Well, I don't know a specific application for this specific task. But you can use the built-in camera to record a video (obviously with audio) without unlock the phone.
Most devices have the function to take a picture without unlocking (camera-button, sliding, shaking etc). On the camera screen you can change from picture mode to video record easily.
There is no default sound recorder in Android. Some manufacturers add one to their stock ROMs, but the closest thing on a Nexus device is Google Keep, added in 4.3.
If you assume that a voice recording app is present in all Android phones you'll be caught out.
I use PCM Recorder and it will record until it consumes entire storage space. Also, I am able to use the phone for other tasks and PCM Recorder seems to keep recording in background, which is cool. I can even lock the phone and there by switch off the display which makes the drain on battery to very minimal, in par with the stock voice recorder application.
When I did the "Note to Self", I was sent an email with the attachment (I assume this is the function, I've never used it before!). The attachment is the *.amr file that you can then download, and it will save it to download/RecordedMessage#.amr.
After some searching, the original file is stored in phone memory, not external, at /data/data/com.google....

There isn't any way at this time to force the microphone to stay on for Voice Typing. When you pause for several seconds, voice typing assumes you're taking a break. This likely helps to conserve your device's battery as well
I haven't found any workaround on XDA .
So, I guess sending Google feedback is the only way out for now
I have found a solution to the first problem thanks to the reference by beeshyams.
MortPlayer Music allows you to choose which folders to draw your music from. Hence, in my case, I removed all the .nomedia files from Sound Recorder and only allowed music from my Music folder in MortMusic, thus leaving the SoundRecorder functionality as it was (i.e. ...

I can't say with absolute certainty where they are on a Samsung S6, but on my Samsung Galaxy Note 3, and I doubt that they change their filesystem layout too much from one device to the next.
I can see them from Windows 10 at:

In short, MP3 is a Compressed audio file format, which means some details of Audio will be deleted to reduce the size. If you record your audio in MP3, the quality will be low than recording in Other formats such as ogg or aac.
Hardware is not a limitation. Recorded audio can be converted into any other format using simple software.
Note: Now-a-days many ...
After trying the voice recording I've found that the recording stops whenever there is silence for a few seconds. In other words, to make a long recording you'll need to talk continously.
I've so far found no way to increase the length of this silence period in order to stop the recorder from prematurely stop recording. Please comment if you know how to do ...
Like @Izzy mentioned in the comments, Tasker is the way to go.
Here you can see a List of Plug-Ins and 3rd Party Tools where you can find Easy Voice Recorder. With this installed it will be easy to create a Task for recording ;)
Try Easy Voice Recorder. It works for me (Nexus 4, Android 4.4.2 without root).
When you have root privileged, it is much easier. But without root, I don't know any apps that can record the other side in a way that you can hear him "clean". But as I said, Easy Voice Recorder did a very good job for me. Not perfect (crystal clear), but good (I can here the ...
You can configure Note Everything to do regular backups of all your notes (they will be stored on SD card then). If you additionally want to have those data sync'd with "the cloud", you might want to take a look at specific synchronization apps, like e.g. FolderSync. This way you can keep the app you are already used to (and which is wonderful, by the way -- ...
