Virtually all modern audio interfaces for computer use have clock-synchronized sampling across all inputs. This is a prime requirement for most ordinary multi-track recording. It would be difficult to find a modern, multi-track (>2) audio interface that did NOT meet this requirement.

Here is 4 channels for $250 with mic pre amps and dedicated outputs should you need them. There are a handful of 2 channel units for under 200 here is a 4 channel right at the $200 mark. You are brushing right up on the lowest quality level at that price. You may sacrifice quite a bit of quality which may impair what ever research you are doing.
Side note: ...

The recorder supports 3 different recording modes:
Stereo: either the build-in mics OR external inputs)
4CH: a stereo file for the build in mics AND another stereo file for the external inputs)
MTR: Custom mono/stereo setup for all 4 channels.
MTR Mode is probably the one you want to go for. In MTR mode, you can send any input to any track. For example ...

Before you get too far in - make sure you are aware of the latency issues common with most android devices. This might not matter for your application but it could be a dealbreaker if you are planning on doing overdubbing etc.
The first issue you will come up against with using multiple sound sources is that their clocks diverge. Even though each one is ...

In short, no. Your DAW will have the ability to route signals to and from the interface as is. Each channel strip in the DAW can have sends and receives, same for the monitor channel. For example if your DAW has a monitor channel that automatically receives solos, you route that monitor channel to a hardware output on the USB interface. The exact way of ...

I do this all the time. Position the playhead at a convenient/natural point between songs, select all the regions, and "Split Region(s)". At this point you will have a "song" and "the rest of the audio". Place a marker on the first set of regions. Make the song work. When you are satisfied create a new "Alternative" and move to the next song (position ...

If it is all one band doing one contiguous concert, I wouldn’t want to break that up into 16 projects, because you will likely want to treat each channel in basically the same way. It likely really is just one drum recording, one guitar recording, and so on, even though it is many songs. If you split it up, the things you do to the drum track, you might have ...

Basically, a 'channel' is an audio signal and a 'track' is where they can be written/read.
In recording studios, before the digital revolution, multitrack tape was used to record single channels of audio onto separate tracks.
Multitrack recording software now has the capability of creating an unlimited number of tracks, and for each track, you can have ...

This is a common misconception about tapes and tape recording.
Tape is a magnetic medium and it's not divided by anything.It's particles are (at first) scattered and unordered.
What dictates the channel count is the recorder tape head.
This is a basic example of how the tape recorder works:
So for example let's say we have a 2 inch tape.
And let's also ...

PlayStation Eye is one of the best and cheap recommendations. It is a microphone array with 4 microphones in row with only 35 dollars.

You can achieve that with this or this
I've used both with great success when streaming to twitch and hosting remote lessons to my students

This is called crosstalk: the signal on the left channel leaks into the right channel. When you have 2 audio circuits (left and right) close together without being shielded, the electromagnetic fields produced by the circuits influence each other.
This can happen anywhere in the analog signal path: in the sound card of your computer, or in the headphones ...

I think so, yes. Route both L and R to one matrix bus, and assign that to Out 1.
That depends on how you provide a signal to the Out port: Out 1-16 is just the output assignment. You set the volume on the channel that feeds the output. This can be the mains, but also any of the buses, an Aux bus or a matrix.
You're comparing apples and oranges:

If the audio inputs are correctly configured, you can use the method in this answer (or any answer to that question).
The only difference would then be multiple instances of VLC.
(Sorry for the short answer, but I can't currently test the method. Hopefully it'll be the direction you're looking for.)

One setup that I've found to work pretty well is an all-in-one field recorder, such as a Zoom H6 or a Tascam Digital Portastudio. Such devices can often be found for cheaper than the cost of a full recording setup and is an all-in-one device that handles everything for you. Plus, they keep their resale value pretty well so after you're done with the project ...

Have you actually TRIED recording with a phone in your conference room? If you identify exactly where is the microphone and hold it around 8 inches from the subject's mouth you may be surprised how well it works, assuming your room is not very reverberant. DO NOT assume you have to go out and buy extra gear (especially for a one-time temporary application) ...

Depending on what features you require and the gear you have, the Zoom R16 might work. 8 inputs with preamps, records to an SD-card, 16-channel playback and runs on batteries if needed.
I don't know anything about the quality of the R16 compared to the F8, but it is a lot cheaper for the same number of inputs.

I think you're asking too much here. The Zoom F8 is probably one of the cheapest 8 ch. portable solution available.
EDIT: Tascam made a "portastudio" too - the Tascam DP24 SD. It has 12 mono tracks and 6 stereo tracks, simultaneous recording of 8 tracks, simultaneous playback of 24 tracks and records on SD-Card.
If you reduce the number of channels you'll ...

Focusrite do a wonderful range of low cost adda and preamp hardwear (scarlet range) that will serve your purposes very well

Of course there are, any mixer that comes with an audio interface is what you are looking for.
For example :http://www.hifisoundconnection.com/Behringer-X32-DIGITAL-MIXER-32-Channel-16-Bus-Total-Recall-Digital-Mixing-Console-for-Live-Recording-Applications-X32
But they can be pricey !
You might be better off having an analog mixer and a separate audio ...

I'd look for any encoder that can support MPEG-TS encoding for 30 channels. The problem you will run in to with doing 30 independent ffmpeg streams is that they will not properly interleave and you will likely get jumps when switching channels.
You need an encoder that can take in to mind all 30 streams and use a fixed clock to sync the packets of audio ...

According to the manual:
The INDIVIDUAL channels sent to the computer send the signal after the
preamp gain knob, the high-pass filter, the three-band EQ, and the
channel fader.
The effects of the AUX send knobs are NOT included in the outputs of
the individual channels.
The MAIN mix channels sent to the computer exactly mirror the MAIN

When recording, each "timbre," in the sense that you're using of, instrument or voice, is generally recorded to a separate track so adjustments can be made to each individually in a software that looks a lot like audacity...
HOWEVER
Once adjusted and prior to the music being released, all the individual tracks must be "mixed down" into usually a stereo ...

I think the quote is misleading. Let's say you want five different MIDI violin parts to play, all with the same violin sound. You would normally have five different MIDI tracks, each with their own mixer channel to process both MIDI and audio data (so five channels - sometimes called instrument channels or instrument tracks), and all the five channels would ...

What you are interested in here, is the side material, or the difference between left and right (i.e. when these don't play the same).
Typically vocals are mixed equally loud in left and right channel (the vocal is in "center"), but the accompaniment is spread out differenty across left and right side (or channel).
To get that difference you need to get ...

I recommend paying attention to various MADI solutions.
For example, I highly recommend to see the RME's MADI solutions in conjunction with an Ferrofish's A32 AD/DA Converter
You can add and add new MADI expansion in the chain - up to 32x/64x/and more analog ports.

You could get a very solid 30 output system from RME using their MADI DA:

Not cheap though!

Many professional external audio interfaces can be stacked or extended to get more inputs/outputs: RME, MOTU, Avid (Pro Tools HD), SSL, Apogee...
Some work by daisy chaining firewire or thunderbolt interfaces, others use a PCIe card with one of more dedicated digital multichannel interfaces that connect to rack hardware containing the analog inputs/outputs.
1
Not aware of any single units that will provide that many analog outs (but happy to be wrong) Also, FYI Motu have updated their product range recently so something like 2 x 16A's or 24Ao units could fit the bill
