Guitar routed through Amp into audio line-in

Okay, everyone says that you need to check your sound prefs and set them to the line in on audio. I've done that with just a guitar and nothing worked. Then people said that you need to have it amplified, so now I connected my guitar to my amp, then from the headphone jack into the audio in port and turned on the line in input in sound prefs. I still don't get anything for sound on my powerbook G4 or garageband. I can get the built in mic to work but not the line in. What's the point of a line in if I can't get anything? Everyone suggests a usb interface to connect a guitar but Guitar band help says I should be able to just connect to the line in.

if that's all you had you couldn't plug anything IN to it ;)
you should have a headphone-OUT, and a line-IN, make sure you're using hte line-IN, then set GB to use it:

Condenser mic through PowerMac G4 audio line-in

I just picked up a MXL M.A.R.K. condenser mic and a Rolls Mic Power I 48V phantom power supply. I'd like to start podcasting using GarageBand. I've connected the mic to the PowerMac G4 audio line-in port and select Line-In in the GarageBand preferences. However, the mic audio is barely discernible...even with volume inputs all the way up, which of course increases the noise. Anyone have any ideas how to take advantage of this condenser mic? Is Griffin's iMic required? Does the phantom power supply appear defective?

Why can't I get stereo sound recording to iMovie through audio line in?

I am recording some keyboard music from a digital keyboard (Yamaha pf85) into iMovie HD 6 on my laptop through the audio line in. I have connected Output I from the keyboard to the audio line in using a mini jack adapter. This is supposed to record the music in Mono, but it will only play back on the left side of the spectrum. There is no right side sound at all. The keyboard has twin outputs, so I have also tried connecting Outputs I and II to the laptop's line in, using a twin mini jack adapter, but the music still only plays back on the left side. What's happened to the right side?
I have transferred the movie to my desktop Mac (PowerPC G4 with OS 10.4.11) but I get the same problem.
I've tried exporting the movie to QuickTime, but still the same problem.
What am I doing wrong? How can I record/playback the sound on both sides of the spectrum?

Thanks for these suggestions, which are blinding but have not solved it.
1) All cables OK and fully inserted.
2) I tried recording a voice over into iMovie using a USB mic/headset and that was in mono but played back through both channels, so laptop and iMovie are OK recording with USB.
3) I tried recording from the keyboard into iMovie and QuickTime on the laptop in three different ways through line in: first using both Outputs, then using Output I only and finally using Output II only. On all three occasions, the sound played back on the laptop through the left channel only. The keyboard itself has two inbuilt speakers and a headphone socket and both are providing mono sound through left and right channels, which suggests it's not faulty.
I then tried recording sound only from the keyboard into Quicktime on my desktop Mac, using the same cables and adapter. Left channel only.
I guess this means either the adapter is faulty or it's something to do with the way my keyboard outputs sound. I'll try your other suggestion. Or maybe I just need a hardware interface to route the separate channels. That seems excessive for what I want to achieve.

Am trying to record a basic guitar track while I sing along. I don't want my vocals to be recorded at the same time but the internal mic seems to be picking up the vocal and guitar sounds. I tried System Preferences, Sound, Line In - Audio Line Input.

for me it turned out that the jack into the iMac was loose. Once I fiddled with it everything worked okay

I connected my brand new iPod Classic 160 GB to my brand new Sony home entertainment system through the headphone jack (to the audio line in). The volume is ridiculously low. Can somebody help me out here?

Make sure the volume on the iPod is turned up fully, since this will affect what you hear through the stereo.
Make sure Volume Limit is set to full. (From Main Menu, Settings/Volume Limit)
If you purchased your iPod inside the EU (European Union), then the maximum volume from the headphone jack is lower than elsewhere in the world. If this is the case, buy yourself a 30-pin Dock Connector to 3.5mm jack lead, such as the one linked here...
http://www.amazon.co.uk/Decrescent-Connector-Stereo-Auxiliary-iPhone/dp/B007NIE5 EE/ref=sr_1_1?ie=UTF8&qid=1386012456&sr=8-1&keywords=30+pin+to+3.5mm
That connector will take a higher volume out (than the European Union's output) and that will be louder (and hopefully loud enough) through your stereo.

Faulty audio line-in port?

Hi, I've just bought a 'Monster iStudioLink' lead to record a guitar onto my Mac using Garageband, but something isn't working!
I've gone into System Preferences to check if there is a sound input and the iMacs internal mic is working fine but theres no audio line-in signal.
Does anybody know if there is a way that I could check if the line-in is faulty or am I doing something wrong?
Thanks

First make sure you are plugged into the
imput jack not the headphone jack
(Ive done that many times)
If you are going direct from your guitar
you may need to go through a pre amp first.

