I'm having the same problem. I’m currently running version 6.03 of SoundTap.
I carefully listen to the original source music while the recording is being made and there is no pop. When I play back the file it's there. SoundTap is set to save the audio file as a WAV file.
I tried re-recording the same music from the same source and the pop noise happens again, but at a different time within a song.
1. What were you recording at the time?
Music from Amazon Music. I've tried other sources (Spotify) and got the same problem.
2. If you know the technical details that would be great. ie. bitrate, mp3/aac
Unknown. The Amazon quality setting is set to HIGH.
3. Were you doing other work on your computer at the same time? It should be fine to do so, but it could help me track down the problem.
No. No other work was being done. Just listening to the music being recorded. No system sounds either - all turned off.
4. What kind of soundcard are you using?
Onboard sound card. HP Envy desktop Z9M79AV with Realtek High Definition Audio. Driver version 6.0.1.8237
5. Have you changed any settings on your soundcard. eg. Have you changed the default playback format in the Speakers/Headphones Properties dialog? If so, what are the settings?
Everything set to default settings. Format 24-bit, 48000 Hz. All enhancements turned off.
6. Does this problem occur every time you record?
Yes
7. Does the problem exist after a reboot?
Yes
8. Can you save a small snippet of the recording you made so that I can analyze it and track down the issue? If so, I'll contact you via email.
Yes. I opened a support ticket and attempted to upload a sample file via FTP. I'm not sure the sample uploaded correctly. I used a couple of different FTP applications and I received a server error - unable to display directory.
