Hi! I'm one of the guys working on that project, and I can already tell you it's going smoothly :)

We have a few effects already working (although some extra work will be needed to check if they are 1:1, any small change in the code can lead to huge changes in audio quality).

My initial goal was indeed creating a 64 bit version of it, and also removing the need for pathing selinux (and yep, i was able to achieve that, no selinux patches needed amymore).

Overall it's looking good but I don't own a Pixel 7 Pro so I'll need some volunteers to test it once it's ready :)
I'll test.
I've been an adamant fan of V4A for years and literally only purchase phones that are rootable for this one app. If I had any idea that the P7P want going to run V4A out of the box, I would've held on to my OP7P a little longer.
But, here is my reason to live my new P7P! I will GLADLY test.

Pm me the telegram or whatever, I'm in.

Same. everyone always asks, "you still root your android? Why?" I always reply with "viper4android"

I'll be happy to test it on my Pixel 7 Pro if you want

Awesome news! A question I always wanted to ask to someone on the V4A development. Will V4A process data sent to bluetooth headphones as well? My understanding is that the data is just streamed to headset to be processed and enhanced by the headphone chip and hence would by pass any phone equalizer.

but I've seen a change in effect when we enable v4A, so curious to know how.

Having similar struggles installing V4A on my S22U snapdragon variant - Keep getting install drivers loop every time I open V4A app (even with SElinux permissive kernel).

Eagerly awaiting v4a update/ resurrection & happy to try out any betas/ help.

I use jamesDSP and amazing!!!
I tried JamesDSP the other day and I thought it was really terrible. It's probably that I'm not using the settings correctly but I tried a lot of different combinations. I would toggle the main 'power' switch on and then off while listening to music. I found that I could hear way more with it not engaged, so I uninstalled it. But if someone wanted to share their settings, I'd be willing to give it another go. I was a huge fan of Viper4Android.

I'd love to test. Please let me know how I can help.

    So it works on speaker but when I try to play through my buds pro then it won't process.
    Try disabling LDAC.

    A possible light at the end of the tunnel is this project, they are aiming to reverse engineer Viper and modernise the files (hopefully that means using x64!). We'll just have to monitor the progress....

    Hey! Quick update, I released an alpha build, you can find it here: https://github.com/AndroidAudioMods/ViPER4AndroidApp/releases/

    It's just a test build, many things won't work, the app might crash if trying to load a preset, etc. Follow the instructions in the release to install it. Do not use any other audio mod, no AML or anything.

    I use wavelet and it works really well. Always had trouble getting v4a working

    thanks. downloaded jamesDSP and works fine. How can I get the best sound settings? Do you have any tips ?
    There really is no such thing as "best" sound settings. Sound is very subjective. What sounds good to one person may sound bad to another. Also, music genre plays a roll in how you set your sound up, as well as the type of device you are listening through (e.g. one brand/model of earbud will sound different than another and therefore adjustments will have to be made to that specific earbud).

    Best is to just play around with the settings until you come up with something you like.

    V4A doesn't currently work on the Pixel 6 or 7 series running stock Android 13. Some have said it is working on the Pixel 7 Pro running the Corvus rom.
    I can confirm, I have it running on my Pixel 7 Pro with Corvus. No issues with Viper repackaged.... and the sound is fantastic ;-)
