I don't know where you read about USB interfaces needing to "compress the sound", but it's nonsense. For your application two channels will do; at 96 kHz and 24 Bit that's less than 5 MBit/s: even USB-1.0 can handle that without compression. and USB-2.0 is already more than ten times faster, so even in multichannel applications it's often plenty good enough. ...

I don't think it's coming from your microphone because there is a small stereo width to the noise at all frequencies. The microphone can only produce perfectly mono sounds. Here's an enhanced spectrum of the noise: - Very noticeable are the sequence of peaks at precisely 1kHz, 2kHz, 3, 4, 5, 6, 7 (not 8), 9, 10, 11, 12kHz etc.... These are very unlikely to ...

It was bound to happen before long: - Not easy to achieve technically and I can't vouch for its quality but I know two guys who have facebook "liked" this product and one of them does live gigs. The trick is to efficiently take a slice of the 5V offered from the USB and efficiently convert it to a higher voltage that is more practical for audio mixing such ...

That is the result of bad isolation of either the DAC or the ADC. If the internal circuitry of the interface and the actual capture or playback circuitry share a common power supply, the operation of the electronics itself cause a distortion to the power being supplied to the capture or playback circuits. Capture and output both rely on a fixed reference ...

A good digital signal should either get there or not. Minor differences in cable quality are not going to have any impact at all other than latency. Latency is simply the delay in how long it takes to get to point a to point b and won't impact the sound quality significantly. USB is a digital signal, so a "premium" USB cable is a load of crap. There is ...

I had a quick look at your device, it says the USB input is 16 bit / 48 kHz and that the device uses asynchronous sample rate conversion and 24 bit DACs @ 192 kHz. S/PDIF and Toslink are identical at the bitstream level and both are consumer variants of AES3 which supports 16 or 20 bit at 44.1 or 48 kHz. the HiFace2 says it has very good clocks, which ...

Focusrite Scarlett and an SM57 should be just fine. Combine it with a DAW like Ableton, Pro Tools, Cubase, Reason, Logic, etc, and you'll have a good setup. leftaroundabout mentioned many of the main reasons so I won't repeat them all, but the main reason is that USB2 is often not the bottleneck for recording applications unless you're doing extremely ...

The ProFX8 will let you record only a stereo channel (or 2 mono) at a time. I am not familiar with Traction, but in Cubase you can go to menu Devices > Device Setup and choose the Mackie from the first option field (Asio driver). Then you might need to go to Devices > VST Conections to route the channels to the right input. Here you can choose in ...

It depends on your device. Some Android phones support a headset input through the headphone jack (such as through this device [Traveler Guitar MI-10]). In that case, a simple adapter can allow you to feed an audio line in. Other devices allow what is called host support for USB. If this is the case, then you may be able to use a USB audio interface if ...

A few quick notes At stage volumes, you really really want to be using a SSD Drive. You will have issues with normal platter style HDD's at stage volumes due to vibration Even with a SSD, you're going to want to sit the laptop on some vibration damping type material. Grab some mopads (designed for acoustically decoupling speakers) and sit it on that, ...

If you won't be using it on stage or with other MIDI gear apart from a computer, a USB only on your keyboard controller should be okay. (Personally I find the connection more stable) Modern PC's should allow you to route the MIDI signals to other USB-MIDI devices plugged into the PC within the OS or software. In my experience with Macs, you can do the ...

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: ...

Just because someone got upvoted on reddit, that doesn't mean it isn't total and complete nonsense. OK lets get one thing clear from the start. S/PDIF and USB are simply data transports. In reality they have absolutely nothing at all to do with audio, they are just ways of getting data from one place to another. That data might be related to audio, and in ...

Well, it turns out that our worthless electricition did not properly ground the outlets in this room - I used a tester to verify this. This would explain the humming noise in my recordings and also some other unmentioned audio problems I've had in the past. I'm going to fix the grounding for the outlet and assume this problem will be solved. I was able to ...

As AJ Henderson and Warrior Bob mentioned, those cables are also MIDI interfaces. I have several of the cable-style MIDI interfaces, as well as an old eMagic AMT8 and a MOTU 828 MK2. A few of my synths with USB interfaces function as USB-MIDI interfaces, but I rarely use them for that purpose. I also have the Elektron TM-1 interface for my MachineDrum. For ...

The cable includes an in-line MIDI adapter. (MIDI and USB are not compatible signals.) M-Audio is a respected manufacturer while the other one is a no brand adapter. It might not work as well or might not support as many channels, but at $5, it's hard to go wrong giving it a try and the reviews seem to indicate it will work for your purposes. If I had to ...

I find such arguments generally invalid. The whole point of digital is that the signal is transmitted as-is, without loss or coloration. Now, one might make an argument from the standpoint of interference (e.g., if you're running your USB cable alongside a thinly insulated power cable with a 10kw load), but such arguments are silly as well. If someone out ...

Echo make reliable interfaces and I'm gutted they've killed off much of their lineup. I'm hoping there's an Echo8 in the works.. Apogee Duet seconded. MOTU's Microbook looks promising but I'm hearing from people having trouble.

Does your Mackie have a USB output? If it does then you may need to load drivers onto your PC so that it recognizes the mackie mixer. These drivers probably came with your mixer when you acquired it. If it doesn't have a USB output then you'll need a USB analogue to digital converter maybe like this: -

Your "MIDI-USB cable" is a MIDI interface: a computer-addressable device that accepts and sends MIDI messages through MIDI DIN jacks. In this case both of the indicated devices are specifically USB MIDI interfaces. Featurewise, there's likely no difference between them. The price differential is probably due to name and build quality. Sometimes the fancier ...

I have the same USB midi keyboard and use it in both KDE and Ubuntu Studio using software MIDI routing available in the assortment of JACK packages (search for qmidiroute). I don't believe ALSA sound has any functionality for MIDI, so best to switch back and forth to use JACK for MIDI and instruments, and ALSA for playing media or hearing game sounds. USB ...

There is! Generically this is called an audio interface. These most commonly include ADCs/DACs and analog preamps, but an audio interface with a digital input (such as S/PDIF or optical TOSLink) will give you the "digital to digital" connectivity you're looking for.


2

Generally no, using multiple inputs shouldn't lower quality as long as the USB controllers still have sufficient bandwidth for the devices to function. If you use a hub to connect everything, then you may run in to data rate issues causing latency or outright failure, but in general, the data is digital and should get from point a to point b alright. There ...

Old question, I know. Use an USB isolator like this: Less than 10 dollars on aliexpress. What it does: Isolate ground (lift ground) on the USB connection with isolated DC/DC converter to eliminate ground loop/noise.

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