[Q] Stereo Recording Video with Camera FV-5 - One (M7) Q&A, Help & Troubleshooting

So I read about this work around but I can't help but think there must be a way to implement this(From android forums) http://androidforums.com/threads/stereo-recording-support.786561/:
Yes it is possible with this workaround:
Start recording with an app, which supports 2 channel audio recording.
Then switch to the phone application and dial a number. After you pressed the green phone button, just press it again to cancel the call.
This procedure enables the camcorder mic for the phone noise canceling function. And HTC forgot to close it after a call, because another application still uses the audio engine
So return to your recording app via the double-click for the task manager and you will have 2 independent channel audio recording with left and right signal.
I found out this in August 2013 and reported this trick to 2 developers of audio recording apps, but they were not able to find out which command HTC uses to enable the camcorder mic. HTC did not answer a request to publish the method.
It is necessary to repeat this every time. If you pause the recording the camcorder channel will be closed and the device changes back to the mono recording via the main mic.
So I hope some developers of custom firmware could find a solution to enable the camcorder command via software command like enabling Bluetooth mic.

What I did was start the call, swap to the camcorder, hit record and end the call in the taskbar... and surprisingly enough it does work as weird as it is. The problem is a, you have to make a phone call to make it work and b, when you stop the recording, it goes back to mono.
I'm guessing if a developer was feeling froggy, couldn't this be done if we knew what was being called?

Does any call recording software works on the Kaiser ?

Hi,
Can you please test and see if the phone is hardware limited to record the voice of the other person on a call like many other HTC PPC phones.
Software like:
VITO AudioNotes v1.3
Resco Audio Recorder 4 betas
LivePvr
PM Recorder
or even with the build-in Windows Notes.

but does it record the call partner voice too?
I know it was possible to record the whole conversation only on smarphone because of an hardware limitation in pocket pc instead smartphone.
Thats also very important for my decision whether to buy the Kaiser or not!
Anybody - please check and post... (would be perfect if somebody could make and record a short test call and attach it here )
Thanks a lot!

yes, vito audio notes records the other person's voice too. you can just record whenever, or have it automaticly record when u make or recieve a call. it has different settings of sound quality too.

I know they say that it works, but actually it doesn't for all newer HTC Pocket PCs - that's why we are asking. Anybody here who really tried it and can attach a test call (without loudspeakers turned on!)?

well, you can see if you do some research - it's a hardware limitation as the phone audio system is not fully integrated into the Windows Mobile audio system...
This is also a feature i would like to see!
There is talk about utilising the Bluetooth Stack to record the call (both ends) but i dont know how far along it is.
Its really frustrating that the PPC phone edition isnt smarter than the 'Smartphones' that can record both ends!
Perhaps we should actually look at this a little differently.
The PPC recorders all seem to record via the mic, but how about a recorder that can record only the audio sent to the speaker! (Thus recording the other person!)

The PPC recorders record via the mic because recording the audio sent to the speaker doesnt work, that is the limitation everybody is talking about. This audio routing is handled in hardware itself and software is not able to tap it in between...

Hi Shantzg001,
I realise they dont record both, but i am suggesting that it would be great to find something that can only record the speaker, not the mic. Just as if you wanted to record streaming music. (that doesnt record from the mic).
I havent found anything yet that can do this but it could just be the search terms im using.
I can confirm that unless you use the speakerphone that Vito Audio Notes, as was supsected, records only the microphone (your own voice, not the other party of the call)of the phone conversation. Also the "auto record" for phone calls does not work when activated either.
Try Resco Audio Recorder, it has trial version for sure.
Some people said it works.
I tried it - you don't hear the other side of the call on the recording unless you use the speaker.
Damn
I really missed this feature (phone recording).
I hope there is a registry setting "EnablePhoneRecording" or something like that.
Do you think this is hardware limitation? Or application issue? or OS? ... hard to guess.

Good Conversation Recorder for HTC Phones??

Hi
Have been using Resco Audio recorder and Vito Audio Notes to record phone conversation but in both the softwares i could only here my voice clearly and the other persons voice is not audible at all. I have faced this problem on ALL HTC DEVICES but the same software worked amazing on XDA Xing and ATOM. cam someone help me here as to what settings to change or what software to use for proper recording.
Thanks
all of these programs will record if the phone is on speaker.
read the documentations, as some phone do not provide duplex conversations, or something like that.
once you set the call on speaker, all works fine, but it's kind of inconvenient.
yea if i remember correctly, it has something to do with the way that the voice calling was implemented in the device that it will only record your voice.
straight from resco.net from the audio recorder page:
(Both sides recording is hardware dependent. If your recording contains voice of one side only, it is not due to the program's failure.)
On my old PPC6700 mine worked fine with the call volume all the way high, The other person sounded a bit low, but if you want you can edit the call on a PC and make them louder. It all depends how often do you plan to record your convos.
I'm recording both sides without speaker or any other hazzle...
This is what I've done:

Do you really intend to unbury every 1+ year old topic on that subject? I think people got it by now. Make ONE thread with full relevant info, that will do it.

