DbPoweramp and EAC are the best. Both have error correction and cross reference the digitized data on your (digital file ripped cd) to other cd's. If the cd you currently use is trying to rip, but has even one or two scratches (or is even flawless, but your laser on your reader misses some data, EAC will know it, and will actually fill in that line of code that was missing!), no worries; EAC / DbPoweramp will fill in all lost data on your cd's. It's really quite a fascinating process as you're watching what tracks are bad on a cd even if the cd looks pretty flawless. If the laser (reader) doesn't pick it up, both EAC and DbPoweramp will accomodate for your lost data. =-) Voila! Perfect digital file! With every single byte accounted for. By cross referencing your cd to others cd's.
Both are free. I think EAC is naturally free.
This is the main feature over Foobar. EAC/DbPa also maintain the ability to very easily convert files (ALAC > FLAC > AIFF), and rip each file with differing levels of compression! 1-8. 5 is the default.
There are other advantages as well, but these are the two I love the most. Everything ripped using these two programs is more accurate because your data is cross referenced to others data. This is not a global program and only those who download (Audiophiles who use the programs) can cross reference with one another as well, it's a very grassroots program. Which I like. ;) Basically, imagine the advantage Kernal streaming gives for free! Using EAC or DbPa yields the exact same results/benefit to your digital file as Kernal stream does to playing your file: (much better sound) as opposed to ripping strait Lossless without Error correction and running it through the windows mixer. You also lose out on the ability to play with different compression ratios (i.e less G/B space, this is important in the Dx100 if you want to fit the best of that 2.7TB collection on there). In tandem, they account for much purer sound and cleaner music. In tandem, I really, really enjoy listening to music ripped either by DbPoweramp or EAC properly. This is the same software high res. download sites use as a base. It's good software!
Most use EAC. It's easier to use. Both yield the same result.
