DAC on phone - Lenovo P2 Questions & Answers

Hi, first, sorry for my english, it's almost certain that I will mistake some words.
I've read different info about the presence of a internal DAC on the phone, for example poweramp don't see anything for the hi fi option, but on google many people talk about a internal dac for a hi fi quality.
So, is it present or not?

The phone has a 3.5mm jack, so it has to have an internal DAC.

No there is no hifi dac on this phone.

The P2 has a Snapdragon 625 processor, the following is listed on their advanced spec sheet.
Qualcomm Aqstic™
+ Crystal clear VoLTE w/ Ultra HD
Voice (EVS)
+ High fidelity music playback
24bit/192kHz
+ Dolby 5.1 support
Built-in Qualcomm Aqustic central audio processor with Lenovo configured Texas Instrument TAS2555 SMART amplifier, providing the ability to play audio files up to 192 kHz / 24-bit. Sources here, here and here.
Looks pretty good on paper, but the DAC really isn't that good.

TV Out via 3.5mm Audio

I know it has been asked before over here, but i would like to discuss it again:
Could it be somehow possible to activate TV-Out over the 3.5mm audio connector on the defy?
The Samsung Captivate (aka Galaxy S) has it and the devs managed to support it in their CM7 version for the captivate. Perhaps we could use some of those "drivers"?
It would be just to cool to use the defy with a bluetooth keyboard (apple wireless keyboard working flawlessly btw) and a nice big screen for browsing and writing documents...
Btw the cable looks like this.
i dont think its matter of drivers, if the headphones jack is not wired to give tv output, then it wont be physically possible without a hardware mod... just my opinion, i could be wrong tho...
Indeed. If it's not meant to output video then it's not meant to. End of story ^^

Did anybody proof that its not wired?
At least it can give audio over 3 pins (stereo+mic) - that means all contacts needed are wired. COuld the tv-signal perhaps be "disguised" as audio signal?

Do you really think that motorola would put a video-output capable 3,5mm jack in the phone, and not use it as a feature?? Things aren't free in this world. If there was one, they would have said so, simply because...they could sell more Defys thanks to it.
Putting a really awesome feature in a phone and not saying nothing about it? Come on... xD
In addition our phone isn't event meant for tv-out, forget about having it flowing out of wierd places like an audio jack x)

Do you really think motorola wouldn`t open the bootloader even if they could? They could have sold a few defys more with an open bootloader....
You might have noticed that im not that convinced by your argument.
No **** man. Moto also advertised a gpu less omap 3610. When in all actuality we have omap 3630. Why would they do that? I think this deserves more looking into
Sent from my MB526 using XDA App
I think if it would be possible, chances are that a kernel tweak would be needed to activate it and thus it would not be possible with a locked bootloader.
But still, i think it could be worth it to take a look in the Captivates librarys regarding tv-out.

Motorola wouldn't have significantly more sales if the bootloader was unlocked: over 80% of consumers don't even know what a locked/unlocked bootoader is

Can the hdmi / vga tv out be sent via USB?
Please dont be naif, you know how much motorola lies about the defy!, i did a search about the defy hardware, the chip as you know is an omap3630 with sgx530 and IVA 2 +, this chip is capable of transmit audio and video, see the pic:
b.imagehost.org/0148/tiomap.jpg
So the probem is software related, maybe its too complicated due to the locked bootloader but i think its totally posible, its just a matter to find some device that uses the same chip, like the Droid x or milestone 2...

not really... we all know the chip is capable, but if it is not physically utilized, no amount of software tweaking will make it possible... i dont think they would have bothered to connect the 3.5mm audio jack with video out if they are not going to use it...
but u r asking the right question... think outside the box, if its even remotely possible, i would like to have this feature
Following your argument i would conclude that it MUST be possile to route a video signal through the headphone jack. Of course you would need a software wrapper which codes the video signal and puts it out as a sound. If you would do that as an app, this might be awfully slow. But i cant see a reason for this to be impossile as the headphone jack IS wired to the sound output and apps ARE capale of using that sound output.
I would really like to use an app like that as a workaround, as long as its fast enough for simple rowsing.
Edit: I just searched the marked for "Image to sound" apps and came across "Spectral" which takes an image, converrts it into a sound spectrum and plazs it. It should not e too hard to change the conversion to conformwith the component video standard.
This would still onlz convert one image and i dout it would be possible to use this with screenshots in realtime but it would be a good step towards video out on the defy.

