Recording Internal Audio - General Questions and Answers

I've been searching for the past 2 months on a reliable way to record the internal audio and so far I've come up completely short.
Is there no way at all to just record the audio output of my phone without have to do a screen record?
I have the Note 4 w/ Lollipop installed and the SCR Screen Recorder app simply doesn't record internal audio at all. I have an older Galaxy S3 that does record internal audio but the act of recording the screen as well as audio at the same time while playing an audiobook leaves the app choking at random points and time.
I'm frustrated that there's no solid way for me to record the output of my phone cleanly without going through all sorts of shenanigans.

Try Mobizen for Samsung. It has a feature to record internal sound, also it's safer, since it doesn't require root.

[Q] Phone won't play back music or video audio, notification rings work

Hey all,
My girlfriend dropped her LG Nitro HD in the toilet this morning. We immediately did the whole rice thing for a couple hours and now her phone's in mostly working order, save for a small audio issue. When playing music or video, the audio won't play back out of the speakers, even with volume maxed. No sound at all (though the audio does work with headphones plugged). However, all incoming calls, SMS, etc. will have the appropriate audio playback working just fine out of the speakers.
I'm thinking there was damage to some part of the phone which is causing this error, but I don't see what. I can't imagine why we'd get audio from notifications but not music or video. Is there something I can do to try and fix this?
Thanks!

Hello, when i record any voice with smart voice recorder, the volume of recorded voice is very very low. I have used it to record my class lectures. But now i'm unable to listen as the volume of the clips is too low..
Any solution?

I found my Moto G to have a similar problem with the stock app, recorded audio was almost impossible to understand due (in large part) to very high compression rates. Using a different app that allows you control over the quality of the audio helps, though the microphones on any phone are meant to pick up audio from much closer up than most other microphones. I really like Smart Voice Recorder, it's easy to use and has some great features. [https://play.google.com/store/apps/details?id=com.andrwq.recorder]

1) Moto g doesnt have a stock app for voice recording
2) I clearly mentioned that I had the problem with smart voice recorder. And you are suggesting me that same app.
3) I'm not sure which phone you are using and I dont think you even read my question

Stereo Audio Recording?

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).

Audio distortion/clipping in loud environments

Hey Guys!
I have a problem lately on my Galaxy S6.
When i record videos in loud environments the audio gets really distorted and the video gets unusable.
Its really annoying since i like to record videos when i go to concerts etc.
Never had a problem with it until a few weeks ago.
Does it have something to do with nougat?
Here are some examples:
youtu.be/wb_8UHzyEO4
youtu.be/Dh4ZNHt-hsc
Do you know what causes this and is there any fix?
Maybe theres an audio mod which includes auto gain control or a limiter or something?
Thanks in advance!

how to record Audio without EQ/Compression while shooting Video

hi all,
I need your help because I want better Audio Quality while recording Video. Is it possible to get the direct output from the internal microphone without loudness compression, noise supression and EQ to edit it by myself afterwards?
Had a mod like that installed on my Nexus 5 some years ago, maybe it is also avaliable for the Oneplus 6.
thank you
