Hi,

I’m having a problem with a glitchy audio playback (checked on Win, Mac & Linux). To reproduce:

  1. Import the sine_60Hz_48kHz.wav test file from the zip I’ve shared to your new project’s content.
  2. Press ‘Play’ to preview in the editor:

3.You should hear a glitchy version instead of a smooth sine wave (please listen to the captured version from the zip folder).

This is also visible in the below spectrogram in audacity:

Hello mgudk,

I have a couple of questions to help narrow down the issue you are having.

  1. Does the issue occur if the audio sample rate is 44100 Hz or 22050 Hz?
  2. Does this happen with other sounds that you are using?

Thanks!

Hi ,

  1. I’ve changed the sample rate of my test file to 22050Hz and 44100Hz and the issue still occurs. I’ve also changed the Sample Rate in the Project Settings to the above values (to test different combinations) but the problems persists.

  2. Yes, I’ve tried some other files and the problem occurs to them too.

Cheers!