Dude in fact, it is very hard/impossible. One thing is "transform" a digital image in a digital audio. In that case you dont need to make sense, just convert one block of image into one "la" ou "do" and you are good to go.
We have a limited range of frequencies that we can hear and software/hardware generally take advantage of that. Transport analogic video(that may take a broad range of frequencies) trought analogic audio hardware may be impossible for near anything apart form really simple scenes

High-Quality Audio Recording

I have a question for the developers (im not one):
Though the KF doesnt have a built-in mic, it supports an external one for audio recording. Ive been using Android devices for a little over two years, and have tried a number of audio recoring apps on them.
There are a number of stereo microphones available (from Belkin, Tascam, Blue, etc) that allow high-quality stereo recording on ipods and iphones. There are a number of apps available for recording on Android, but the quality of the recordings is not great. Why is that? Is there something inherent in the Android platform that does not permit hi quality recording?
Sent from my Kindle Fire using Tapatalk
This link might enlighten you a bit. Along with extremely poor audio-latency it would seem that audio recording is also problematic. Strange to find this in an audio device such as a phone eh?
Thanks; I actually used to use the Rehearsal Assistant app. I posed this same question to the developer of J4T, which is a very cool Android multitrack recording app, and I just got his response:
"One reason might be that the best recording quality that is supported by most Android phones is mono, 16-bit pcm, with samplerate 44100. So to make sure a recording app runs on most most android phones, the developer should probably use those numbers and not go any higher.
But it also means it's possible to have android phones that can record at much higher quality, and maybe they are out there. But that capacity may go unused, because the apps are developed for the 'average' phone.
Perhaps on other platforms the 'average phones' have higher bitrates and samplerates.
There are actually 2 ways to do audio recording on Android, but I'm not familiar with the other way (where you can record to AAC or AMR format). Perhaps the quality using those codecs is better than PCM, I don't know.
Please don't take this as a definite answer - this is just a guess from my perspective, maybe a manufacturer (or the Android team) would give a different answer."
I've been using a Belkin Tundtalk stereo microphone with a 3rd-generation ipod nano to make reharsal recordings of my rock band; the quality is actually very good. It records in wav format, stereo, 16-bit pcm, with samplerate 44100. So, outside of the fact that Android records in mono, not stereo, the potential for decent quality is there. The lousy quality must have a lot to do with the cheesy microphones used in the Android phones. If I could find a decent quality mic that would work with my Android phone (or with the Fire), I imagine it would make a big difference.
Yeah, from what I know about Android audio going the other way, the audio-latency issues, Google really managed to screw up on a bunch of levels. The audio app market on the iPhone is pretty big and they just haven't stepped up to the plate for developers from what I can see. I see a few apps coming out like AudioSketch that claim to have custom low-latency audio drivers, but that one isn't available for the Kindle Fire so I really can't say. But, sorry, I am digressing. I'd be curious as to see what results you get from your experiences.

This man doesn't now a thing about sound encoding. PCM is uncompressed audio format so it have smallest use of CPU and it has best quality. Only problem is that is space-hungry in comparison with other codec's.
In audio, whole system is good as the weakest thing in it. You need good MIC, you need good MIC input, you need good audio driver and you need good recording app. If one link in this chain is inadequate resulting sound quality is on level of that poor part.
Hey, just a thought but you might be able to turn your question into a free Kindle Fire if you were so inclined.

Now that you've brought it to my attention, I AM so inclined! That's for letting me know.
I posted my question there, and after about an hour it was Closed as "not constructive" lol.
As I said, I'm not a developer. Even before I posted the question here I googled the subject and haven't been able to come up with a definitive answer as to why this is so. I would think there would be a huge market for after-market microphones for people to use on their Android phones (as there is for iphone and ipod). If I was an iphone fanboy, this would be my first argument against Android - crappy audio recording!

