Re: an interface for configuration of a lowpass filter?

If your ripping primarily for portable music players, the ability to run it through an AudioUnit that would cross-mix the audio a touch would be nice. Many headphone amps do this, mixing a bit of the right channel into the left ear, and vice versa. This is to more accurately produce the sound the ea...

Are the G5s dual core? If so, this would explain it, as while multiple encoders can execute at a time, if only one track is being encoded, it only uses one thread, which maxes out only one core.

The wikipedia article pretty much nails the explanation of SACDs and the hybrid discs. BTW, I have the <i>Dark Side of the Moon</i> SACD (hybrid), and you can definitely hear a difference between the two layers on my (modest) equipment: - Denon 1920 CD/DVD/DVD-A/SACD player - Marantz SR5500 - Polk M...

SACD is a very different format than DVD-A and Redbook. SACD isn't PCM, but is DSD (or DSS, I forget which acronym). The input audio is sampled at ~2MHz, and is encoded as a 1 or a 0 if higher or lower than the previous level sampled. So it's just a continuous stream of 1s/0s saying higher/lower. No...

I like Max, but if not Max, then Halcyone.

I probably won't be able to get it packaged up until tonight. I had other stuff going on last night, and today well, I need to work. :) I'm going to roll it into a class instead of the loose functions so that I can fix one last nagging bug. Will take maybe an hour, once I sit down to actually do it.

Yes, that was me asking about the FUA bit on the Darwin lists ( http://lists.apple.com/archives/darwin-dev/2006/Jan/msg00086.html ). I also filed a bug report/feature request for FUA (Apple bug number 4424205) but for some reason their radar won't let me view the bug anymore. I figured so. I like t...

So, I reworked my code a bit, and simplified things by reading 4MB blocks, and just reading the 4MB block twice in a row. Since it's big enough, it just forgets the first half of the read, and everything on the second read doesn't come out of the disk. At least, the same cd showed the same bad 5-6 s...

I like your approach to reading a batch of sectors at a time vs. the whole track- it saves both time and memory (but mostly time)! It seems like an efficient approach, as well. Thanks, it seemed like a much easier approach to it, the only rub is doing it in a large enough block to ensure that you'v...

I took your idea, and your port of paranoia that's in the Max code, and banged on it some yesterday afternoon. I was able to get something working with a "known bad" disc. Instead of reading the whole track multiple times until it turned out to get some sort of statistical certainty to the accuracy ...

{Edited} Ok, so I've been doing some serious digging on the 'net, and started running some tests. Tiger "broke" paranoia. I've had a customized version of paranoia for a while, and it was merilly rejecting heavily scratched discs. I just grabbed a few of those, and ripped them twice, and md5'd each ...

So, what's wrong with using paranoia? It seems to work nicely, and I've used a different port (I think different) that clearly was able to not use the cache, as it routinely ran into disks of mine that it found issues with, and was able to deal or not deal with the issues based on the depth of the s...
