphone.

      From there, if you’re paranoid, you could use arecord to save the output to a .wav file and encode it once the recording is done, but I had no problem just using oggenc directly on the piped audio. The final command looked like this: arecord -f cd - | oggenc -q 5 -o file.ogg - (change to -q 10 if you want lossless encoding).

      I’m not sure if this is the best quality per se, but I would definitely recommend it over using specialized equipment like cassette-mp3 converters. The problem with those devices is that if they use underpowered hardware, you might experience buffering issues where the encoding hardware can’t keep up with the audio stream or something like that. But doing it on a computer ensures that you will have all the processing power you need to make sure that this doesn’t happen.

      Good luck! I found it very easy to do - it took 5-10 minutes of setup.
