Cheap USB Simultaneous Multitrack Recording




want to record simultaneous tracks without an expensive pa system or beastly sound card?  i did.  i'll show you how with some cheap usb soundcards.

 i got tired of having to record one track and then another and then another when i could really do it all in one take, with much better results.  i had a couple computers sitting around in various states of disrepair, so i gutted the sound card from one and put it in another.  then using my recording software (cool edit pro at the time) i mapped the soundcards to different tracks and viola, it worked.  i hit up ebay and found some usb soundcards for about $3 each and bought about 8 of them.  using a usb hub, i plugged in 4 of them and attached a couple of different things and i was surprised when it worked much better than i anticipated.  

dislcaimer: it would seem these cards are limited to 16-bit recording.  that being said, as you can tell from the videos, it still sounds pretty good.  while i wouldn't try and start my own recording studio with this technology, for hobbyists, budding musicians, bands strapped for cash putting a demo together, i think this is a much better option than recording single tracks and having to overlay them.  thank you all for your interest, keep the comments coming, and i'd love to hear what you can make with this.

Step 1: Get USB Soundcards

first you'll need some usb soundcards.  these are pretty cheap, i think i paid $2.99 each and i got mine from ebay --> usb sound card

i might as well tell you what you will need.

1.  a computer
2.  usb sound cards
3.  usb hub
4.  audio recording software that supports multiple tracks (see below)
5.  3.5mm microphones or other audio out from devices 

some software options are cool edit pro (used in this example), garage band, and i think audacity can do this too.

as for the input, you're receiving end is gonna be a 3.5mm jack, but there are all kinds of conversion cables and jacks to help you out.  as soon as i got this working, i had grand plans of putting 6 or 8 of the usb soundcards and a hub inside a nice enclosure with some breakout cables which would extend the input jack to the exterior without having to do anything to the soundcards, and terminate it with the 1/4inch jack since i mostly use those for guitar and some of my mics.  i never got around to it, but feel free to trick out your setup with a nice wooden box (i initially wanted to use a cigar box).  don't forget to add a bunch of pretty lights.  i still have a lot of ideas...

as far as i can tell, this system is completely modular, the number of tracks is limited only to the number of usb soundcards and usb ports you have.  the most i've ever run at a time is six (i gave a couple away), but i don't see why it wouldn't work with more unless limited by your software or processing power.

Step 2: Hook It All Up

once you have your usb soundcards, you can plug 'em in.  i recommend using a usb hub to make things easier and use more tracks, but if you only wanted to record two tracks and you have two free usb ports, it's not a necessity.  

Step 3: Set Up Your Software

long story short, i started this instructable a long time ago.  i initially did a bunch of searching for ways to set this up using audacity and garage band but can't remember what i found.

this youtube video --> Using Multiple Mics with GarageBand

all you audacity users let me know how and i will include it here with credit

cool edit pro
this is the software we'll be using today.  there are countless tutorials on how to use it, (here's a youtube video) so i won't be going that in-depth other than the usb config.  i will assume you know the basics.  now then.

start a new project.
goto options --> device properties
make sure your devices are listed and in use by changing the order

once you've got it all set, go back to the session view (with all the tracks) and change the recording inputs for the tracks you want by clicking the Rec button (see pic).  to figure out which input is which (because the devices are named the same) the fastest way is to assign them all to different tracks and just hit record (make sure each track is set to record) and test them out.  

Step 4: Record Some Music

press record and do some music making!  

i came up with this a while ago and since have got some more audio equipment, however last summer on my way up to rothbury with my sister we stopped over in tennessee at my grandpa's house and he wanted me to help him with some recording.  with only a backpack full of wires and mics and my laptop, we went over to the house of ernest ferguson (IBMA Pioneer of Bluegrass) and recorded a whole cd's worth of music.  below is one song from that session.

that track was recorded with a singstar mic for the ps2, a rockband usb mic for xbox 360, cable converter for the guitar and a lapel mic stuck inside the mandolin.  all my other mics require phantom power and because i was going to a hippie convention i really didn't want to drag a bunch of quality gear with me.  i think it turned out pretty good, and Ernie played pretty great for being 92 years old, and Gene did great as well at 84.  i'm gonna put it on itunes for them so be real excited and support folk musicians.

hope you enjoy, this should help bring multitrack recording to the masses, or at least to high school students or something.  if you record something with this, give us a link in the comments so everybody can check it out!

the video i made at the beginning was recorded with my phone, so sorry for the quality.  if there's enough response, i can do it better and in hd.  if you guys have any tips for other audio softwares leave it in the comments.  at $3 a track, you can have a pretty decent multitrack recording setup for under $20 as opposed to what, $500?  thanks for reading!  and if you found this useful, don't forget to rate!

btw my site (which doesn't get as much love as it deserves) is  just had to get that shameless self promotion in there.

    So, in 2018, on macOS 10.11.6, it is possible to record more than 2 tracks simultaneously in Audacity 2.2.1! Apparently there isn't much control over which tracks to record to, it's explained here:

    1) Set up an Aggregate Device in the system "Audio MIDI Setup", as explained in the linked video for how to do it in Garageband.

