- Why? I want to explain to others who want to know how to remove artifact also...

- Upload the XMA file used in the video you posted before so I can do a comparison.

- I don't understand. You want the original XMA or the XMA converted for the video ?

- Mygoshi, we're glad you were able to figure out a way to fix the files, but we suspect that something odd is going on that you aren't explaining correctly. We want the original XMA so we can do the conversion ourselves.
We're trying to understand what is going on, as converting to WMA instead of PCM WAV shouldn't result in any quality improvement. ffmpeg is almost certainly doing an internal XMA->PCM->WMA conversion. It might be that something else is playing back WMA and WAV differently on your system (or on Youtube?). Or maybe you're playing the old ToWav WAVs instead of the new ffmpeg WAVs?
It would be most helpful if you also include the exact command line you used with ffmpeg, both with converting to WMA and to WAV.
Thanks for putting up with us trying to understand this.

- Ok, so the XMA i'm giving is not from the same game, but it's exactly same artifact problem with guitar instrument or saxophone for example. This one is not XMA 32khz through, (like the video), but this XMA i'm giving is a 44.1kHz.
Here's the XMA : https://mega.nz/#!j5VzETII!2GY1Rg-_wHfxU-ZJWQc7bdqOzuMVioVC4QAJ1h_-DVQ
And here's the command I used to convert into wma : ffmpeg -i airport_race_4.xma -ar 48000 -b:a 320k airport_race_4.wma
and to test to wav or other I simply did : ffmpeg -i airport_race_4.xma airport_race_4.wav (that ToWav do automatically) or ffmpeg -i airport_race_4.xma -b:a 320k airport_race_4.wav (not sure if I have to put 320k or 4096)
You will hear that WMA remove the artifact (not totally) on guitar instrument, and WAV or MP3 don't remove it. (but I think WAV is better if you don't think about artifact, just quality)

- Why are you changing the sample rate from 44100Hz to 48000Hz?
- by Mygoshi at 1:57 PM EDT on May 31, 2016
- Isn't better?
- by hcs at 2:37 PM EDT on May 31, 2016
- It's better to have audio sampled at 48000 than 44100, but you can't make 44100 better by resampling to 48000; resampling can't recreate frequencies that are missing from the input signal.

- Did you test my solution for artifact ?
