Download !!BETTER!! Microphone Recorder

Easy! Yes! Just select one of the options with the screen and webcam - you will appear on video in the corner of the screen, while your desktop image is recorded, and audio is captured by the microphone. Pretty handy, right?
The high-capacity Li-polymer battery can be easily charged through a standard micro USB jack. This guarantees extended battery life for extra-long recording up to 50 hours, ensuring that your recorder will always be ready to work when you are.
my obsidian used to be able to record both computer sounds (audio i play) and my microphone, now both does not work and i cant hear anything from the recording. I dont seem to find any place to specify microphones/audio device either, did anyone came across the same problem? Thanks
i dont think this is an unnecessary feature, so should be native, stuffs which people need just for their workflow or which is not really necessary for the OS as a whole and will make it overkill and would judt increase bugs can be covered by plugins, but i dont think voice recorder is a supplementry feature to have, i import audio files a lot, sometimes in my study notes, sometimws in general, so its a wide use case for me and i can see it for many ppl too, native would be good!
I have an Olympus EM5-Mark III which I now quite frequently use to produce small videos of my son where he is 1 to 5 m away from the camera. I'm happy with the video quality, but the sound of the built-in microphone is nothing to rave about.
A while ago I bought a cheap Pixel MC-650 microphone and while the sound quality is surprisingly good, in about 1/3 of my videos I have a low frequency " wind-like" noise, no matter if I'm outside or not. This noise is also there when I use the microphone on my Nikon DSLR, so that any issue on my E-M5 can be ruled out. I haven't been able to trace back the origin of this noise. I have played with different options (preamp on the microphone set to 0, +10, -10, low pass filter on / off, different options inside the camera). I have also excluded any possible noise pollution from pressing buttons, AF or IBIS motors. My conclusion is that the thing is defective.
When the microphone is far from the subject, the automatic gain in the camera's audio circuit will boost the volume until it's at an acceptable level. The problem is that it can't distinguish what you want and what's just ambient noise or wind. They all get boosted the same amount.
Nothing beats getting the microphone as close to the subject as possible. That gives you the best signal-to-noise ratio between what you want to record and what you don't want. In other words, the subject is loud enough that the recorder doesn't have to boost the volume of all the junk you don't want.
You can do this by recording with the camera using a wired mic and a long cord, or a wireless mic. Or you can do it using a portable audio recorder, either using its built-in mic or using a wired mic plugged into the recorder.
Thank you all for your great advice. In the end, I believe that I expected too much from a shotgun microphone. After all you cannot beat the laws of physics: the closer to the source you are the better the SNR. This is never mentioned in all those fancy YouTube reviews... Maybe because it is too obvious.
Given that your "talent" is only 18 months old, his utterances will consist mainly of babble for another year or so. An external recorder should suffice, and there will be no particular urgency to synchronize the audio and video precisely.
I have an Oly LS-P4. The sensitivity using the built-in mics is at least as good as a Rode VideoMicro. Given that the VideoMicro is the cheapest of the Rode mics, I guess a decent mic might do better. The advantage of a separate recorder is that you might be able to place it nearer where your son is playing.
Back up and sync automatically saves your recordings to your Google Account at recorder.google.com. If you log into your account, you can get your recordings from any device. You can choose to back up and sync some recordings and also choose for other recordings to stay private on your device. .
I can see that it has the options of selecting channels. I am a newbie in this area.
What do those channels represent? Do they represent different microphones? Selecting many channels means that we can use more than one microphone for recording?
To submit translations, you will first need a Crowdin account. You can sign up for one here. After creating an account you can submit your translations for the voice recorder component by doing the following:
Plus this component is more or less just a demo than a production tool. You (and yours users) should do audio more basic way: use your devices (mobile, audio recorder, deskop, what ever) and upload that file normally.
