Hey everyone. I'm pretty new to the trading scene, and for awhile I've just been downloading from etree and here occasionally, leaving my windows open, and have been content with that. I've tried to reseed a few shows but had to work out some kinks each time and never have gotten one actually seeded.

Anyway, I came across a torrent today that was clearly too fast - the backing vocals were borderline chipmunks. I got Audacity and corrected the speed, and now I need to retrack it (a couple areas were cut at incorrect spots). This was pretty exciting, because it was clear how my work was paying off as I was doing the work. However, I can't use EAC since I have a Mac.

Long story, I know, but basically I really would like to be able to seed this speed-corrected version. Only two sources exist of this show - one is of unknown lineage and the other is too fast.

What software should I use to retrack the show for a Mac?

I *think* Audacity would work for you. Here's a link to the website: http://audacity.sourceforge.net/download/mac

you can use Audacity to split tracks...here's a quick tutorial:

Simplest method using Audacity and xACT:

1. Open your wave, Edit->Move Cursor...->Track Start and hit command-B.
2. Locate all your track splits and mark each one by hitting command-B.
3. Go to File->Export Multiple, select WAV as the export format, Split files based on:Labels, Name files:Numbering consecutively, hit Export.

You'll now have a nice set of consecutively numbered split tracks but they are not cut on sector boundaries. Fear not.

4. Open xACT and go to its fix SBE tab.
5. Add your freshly split WAV's, making extra sure that they appear in the correct order. Ignore the MD5 options, select your output format of choice and hit the Fix button.
6. Admire your handiwork.

Yeah, that's one thing if you do a speed correction, the trackmarkers move. Btw. - you did have it all as one audio file? Not each track loaded up as a separate .wav, because that sometime can give other speed issues.

also there used to be a snap to cdda sectors setting which I can't find anymore on the new version. that would allow you to split the wav properly without any SBEs directly to FLAC. where did it go? lol

i noticed that as well, so i've been using an older version for the time being



itsnahtatumahh -- just a fwiw, but if you end up doing a lot of speed correction projects, i'd recommend a program that'll allow you to adjust speed using key framing, allowing for variable/minute adjustments...i've used Ableton Live for the task and its excellent

Nice to see my little tutorial making an appearance but I would add one caveat with regard to speed adjustment with Audacity

----------------------------------------------
I am *not* qualified to give an informed decision on how this would affect real world application
-----------------------------------------------

In Audacity, go to Generate->Tone and, well, generate a tone. I think the default frequency is 440Hz sine wave. Select a portion of that wave and go Analyze->Plot Spectrum:

Now go Select All->Effect->Change Speed and bump it up, say 1%. Analyze->Plot Spectrum on the altered wave and you get:

The extra spikes are pretty obvious. I remember once trying this same test but performing the speed adjustment with Amadeus and Sound Studio (Mac apps BTW) and, IIRC, the spikes were even worse with Amadeus but Sound Studio produced an image exactly analogous with the original. Since then I've always used Audacity to work out how much adjustment was necessary as I prefer it as a program to work with but always performed the final adjustment itself with Sound Studio. As I stressed above, I have no idea if this effect is replicated but not as readily visible with real music but I thought I ought to at least mention my findings.

Apologies for the split infinitive in the final sentence above...damn you, ten minute editing rule !
