Topic: Bringing audio into an iMac

Another (stupid) question from a PC convert.

How do I bring my analogue audio signal from my stereo into my iMac so I can record, edit, and create audio CDs? I've got the hardware side down since I brought this into my PC, but I can't seem to find the right settings in GarageBand to recognize the input.

My goal to to take the saved file, throw out the parts I don't want, define new tracks, and then write this to a CD for personal use.

Thanks

Re: Bringing audio into an iMac

Which model iMac is it?
Does it have an audio line input jack? Not all do.

In System Preferences, Sound, Input, select the Line In.
In GarageBand, under Preferences, under Audio/MIDI, select the Built-In Input (or System Setting after the above step).

If you don't have an audio input jack, you can get the Griffin iMic, a USB audio input device.  Support both line-level and mic-level in and out.  We sell them at my store.

GarageBand is a full music authoring program.
If all you want is to record audio, I use the aptly named "Audio Recorder"  http://files.me.com/benshan/e9dovg
and then the free "Audacity" for editing.   http://audacity.sourceforge.net/

Re: Bringing audio into an iMac

This is the latest Intel iMac with the 21.5" screen, 4 MB of RAM, and a 1 TB drive.

OOPS. I was all set to answer your next question when I decided to go get a flashlight and make sure I was seeing the icon correctly. What I thought was an audio input is a headset output. Guess that would explain a lot! Your remaining suggestions should take care of me. The biggest one is the Griffin iMic, a USB audio input device.

Thanks a lot Steve- this should resolve my question.

Re: Bringing audio into an iMac

The new iMac has both an analog and digital in and out.

The left most (when looking at the rear) is the output jack (with a headphone icon), and the 2nd from left is the line input jack (with in input icon).

Re: Bringing audio into an iMac

How right you are Steve. I must be overdue for my eye appointment. I actually had my audio jack plugged in there, but was not able to figure out the right settings for Garageband to bring the audio into the system. I downloaded Audio Recorder and that is working fine.

I'll need to play some on the editing side, but I've downloaded per your recommendation and I should be on my way.   Thank you for your patience.

Relevant to this topic:

I remember someone doing a presentation at a Cider meeting a year or two ago about transcribing from LP or Tape to a CD?

I think the powerpoint charts were posted with the meeting notes. Are they still there someplace?

Re: Bringing audio into an iMac

As I gradually work through my challenges, I'm back to audio.

kcupery: I glanced in the archives and it looks like it may be a long and lonely search. Do you know if there is a search engine to pull up the appropriate meeting information?

Steve: I downloaded audio Recorder 3.2. While very basic, it appeared to get the recording part of the job done, thus creating an .m4a file. However, Audacity doesn't appear to be able to read that file. When I try to open the file in the Audacity dialog box, it is grayed out so I can't select it for editing. The music plays when I select the file, and I can open it in iTunes. However, I still haven't figured out how to open yet. [Garageband doesn't want to open the file either.]

I did play with Garageband some trying to learn it. After working with it awhile, it said it was stopping because it has reached the maximum file size allowed at 2GB. However, when I look in the GarageBand folder in the music folder, the only files there are a few MB. Any idea where the 2 GB files was getting stored.

Ah, such an opportunity for learning.

Re: Bringing audio into an iMac

Audacity may not do AAC.  Save as MP3 or AIF.
Audacity will also record in itself.
I use Audio Recorder because it's such a simple UI it doesn't get in the way during other uses.


The presentation "Digitize your Vinyl" was in August 2005.
Some of the older files were removed for space. Since Apple raised the iDisk to 20 GB i've started to put them back.

Re: Bringing audio into an iMac

Steve: At our last meeting, I noted that you have your Audio Recorder to save files as .mp3. However, the version of Audio Recorder I have is encoding as .mp4. The directions speak to downloading LAME, but my search for that brings up a long list of options. The ones I have tried so far do not enable that recording option.

Can you give me some hints on how to add this functionality to my Audio Recorder?

Thanks

Re: Bringing audio into an iMac

Google LAME and you'll find several locations to download it from.
The Audacity page has links and instructions too.
http://audacity.sourceforge.net/help/fa … i=lame-mp3

iTunes will convert to MP3 without needing the LAMElib, it's already built in.

Re: Bringing audio into an iMac

Pretty much following the advice and suggestions here, I’ve embarked on a little project of transferring a few old cassette tapes to audio CDs. It’s worked pretty well and I thought I might as well report my experience.

I bought a cable with two RCA audio plugs at one end and a 1/8" (3.5 mm) stereo-mini plug at the other end. This connects a tape deck to my iMac.

“Audio Recorder”, as suggested by Steve Rea, works just great! It is simple, easy to use, and produces a single WAV file from the tape. I first ran parts of the tape to set the level and then did a complete recording of both sides of the tape.

On to Steve’s other choice. I found Audacity a little less intuitively obvious  to use, but there is an Audacity Wiki site that has some helpful information. (http://wiki.audacityteam.org/wiki/Main_Page)  Audacitys chief  attraction is that it is free & gets the job done, even if it seems a little buggy at times. I found it helpful to keep all files for each project in a unique file or sub-files.

Audacity can import the WAV file that Audio Recorder produced and separate it into tracks, applying a title to each (with the name of the song, for example). Audacity also lets you cut and paste, delete, process for noise and a bunch of other classy things, but these really need to be done before you designate the tracks, as the markers currently do not “stick” with the audio but with a separate marker track.

After marking the tracks you can then “export multiple” from Audacity as WAV files. This yields a separate WAV file for each track with each file labeled with the track name. (If you choose the right options).

I then dragged these files onto a new and appropriately titled playlist in iTunes. (You might want to check the import preferences for iTunes first).

Finally I used the burn disk function in iTunes to produce an audio CD!

It seems like a complex process when described, but it works pretty cleanly. Most time is spent playing the tape while recording the initial file.

The icing on the cake is that iTunes will print out a very classy little CD jewel box liner from the print options.  You can even make up a template for the back and edge liner (if you’re using the thick CD cases).  I scanned the art from the tape liner and printed it on the iTunes printout. If you didn’t care about copyright piracy you could almost sell these at the public market on Saturdays!

Now on to old LPs!
