I’m trying to record audio played back on a website. Capturing it with other tools is very complicated and I’d just like to record it while it’s playing. I need it as a .wav file anyway.
I’ve selected the WASAPI device and selected my speakers as source. I’ve tried it with either the analogue speakers as well as the S/PDIF digital output (each configured as default playback device in Windows for the process). The project sample frequency is 44.1 kHz and 16 bit. When I hit the record button, nothing happens at first. As soon as I start the playback on the website, the recording starts. The recording itself is good, but right at the beginning, at around 2.0 sec, a short part is missing. The recording skips about half a second of the played back audio. The rest of the recording has no skips. This is 100% reproducible, it happens every time I try at exactly the same position.
Windows 10.1709 x64
Audio drivers from Windows Update
The last time I recorded something from a website, I didn’t notice this problem. Also, the recording started immediately when I pressed the record button, not just when I started the playback. That was with Audacity 2.1.3 on Windows 10.1607 x64, like a week ago. I recently reinstalled my OS.
Update: I’ve found out that this issue does not occur when I set my project sample rate to 48 kHz before recording. Since I need 44.1 kHz output, I have to convert the sample rate once before saving to file.
