EXACTLY the same thing with me too. For example you open a file. Press R to record / overdub, if that option is selected. It’ll record, but then insert a slight gap. Is this what you’re talking about? I’ve tried to research how to remedy this problem but to no avail, but it did inspire me to reply to this topic. Task Manager doesn’t do a single thing to improve. As a practical matter, because I’m blind, it’s critical for me to have Jaws in the background, so closing all programs is an impossible step for me. The sample rates match. I have no idea on the specs of my Laptop, though my Dad can tell me. All I know, being blind, it’s a Toshiba, with Windows 7 64 bit. Please note this does not happen when I record a single track. Single tracks record like a charm. It’s only when I overdub, is when that little “crack” in the playing (at a random time) starts to happen. Host is Windows Wasapi, playback is "Speakers (Realtech High Definition Audio), and recording device is my absolute favorite, “Speakers (Realtech High Definition Audio) (Loopback)” because it records the audio exactly how it should, i.e. no white noise, Jaws is in the dead center, just perfect! Since Youtube conversion is illegal I loopback the videos instead, no I never share them, of course. Well anyway, you and I are probably in the same boat. Changing the Afinity does nothing to alter this problem either. Drivers are all up to date. I have deselected “Update display while playing”, disabled all the View options, set preview length to 0, tried to deselect the features that apply only to the dang mouse (blind, remember) - still no difference. However, after the crack, due to my latency correction being set at 42.08, they are in total sync. It’s just why is it cracking like that? I must make clear that it ONLY, ONLY, ONLY happens when overdubbing. Single-track recording (44100, 32 bit float, stereo) is no problem at all. In fact, Audacity and Jaws are the only programs I’m running. Any you guys explored other options and found this cracking to go away? Thanks
Why are you overdubbing when you are recording computer playback? There may be a better way to do whatever you are trying to do. If you are overdubbing you should normally use a microphone recording device to sing or play an instrument.
WASAPI host is prone to a dropout (which may sound like a click) in the first second or two of recording. It is noted in the Release Notes: http://wiki.audacityteam.org/wiki/Release_Notes_2.1.2#wasapi. If you need to use WASAPI host then try setting the Audacity Project Rate to 44100 Hz and setting Default Format in Windows Sound to 44100 Hz, with both “Exclusive Mode” boxes unchecked. Restart Audacity after making changes in Windows Sound.
Recording YouTube videos (if you don’t have copyright holders’ permission) is just as illegal as downloading them. I recommend downloading the videos, without converting the audio. Check out how using your favourite search engine. You can then install FFmpeg and drag the videos into Audacity. At that point, the audio is still in as good a condition as it is in the video.
I tried unchecking the Exclusive boxes in the control panel and there is no difference. Only reason why I’m overdubbing recording with Wasapi is just to have fun and to experiment. Both sample rates match, so that probably won’t work either.
When you said “Drag” the videos into Audacity - remember, I’m blind, I don’t use a (swearword) mouse. In fact, I don’t even know how to actually download a video. I can view it, but I’ve never found a way to download them. Also for clarification, no dropouts occur when I record a single track with Audacity. To me it sounds like you probably think that I have a dropout with a single-track recording - this isn’t the case.
OK. Audacity’s WASAPI support is still fairly experimental in that it has not been improved much since first implemented.
Sorry about using the word “drag”, but you can use the normal import method you use for audio.
Your favourite search engine will show you how to download videos. it is often done by using an extension for your web browser. We can’t post methods here, naturally.
I understand that you have the dropout or click when overdubbing, but the dropout I have in mind does tend to happen when using loopback, or when overdubbing (which isn’t usually loopback). There is no obvious workaround I know of with WASAPI, if 44100 Hz set both in Audacity project rate and Windows Sound does not help.
Robert J.H. here is also blind and I know he uses WASAPI quite a lot. No doubt he will reply if he has anything to add.
If you have stereo mix enabled in Windows Sound then you could use that with MME or Windows DirectSound host in Audacity, but the best workaround for sound quality might still be to download the videos.
Yes, I’ve noticed that Stereo Mics isn’t the greatest. There’s some static that just can’t be gotten rid of, which is why I use Loopback in the firstplace. Stereo Mics is like second place for capturing the computer playback, Loopback is first place. That reminds me. There’s a blind-oriented program from American Printing House for the Blind called “Studio Recorder”. Its editing functions, for me, are easier than in Audacity because you can scrub anywhere in a file and you can align where you mix a file with what’s on the clipboard, without having to open mouse-only toolbars and rely on someone sighted (with no roommate in college, that’s impossible really). I only have the demo, so my workaround is, do whatever in Studio Recorder, keep the file open, open Audacity and record using Loopback while the project in Studio Recorder plays. Now who says I’m cheating that way? Haha… What if it’s a super long file and you only want to record some of it, but you’re not sure how to select using Audacity - it works great for that too. If you buy it for $200 the only option that becomes available is to save files, that’s it. So why pay for it when you can just work around it with Audacity and the free version of SR? I know, I like free stuff, but hey, that’s most of us. That’s why we have Spotify, isn’t it? Finally, you might want to check it out. www.aph.org/Tech - click on “Studio Recorder, electronic recording software”. This might actually provide some inspiration for making Audacity more blind-accessible, who knows.
