Audacity

Archived from groups: rec.audio.pro (More info?)

I have been playing around a little but with Audacity on Mac OSX, after
looking for something to recommend for simple 2-track editing, and as best
as I can figure out, it seems to have some serious problems. I'm trying to
figure out if the issues are on my side or not.

If I rip a CD from within Audacity, it calls itunes to do the actual work,
and there is a substantial probability of there being loud bursts of digital
noise in the transfer. Uusually I can see them on the waveform display, and
usually if I rip two or three times I can get a clean transfer.

BUT, sometimes in the editing process, loud bursts of digital noise seem
to appear in the file. Sometimes what look like noise appears on the
waveform display, but if I zoom in and then zoom back out it disappears.

Sometimes I will have a clean file that appears to play properly. But then
I export it as a .wav file, and I get a file with loud bursts of noise in it.

I am running Audacity 1.2.3 from the Nov 13 build. Has anyone else seen
this sort of thing? It's enough that I would consider the thing basically
unusable. It's being run on a G5 with some insanely large amount of memory.
Considering that I have done reliable 2-track editing on a 68k mac and had
no problem, I can't imagine it's a lack of system resources....

I am using Spark XL from TC Electronics.It works pretty good and is quite
easy to use under OSX

Too bad they started making it out of unobtanium.

That's curious, because I recently set up a music teacher with an
AluBook, OSX, Edirol UA-25, and Audacity. She has now burned a few dozen
CD's for her students without any of the noise about which you're
talking, using the same approach: save the Audacity files, which are in
its own format, out to a format iTunes recognizes, drag 'n' drop, and
burn.

Looks like the Mac version of Samplitude...

If you check out the background of the main guy programming DSP Quattro
you might see that there is potential in the app that Peak isn't going
to get, ever. Then compare pricing, and note that the recent upgrade
price for DSP Quattro was something like twenty bucks. I think those i3
guys are onto something, and we're just seeing the early stages of their
efforts.

There's a setting in iTunes that will retry when errors are detected instead of
just going on. I have never seen a noise burst with iTunes itself, although I
don't rip stuff if I'm serious about it, I record it in S/PDIF instead.

Itunes - preference - audio

This also turned out to be a major issue. Why isn't this enabled by default?

where they have their own mp4 aac data compression ......ipod with
higher quality sound then mp3

No, the burning procedure seems to be fine, actually. The problems have
all been getting the data into Audacity, and getting it to stay there
uncorrupted.

Good news (mostly.)

Try installing portage for OS X, which will give you access to most of the open source world. Imagine Berkeley ports on steroids <http://www.gentoo.org/doc/en/macos-guide.xml> <http://gentoo-wiki.com/Gentoo_MacOS>
