Sound / audio latency & static

Postby jknut » Fri May 16, 2014 1:57 pm

I'm getting static noise when I play Radiant Historia especially when it's raining. Setting it to Very High latency helps... but is there anything else that I can do?

Desmume has "synchronous" audio mode which is perfect. Is there something similar for DraStic?

The synchronous setting in DeSmuME isn't related to this, the audio normally works like that here (sort of anyway).

Some devices just have a lot of audio lag and only work with higher latency settings, which is why the option is there. It can be big problem with Android. Are you using a Bluetooth headset or some other kind of external audio? That can add more latency.

The static will happen at either low or medium latency on phone speaker or bluetooth on my Galaxy S4.

Is there anything else (phone settings, ROM trimming, DraStic options, etc) that I can try to get better audio quality?

Or can the audio in the NDS file be edited in some way to help?

Hi guys,

Just purchased this great emulator but there is a terrible sound lag on all games. I'm running this on Samsung galaxy s9 plus. Any ideas??

Some OEMs, especially carriers, ship their devices with heavy custom roms. Disable safe to disable bloatware apps from your device. You maybe able to find a complete list for your device over at XDA android hacking & development.

Turn off keep wi-fi on during sleep, location's wi-fi & bluetooth scanning during sleep, & scanning for printers. When uneeded turn off location, bluetooth, & mobile hotspot.

You're welcome to activate developer options. By going into settings, all the way at the bottom enter about phone, then bottom again & tap build number 7 times or until the toast message confirms them activated. Then back out of about phone. You should see developer options have been added to your settings menus. Enter it, then enable it. Set logger buffer sizes to the smallest amount available. Off if you can. Turn on force gpu rendering. Optional: turn on disable hardware overlays. Disable hw overlays will have to be set on again if the device is turned off or restarted. Don't mess with anything else in there unless you're absolutely sure of what you're doing.

Optional: Turn off battery saver mode & set brightness to 50% instead if you want to save battery without decreasing performance. Make use of device performance toggle's like Game Mode. Set Game Tuner fps to max, try the lowest resolution. Other devices will have something similar like Game Battery Saver. Which will work even with Battery Saver mode turned off. Close apps running in the backround to free up ram for heavier use like gaming.

Bluetooth has higher latency than wired. Change options in audio set DraStic's audio latency to very high. Optional: In general turn off enable lua. In advanced enable auto trim rom & use low-res ui textures. Optional: In video enable multi-threaded 3d rendering & set frameskip to manual at 0, or auto at 1 or more. If none of that works, try 16-bit rendering, disable edge marking, & set frameskip to manual at 1 or more.

Restarting your device can free up fragmented memory. Android devices compute in ARM's big.LITTLE core cpu architecture. Big cpu cores shut down at low battery % & the little ones take on more of the workload. Gaming during charging becomes bottlenecked from overheating & cpu throttling safety measures.
