When I play “google Translate” speaking, everything plays fine. As soon as I start recording through Audacity using Windows WASAPI, google translate speaking voice really slooooooows down.
I have tried both Firefox and Edge, same effect.
This seems to be effected only through Google translate, I just recorded YouTube and it recorded just fine.
System used:
Audacity 2.4.1 (I had same issue in previous versions)
Device recording from: Speakers (Realtek High Definition Audio)
OS: Windows 10 PRO 64 Bit
System: HP Z620 Workstation
CPU: 20 core 2X Xeon E5-2680v2 64GB
I may have a piece of this. If your sound file or clip plays slowly, that usually means it was recorded fast, or the digital sample rate was higher than the system was expecting. Recording computer sound playback sends the work through several unusual steps and an error in any of them can cause problems.
If the voice presents at 22050, for example and you’re trying to record it at a more standard 44100, the voice may play back at half speed.
I’m not just making that up. If you change the sample rate of an Audacity track with the drop-down to the left of the track, you can speed up or slow down the show. If you change it with the “official” sample rate window at the bottom-left of the Audacity window, the show sample rate will go up and down without affecting voice pitch.
So if you really just want to correct the recording, that may be one way to do it.
That sample is a shift from 44100 to 22050. That may also tell you what the original sample rate was, because it’s the only one that will sound natural. We also need to pay attention to voice quality when you do this shifting trick because the fidelity or crispness of the voice changes with sampling rate. It will never be any better quality than the lowest rate.
