About ten years ago I digitized quite a lot of casett recordings by using Audacity. Now, however, things do not work the way they did. There are of course new versions of Audaticity, and I’ve got a new computer (Windows 10).
This is my problem: Even though I’ve plugged the line signals from the cassette deck into my computer in the traditional way, there is no sound recorded in Audacity. (I’ve chosen Microphone Array-Realtek as input source.) (Line out from a Sony TC D-5M.) It seems as if some weak signals entering Audacity come from the internal microphone. The same things happen when I plug an external microphone into my computer. But the sound from my microphone in the Headset (Platronics) is recorded perfectly.
Right… That’s a combination mono-microphone input and headphone output. A regular headphone plug works for headphones but it takes a 4-contact [u]TRRS plug[/u] to make the microphone connection so if you ever want to plug-in a microphone you’ll need the right plug or an adapter.
