When using "Sound & shot" mode with the Samsung Galaxy S4 camera, the audio is stored as a WAV file that is embedded into a metadata tag within the JPEG. Here is how to extract the audio using ExifTool on a computer (not android). ExifTool can run on Unix platforms, Macintosh OS X, and Windows. If you are running linux, it might be available through your ...
(At the time of writing,) I've tried researching for 3rd-party apps that can record internal audio only, but surprisingly, I didn't find any. The only app that I found which can do this is SCR Screen Recorder, which just like its name, is actually a screen(+audio) recorder. So, while this app might be an overkill, it's worth to try.
Note: you need root ...
Yes, Android supports standard USB audio class devices:
Android 5.0 (API level 21) and above supports a subset of USB audio
class 1 (UAC1) features:
The Android device must act as host
The audio format must be PCM (interface type I)
The bit depth must be 16-bits, 24-bits, or 32-bits where 24 bits of useful audio data are left-justified ...
Android devices can work in USB host or device mode. Host is the one which controls USB communication. PCs mostly operate in host mode. Device is the one which is being powered and controlled by the host. Flash drive is a common example of USB device. Linux/Android kernel supports device mode through different gadget drivers. UMS, MTP, ADB are different ...
I don't think you can change it by settings. If you see the list of compatible devices listed in the app description, you will find that your device does not figure . Only one plus one from your OEM is compatible
Also if you read app reviews, on other devices which are not compatible, developer says it's due to hardware or firmware incompatibility
It doesn't say it on HTC's website under the specs for the One X, but this review points out that the phone has dual-microphones, used for sound cancellation during phone calls. My guess is perhaps your recording app is recording from the wrong microphone? Or using both to cancel out the pitch you're looking for?
I'd look for settings in your recording apps ...
There is another way to obtain the audio that works perfectly on my Samsung Galaxy S4.
Tell the phone to convert the Sound and Shot files into .mp4 video files, then copy them off using a USB cable.
(optional) Detailed Version
On your phone, go into Gallery and long press on an album to select it. A green tick mark will appear on the top ...
It is inside the JPG and you may extract it with an app, such as SGS4 Audio Extractor by Accalio.
A complementary utility for Samsung Galaxy S4 users
Samsung has introduced the Sound&shot feature which we use at Accalio when taking whiteboard notes.
As we haven't found a software to extract sound files from the JPG files taken by Samsung phone, we've ...
Android's doesn't have an integrated FM radio functionality (API), if a device features FM support, it was added by the manufacturer.
Because of that there's no standard way to access it via 3rd party apps. You can try this app but your mileage may vary.
If you need an external microphone, and your device does not support USB audio (as Hiemanshu's answer suggests): A work-around would be using a microphone with the 3.5" audio jack. As headsets use that successfully, it should work.
I've never tried, so theoretically a side-effect could be sound output gets blocked whith the device assuming you've got a ...
I can't say too much here, but this thing may be achieved by an app called Tasker. Many users say it god of android. To function on every aspect of requirement, it needs root access. In your case, it does not require root access.
You can use its capability to achieve that certainly. This is wiki page of that app.
As OP said that he has hands on ...
Microphone and Audio Input are separate inputs.
I can see the confusion as they both use 3.5mm Jacks, however Audio Lines require a pre-amp prior to the output side, the pre-amp amps up the raw line to give it volume and this outputs digitally formatted data rather than Analog data.
The Microphone on your Android is supposed to be connected directly to a ...
I just found a way to do that. You can use Tasker to automatically start the loudspeaker(which starts using secondary mic.) and then also add a rule to Tasker to reduce the loudspeaker volume to minimum which will very closely simulate the situation.
as far as I know, Google policy don't allow internal audio recording on Android.
But here are some tips:
Some phones have the feature within their UI like MIUI or EMUI or samsung. But you may not hear the sounds while internal audio is recorded.
Also, you can try Elgato game capture card. Many other apps are available (but they frequently need Root though.)...
Not possible without root but even with root SoX recording might not work.
Android Manifest Permissions
Android permission system has different Protection Levels (1, 2); Normal permissions are granted to any app without user interaction while Signature|Privileged (SignatureOrSystem) permissions (whitelisted in /etc/permissions/privapp-permissions-*.xml) ...
The only conceivable way I can think to achieve this would be the use of some kind of external USB DAC (digital-to-analogue converter), which involves routing the audio out through the USB C port
I've successfully done this using a cheap adapter-type "soundcard" (the 'Sabrent Aluminum USB External 3D Stereo Sound Adapter', bought on Amazon), which involved ...
The Cube ACR app is able to do this.
At the top of the menu of this application, turn "Enable recording" on. Then, when calling with whatsapp, you have a button to switch recording on and off. The recordings are then available within the app in AMR format (with the free version of the application), and can be exported, for instance to your google drive.
From the following article, it could be due to need for an impedance (a resistor) between the Mic and the Ground wires. As per
The trick in detecting the external microphone on the smart phone is
to have right impedance between the mic pins. Samsung phones seem to
require a microphone with impedance of around 1.0k – 1.5k Ohm. Some
other devices ...
It is certainly possible, as:
A.There are non root headset button controllers:
B. There are non root sound recorder apps:
So something that combines the functions of both is possible.
Might be a job for tasker, the most famous automation tool. Other automation tools might be capable of the same (think about llama) – but as a Tasker user I'll describe it this way (feel free to adapt).
The "task" to be exececuted would be:
Keyguard › Off
Disable screen lock. Might require the SecureSettings Plugin if the native variant doesn't work.
No. This listener has nothing to do with "listening" in the sound sense: it's listening for intent broadcasts, which are a kind of signal that different software components in the device use to notify each other of important events. For more explanation about broadcasts, see What's the difference between a service and a broadcast receiver?
If you want ...
I found this 3.5mm jack noise-reducing microphone on YouTube: Galaxy Samsung S4 External Mic for mobile phone and here is the mic quoted on eBay. I plan to test it and return some feedback here. I hope it will serve me well enough for the footage I need to create - some homemade lectures.
Try PCMRecorder. From the app description:
This is a simple voice recorder. It records by high quality(PCM/WAVE).
Records in 8000,11025, 16000, 22050, 44100 and 48000Hz - 16bits -
Recordings are stored on the SD-card ('PCMRECORDER').
Records by background
Records no time limit
Playback by backgroud
On my Samsung I9300 Galaxy S III with a Android 4.1.2, I use Camera Zoom FX (non-free): it can take pictures without stopping recordings done by Android's native voice recorder (unlike the native camera application).
The Spirit FM Radio Unlocked has slight support for recording. Most of it is experimental however.
There are no other tuned FM radio apps on the market, that run on all devices.
The only way to get full FM recording facilities, is if your OEM puts this feature into the stock FM radio app.
I have the same issue. After playing around with One X a little bit I'm pretty sure the issue is with the noise cancellation thing, most likely software issue.
There are 2 microphones on the One X - one at the bottom and one at the top. I played a high frequency sound on my earphones and tested 2 cases:
I put both speakers next to the bottom mic. Sound ...
