Hi Mark,
Many many thanks for your valuable tutorials, it was quite helpful for a
person like me. Hey I am a singer. some of my songs are uploaded to you
tube. please type Niranjoy and check out in you tube,
Coming
to the subject - I am using Audacity for almost 2 yrs now. During my
initial stages of recording my singing and recording using Audacity I
just plug my conventional- unidirectional mic to the mic input of my
laptop and using a headphone out from it. All these were recorded
without even listening / hearing my own voice while recording (yes of
coz there is option to listen while singing in Audacity, but due to the
latency factor I don't use it at all). After seeing your tutorials on 6
things you should know about home recording, I am now a lil excited and
anxious, frankly. Since I m finacially not that sound I couldn't afford
all that expensive mixer having phntom powered one. I very recently
purchased a simple 6 channel mixer which has simple line inputs and 2
outputs (no XLR, no phantom power). Luckily it has headphone output.
(image of the mixer is attached).
what I m doing is ----1. mic terminal connected to one input channel of the mixer
2. output from mixer to the mic input of the laptop (as shown in your 3/6 things you should know about home recording tutorial)
3.output
from laptop to another one input of the mixer (as shown in your 3/6
things you should know about home recording tutorial) 4. inserted my head phone to the mixer's headphone socket
4. Opened Audacity- imported a karaoke track - press record button and starts recording my singing. In doing so, the recorded track (2nd) is not only my own voice, but
mixed with that of the karaoke track. This is my big problem.
So,
please, therefore teach me in this regard. Is using an USB sound card
solve this issue, if yes please teach me how to connect.
I will be so much thankful to you, please help me
with kind Regards

can i plug in my guitar, my mic and my drum mics in the audio interface or a mixer would be better?

if the audio interface connects via usb is there any need for the 48V of phantom power?

For my studio, I use a Lexicon Alpha which has two instrument front inputs, two XLR inputs in the back. The only downside is that it is USB powered and not phantom powered. I feed that into a Behringer mixer on my system when I was to record. It works well with both my PC and my Mac (which is my main recording box).

HI, i just bought a LINE 6 KB 37, but just now I discovered your tutorials,
Do you recomend it? i hope i havent made a bad choice.

Thanks !

hello.. is there a difference on latency? i mean between i play my guitar through pc mic/linein jack + asio (without audio interface) & play guitar through an audio interface?.. is that the use of audio interface?.. thank you..

How about..hmm m can you connect a mixer to the sound card then to the computer?

You are now describing parameters which are not relevant to your initial point. Background EMF has been considered in the USB design, this is why the output and input stages of the USB path has common mode rejection opamps, which deal with this problem. Since you did not provided a valid source of information on the topic. I did it myself and contacted Henk Muler Principal Technologist at XMOS Ltd. In his words "Data integrity is neither guaranteed, nor maintained, nor is it a problem"

Under normal conditions (like home use) an USB interface will work perfect. But in the field (like a party with orchestra) you will have a lot of cables running different voltages, including mains. This will create a very noisy (electrical) environment. Also, the computer to which the USB interface is connected might have some lags, as many will use if for something else besides recording (while recording....).

Can you PM me your peer reviewed source for your claim? I'm curious to investigate the validity of your statement. I believe what is important to establish is the actual possibility of data loss over USB and whether data loss is detrimental to the audio recording as you suggest. I'm not disputing that isochronous transfers do not have data guarantee, but I am challenging it's occurrence and distortion properties.

Also, i do not recommend USB for any serious audio. USB audio class uses isochronous transfers. These DO NOT guarantee the data integrity but only data timing. On the other hand bulk transfer (used for example in external hard drives) do not guarantee timing but data integrity. In practice it will work fine with a good computer. But any error on the cable will essentially destroy a recording. An external recorder is mandatory for anything serious.

Mixers with USB connectivity usually have an Audio Interface circuit built in. However they only provide a stereo or 2 x mono channels of recording though that path. In most home recording applications this is usually sufficient, but just beware of this limitation and that you cannot record more than the two channels at one time though USB. Basically every other channel is mixed into the main stereo pair on the main output of the mixer.

Thanks for your videos! I have a doubt,I would like to ask you: Can't we use a mixer with USB connection? And abdicate external Audio Interface? Does the mixer with USB connection have already an interface audio?

I gather you are talking about Audio Buffer Underruns. In my opinion I would say "No, not really" since I believe this is a processing/latency issue. Since the compensation for underruns is done though software it suggests that it is a driver and DAW software issue. But considering that the Audio driver is usually packaged with the Audio Interface, it can be said that an Audio Interface can be seen as part of the solution even though maybe not directly. PM me if you want to discuss this further.

Yes your descriptions is correct, Laptop, Audio Interface & Mic is all you need for vocals and further expansion. Also most keyboard MIDI controllers now come with USB connection too. But if they do not your can use the MIDI connection on your Audio Interface, provided it has one. The USB Audio Interfaces would also become your sound card.

Thanks so much for these videos. Just to make sure- if I'm only recording vocals, I can have my entire system be: Laptop--audio interface--Microphone ? And then if I want a keyboard with MIDI connected into the system, it just branches off of the Audio Interface? If I use an audio interface, there's no need for a mixer? What about a sound card? Thank you

Phantom power requirements are not always 48V. Most microphones do not use the full 48V, you should probably look at the requirements of your condenser microphone you have or intend to buy to make sure the interface has the required power for it. However since you are using a dynamic microphone then phantom power is not required. Neither is midi. The other thing about midi is that most modern midi devices have a USB midi connection, so you should be fine there too.

Awesome Tutorials, can't wait to start recording on my own! Still one question left: You recommend, that the interface should have MIDI In & Out and 48V Phantom Power. I thought about buying a low budget interface (Behringer Xenyx 302), with just 15V Phantom Power and no MIDI. Would it still be good enough to record Vocals and Acoustic Guitar (with a dynamic microphone)?
