Normally the phone frequency is limited, ranging from 300 Hz to 3,4 kHz. Using the AMR-WB codec, speech is transmitted from 80 Hz to 7 kHz.

See: https://en.wikipedia.org/wiki/Wideband_audio

If Ubuntu uses the android GSM/UMTS/LTE driver from android (and the driver supports the codec), does wideband audio work in Ubuntu's phone app?

I just searched the entire source repository for Ubuntu Touch for "AMR" and there is nothing in there that suggests AMR-WB is used, so the simple answer to your question is: No.

Sorry to be the harbinger of bad news…

    Thanks, great idea. I'd like to file a bug report about the issue. In your opinion, what is the correct package to file the report?

    The package exists, so it just needs to be included in Ubuntu touch: packages.ubuntu.com/search?keywords=libopencore-amrwb-dev

    Also: you've still got 6 days... Maybe a developer will walk in, see your question and do it for you... You shouldn't accept my answer (yet)! ;-)

HD voice aka wideband audio works. Confirmed with a Meizu MX4.
