Capture Audio through USB interface - How to adjust input level?

My USB turntable offers Line In and USB in order to connect it to my iMac. I would prefer USB but there is no way to adjust the input level. This only seems to be possible with Line In. Is this correct or is there anything I should know?

The only way to change levels with an A/D audio interface is BEFORE the analog/digital conversion.
If your turntable outputs USB (a digital connection), then the A/D stage is within the turntable, and any level adjustment will have taken place within there (I'm betting there's a level adjustment trimpot somewhere inside if you can't see any knobs from the outside).
This shouldn't be a problem, though, because the maximum levels a vinyl LP can produce are limited by groove spacing and the sheer amount of vibration the needle can take before jumping out of the groove. The turntable will have been adjusted for this at the factory (I'd assume), so you can safely use the USB out - the turntable's A/D stage is bound to sound better than the $1.50 A/D-D/A chip built into the computer.

Airport express & digital audio through usb

Can airport express stream digital audio through usb to use with a usb DAC?

No. Digital optical audio is only available via the AirPort Express' audio port only.

HighRes Audio through USB

I had the Z2 since last year. Because my old headphones (Sony MDR-F1) are nearly dead and the Z2 supports HighRes Audio through USB (external DAC) I bought the Sony MDR-1ADAC. I was happy, everything worked well and the headphones are killer. There were just two tiny things I didn't liked about the Z2:a) The haptic of the frame was not that goodb) the USB port behind the cover on the left side - very bad if you want to put your phone in your pocket while listening to music Thus I bought the Z3+ When I connect my Sony MDR-1ADAC through USB nothing happens on the Z3+ and music, etc. is still played through the internal stereo speakers. The Z2 had a setting that enables "external USB-DAC" and the Z3+ doesn't BUT the Z3+ additionally (compared to Z2) supports HighRes through Bluetooth and DSEE HX. So the Z3+ has better support for HighRes Audio but at the same time less support. What the heck is going on Sony?

I've recently had to add
Enable=Source,Sink,Headset,Gateway,Control,Socket,Media
to /etc/bluetooth/audio.conf. And then restart the bluetooth service / daemon.
# systemctl restart bluetooth.service
# or, whatever ...
# rc.d restart bluetooth
Then it works again. This may just be a systemd artefact, however.

Trying to record Stereo Mix with a monitor through my headphones. Using Screenium to record Audio and Video, using Avid MBox Mini with MXL 909 Microphone for the audio through the interface.

Basically, what I am trying to do is this:
Record my screen through Screeenium, record my voice as audio through an Avid MBox Mini (interface) with a MXL 909 microphone to pick up the audio. I have all that figured out. I'm able to efficiently record my audio and screenplay through these instruments and programs. What I am having trouble with is the stereo mix. I am running into a slew of problems here... My goal: Add on the audio of a game that I am playing (for example, Amneisia) so that the audio for my game will be picked up internally, and not through the speakers to be recorded through the microphone. I want there to be no external sound except me talking into my microphone. I also want to be able to HEAR the audio of the game through my headphones (and if possible, myself as well, through a monitor maybe?)
Problems I have run into so far:
-Haven't gotten it to pick up in game audio at all while using headphone. Can't figure this out
-Downloaded soundflower, have the output as soundflower. Not picking up anything, will put all my sound and midi settings at the end.
-When I do record through my microphone, it is only picking up a single channel (left earpiece only, no right channel)
-I have figured out it is NOT the equipment, I use Pro Tools and am able to pick up both channels with my mic, recorded a few tests. It's settings and I can't figure it out
-Trying not to run 16 million programs while running the game, will cause lag.
Summed up:
Trying to record:
-Audio from gameplay of any game I am playing through alternative route of speakers (do NOT want to record game audio through speakers, internally)
-Record voice through Avid MBox Mini and MXL 909 microphone.
-Record screen gameplay through Screenium
I followed a guide that told me to achieve "stereo mix'' I need to download soundflower and follow "X" steps. That is done and these are my current settings:
Audio Midi Setup - Stereo Mix custom Aggregate Device, Soundflower (2ch) selected, Avid Mbox Mini selected, Soundflower Output #1 has 2 channels (1-2), using Avid MBox mini for "Input" in order to record. Using Soundflower AND Avid MBox mini as "Output" in order to hear the sounds and replay game sounds (could be the problem? Maybe?)
Sound Settings - Output Stereo Mix (custom channel) Input Avid MBox Mini (recording)
I'm hoping this isn't too hard to understand.. I'm VERY bad at explaining information regarding computers.. It's hard becuase I don't understand it. I can clarify anything that I am able to, so any help on finding certain things would be greatly appreciated.
My computer: Macbook Pro MAC OS X Lion (11G63) 10.7.5 2.4 GHz Intel Core i7 4GB 13333 MGz DDR3 (If any of this is imporant)

