Bluetooth Will Support Hearing Aids, Sharing, and a Better Audio Codec (theverge.com) 84

Posted by BeauHD from the new-and-improved-features dept.
An anonymous reader quotes a report from The Verge: Now that most smartphones don't have headphone jacks, there's no shortage of complaints about Bluetooth. This year at CES, the industry group in charge of defining the standard, the Bluetooth SIG, is introducing new features that should address some of them. Later this year, it will finalize new support for Bluetooth LE Audio, which is an umbrella term for a bunch of new features for Bluetooth devices. The new features include higher-quality audio, hearing aid support, broadcasting to many people, and working better with wireless earbuds. Unfortunately, as is the way with all industry specs, it will take some time for these features to make their way into consumer products. The old joke that "Bluetooth will be better next year" still holds true.

The feature that will likely affect the most people is the new "Low Complexity Communication Codec," or LC3. LC3 simultaneously reduces power consumption while increasing audio quality. Right now, the lowest common denominator for Bluetooth audio is the relatively old and relatively bad SBC codec, though many phones support Qualcomm's proprietary codec, AptX. In order to get SBC to sound good, you have to increase the bitrate, which increases power consumption. The Bluetooth SIG claims that, in its testing, users preferred the new LC3 codec, even at significantly lower bitrates. The group is also finally beefing up official support for Bluetooth hearing aids. It has worked in conjunction with a European hearing instrument association to ensure broad support in the coming years, including working with TVs and other devices. A new "broadcast" feature will theoretically allow an entire movie theater audience to use their Bluetooth headphones to tune in to the movie, although how exactly the pairing process would work is "TBD," the report says.

Bluetooth LE will natively support multistream audio, which "means wireless earbuds will be able to receive their own independent signal from a phone instead of having to communicate with each other," the report adds. "Multistream also will allow for easier sharing of Bluetooth audio among multiple users from the same source."

      Maybe not for you.

      But how about the hearing impaired, who need a hearing aid with a custom-programmed DSP to render the sound into a sensation corresponding more closely to what a person with normal hearing would get from the air in the theatre?

      Or how about the people who'd rather hear the movie than the raucous theatre-goers and their cell phones. For them those $200ish noise-cancelling phones might just sound a bunch better than a theatre sound system of any price. (Also: They'll still benefit from the theatre's woofers and sub-woofers, which will do a dandy job of giving them the feel of the sound.)

      With enough channels and a 9-axis (3-linear, 3-twist, 3-compass) MEMS gyro/accelerometer/magnetometer the phones might give a much better surround effect, too.

        I'm not so sure how well noise cancelling headphones will work, because the outside sound material is the same as what's trying to be heard inside the headphones. Might cancel itself out. Depending on how far you are from the speakers there will probably be a spot in the theatre where the sound in the headphones is in phase with the sound from the speakers and may end up confusing the noise cancelling process. Or not...

    Here's how it works. An new international standard is established though one of the standards bodies. These are non-profits and are supported by governments and large companies for the "greater good". It's expensive to participate because you have to go to meetings held all over the world for a period of years.

    All the new technology used is given to a Licensing Authority by the committee members. Existing technology is "encumbered" so it isn't used, and the new stuff will be so much better!

    After the standard is accepted no one can legally use it without getting a license from the License Authority. They divide the revenue stream between the various participants.

    It's an international technology cartel masquerading as a international standard.

    The license fees are typically the dominant cost passed on to the consumer. That's why HDMI cables are not cheep.

        I want a set of headphones I can pair to my phone, my laptops, etc, and be able to sit down and have audio from them simultaneously. When I hear my phone's ringtone, I'll just pause my laptop audio or vice-versa, and not have to fuck around with clumsy pairing/re-pairing.

        That's exactly what the new Bluetooth specification is designed to do. You will be pleased.

        The lack of the ability to pair multiple listeners to a single transmitter has always been an annoyance (I mean it's a fucking radio transmission, right?). Why can't you have one phone playing on 3 different bluetooth speakers at once?

        For the following reasons:
        (1) -- Prior to this release, Bluetooth did not have a true isochronous (occurring at the same time) audio feature. There was no way to ensure that receiving devices would play a received audio packet at exactly the desired time -- especially if the receiving devices were not identical. Having three speakers produce audio at substantially random phase delays is a really terrible listening experience.
        (2) -- Wireless transmission is not perfect; even on a "good" path as many as ten percent of packets sent to each speaker are lost, and must be resent. The prior Bluetooth system did not have a scheme allowing a single transmitted packet to be independently ACKed by multiple devices (without interfering with each other) and, when an ACK was not received, resent. Note that time had to be set aside in the protocol for all this physical-layer stuff to happen (i.e., the worst-case number of retries sent) before the scheduled audio packet presentation time. This is especially difficult around the human body; the path loss from a back jeans pocket to the ear on the opposite side of the head is incredibly large, and the path loss from ear-to-ear is almost as bad. (The worst case, BTW, is the proverbial corn field, with no reflections from nearby walls, etc., which actually help a bit.)
        (3) -- Security and privacy are non-trivial. For example, you might want music from your phone playing to the external speakers, but not phone calls from (or to) your boss. However, if you're at home, and the call is from Grandma, maybe you do want the rest of the family to hear the call. Making the expected behavior both bulletproof and easy to use was not easy in earlier releases.

        It's kind of dumb the bluetooth standard got to this point without someone figuring out how to make these things happen.

        I agree that Bluetooth is at least five years late on this feature -- you won't get any argument from me on this point. In their defense, however, Bluetooth was originally designed to be a replacement for the desktop PC-to-printer cable when it was first released in 1999. Moving the specification from file transfer to isochronous audio, while (substantially) maintaining backwards compatibility, remains a nontrivial feat.

        • Security and privacy are non-trivial. For example, you might want music from your phone playing to the external speakers, but not phone calls from (or to) your boss.
