I have been using Audacity for a good while to record many LPs to mp3. Love it. Works great.
I have a music DVD and I’d like to have its song list added to my mp3 library with everything else. No problem. I can set input recording device to “Microsoft Sound Mapper - Input” and away I go.
Problem is… I get a real time reverb effect as the audio is being recorded. I have Software Playthrough on so I can hear what I record. While the DVD plays via Media Center, it sounds natural; when I listen to Audacity as it’s recording, it doesn’t - it has a reverb effect. I can start / stop recording and output naturally switches between Audacity and Media Center. The difference is quite noticeable; it’s not an effect I want in my recorded mp3 files.
How can I get clean, natural recordings from a DVD? This has never occurred when recording from vinyl. I’ve tried to negate (reverse) the reverb effect after the fact, but no luck.
You need to mess with the sound control panels. That reverb is Audacity recording the performance twice, once directly from the DVD playback, and then once again from the Mix Out, or WAV Out, or something like that. There is a small processing delay between those two and that’s what you’re hearing.
It’s also possible you will not be able to hear what’s being recorded in real time, that the monitoring service is being recorded along with the show.
There are two different signal pathways involved and your job is to figure out each path and stop one of them.
Koz, thanks for the info, however I don’t see anything in the Audacity recording configuration that might impact this issue.
Maybe I just don’t see it, but can you (anyone?) be more specific?
I can’t believe I am the first Audacity user to encounter this. Seems like it would be more pervasive than just my individual hardware/software setup/config.
You’re quite correct - these kind of issues are some of the most common on the forum.
The settings that you are looking for are not in Audacity, but in your operating systems sound mixer application.
Unfortunately, the exact details vary depending on both the operating system, and the sound card drivers - some soundcards (notably “Realtek”) use their own mixer application instead of the default OS application, so the pictures in the tutorial may differ from your set-up.