Audio line -in : doesn't seem to be responding

Hi
My audio line-in port doesnt seem to be working any more.
Does anyone have any advice to help me trouble shoot this issue.
Ive already tried third party recording apps and a new set of mic-headphones but still nothing appears to be coming through.....it worked fine previously and was used often.
It may be an emac hardware issue or a system issue where i updated to Tiger a few months ago.
But perhaps it's something else !?
thanks for your time.

1. The type of headset im using is manufactured and ubiquitous for use with any pc or laptop
see for example :

or
http://www.techfresh.net/wp-content/uploads/2007/11/plantronics-mono-headset-for -internet.jpg
or
http://thevoipgirl.com/wp-content/uploads/2006/08/headset.jpg
which are close to the ones i use. I know they're the cheap end but they are very common - Don't they just get their voltage from the mac itself ??
Also
2. Mine worked fine until recently - which means i was able to speak into the mic and hear it in software and adjust the audio input level in the O.S. sound prefs and now can no longer do this because when i have line-in selected as my source it's not showing any reciept signal in the display level indicator.
The simple fact that i was previously for several years able to operate one of these mic head-sets suggests that the issue must lie elsewhere and is has not been about the headset amp level as you suggested- My concern is that it is something to do with the OS Tiger which i recently updated to .....simply because it's the only major change i have in the recent past - i can't think what else it could be or what trouble shooting procedures to follow on this type of problem....

Audio line-in buzzing sound

hello guys ! i just bought a macbook last month and currently still learning on how to get used to mac.as a guitarist im very exited to try out the GarageBand.after i plug in the audio jack from my guitar to the audio line-in port,i found out that there is no sound from the strings of my guitar.there is only the buzzing sound.the input level also shows a not static level instead of steady level.what do i have to do friends ??
forgive me of my language as english is not my main language
thanks !!

Hello,
Most likely, the output from your guitar is too low and therefore sounds like silence from your Macbook. You will need to amplify your guitar output to work with your MacBook. Since you are a guitarist, you might already have the right equipment--connect your guitar to a preamp, and then to the macbook. If you don't have a preamp, I think you can plug your guitar into a regular amp, and then connect that to the macbook.
* There are two kinds of input signals, distinguished by levels. Commonly, they are called "mic-level" and "line-level." Most guitars pickups will output mic-level, which needs to be amplified to line-level to work with computers. MacBooks only accept line-level inputs.

I have used an acoustic guitar w/ preamp with Garage band on macbook, so I can tell you that it definitely works.
Rock on!

Recording a class of 30 kids singing to a guitar track I laid down on Garage Band. Severe distortion because they have to hear the guitar track through a set of speakers..

I had a big setback today on a project I've been working on. I recently made my first recording of my own playing and singing, a guitar track and a vocal track of a children's song. When I recorded the guitar track, it took me a whole day to get it right. I used the metronome through earbuds. Then I listened to the guitar track and sang into a Snowball mike to get the vocal track down. Played separately or together, they came out crisp, clear, no dostortion. I made a CD of the song by sending the song to iTuines, with and without my voice so the children could practice to it. I taught the song to 30 fifth graders so I could add a vocal track of them singing. My plan is to use it as the music for a slideshow I'm making for their elementary graduation. I'm a mom, not their teacher. The teachers of the two classrooms have been generous in letting me teach the kids the song, and setting up 45 minutes for me to record it. Did the recording of the kids today at the school. Two tracks of all 30 kids doing their very best to cooperate. They sang well. I opened the garage Band file at home and it is such poor quality audio that it is UNUSABLE. There's a lot of fuzz and distortion. I can probably get their teachers to let me have them again to give it another try, but I better get it right. When I recorded my own voice to the guitar track, I monitored using earbuds. I can't hook 30 kids up to my Macbook with earbuds. I played the guitar track from speakers and held the microphone out toward them, so the mike was between the speakers and the kids. The speakers and mike both faced the kids. They sang really well, so it was pretty disappointing to find the recording sounded so bad. My guitar teacher tried to help me figure out what to do, but he thinks it is going to be very tricky to get it right since the kids have to hear the guitar track to sing it. I'm considering playing the CD I made of the guitar track from a boom box behind the kids and just recording the kids on a separate project file and losing the ability to edit, and probably losing most of the guitar quality and volume. But I won't know if it works until I have 30 kids and 2 teachers and all my gear set up to actually try it. Whatever I do, it has to work on my next try. There's very little time left and no budget. I thought my Macbook Pro and the Snowball, purchased at the Apple Store, would be enough.
Please advise. Thanks.