Need a Call Recorder for windows mobile

I have the Sony x1.
I always find myself wishing I had recorded calls.
Is there a way to have your phone automatically record all calls.
If it was just a stand alone program that needed to be activated each time I think would forget.
Try this:
http://www.freewarepocketpc.net/ppc-download-acr-auto-call-recorder.html
Same as above:
http://forum.xda-developers.com/showthread.php?t=536472
It only works one way though...
The X1 has call recording built-in through the Notes app (also accesible through the phone dialer. Once in the Notes app, go to Menu->Use Recording Toolbar. You can record the conversation while writing into the notes app. It's unfortunate SE didn't integrate this better into the dialer app.
You can record both sides of the conversation if you use speakerphone only. Using the handset, it will only record yourself and the other end will be inaudible. I believe this is some hard limitation in the design of the phone and not something that can be overcome by software.
EDIT: Ooops, I see you want calls recorded automatically...Notes doesn't do that
How do I access the feature through the phone dialer.
If you are using the built-in SE dialer, it is the icon that looks like a sticky note with a tack through it. Pressing that will load the Notes app with the number you are dialing already inserted. From there, just follow the instructions in my previous post.
I believe once a call is initiated, you can still run notes the traditional way (Start Menu->Notes) and achieve the same thing if you have a different dialer you are using.
This functionality with notes is cute, but it only record some 30 seconds. How can I change it. Through regedit or?
One more thing: The loudness of person that I called on recording is miserable... My voice is lot louder... how can I fix this?

As stated in my first post, you have to use speakerphone to get a usable record volume from the other caller. This is inherent in the X1 design.
I don't understand why some phones have this limitation and others don't. My old Moto v60 could record both ends of the phone call perfectly without any fuss.

Look at Resco Audio Recorder.
I have tried many programs and none work perfectly so here is what i did to get perfect results:
Plug your xperia into the "Line in" port on your computer using a male to male 3.5 mm audio cable - after that i used a program like Audacity to record the call.
It records your voice and the person you are speaking to with perfect results.
^^^ That's clever, but how do you fit your computer in your pocket?

[Q] Camcorderproblem: Only one channel recording instead of stereo after 4.4.2 update

After I updated my HTC One to Android KitKat the Phone only records with one channel (left channel) instead of two (stereo) when using the camcorderfunction.
Anyone having the same issue?
What Rom are you on? I wrote about that when I installed Viper over the weekend. Noticed exact same thing. Thought my second Mic was dead. The only one active is the Mic on the bottom.
But, I returned to my 4.4 stock kit Kat T-Mobile US Rom, and stereo recording is working.
If you can list what Rom you are on that would be great.

Not sure...we need more testers to try some video recording and post results.
The problem is that testing a video and relying on the phone speakers to show the problem won't work, since the phone speakers will play the left track through both speakers, giving the appearance that audio was recorded in stereo...
The video needs to be listened through earphones, or copy the video from the phone to PC/MAC and then give it a listen.

I've seen a few posts in the Rom threads where people have brought this up. Saw a post in Revolution and Insert Coin threads.
But we need more people to test video recording and then listen through ear buds or on computer.
Anyone who is on the latest and greatest Sense 5.5 kit Kat builds, can you please make a short video using the Sense camera app, and listen to it through headphones or on computer? Do you only have audio coming out of the left channel?

Yes. But strangely, when I restart the phone and make a video, then it works perfectly :S But when I make a second video, the audio comes only from the left channel.
I can confirm that.
There is a command, which HTC uses to activate the camcorder mic. Maybe HTC forgot to call this procedure when restarting the 2nd recording.
The function is already present in the phone application to enable the camcorder mic for the noise canceling function.
I use this as a workarround to enable stereo recording.
Maybe someone can compare the old and the new video app to find the "enableCamcorderMic" Function and make it available for other applications. There are some applications which allow to select between the main and the camcorder mic. They work on most devices, which have 2 mics, but not on the HTC ONE. This can be tricked out by switching to the phone application while a recording-application already records. Start a call and cancel the call. Then return to the recording app via taskmanager and you will have 2 channel recording. Unfortunately this does not work for the video app, which cancels video recording when switching to the phone app. But I did not need the workarround in the past for the videoapplicatiom. But now HTC has a bug in it. I hope someone could be able to isolate the "enableCamcorderMic" function.

