Hi all,
I need some advice, I need to convert some talks at my local group
from
tape to CD. I have a mike input on my audio card so connecting the
audio
should not be a problem.
I believe that the mic input is handled differently than the line
input (automatic gain control, decibel boosts, etc.). Use your
card's line input jack instead. It should be right next to the mic
jack. In most color schemes, it's usually the blue one (red=mic,
green=out); read the labels if you're not sure.
What file formats do standard CD players play ? I would guess mp3 but
there do not appear to be any mp3 encoders for linux, ogg would be
great
but I doubt that it would play.
Standard CD players play waveform audio (WAV), but I believe it needs
to be aligned to the CD block boundaries. However, you'll need to
burn it as an audio CD, not a data CD, otherwise it will be
unreadable to the CD player. Most CD players nowadays can play back
MP3 data CD's but there's no standard, not even a de facto one, for
this.
Dare I say it? Most people do have computers, so if your local group
doesn't make "Learn [subject] While Driving" tapes, it may be cheaper
and easier to simply forgo the physical medium and stick them on a
web server for downloading/streaming/podcasting. MP3's of people
talking don't require the higher bitrates that music does, so you can
drop the bitrate and change it to mono (one-channel audio) to save
some server space/bandwidth.
Can anyone suggest an application to get the files from the tape &
change them into said format ? (Simple is good, I dont need a
recording
studio :))
Anything that can listen to your card's line-in will do. I haven't
done it on Linux, but on Windows/Mac OS X, pretty much any program
will do it. As for burning, most programs that can burn an audio CD
take MP3/WAV/OGG/WMA/AAC files (your choices may vary depending on
the app) as input and do the conversion themselves behind the scenes
before burning.
