(Android) Crackling sound during playback of GBA gsf files #2185

Closed coderkei closed 3 years ago

coderkei commented 4 years ago

On the latest release version for Android (b4971 thin), during playback of Gameboy Advance GSF files, a noticeable crackling sound can be heard. It seems to happen for all the GSF files I tested for various games. This did not occur before the latest update where the fade options were added. I currently have fade in and out disabled.

I have tested various GSF files for games including Pokemon Sapphire, Yu Gi Oh GX Duel Academy and Sonic Advance 1, 2, 3 and the music for all them has a weird crackling sound that I didn't hear on the previous version.

Device is an Oppo Reno running Android 10. Build info in the app says arm64-v8a normal long port.

I have tried the latest r4980-thin version and unfortunately the same issue still occurs. Any ideas on a cause?

Do you have another devices to check out?

I tried on my Xiaomi Redmi 9A too, running Android 10 and it has the same issue on build 4980.

I played Littleroot town from Pokemon sapphire as that seems to show the issue well. The crackling resembles vinyl record crackling you could say.

I was trying some older APKs on both devices too and it seems on build 4960, the issue does not occur on either device.

Looks like I've found an issue. I may share fixed desktop version. Can you check it out?

coderkei commented 3 years ago

Sure, is it for Windows?

vitamin-caig commented 3 years ago

You may compare it with one from public build. zxtune123.zip

coderkei commented 3 years ago

Okay, I tried the build you sent me and then compared with the latest public version from https://zxtune.bitbucket.io/.

The latest public version has the crackling, while the build you linked above seems to have that issue fixed and no longer crackles.

Excellent! So fix will be available in the nearest release.
