There's not too much clicking when nothing's going on but fastloading, using the menus, or using other programs in the background makes it more noticable. I also get occasional framedrops down to 47fps or so which cause audio dropouts.

Actually I just tried testing again and the silence detector does help by setting the level at the default 0 value when nothing is playing. But typing or playing music do cause clicks.
Thanks
But what I really need is:
-Disable silence detector, I don't want to have it enabled. Reopen the emulator if the setting was enabled
-Volume at 100%
-Select machine 48kb
-Just don't press any key. Just listen. Is there any continuous clicking audio? Or not?

Cheers

OK, I tested it and there is no clicking. I only start to get clicking noises if I switch to other windows in the background.

Hi @chernandezba

I've made three recordings which I hope will be of assistance. I can confirm that the silence setting is enabled.

ZEsarUX - PowerUp.mp3 - Shows the handful of clicks that you get when you first start the application with the 48K ROM. As mentioned earlier this is greatly improved now and I don't now consider this to be an issue.

I appreciate you said that you are not looking at audio distortion currently but this may help in the future. I have recorded 15 or 20 seconds of Dan Dare in Fuse and ZEsarUX

DynamiteDan - ZEsarUX.mp3 (Recording started then the file opened)

DynamiteDan - Fuse.mp3 (Recording started then the file opened)

All the files are here.

If we can help with any other testing please let us know.

If other want to record audio then I recommend Total Recorder. The free version lets you download one minute of audio which is fine for my needs.

Thanks Peter
I’m going to hear them

But as I said, I need you to test audio having silence detector DISABLED, not enabled. Forget it by now ;)
Thanks

I’ve heard them

I know about the power up sound. It’s related to high cpu use at startup, although I haven’t tested it too much

About comparing with Fuse... there’s no point on doing that. ZEsarUX plays audio at 15 kHz, 8 bit. It has less quality than any other emulator I know. It’s easier for me (15 kHz is the same scanline frequency in speccy) but poor quality. I know that ;)
Also, Fuse adds some audio filters to the playback, and I don’t do that either

About distortion... well anything can be improved and I will do it, if I can ;). I have a lot of things on the to-do...

I have added an additional file to the folder:

ZEsarUX - PowerUp & Load Game - Silence Detector Not Enabled .mp3

Thank you @chernandezba

I will delete the files from the server in one week.

Thanks. Perfect, only the startup “clicks” and nothing else
Just to be sure... did you recorded that in Windows?
