Recording Audio from speaker-out to mic-input loop - does this work?

[tankman1989]

I am trying to figure out how to record audio from my computer by using the speaker output being piped directly into the microphone input. Is this possible? I am using a standard mini-jack that is male on both ends. I don't see why this wouldn't work, but I may be ignorant of how microphones work. I may need to turn down the output level of the speaker and/or the input level of the mic. I would like to us Audacity if that is possible.

The reason for this is that I have a number of M4a files that are 11+ hours long and are difficult through which to navigate. I also can not play these files on my Zen MP3 player.

I have tried converting these files with a couple conversion programs but they all stall around 29.5%.

I also would like to increase playback speed by 50% and decrease pitch by 33%, which makes the narrator sound the same (in pitch/tone) but i can listen to 90 mins in 60!

Any suggestions?

Sounds like the program you're using right now is loading the entire file into memory instead of a less intensive method of processing data. The only application that I can think of that can do all of this with ease is Celemony Melodyne Editorp

You can take your audio and bring it to an indecipherable fast or slow point but keep it in the same pitch, key and noise level.

I hate to suggest this, but if your methods of conversion aren't working you should be able to burn the M4a to CD then use a program like Itunes or Audiograbberto rip it to Wav or mp3. However, that sounds like torture to me!

how do I do that with a 11 hour mp4?

why not just record them using Audacity save all the messing around with cables and will let you do the editing you require.


them again 11 hours will be a long boring recording session unless you leave it running and go back once all recorded.

Thank you for the suggestion.
It should be no problem to load the file into memory. I have 8Gb and the m4a is 290mb.

I don't understand what you mean. I have the M4a files, (5 11 hour files, 290mb each). I want to convert them to MP3. I can not get audacity to load the m4a files, as it just loads some screeching mess that is only 20-30 seconds long.

Could this be a DRM issue?

possibly will be a drm issue.

norm when i use Audacity i just play back in my normal playback application and set Audacity to record from the soundcard in stereomix

You could record it to a DVD.

You could record it to a DVD.

I am a little confused. Do you mean record it as a data file or as an audio file? I didn't know you could record audio on a DVD in a non data format, or maybe I'm missing something.

Thanks.