Bluetooth HFP 1.6 wideband audio (HD Voice)?

It's lame that in 2016 we still have to ask this. Google was very late to the party to implement hands-free profile 1.6 with wideband audio. They just started with the N6 in late 2014, the N5 did not have it. But, the N9 does not have it, the Shield Tablet does not have it, the N10 of course doesn't either, so no Google tablets that I know of (haven't tried a 2013 N7 though).
If you're wondering, so-called HD Voice in bluetooth (not to be confused with the carriers' "HD Voice" which is a similar thing but within their network) is also called wideband audio because normally BT cuts out at about 3kHz for voice/talk. HFP 1.6 wideband doubles the bandwidth to about 7kHz so voice is much, much clearer.
Usually this is advertised for phones cause the carriers are implementing their own HD Voice, and you'd need a BT HFP 1.6 wideband headset to take advantage of that, but what everyone seems to miss is that pretty much all VoIP apps use a wideband codec, and those work great with these HD headsets.
So, if anyone is familiar with this, could you test it on the Pixel C? You'd need a HD Voice headset, of course. I know pretty much all Sony ones are (but for some like the SBH52 and BRH10 you have to explicitly enable it with an app), and most modern ones from the big brands. If you don't know how, you can make a hangouts-to-hangouts voice call from your phone, and listen to the clarity. (Don't use Skype though, I think its Android app while it does use wideband normally, falls back to narrowband for bluetooth.) There shouldn't be much difference between using headphones and using the headset connected to the tablet. If it's not HD Voice, you'll notice a big difference with the higher frequencies, especially the "S".

Hey Andy o
I have a Plantronics Voyager Edge with Wideband - I use it daily with my N6P on voice calls (GSM).
I'd be happy to pair it with the Pixel C and happy to try via hangouts, but no one I know uses hangouts anymore. PM me if you want to try and test this.
Seems that the pixel c has no hands free Bluetooth profile at all (not narrow band and not wide band). When you connect a Bluetooth headset the tablet pairs but doesn't connect to any hands free profile. It has A2DP for music streaming but if you were thinking of making voip call using a Bluetooth headset, forget it. Pretty lame for a $500+ device.

Hence why I returned it. This and the lack of auto correct when typing with the keyboard killed it for me.
I wonder if this is because of the rumors that it was designed for Chrome OS which, unbelievably, just got the HFP profile last July. If so, it might be available in future updates, and would support the notion that the software on this thing was rushed out.
Regardless of the reason, it is simply unacceptable that such a premium device being sold and a high price tag will lack basic features like this.
I'm sure most users won't use a headset with this device but for the price support for it should be included. The original nexus 7 didn't have it either. The second nexus 7 had it (lowband). The nexus 9 had this profile.
This is why apple is doing so well. Everything just works.
I don't even think "premium" comes into play. That any modern tablet or phone doesn't have it is nuts. I can't imagine a modern BT chip not having support for it, so it's probably a software/drivers issue, but who knows if Google will fix it.
BTW, are you sure the 2012 N7 didn't have it? I remember it not having a TRRS (headphone+mic) connector, which also crippled it for Square payments, and which was just as dumb a product design choice. But IIRC one of the workarounds was to use a BT headset.
Also, I don't think the N9 has HFP 1.6 wideband. The audio itself is just terrible in comparison with HD-enabled devices like the N6P, N6 and my iOS devices. Even using a frequency generator just to be super sure has it cut off at just above 3500 Hz which is expected for the narrowband profile. With wideband I can still hear on the other device up to 7800 Hz or so.
Yes I don't think the N9 had wideband either. As far as I can recall the N7 2012 didn't have HFP profile either as I remember it driving me nuts that I couldn't use a Bluetooth headset on it to make voip calls.
I went ahead and opened a thread on the Google product support for the pixel c and it has been escalated. Let's see what comes back and if they intend to enable HFP on this device or not.

