I am a long time Audacity User. I use it primarily to edit music for performances. I usually use music from Spotify and occasionally from YouTube.
Several months ago, my recording quality deteriorated substantially. I assume it coincided with some update, but I don’t know if it was Audacity or Windows 11. But, I can no longer use Audacity for that reason.
My previous setup had used Windows WASAPI as the host. I had used it for years. Now, when I use it, I get an error message: “Error Opening sound device.”. If I change the host, it will record but the quality is muffled; totally unusable.
I am a total loss of what to do about it. I have worked through all of the help files I can find and nothing.
Note that you may have to start playback before you start recording (but I don’t think you should get an error message). WASAPI can record a silent stream but it can’t record “nothing”.
Some computers/soundcards have “What-U-Here” or “Stereo Mix” which work similarly to capture/record what’s coming out of your soundcard.
The bottom of This Page has some alternative suggestions. Total Recorder has a reputation for being foolproof but it’s not free.
