[MOD] Nokia Recorder with OZO support

[back.rider555]

I ported a few codes into the Nokia Recorder app v8.1030.40 to enable support for OZO audio recording. I've only tested this in my Nokia 7 Plus, but it might work in other OZO-supported devices.

Changelog:
- Added spatial recording support: ACC recording format (screenshot 2) now records with spatial audio recording by default.
- Changed app theme color: just to differentiate it from the original base app.

NOTES: To make the most of the spatial recording feature, I forced Surround mode in this mod, which means all three microphones are used at once. Since this feature is for video recording by default, its full potential can be maximized in landscape mode (since the microphones are oriented vertically, putting the phone in landscape mode allows for differential left and right audio channels). Here, I forced the orientation such that the left audio channel is oriented at the top portion of the phone, and the right audio channel at the bottom. So for accurate audio channels, I recommend orienting the phone in landscape mode with the charging port on the right hand side (like recording a video). Of course if it doesn't matter to you that much, you can orient the phone however you like; audio quality is good, nevertheless. Enjoy recording audio in high quality!

P.S. I humbly request everyone to please do not spam with "add the feature/support to GCam" etc. etc. I've spent 4 days to figure this out and make it work, and I need a break right now. Cheers!

When this device was released, my PRIMARY purpose to buy this phone was to use OZO audio to record songs !!!
THANKS A LOTT !!

Why does it require phone permission?

Why does it require phone permission?

This is to pause recording with incoming phone calls.

Thank you very much, this will be very helpful because most recording apps doesn’t utilize Nokia’s ozo audio. Nokia microphones are awesome!

I'm curious how you figured it out. Is there some Nokia API documentation somewhere or is it just a matter of enumerating device capabilities and trying the various options? Is is an Java API or do you need to call ioctl on some device?

Would you be able to post a code snippet?

Can you upload ozo video recorder
Please

Can you upload ozo video recorder
Please

It's stock Nokia camera ??*

Thanks for the great work and for sharing. Installed fine on my Nokia 8. Will do some test recordings and listen with headphones, the only way to really enjoy spatial audio.

I've been looking for some way of recording Ozo sound since I got my Nokia 8 over a year ago. Up until now I've had to record video as well using the camera app, then extract the audio in Audacity.

I had written to Nokia back in September 2018 and had this reply:

Hi Mark,

OZO Audio function on the Nokia 8 is only for native camera video recording function and not open to 3rd party applications. Please contact mobile phone division for any further questions and support.

Regards,
OZO Sales


I'd also written to the author of the Hi-Q app to see if he could get Ozo audio working, but he couldn't. The audio recorded by other apps had odd audio distortion present as if some algorithm was at play distorting everything.

I'll do some testing later!

You said you could configure the microphones. For the Nokia 8 it might be useful to use the bottom mic and the one on the screen side then you can leave the phone placed on a surface and still watch the recording.

Can you explain what you've done... I can let the Hi-Q app developer know!

Thanks,
Mark.

Yes my phone stock Nokia camera app

With further tests on my Nokia 8 I can see the microphone by the screen doesn't seem to influence any of the recordings. You can rub it or occlude it and the stereo field doesn't shift. If you rub the mic near the flash or near the USB socket you hear mono noise (equal in left and right) added to the recording. If you occlude either of these you get mono recordings and signal is equally split between left and right. If you occlude both mics everything goes very quiet and muffled. If sound reaches both mics then it successfully puts the recording in the stereo field. As rubbing sounds are noisy in one mic but probably not heard in the other the Ozo algorithm probably sends that equally to left and right channels as it can't tell where it is coming from. There is no audio distortion heard on recording music coming from a room TV. With my Hi-Q app, rubbing either of the same mics generates noise purely in the left or right channel. And that app still suffers from some very strange audio processing where music in the room seems to get signal processed away.

In short, this is the app we've all been waiting for!

 

[webvan]

Thanks for your detailed feedback. Where is the "screen side" microphone located ? Based on the notes that came with the app "forced surround", shouldn't it also be used by the app like in the surround mode of the videos produced by the stock camera app ?

I videod a piano concert the other day and while the surround sound sounded better than the "front" option I was a bit annoyed by the "shifting" in the sound, probably due to the OZO software interpreting the sound sent by the mics.

The third mic is to the side of the ear piece, in the glass cutout line (on the Nokia 8).