I don't believe the Nexus 7s or the Nexus 9 have HFP support (low or wide). I can confirm the Nexus 9 doesn't, I couldn't use my bluetooth headset for voip calls via Hangouts. Here's Google's table with Bluetooth profiles:

I can confirm that the table is correct about the Nexus 10, I used Plumble and Hangouts perfectly with the same Bluetooth headset as I used above for calls.

I'll have to check my Nexus 9 with Plumble + Bluetooth then, only used it with Hangouts video chat and it worked great, but Hangouts Dialer calls to a phone number wouldn't work with my bluetooth headset.
Anyone here with the Pixel C on the latest developer preview? Can you confirm if they added Bluetooth headset support (hands-free profile)?
How can one check, which Codecs are used over Buetooth ?
On my Xiaomi Mi A2 Lite I can somehow enable under Developper Mode the APT-X and LDAC Codecs,
but how can I test it, if it being used e.g. in Skype for Android or other Voice Applications ?
My Blootooth Stereo Headset has Apt-X , but during Skype calls or a Wireless Video Recorder app, it still uses only the 8 Khz SBC bad audio codecs...
Any idea how I can test it and how to enable the Wideband Audio Codecs ?
Many thanks.
Regards., Stefan.
It has to support mSBC for handset:

An app like Bluetooth Monitor might show more info about the actual connection.

What do we get with 'aptX audio technology ?

I was trying to prepare for the Snapdragon 845 beast and the ( dang, dang, dang ) usb-c audio port.
There was a nice article to read at :
https://www.pcworld.com/article/328...e-jack-why-usb-c-audio-still-doesnt-work.html
I believe I read it right in that the pixel 3 is a 'active' dongle type. ( it's got a DAC ? In the plug ? )
.
The qualcomm doc doc says the audio on the 845 includes the addition of 'aptX' . . . I need to buy new stuff to take advantage of it ?
In the developer options you can change your audio codec to aptx hd. But I can never get it to stick. By default it says it's on the default. If I change it it shows it switched to aptx but then if I exit out of developers options then go back in it says it's using the default again.

Wrong. Where do you get your info.
When you play audio using an aptX/HD device then the pixel will automatically switch it to that codec. Whatever device you're using the phone will pick the best codec to use, it doesn't really matter what the default is. Same behavior as the 2.
Using Sennheiser HD 4.40 with the 3XL and I don't think I'll need to install viper on this device. Sounds incredible with some eq tweaking.
What he said.
It won't use the aptX codec until you connect to a device that supports aptX.
Aptx will deliver better highs and lows.
More solid bass, slightly clearer highs and better bandwidth so things sound clearer.
Some people may not notice a difference, but most will.
It's almost as big a difference to me as going from AM/FM to a CD player.
And it's been in all three Pixel generation phones now.
You can even add it to non-aptX phones if you run a Lineage OS ROM.

Yes, you are correct and I was wrong and was having a 'senior moment'.
.
Well actually I was chasing and focussing on "Qualcomm Aqstic™ audio technology" which is the new one for 845 audio tech . . There was controversy with it and the manufacturer's were calling the 'CVC 6.0 NOISE SUPPRESSION' --> Noise Cancelling, when it is not. It makes the phone calls sound cleaner. True noise cancelling doubles or triples the cost.

DAC in DSP in PX5 units. Spec for Signal to Noise(SNR) and Harmonic Distorsion (THD)

There are some units in aliexpress that include a DSP, but is not really clear for me the enhacement in the quality of the signal becouse of the hardware.
Despite that hardware DSP can be replaced by software viperFX the most possible upgrade can be done with better DACs. That includes people like me that want to send the signal to a better external amp.
For the AndroidAutoShop is unit is clear that they use ADAU1701 DAC: with specification of 104db SNR and -90THD
But this new chinese DSP is not clear wich DAC uses:
https://es.aliexpress.com/store/pro...id-8-0-Octa-core-car/1045641_32865062109.html
I Coudnt recognize any chip there. Even the this NXP is TA8631 where i only could find some references in a russian forum 4pda.
Does anybody have more information about this DSP?
Good: i supose it will be improve the quality of the PX5 standard DAC: 90dBSNR and -65THD
Bad: they need a new branch of MCU firmware. Im afraid it can be a problem of discontinued support