Hey guys,
I tried to do some research and it looks like you need to have an external device and its drivers, such as an external microphone, installed on the computer to record audio that can be saved as a sound file. Another Suggestion is to try an auxiliary spliter for your headphones and external speakers?
What software are you using to record your game?
If anyone knows anything different, please let me know.
Thank you for being a part of the Lenovo Family,
Catie

Want to get a new Macbook and import audio through USB? Look here.

FWIW, as I was reading many of these posts, a lot of folks are suggesting that you NEED firewire for audio interfaces. Here is a link to twenty (USB) audio interfaces and that is just at one site. I myself record hi end audio for film using a M-Audio Fast Track Ultra (8 in and 8 outs) along with Logic and Final Cut Pro. Firewire is great, can have less latency, and a lot of users still have gear. I won't get into that debate, it's been beat to death. Just wanted to be accurate to any budding musicians, etc. who might be scared off by all this talk re: Firewire a necessity for pro audio. Latency (a problem 'sometimes' associated with USB devises transferring slower data) is old news. Technology has come a long way since the days of a USB 1.0 MBox. Get a new Macbook, a good audio interface, write a great song and you're in business -- all in style with your new sexy MB. Here's the link: http://www.sweetwater.com/c695--USBAudioInterfaces

I'd still beg to differ, and I would hazard a guess that most people who work in Audio would agree that firewire interfaces are as a general rule of thumb, far superior. Now a reason that I'm not too inclined to recommend M-Audio is because I had an M-Audio USB interface, and it was nothing but trouble, pops clicks, dropouts, high on the CPU, it would reset the USB bus and cause crashes, often forcing me to reboot mid session. Plus the MIDI interface never did work!
I hope they've cleaned up their act since then, and I guess if you can get work done on your interface that they must have done.
I do find it odd though that the company who Apple partnered with to release some audio interfaces that work seamlessly with Garageband and Logic chose firewire, so if you buy a new macbook and want to use the interface that Apple recommends to use with garageband you can't.
Now one of the reasons I have a macbook, is that last year my iBook died, and I needed a new notebook to go with my MOTU interface, I could just about have stretched my budget to a MBP, but seeing as they used the Lucent (Agere) firewire chipset, there was a strong chance that any decent firewire interface wouldn't work with it, and I've heard that the new MBP uses the Lucent chipset, rather than the more dependable TI one, so there's a chance that professional audio may have to skip this whole generation of notebook refreshes, that is until Apple start using a decent chipset again.
And I'm sorry, the argument that Pros would only use the Pro machine seems a little naive (see above reason), sometimes portability is a pre-requisite for a persons needs, the portability that say the old 12" Powerbook had, which many still miss. Plus as far as portability goes many firewire multi channel interfaces are bus powered, something that AFAIK you can't get with USB.
But all audio interface disagreements aside, one thing that USB does not have, and I don't think could have, is DSP, like the SSL Duende, the TC Powercore, the Focusrite Liquidmix. All three which come in a variety of flavours, including the less powerful, but more price friendly variety, perfect for end users who want a bit of class but without paying the earth.

Can't adjust input level when using usb microphone

Hey guys,
I'm very familiar with this version of Garageband, and just started using a Blue Snowball USB mic. When I plug it in and set the drivers accordingly, the input volume slider is greyed out, making it inaccessible. Is there a trick to being able to adjust input volume?

Option Click on the Volume slider icon in the menu bar and choose Sound Preferences. Choose the interface and you should be able to see the input level.

How to adjust line level input?

Anybody know how to adjust the input level of my 1/8" input? Everything's coming in too hot.

Man I just posted that - did you actually read it??
Create an Input object in your environment.
Open environment (command+8)->New->Channel Strip->Input
Then just turn the slider in your Input object down by some dB.
I forgot to say: Then insert a Gain Plug In from the Utility folder into your Input object and turn down the gain to your liking. Sorry for the confusion...