    2) Start Audacity

    3) As input device, select the Aggregate Device

    4) Change the recording channels to the number of channels you have (in my case: 2 Channels from an external soundcard, and 2 Channels from the built-in microphones, makes 4 Channels)

    5) I couldn't get it working without it: In preferences -> recording, check the box for "Always record on a new track"

    6) Record, and see 4 new tracks, each recording their own mapped input!

    I am so going to do this man... was looking at mixers and this might suit me good.... might have some issues with sound quality with a podcast but good for a take along backpack recording studio :)

    Sounds good, especially considering that it's not powered mics :) Mixing and music sounds better than some bar bands I have seen/heard.

    How Can I Use this is Reaper (another kind of daw)

    This is not working for me. Please help. I have 5 mic and 5 usb sound cards connected with a usb hub. Multitrack preference order is set as in this description with 5 mics and a Wavemapper. Setup displays all channels but only one microphone is recording.

    I know this is a few years old but I have one of these but my laptop refuses to recognize it and I can't find software. any ideas?

    i know this is an old reply, but what you'd want to do, is open one of them up and check what chip its running, then you should be able to find a driver for that chip easily, although id have thought it'd be class compliant?

    well....i guess this would work, if your in a real pinch. but seriously, without a good quality sound card, your recordings are going to sound like garbage compared to most home recordings. You gotta start with good quality audio to get a good quality recording.

    you can pick up something like an old m-audio fast track on ebay for less than $20. that will let you do 2 tracks at a time, but they make units to do much much more. There octane preamp has 8 channels, which is great for live drums.
    these units are a little older so you can usually find them pretty cheep.

    just thought id share a little more efficient way of making multitracking on a budget

    I don't see why it shouldn't work, but I might try two before I bought seven. I have one USB mic and I've used it simultaneously with three of the USB sound cards before and didn't have any problem. I think as long as it's recognize as a separate audio interface it should be fine. Let us know how it goes!

    I was never satisfied with the way my acoustic guitar sounded with a one-mic set up, but couldn't afford a expensive multitrack sound card. Bought 4 of these USB cards for like $2.50 each (shipped).

    I now use two microphones - one mic dead-center in the sound hole, one might at the beginning of the frets, one mic panned hard left, one hard right. While they are essentially recording the same thing, the slight differences make for a beautiful stereo sound. Maybe not studio quality, but much better than I was getting before.

    I've also experimented with a three input setup - the mics set up as above, and my guitar's pickup as a third input, dead-center in the track. It shows promise, but I haven't got it to sound quite right yet.

    I've got a lot of experimenting to do with mic positioning, how far to pan the inputs left/right, etc, but I can tell you now this was the best $10 I've spent in awhile.

    Thanks so much for this instructable! Now I need to start writing something someone would want to listen to!

    so far its working good, ill be recording some bands for fun soon. as for noise and feedback i have gotten none. no hissing, clean clear sound. and if you do have a little bit of noise, hisses, people s's sound like hissing snakes, or it sounds a little off there is the d ess'er, reverb, pop and click edit works great. the only one that i can get to work with this setup


    7 years ago on Introduction

    How is the quality on these adapters? Is there a lot of noise?

    Certainly I'm not expecting it to be similar to a soundblaster card or anything else that is a few hundred dollars, but if anyone has ever plugged in a rock band / guitar hero mic (they are USB) you get a surprisingly clean signal, and I was wondering how it compares to these cards.

    You get what you pay for, but as for noise, it's pretty clean. The audio from the live demo wasn't mastered or anything, and if you can see the signal is pretty low when I'm not singing or playing. And I did it with the cheapest mic I had. Again, this isn't awesome quality gear, but for the price, I think it works great.


    Reply 7 years ago on Introduction

    Awesome! As I said, I'm not expecting anything stellar, but I am hoping for rockband mic quality, so that's good to hear. Thanks!

    dont get me wrong here , im impressed with what you have achieved here.

    but the recording quality on those cheep usb audio cards is generally quite poor

    at least the ones ive seen have been poor , lots of noise and hiss in the recordings

    when you compare it to a recording done with an m-audio card or my yamaha 01x

    do you find that to be the case with these usb audio cards you got ?

    either way its a very cheep way for any budding musician to get a start on recording.

    top stuff :)

    The M-Audio interfaces I'm familiar with only have a few channels, until you start shelling out some $$$. I recommend them though, they sound great, have phantom power and onboard preamps, great if you're just doing one mic and one guitar.


    7 years ago on Introduction

    just for an update.

    so far great results, clean sound, easy setup.

    now for the software.

    Cool edit pro seems to be the only usable software. with some cons
    -no monitor live playback
    -if you change one hardware unit, it changes every track that is using other hardware.
    other than that works great.

    FL studio
    -does not seem to comply at all with multi track recording

    cant seem to get the program to do multi track to work at all.

    anyone please q in with some info
