I would like to record in stereo on my MacBook Pro (Catalina 10.15.7), but I don’t know what sound card to use. I have a cable that converts two channels (RCA plugs) to a 3.5mm plug. I also have an older Logitec sound card that takes headphones (output) and a mic input that accepts my 3.5mm plug and converts to USB.
Audicity 3.0.4 recognizes the sound card, but when I choose it as the input source, it forces 2 (Stereo) recording to 1 (Mono) Recording and will not let me choose stereo. The card is working, since I can record mono, and stereo recording works with the Built-in microphone.
I hope that there is a reasonably priced external audio card that will work with this configuration, but when the listing (Amazon, eBay, whatever) says Stereo, it often means stereo output (like I already have with my Logitec card). Are there cards out there that will allow me to record in stereo? Any other techniques I need to know?
Thanks,
Tom