A good start would be adding in any case 'start if sound', so that a new file should be created when sound starts; but in order to have a new file, first the recorder must be made to stop when there is no sound. 'stop if silence' is not a good option, as it creates a lot of small useless files; a better option is 'stop if silence 1 sec.'. 'stop if silence 0.5 sec' may also be a good option. (This should be enough for the stated purpose. Using audio threshold timer commands seems to me more complicated.)
I'd imagine when the original audio widget was built there was more of an assumption Android would, at some stage, adopt a stock audio recorder (like on iOS) but this has never happened and even worse, the ecosystem around audio recorders on Android has never stabilized. How long before Google kill that recorder app?
@Inti_Luna if you're interested in funding development of an audio recorder for Collect (with the key points you've outlined) I think talking to @yanokwa here is your best course of action. I'd love to see this happen and I think there are also some cool options around building in-app recording that can also be distributed as a standalone app but we can hopefully we can talk more about that soon!
Why only these formats?
I've been involved on qualitative studies where we need to record an interview up to 1 Hour and we struggled with mp3 or wav. The dimension of the final file was huge and it was impossible to manage then to upload the file on the server.
We found an apk that produce amr file that translate to a file less then 5MB.
If collect would have an inline recorder should allow to choose the compression size in a way to deal with long recording.
What do you think @seadowg and @yanokwa ?
Historically, recording was done through an external app to limit the already large scope of Collect and to let users with external microphones and other specialized needs pick an appropriate tool. It does seem like this has been inconvenient for the common case.
Doing a little bit more digging, Axet audio recorder seems to be the most widely-used open source Android recorder app. It has many different encoding options and lots of nice features like audio trimming. It's GPLv3 (source code) and actively maintained. We have updated the documentation to refer to it.
I will still benchmark the different options, including the Axet audio recorder LN mentioned and the Opus format mentioned in the thread created by Tino. The main criteria I would focus on at this stage would be the usability (recording with a given compressed format should be as straightforward as possible for the data collector, with as less manipulation as possible), the size of the audio file (for both transfer and storage) and the quality of the audio for transcription, possibly testing in different contexts (we have a walking interview, so possibly a more challenging recording environment).
The Samsung Voice Recorder app is designed to provide simple and effective recordings with a high quality sound. Use the recorder to save voice memos, interviews and convert up to 10 minutes of speech to text, helping to make your life easier.
Hi,
I think an audio recorder or plugin feature would be great and would be another great feature for logseq, since it is a wonderfull studying and working tool. I am studying law in Germany and I use logseq as my main studying tool alongside anki, which integrates very nicely.
But I also use notability for classes, since it features a great audio recording feature. I also stumbled over an app called noted, which is also great for notetaking and audio recording.
I think an integration of one of these apps or an inapp feature for recording with timestamps and dictation would really be another step towards a great and fersatile study app. I think lots of people nowadays work with audio recordings, that can be searched easily.
It would add another layer (hearing) besides typing, whiteboard with its drawing feature.
Thanks
So my vote would be for an audio recorder feature where every block generates a timestamp in the recording when it is created so that you can click a playback button in the block and playback what was being said at the time you made the note.
There are two types of flight recording devices: the flight data recorder (FDR) preserves the recent history of the flight through the recording of dozens of parameters collected several times per second; the cockpit voice recorder (CVR) preserves the recent history of the sounds in the cockpit, including the conversation of the pilots. The two devices may be combined into a single unit. Together, the FDR and CVR objectively document the aircraft's flight history, which may assist in any later investigation.
The two flight recorders are required by international regulation, overseen by the International Civil Aviation Organization, to be capable of surviving the conditions likely to be encountered in a severe aircraft accident. For this reason, they are typically specified to withstand an impact of 3400 g and temperatures of over 1,000 C (1,830 F), as required by EUROCAE ED-112. They have been a mandatory requirement in commercial aircraft in the United States since 1967. After the unexplained disappearance of Malaysia Airlines Flight 370 in 2014, commentators have called for live streaming of data to the ground, as well as extending the battery life of the underwater locator beacons.
