We now know the G2X has only one media speaker, and I was a bit bothered watching videos and the sound comes from only one side. Maybe I am just expecting too much from a phone, but I was wondering if it was possible to make use of the speaker (the one you use for regular phone calls) to create a stereo effect to a listener directly in front of the phone.
I am aware this speaker can't output as high a volume as the media speaker on the bottom of the phone. Is it possible to have this speaker output at a volume such that the media speaker match it in a relatively similar volume so that the listener directly in front of the screen can hear stereo sound? That is if it is even possible to route the sound to output from both speakers at the same time.
If possible, maybe someone with the experiences can add this feature into a custom firmware?
Hey there.
Since i bought my o3d, i noticed there is a small hole next to the power button so I searched and found out that it's a mic and its only used for stereo sound recording. I was wondering if there's a tweak out there which will make use of it as an active noise cancellation mic instead as this would be far more useful.
Thanks

Actually that mic is for noise cancellation ,am not sure whether its using for stereo recording .But its mail purpose is noise cancellation . Now a days many smart phone have two mics.
Is any idea for enabling stereo sound recording from two sources (main mic & sub mic) at once?
LGCamera can enable but only one at once; sub mic (camcorder) or main mic (microphone) never both
This would be very COOL!
Hi, when I play any form of loud audio through my Samsung Galaxy Note speaker, it cuts out. This includes incoming ringtones, loud music through music player or loud youtube videos. If I lower my device volume down to about half it works fine but any higher, it cuts the speaker out!
I have flashed 2 different roms but both have the same issue. Is it a hardware issue or a software issue that can be fixed?
Thanks
Hi,
Z3 Stock screen recording app always uses the MIC for audio souce. So it records my voice instead of the voice I hear in speaker (or headphoes). But I want to record the sound playing in the phone.
Any suggestions?
Can any of the early adopters here confirm whether the Pixel (not XL) is capable of recording stereo audio when capturing videos? All of the example videos I've seen on YouTube seem to be recorded with monaural audio.
This could be the only deal breaker for me. I take my HTC M8 to concerts frequently, and it captures phenomenal stereo audio that doesn't distort or clip in loud venues. As much as I like the Pixel, I would probably have to buy the HTC 10 instead if the audio recording capabilities were overlooked by Google.

I just did some testing for you. The built in video recorder records in mono. However, the Pixel obviously has the ability to record in stereo because I just tried the "Sony Audio recorder" on Google Play and it records stereo audio. If you just need audio and not video this has the ability to record very high quality stereo recordings.

Wow thanks for looking into this!
I'm really disappointed to learn that the "best phone camera ever" doesn't record videos in stereo! Google really needs to address this in an app update quickly.
Good to know that the hardware is capable, at least. The Pixel also seems to do well in very high sound pressure levels too, based on concert clips I've seen posted on Youtube (this is something HTC has always excelled at).

Okay.... It is not very meaningful as "stereo" it is not an XY or A-B studio recording physical pattern.
It is more useful for most people as a mono recording, less noise that is heavy left or right from handling phone to record a "home video" (of a meowing cat or cute baby etc)
That said I am an audio engineer and musician, and I can see a usefulness in having two sources, in case one is better. Mixing them might be better with some of each side panned to the other.
I just consider it two channel recording. Stereo is about perceiving a binaural field L+R, not just two paired signals. The analogy isn't moot. A single mic close to a sound source in a studio and one mic in a distant point that provides "room noise" or "reverb" is 2 channels, not a stereo.
So I think it better to know that there are many options and considerations to make when you do use an app to record with both mics as to how to mix the sources knowing they aren't intrinsically just stereo. That's why I prefer the built in camera app to just stick to mono which is overall better sound for most people. 2 channels only sound good if you do some "audio mixing" in a DAW....

In your tests, did you compare the waveform of both channels to see if differences exist? How do you know the Sony app didn't just take the mono input and record it to both left and right channels?
Hi I didn't compare the waveforms I just listened to the audio. If you record a single sound source and rotate the phone while recording you can hear the sound going from one ear to the other on playback. If it was a mono recording you wouldn't be able to tell that the phone was being rotated at the time the recording was made.
So which mic is left, and which one is right?

You can easily tell immediately if a video was recorded with 1 or 2 channels of audio, especially when wearing headphones. Here is a clip I recorded with my HTC M8... Notice how the sound pans when I turn the camera away from the stage!

2 channels is simply more lifelike... We have two ears, so the Pixel should be using two mics for the most realistic audio.
Device: Pixel (sailfish) running Android 7.1 Nougat
One of our users (we are developers of an audio recorder app on Google Play) is reporting that the top microphone on the Pixel has a slight hiss (when he records stereo audio).
Is this an exception (maybe just a bad device) ? Or are other Pixel users seeing this as a general behavior on Pixels ?
This is confirmed when he records mono audio as well, by using the top microphone (aka "Camcorder" microphone). In our app, the user can choose the "Audio Source for Mono" and set it to Camcorder for the top microphone. For stereo, the user can modify the "Audio Source for Stereo" to find a setting that works best. Even the best setting there had a hiss when recording audio. Hiss was less obvious in certain environments.
Hiss in the top microphone on Android phones can be due to interference from the antenna. One can test if this is the cause, by turning on the Airplane Mode (which shuts off the antenna). Usually the hiss will disappear.
However, in his case the top microphone persisted in having that slight hiss (even with Airplane Mode set to On).
Thanks.
EDIT:
To test this with our app, you can search "mp3 recorder" on Google Play - our app is the "Amazing MP3 Recorder Pro" app there.
EDIT 2:
I have heard back from one person who is suggesting the problem is NOT universal to Pixel - and may just be a problem with that user's device (thus warranting a RMA - Return Merchandise authorization i.e. a return candidate).