Very difficult recording situation. I would probably just record the kids with you playing live guitar.
You could do the boombox with the kids and set it up so the kids hear the guitar but try to get as little as possible of the prerecord guitar on the the track. Then either mix the kids recording with the original guitar track or add a guitar track to the kids track later.
When you do the recording of the kids bring headphones to monitor levels. Also make sure you're happy with the track before you leave the school.

Connect iPod to MacBook Pro audio line-in port?

My 1st Gen iPod's Firewire port fried recently; it still delivers a charge to my iPod but won't allow it to mount. I can still listen to music with the headphone jack.
What sort of cable can I use to attach my iPod to the audio line-in on my Macbook Pro?

I also have this problem but with a slightly different twist..
I was using my plantronics (old ms gamevoice headset) with 10.5.2 and it worked, then installed the m-Audio Firewire Audiophile beta drivers and neither the audio-in or the m-audio audiophile line-in cause any VU-meter response (nor input) whereas the standard inbuilt microphone does.
After uninstalling the m-audio drivers the situation is still the same.
Oddly - if I plug in the headphones into the line-in (rather than microphone) then speak into them I actually get input audio (and VU-meter response) through the MBP's audio-in.
So the story about no power is used (hence the headphones create enough to register the sound) sounds about true... very annoying as I thought my old headset had died and went out and bought a new one.. that still doesn't explain the audiophile input issues..
Now I fully expect both companies to point fingers at each other.. I don't care - just get it fixed please.

What is the "Audio line in" port for?

I have a microphone headset but plugging the mic cord into the audio line in port does nothing. Similarly, when I tried plugging a cable from the "tape out" of my audio amplifier into that port for dubbing purposes, nothing happened. In both cases I can achieve what I want using an iMic and a USB port. So what's the audio line line port for? How can I use it?

Check your Sound settings in system preferences and audio midi set-up, Brian. It may be that you have it set to accept sound in through USB at present. Another possibility is that the port has "stuck" on "optical input".

13.3" MBP Audio line in Question

I have a 13.3 md-2009 MBP and want to do some recording on the laptop. I want to transfer some music from LPs to the laptop but do not know whether the headphone/audio line in accepts stereo?
I thought I read that it only will record in mono, but the separate audio in line on the 15" MBP will record stereo. Is this true? If so, how else can I record stereo into my laptop? Should I use something from M-Audio?
Thanks

hmmm, so... what i have set up now is a tv next to my imac 27 and alot of times ill play games late into the night at which time i will through on my headphones... before i had the tv it was easy.. all the sound came from the computer and using the headphones was fine... now i have the computer and the TV to quiet... is there any software that you can think of that would allow me to mix the two sources on the computer?

Question about Audio line-in/optical in/Audio out/optical out

I have a late 2009 27" iMac (v3.06 GHz Intel Core 2 Duo). I note that on Apple's description of the rear ports, what I thought were simply headphone (Audio Out) and microphone (Audio In) jacks are described as:
1. Headphone/optical digital [S/PDIF] audio out:
"Line/Headphone output
"The headphone output is automatically selected for audio output if no external S/PDIF optical digital output device is detected. The headphone output supports a stereo data stream at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. The headphone output volume can be adjusted from 0.0 dB to -64 dB..."
"The headphone output is automatically selected for audio output if no external S/PDIF optical digital output device is detected. The headphone output supports a stereo data stream at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. The headphone output volume can be adjusted from 0.0 dB to -64 dB."
and
2. Audio line-in/optical in:
"Line input
"The analog line input operates independently from all other audio input ports and is always available. The line input supports recording at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. Audio recorded from the line input is presented as a stereo data stream. You can adjust the line input gain from -16 dB to +30 dB..."
"The digital audio input has the following electrical characteristics (nominal specifications), based on input of a 1 kHz sine wave at 0 dBFS input level, 24-bit sample depth, and 44.1 kHz sample rate (unless otherwise specified below):
FSI – input sample rates: 44.1 kHz, 48 kHz, or 96 kHz
Bits per sample: 16, 20, or 24
Signal-to-noise ratio (SNR): >130 dB
Total harmonic distortion + noise (THD+N): <-130 dB (0.0003%)
Sound output/digital audio output port"
While, as an Olde School audiophile guy (62, and I still have vinyl!), I generally understand the gist of all this, I'm not at all hip to what S/PDIF optical digital output and/or digital audio input can do for me. So my questions are:
1. Can somebody please wise me up to the usage(s) of these optical inputs and outputs on the iMac?
2. The Apple description says,under "Line/Headphone output":
"PCM: 16, 20, or 24 bits per sample at sample rates of 44.1 kHz, 48 kHz, or 96 kHz
AC-3: 16 bits per sample at sample rates of 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, or 192 kHz"
and under "Line input
"The analog line input operates independently from all other audio input ports and is always available. The line input supports recording at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. Audio recorded from the line input is presented as a stereo data stream. You can adjust the line input gain from -16 dB to +30 dB."
How -- where -- do I adjust these bit depth and sample rates?
Thanks for your help!