How to Set Input Levels with FirePod and GarageBand

Hello ....
I/ve got Garageband and my Firepod 8 channel interface working ... but I need some tips .. especially on the relationship of input levels between my Firepod and Garageband ....
When I am setting input levels for a recording ... where should the input level be on the track in Garageband? .... Is that volume setting only for playback and mixing? .... or is it for the input as well ...
Thank you ....

Where should the initial input levels be set? ... Would you use the loudest
part of the song to do this? ...
Yes, as loud as possible without lighting the FP's clip leds.
When I mix the final product ... and change the volumes on the different
tracks.. aren't you then changing the input levels?
No, you're changing the output levels.
can't you red line and overload the track?
Yes, that's why each track has a fader, so that you don't clip.
Is there a master ouput level indicator
Yes, right over the Master Volume slider.
I guess you can't just put each track as loud as you want ... correct?
As loud as you want without clipping.
I would strongly suggest doing some web searches on "Mixing and Mastering" to learn more about how to mix, there's a TON of info floating around the web.

Self adjusting input level on built in mic?

anybody?

Self adjusting input level?

my bf & I tried to set the input level of the built in mic but as we talk it creeps itself back up to maximum & causes feedback since the speakers are so close to the mic. i have a macbook & he has a macbook pro. we've tried using headsets & headphones & getting ticked because there's always something wrong! either there's feedback or one of us is too soft. any suggestions?
Macbook, MacBook Pro Mac OS X (10.4.7)

Hi Kirsty,
I find that may System Preferences> Sound > Input volume adjusts back to a lower setting on every chat.
I have not found where this is set to be a permanent setting to where I want.

QuickTime only plays its audio through my interface

I installed the Windows Media plug-in for QuickTime and I can now stream and preview content I could not have before. However, for some reason, the streaming content I wish to listen to (audio from a radio station) only plays through my audio interface.
I would visit the web page that has the streaming content and their little commercial with video plays fine through my internal speakers. However, once the content I want to see starts playing, for some reason it plays through my audio interface connected via USB. The thing is, not only have I made sure that the audio preferences are set to 'internal speakers,' but at some point the content I want to hear actually played through my internal speakers! What am I doing wrong?

That's weird! The content won't even play if I try unplugging the USB connection to my audio interface. It says "Unknown Error -2004."

No sound when streaming audio through USB to car stereo *solved*

Short version: Many months ago my wife and I had iPhone 4s with AT&T and my phone would playing streaming apps (Pandora, Slacker) over USB to my Pioneer head unit and my Ford SYNC while my wife's would not. There was no error given, it appeared to be playing fine-- there would just be no sound.
Fast forward to present and I have a Verizon iPhone 4 and I am getting the same issues as my wife was having previously.
After much forum reading about iOS4 breaking this functionality for many people across the globe with many makes and models of stereos and cars I realized I was not getting the same error as all of these people. I was getting NO error at all; I just wasn't getting any sound out of these apps.
I read a post about how a random song would kick on when they connected their phone to the car, then it hit me. My old iPhone used to do that. Then THIS hit me. I do not have any mp3s synced to this phone. Nor did my wife back then. So I threw a handful of songs onto my iPhone and sure enough it immediately chose a song at random, started playing it and then I switched to Slacker radio and it faded down the iPod song and started streaming the audio from Slacker.
tl;dr version: If streaming apps are not playing any sound through your USB cable. Make sure you have some songs synced to your iPhone.

I found a solution, reset all settings. Settings > General > Reset > Reset all Settings
Fixed the problem, now back to properly streaming music!

System sounds through internal speakers but other audio through USB Soundcard

Hi there,
I am having a bit of an odd problem. I have a USB sound card and when using it plugged directly into my Macbook Pro retina's USB slot all audio comes through the sound card however when using the sound card connected to a USB hub almost all sounds except for system sound come through the speakers (e.g. deleting a file in finder noise comes out the internal speakers or sending an email sound etc.). Does anyone have any ideas on how to get all the audio to come through the sound card or as to why this is happening?
I have checked system preferences and it says USB Audio Device is the output. I have tried changing it to internal speakers and back again but this hasn't fixed the issue.
Thanks
Ben

Applications -> Utilities -> Audio MIDI Setup; select the desired output device and click on the gear icon at the bottom, select 'Play alerts and sound effects through this device'.
