[Poweramp Equalizer builds 899-908]

@maxmp OK, thanks for the reply.

@maxmp Is the Parametric Equalizer IIR (Infinite Impulse Response) or minimum phase?

[SoX resampler advanced settings]

SoX resampler include many settings aside from bandwith and dithering, such as VHQ SRC, steep filter, phase response and anti aliasing. Since resampling oftenly takes place, could you please consider including all the sound settings SoX has to offer? That would give more control over the sound quality and signature. Thanks in advance.

@Romain1998 sorry, I though the issue was the sample rate. Now it's something related to the volume? Poweramp may change volume slightly (+/- 1) for few seconds after the BT connection if "No DVC For Absolute Volume" option is enabled. This is never more than +/-1 and not generally noticeable. There is no other way to check for the Absolute Volume as Google bugged everything related to it in the recent androids (looks like new team works on BT stack and they just keep everything they don't use/test in broken state), but if you know you have Absolute Volume disabled, you can just disable option "No DVC For Absolute Volume" to avoid any volume changes. Android still will restore some previous volume for the Bluetooth + the BT device may also have some other volume level.

@maxmp Actually, it's when the Bluetooth Hi-Res output sample rate resets itself to 48 khz that the volume also starts to automatically change. This makes the issue even more annoying. I don't think it's related to the DVC though, since I don't have it activated.

@Romain1998 I use task management tools. Bixby Routines free on Samsung devices is handy, you can set it to apply certain volume levels when you connect a specific Bluetooth device, and set them back again afterwards.

@andrewilley Right, thanks for the tip, but can you fix it?

@Romain1998 Poweramp follows system here, ensure you have ldac working for 96khz.

@maxmp I didn't precise it, but when the sample rate resets itself to 48 khz (for instance, when Poweramp is not playing any sound, working in background and then used again), the volume also automatically and drastically increases and decreases up until I pick another sample rate in the app.

Sometimes, when I forget about it and I'm using my headphones, it catches me by surprise and hurts my ears. Please, could you do something about this? It's really irritating.

[Poweramp builds 899-905]

@maxmp In my case, I don't think so, as these screenshots suggest.

[Poweramp builds 899-905]

The sample rate in Bluetooth Hi-Res output keeps on resetting itself to 48 khz. Could you please fix it?

[768 khz output]

@░▒▓█ クリス █▓▒░ I don't pretend I can hear the frequencies, but i might hear a more natural and proprer sound.

[768 khz output]

@andrewilley No, I'm Batman lol. Jokes aside, because it might make sound more soft and natural on DACs which support it.

[768 khz output]

Hello, i was just wondering if you could please add 768 khz output. Thanks.

[Requests for Hi-Res Support (please state which build of Poweramp you are using)]

Hello, I was just wondering if you could please allow 32 bit output on the Xiaomi Mi 9T Pro. Thanks.
