QuinLoft Posted December 20, 2022 Report Share Posted December 20, 2022 Hi all, Trying to troubleshoot some weird audio popping. One thing I've noticed, is for some reason whenever I have an audio file coming up, Watchout seems to pre-load it 3 seconds beforehand, not 0.3. I know this because the speaker pops like something is turning on 3 seconds before the clip is due to start. I know the first thing will people will suggest is to put a fade in on the clip, which I've done. In fact, I have the first second of the clip at 0%, so it's not that. This happens on any clip. I'm running Dante ASIO at 48k, and all files are WAV 16bit PCM. Crossfading an audio file with another will give me the popping too. (On the same channels.) If I put a put a pre-roll above 3 seconds, it seems to do it at the beginning of the assigned pre-roll. Anyone know if this is something that's WO related or Dante related? It's pretty annoying. Also does anyone know how default DVS to 48k instead of WO assigning it as Auto? Auto doesn't work. We have a network switch that occasionally has to go offline, and it kills the DVS service. Trying to walk someone through how to reassign this on phone tech support is annoying. Quote Link to comment Share on other sites More sharing options...
Benoit Posted December 20, 2022 Report Share Posted December 20, 2022 Hi Quinoft, With DVS it's mandatory to select sample rate in the Watchout player audio out menu. Did you try to increase the buffer size in the DVS interface? Good luck. Benoit Quote Link to comment Share on other sites More sharing options...

That it goes back to Auto every time is frustrating. I'll be honest, I'm an idiot when it comes to audio things. Would the buffer size help minimize pops? Is there recommended ASIO settings for WO?

Benoit Posted December 21, 2022 Report Share Posted December 21, 2022 Strange, on what hardware do you have this issue? Watchout write somewhere the settings and is not supposed to lost it… Yes, increasing the buffer size might have a positive effect to reduce audio pops. Basically there is a buffer of data between the application and the real audio output. The smaller it is, the less delay there is between the app and the real audio output. Which is something good on DAW, when you’re a musician and the delay of the system might conflict with real instruments or other sound processors. For audio playback, delay doesn’t matter, because a “big” buffer is something like 4096 samples, but there are typically 48 000 samples per seconds. I’ll let you do the math, but you may delay the audio by 1 or 2 video frames… Not noticable. On another side, a small buffer requires the app to fill the buffer more often and when you have other highly CPU intensive things to do, your system might not be able to do it as often as required. It’s way easier for a computer to do it less often and fill a bigger buffer. Short answer: For Watchout, set the audio buffer to the maximum possible value, you will not have visible downside. Hope this helps. Benoit Quote Link to comment Share on other sites More sharing options...

Hope this helps. Benoit Sorry for the delayed response. I've been out a bit for the holidays. The hardware is a brand new Showsage PC that's integrating with a Q-SYS system handling Dante. I don't remember what speakers are being used, but they're definitely a Prosumer product. I believe they're JBLs. Thanks for the suggestions, I won't be back for a few days, but I'll see if the buffer manages to fixes anything. Quote Link to comment Share on other sites More sharing options...
