What you want to do to become an expert is go to HydrogenAudio (dot) Com and prepare to do a LOT of reading. As long as you don’t pirate music, (they destest that over there) you’ll get a lot of help.
Basic fact:
Lossless - No loss in music quality
Lossy - Some music is lost.
If you’re going to re-rip a CD, you might want to invest in an external hard drive and rip all your CDs to lossless. You can get a 1tb external for about $100.
The formats are called codecs, that means COmpression and DECompression. Get it ![:slight_smile: :slight_smile:](https://emoji.discourse-cdn.com/twitter/slight_smile.png?v=12)
The big “Three” lossless formats are FLAC, WavPack and APE. ALAC is from Apple (used with iTunes and iPod) and is also lossless. So which one is better. None. Lossless is lossless it’s all the same. The difference comes in the compression and decompression rates. WavPack is the best for both. APE compresses better but takes longer to decompress. (See Hydrogenaudio for complete details). If you share files, FLAC is the standard
Lossy music means you are losing some quality for the sake of space. For instance a WavPack or Ape or FLAC file compressed the original CD track to 45% to 60% of it’s original size. A lossy format compress it to about 15% of the original size.
The “Big three” lossy formats are mp3, aac (mp4 or m4a <-they’re all the same) and WMA.
Note: WMA produces a lossy codec and also a lossless format. BOTH use the file extension wma. The only way to tell is if you look at the file size.
So which is best? They all are excellent. Lossy formats don’t depend on the codec as much as the compression rate
If you share files, mp3 is the most accepted. You’d be hard pressed to find a player that doesn’t support mp3. WMA is the 2nd most popular lossy codec. AAC (mp4, m4a) is also widespead but not as big as the other two
If you go to hydrogenaudio they have a section that compares the lossy codecs for audio quality. For instance aac(mp4) is better at compression than mp3 so you can use a lower bit rate and get similar results.
For simplification I’ll use mp3 bitrates.
There are three basic type of bit rates. Constant bit rates (CBR), Variable Bit Rates (VBR) and Average Bit Rate (ABR). CBR gives you a bit rate that is the same throughout the song. ABR gives you different bit rates though the song but at the end the average of all the bit rates used in that compression of that particular song is what you specify. VBR shoots for a bit rate you specify, but isn’t tied to it.
For instance in VBR if you want 192 if a part of a song uses less, it won’t go that high and if parts of a song uses more it’ll go higher. Thus if you specify 192 you may get a final of 200kbps. Because the song needed more. With an ABR of 192 you get a final of 192kbps.
VBR is considered the best compromise between space and quality.
At about 192kbps most people cannot tell the difference between an mp3 and a CD. 320kbps is virtual CD quality. 128kbps is considered the least acceptable rate.
Now remember that a few things to consider. Bit rate also depends on the TYPE of music. A heavy metal song uses high bit rates to get quality. On your average pop/rock song you probably wouldn’t notice at 192kbps. But for a heavy metal or classical song, you’d most likely still notice the difference at 192kbps
It depends on the TYPE of music too.
So what’s the best bit rate. NONE. It’s all up to your ear. For me 192kbps using a VBR is indistinguishable from a CD. But this is just me and most of my songs are pop/rock music.
Your bit rate of 64kbps is really the top of the line for SPOKEN tracks. Remember you can go as low as 16kbps for SPOKEN records.
But that’s not all. It’s not only the codec you use but the MAKER of the codec. For instance, not all mp3 codecs are the same. The best mp3 codec is made by LAME. The best aac (mp4, m4a) codec is made by Nero, (iTunes comes in a close second)
So go to hydrogenaudio and look around and you can look at their listening test of the codecs and decide for yourself.
Finally you need to rerip your CDs. EAC (Exact Audio Copy) is the best ripper and get this, it’s free). EAC is a bit more complex than most rippers. It takes about 20 to 30 minutes for newbie to set up. Hydrogenaudio has an excellent guide so you can set it up correctly.
If EAC is just too much try the CD Ripper from DBPoweramp. This is considered almost as good, (but not quite, although some people aruge DBPoweramp’s ripper is as good) as EAC. The thing is DBPoweramp charges for it’s software. DBpoweramp also converts formats with ease. Just right click on the file and convert.
CDEx is another CD ripper that is good but not as good as EAC or DBPoweramp (see tests at Hydrogenaudio for comparisons)
What I did was rip all my CDs to my computer in WavPack (Lossless). Then I use DBPoweramp to convert them to mp4. Then I put those mp4 tracks on my iPod. Then I delete the mp4 files and I still have the lossless tracks.
Again, look around Hyrdrogen Audio. They are very helpful unless your a music pirate. They don’t tolerate that on those forums. But if you ask questions they are very helpful and respectful. The only thing they hate is music piracy. So if you are a pirate of music, don’t mention it ![:smiley: :smiley:](https://emoji.discourse-cdn.com/twitter/smiley.png?v=12)