Hi - can you explain in more detail what your workaround is? Take first video - then open phone app - then go back to camera app? Or does this not work anymore.
Anyone else experience this issue of only getting stereo recording in the first go around...exit camera app....go back to camera app start a new video.
listen to the second video you took through headphones or on computer - do you hear both channels?

I described it more detailed here But unfortunately it does not help for the new camera bug, because the video application stops recording, when switching to the phone application. Normal audio application continue recording when taking or receiving a call, so they benefit from the oping of the camcorder channel which the phone application does for the noise canceling funciton.
Did you try to install the old video application from older stock ROM to your phone. Maybe that helps.

I actually threw on one of the Sense 6 roms. Guess what, no good. Same exact problem.
Something tells me its in the kernel of 4.4.2.
What's bugging me is that no one else either doesn't notice this problem or doesn't care judging by the lack of of comments I've seen. It would be hard to get a Dev on board to look into if there is lack of interest.
Right now I've flashed a Google play rom. While the Google play Roms don't do video recording in stereo at least mono recording is handled correctly, by distributing the source to both channels.
In sense its not mono in that the right side is just dead. Nothing worse than playing back videos on a computer or TV and having the right speaker sometimes on and then off.

Yes your observation is totally correct. The camcorder mic is responsible for one channel. If it is not available you will get just one channel. In my testings the phone switched to mono recording from the main mic.
I tested to reinstall an older HTC video app via titanium backup, but it did not start.

I can confirm this. I just did an RUU and i recorded using the voice recorder and video recorder and both come out with only 1 channel being used and its the left one.
https://www.dropbox.com/sh/xuxe5l1xvqutp0g/JSajfATqqY That has 4 samples in it, 2 using the latest stock update on the sprint htc one m7 and the other 2 are from the sixth sense rom rls2
I am running 4.19.1540.1
EDIT
Ok I see what you're talking about.
Steps to reproduce:
1 Boot to a kit kat sense rom
2 record video A
3 immediately record video B of exact same ambient soundfield. Repeat if desired for videos B1, B2 etc.
4 reboot
5 record video C of exact same ambient soundfield.
Videos A and C are in stereo, video B is in mono.

VoiceRecorder was never able to record in stereo, or select the camcorder mic. It stopps, if you change to other app via task manager. So you can not use my workarround to enable the camcorder mic.

Yes, and following videos D,E, F... Only the first video is in stereo.
So the enableCamcorderMic function ist used in the new video app after reboot. I experimented with killing camera app, gallery and videoplayer after the first video and sometimes I got back the stereo without an reboot. For this I used the app "TaskManager" (not simply the function in the "recent apps" screen). But i could not find a reproducible way.
So we need a firmware switch for this function. Then all apps would profitate from it:
Selecting main or camcorder mic for mono recording.
Using stereo recording.
Using mono recording from both mics. This helps if you held the phone while making notes of a speech (e.g. in university) and recording. On the HTC ONE the main mic points to your body and not in the direction of the speaker.
I hope that one of the devs could find out how HTC enables the camcorder mic in the video app and in the phone application when pressing the call button.

I had asked Kernel Dev Flar2 to see if he could reproduce the problem and he could on his M7. He said he might take a look if he has time, but I think he's got the M8 now, so not 100% sure. Hope that he can.
In the meantime - to counter the issue, I've flashed now a Sense 5.5 Android 4.3 Rom on my phone, running on top of KitKat firmware. Stereo recording acts normal the way its supposed to everytime exiting and reopening camera app. So if you need stereo recording, until someone fixes it, I suggest finding a Sense 5.5 Jellybean Rom.
For me its important because I'm always capturing videos of my 6 year old and can't tell her, 'honey hold on, I need to reboot my phone so I can record you in stereo"....
Somehow we have to grab the attention of HTC so they are aware, I hope they don't leave us hanging now that the M8 is out and attention is focused on that.
It would seem to me that everyone who is on a KitKat firmware/Rom probably has this issue - we just need more testers to confirm and then go to HTC on Twitter/Facebook.
gustav30;51474822
Somehow we have to grab the attention of HTC so they are aware said:
Well I have reported the missingaudio recording for normal apps months ago. Even to HTC. I have also uploaded them a audiofile to demonstrate the workarroud, but they told be that they will send it to HTC developer team. I am waiting for months so I decided to share the workaround although it is complicated. I think they don't want other developers use both mics for stereo recording. The people should use the own HTC video app to capture stereo videos. But now they have fallen in their own hole by forgetting to insert the enableCamcorder function in the new videoapp for KitKat. It is ouside the normal Android SDK, so normal developers are not able to use the function.
This is really a restriction and a challenge for developers.
And I think HTC has to react and update their video, because many people will complain the missing stereo on video.
The professional musicians are in small minority, but if you once heard the difference between mono and stereo you will always prefer stereo, because you can better understand even an recorded speech in stereo.
