Trying to be more "scientific/objective", I took my other LG G2 d802 on stock with the LG stock app running whilst out walking together with my CM11 d802 - 2 pairs of the same headset (HTC Desire type are the dog's conkers for FM reception) one ear with Spirit and the other ear with stock LG FM. Quite a reasonable comparison and eliminates signal variation and propagation funnies. Significant difference... On the walk back, I tried Spirit2 in one ear and Stock in the other. Very similar, but appeared better than Spirit with less muting. That may have been my new relative position to the transmitter though, so not overly conclusive.

You have TWO d802s, one stock and one CM11 ?? Good opportunity to test...

If this is just a soft mute issue, you should be able to test them next to each other. Tune a strong station and verify/adjust so volume is the same. Compare RSSI, though the OEM API will use some different scale.

If you now tune both to a weak station, I'd guess one should have much lower volume.


Do you see "BC OEM" flash at startup on stock ? Does Spirit show the problem with BC OEM, but the stock app on that phone doesn't ?

(I fell lucky with a 2nd G2 in mint condition that someone had allegedly "bricked" and sold it me for a pittance. It took 15 minutes to sort. One of my daughters now uses it (so I only have minimal access to it now)).

BC OEM doesn't appear on CM11 or Stock as far as I can see.

Weak station-wise, and with lots of moving the headset cable around, the Stock app keeps the volume the same - no muting happened. Stock only seems to mute when searching for stations. Spirit2 on the same channel can be made to constantly flip the volume up and down as the signal drops to single figure RSSI. I tried to record this but for some reason I can't find the recorded file on the SDcard.

The stock app doesn't show RSSI.

I'm going to try Spirit1 and 2 on forced mono on tomorrow's outing and see what behaviours I get. I'm assuming that forced mono occurs in the FM front end and not in the audio path.

I think that if the soft mute can be disabled, and Spirit2 could have the pseudo-"Analogue" option (or the occasional audio pops/clicks eliminated on Digital) then the app would go from pretty acceptable to a very good solution.

Just wanted to add that I have Spirit UL working on an Xperia V (LT25i) using the most recent AOKP Kit-Kat nightly, from 20140216. Method is Digital QCOM OneXL/S/Sony/MoG.

I may have had a glitch with audio on phone calls after listening, though. A couple of hours after installing and getting it to work, I got a phone call and neither the other party or I could hear each other. Toggling speaker or mute did not work. Then I rebooted, and phone calls worked fine.

Glad, though, to have it back! Cheers, Mike!

The app popup message is correct.

Root is needed for HTC One GPE FM. AND so far Bluetooth must be off.

No way around these restrictions.

Google doesn't want us to have FM.

Digital Radio, the "Euro Chip Initiative" and "The Universal Smartphone Radio Project"

Was taking a "break" today and decided to check up on the latest news about Digital Radio (DAB/DAB+/DRM/HD/etc) and the NEW (& improved, LOL) efforts to spread digital & analog radio on smartphones via the "Euro Chip Initiative" and "The Universal Smartphone Radio Project".

My quick conclusion is that it's all doomed, as much as I'd like that not to be true.

The markets seem to indicate that efforts to promote digital radio are largely unsuccessful. There are some country markets doing better, but analog FM radio is still king, and rumors of analog shutoff in a country or 2 have no substance.

Basically, the proponents of digital radio are promoting it with "always upbeat" marketing messages, and almost no consumers are actually buying it. Now they seem to be "attacking" 4g/LTE/etc delivery methods as inefficient, which may have some truth, but it doesn't matter if nobody is buying it.


The "Euro Chip Initiative" and "The Universal Smartphone Radio Project" are trying to promote hybrid analog/digital radio chips in smart devices, and standard APIs to access them. Sony/ST-Ericcson started an effort to get a standard Android FM API at least 4 years ago. And it went nowhere and it's dead. I see no reason why new efforts would succeed while old ones failed.

IMO, it would be GREAT for me if these efforts bore fruit. I wish them (and myself) success. But I have no reason to expect success.

I hesitate to be "too full of myself"/cocky, but I think there's a good chance that nobody else in this world has had more experience with a wide variety of FM chips and APIs in use on the most popular (by far) smartphone platform of Android. I've become experienced in somewhere around 6 high level APIs and 6 low level FM APIs (I lost track, LOL). And on several generations of chips, Android versions, phones, ROMs, etc. Even the devs working for Samsung etc, only see Samsung phones, and likely have dealt with a more limited number of chips and APIs.

So, where the heck is this API ? And, given my experience, I'm feeling like it's hard to take seriously any attempt at another proposed standard FM/radio API, when nobody has even sent me an email about this. How many other written from scratch FM/real radio apps are on Google Play ? (Yes, there are a few minor ones if you dig deeply past the thousands of streaming apps.)

I've read that these people want to create an API for the hordes of developers who don't have an API to write to and don't want to deal with the minutiae of radio/RDS/etc technicalities. So you'd think they'd want to get feedback from devs. But I haven't heard from them.

Silence can be deafening.


So what's the future of radio ? In smartphones, I don't know. I have little idea of what deals will or will not be made, or how well they'll go between broadcasters, chip OEMs, phone OEMs, and all the other parties, including Google, Apple, MS, etc. Sooner or later, my little niche might be too small for me to continue. Hope not, but nothing lasts forever, and we'll see.

As far as radio broadcasting goes, I continue to think analog FM has at least 10 years of life left, maybe 20, and more so in less connected parts of the world.

And I think digital broadcasting will continue to limp along.

And the use of streaming services will continue to rise, particularly for the richer people and countries. 4g will give way to 5g and 6g etc.

Basically, I think the trends in place will continue. And no amount of hand wringing or proposals for hybrid chips or new APIs will go anywhere. The only things that matter will be the "votes" of countless people as they buy phones with or without usable analog FM chips (and standalone radios). Technology has to be PULLED by masses of people spending money. It can't be PUSHED.

The successful transition of TV from analog to digital does not translate into the same for radio.

Xperia V I have little or no feedback on,with only 5 customers.

You can use Debug-> Power Restart Media to reset audio at FM off time.

Um, the post about Digital Radio, and all that . . .

I suspect that Digital Radio and Spirit both suffer from the same problem: a technology in search of a customer.

Customers want convenience (since we all think we're time poor) and content (we worship the One God, of competition); then some of us worry about quality and like a challenge. Digital streaming gets 3 out of 4. Spirit and DAB and its variants probably get about 1 out of 4. I'll leave you to sort out which.

DAB's biggest problem apart from coverage is that it never took off in cars, and for choice, quality and convenience is now supplanted by streaming. As one would expect really by a Government-mandated system, with a marketing budget in search of a product.

Spirit's problem IF your phone has FM, and IF you want an app instead of or in addition to that packaged, and IF you're willing to pay so much for it, and IF you can put up with the audio let alone IF FM meets your needs and IF you can get it working and keep it so and UNLESS you want to play with it rather than all the other things you can do with your phone ... so many IFs. Smartphones aren't made for FM. I'm a fan of both FM (but for a small specialised part of my listening) and of Spirit (when it works as it should), but I have no illusions that I'm part of a miniscule minority (of one, perhaps?).