Thanks for the info. Turns out there's an even easier way to do it than using the "Audio Midi Setup": through the prefs in the latest (and probably some previous) version of VLC, which is currently Version 1.0.2 Goldeneye (Intel 64bit).
Now if we could only get full native resolution (or at least 1080p) HDMI input into the Mini-DPs of our 2560 x 1440-capable 27" iMacs and actually have it display something WAY better than 720p (half the resolution of which the 27" iMac is capable) to which Apple limited it, without having to buy a third-party $270.00 HDMI-to Mini-DPP converter and scaler. Call me crazy, but it seems kinda silly to have to pay another $300 to buy a device that will scale the 27" iMac's resolution back up to a measly 1080p, let alone its native 2560 x 1440. But, as the
As a side note, can anyone tell me -- perhaps the elusive and chimerical, but omniscient and omnipotent "communityhosts" of Apple.com -- why, in my original post in this thread, the phrase "1. Headphone/optical digital S/PDIF audio out" had the acronym "S/PDIF" stricken through, like it was a particularly egregious Anglo-Saxonism? Wikipedia defines the acronym thus: "S/PDIF is a data link layer protocol and a set of physical layer specifications for carrying digital audio signals between devices and components over either optical or electrical cable. The name stands for Sony/Philips Digital Interconnect Format."
If I have inadvertently broken another arcane, abstruse, and/or inscrutable canon of the rules (http://discussions.apple.com/help.jspa) governing what may or not be asked or said on these avowedly "user-driven" discussions, allow me to beg for forgiveness beforehand, pleading ignorance, and ask that Apple's "community hosts" or administrators would expand upon and make very clear, in their "Apple Discussions Terms of Use," a comprehensive list of terms, subjects, lines of discussion, references to certain items, products, people, policies, etc. that are simply disallowed in the forum.
It is extremely depressing and frustrating to spend however long it takes -- and it takes ME a long time, as I have a 60-year-ingrained tendency towards verbosity -- to ask and post a question or message, only to have the message never even posted to the forum, but, without any sort of consultation with me so that I may learn from, and correct, my errors, uncaringly consigned to the illimitable void by hands to whom there is no appeal or orison.
It seems unfair.

Audio Line-In Input: Not Reading Sound

So here's my problem:
I tried recording some stuff I was doing in my DAW using Quicktime's Audio Recording option. My understanding is that I simply start a new recording, choose my input device, and start recording (by which I chose "Built-In Input: Line In"). I chose that option thinking, "Oh hey, I obviously want the highest quality sound for a recording so my friends can hear what I'm doing...why not have them hear what I'm hearing in my headphones?" Turns out, after I listened back to the recording....NO SOUND. I triple checked but the audio clip had no sound...just silence. Then, I went to system preferences, checked to make sure the correct Audio Input was selected...yes: "Line In: Audio Line-in port," NOT "internal microphone." Ok...so what now?
Then I went into the AUDIO MIDI SETUP in Utilities to make sure everything was okay there. Everything's fine...except the master volume on my Built-in Input is set to "0." The left and right faders are at a moderate level but the master is simply 0 (and it won't let me adjust it...it's just grayed out). The weird thing is, when I go back to system preferences, I have the Built-In Input level turned up. Why are these two levels different if they're the same input? Is this why I'm getting no sound when trying to record things like: music coming from my DAW, or simple audio tracks on my mac, or other recordings? I should emphasize: I AM hearing sound through my output, BUT I am NOT able to record that sound with a recording device. I've tried multiple things: Line In application, Audacity, restarting comp, changing to audo interface, checking DAW settings, etc. Why is my Line-In Input getting no signal? Thanks guys!
My specs:
http://support.apple.com/kb/sp644

Couple of things to check, you say you have selected line in ok, are you sending an analog signal to the line in port?(It needs to be analog to be seen) If you are, when you open QT, under file click new audio recording, then also click the little white triangle on the upper right and make sure that it is set to line is a well. You need to click the red square to begin recording. Also check the Audio MIDI Set Up is configured as in the 2nd screen shot
