In your image, why does only the middle track of the three called "Aoeo part 1" have a spike? Were those other imports from another copy of the file?

Which is the other audio application? It's OK to give the name, as we are asking.
Sawyer Anderson wrote:you can't hear the spike on the mp4 before i import it into audacity so it's not something that is there by default.
Please upload the MP4 to DropBox or your favourite cloud server and give us the URL to download the file. Please tell us the exact times in the file where you can hear or see a pop.

Also please clarify if this is correct or not:

1. There are three tracks from top to bottom in order. 1. Mixed 2. Mic and 3. Desktop. Not sure why the Mic audio has spikes when the Mixed Audio is both the mic and desktop.

2. The other audio app was Mixpad

3. I'll upload the mp4 but as ive said before you can't hear it in the recording from the times on the audacity timeline

4. Yes that is correct. OBS records my video/audio the audio is the three separate tracks as mentioned above.

Could you upload the sample somewhere that does not require logging in, thanks. There's some suggested methods here: viewtopic.php?f=49&t=72887

Sure i can do that heres the .wav

Also another thing that just came to my attention on this fine Monday afternoon. My Setup during these issues was (-.- ( Desktop / Mic /Desktop )) anyway i sat down this afternoon after coming home from work and the computer was off (Therefore no sound whatsoever) any way i'm siting here doing nothing when i hear this clicking sound that after investigation appeared to be coming from the top left corner of my right desktop screen. I am not 100% sure if this is the issue i am experiencing but i will move my setup to .-- to get the mic away from both screens. (However i do live in Alaska so it is entirely possible my screen is poping due to expanding a contracting in the cold/warm temps we get on a normal day in the current season it can get as low as 25 on a night and a high as 78 during the day. The room my PC sits in is temperature controlled however only by an AC/heating unit as we lack central heating up here to keep the house a cousey all around temperature. ) I'll do a test with my new setup to see if the poping presist in my audio and if not i will assume it was the clicking from the screen.

Thanks. I doubt that the popping in the recording are due to thermal effects as these pops are clear patterns of numeric data.

It could still be due to an effect of invalid data, but by the time it has been converted to WAV it has become "real" data. What I need to do now is to look at one of your mp4 files that does not pop until imported into Audacity.

Right now, everything is pointing at occasional bad data in the mp4 file. If Audacity is the only program that has problems with the MP4, then it could be a bug in Audacity.
What other players have you tried playing the MP4 with? I'm betting that it's not just an Audacity issue.
It may be possible to workaround the problem by converting the MP4 to WAV with another program and then import the WAV into Audacity, but my guess is that any FFmpeg based converter will have the same problem.
