It’s time to dust off those old CD binders.
Nah man. If you care about your CDs you should already have them ripped to flac format, so the disc rot can’t kill them. Convert to mp3 vbr0 for tossing them on a player or your phone. Listen with whatever ear buds you like.
It’s not like vinyl or casette tape, where the analog nature of the storage medium is going to effect the sound. CDs are pure digital, just a carrying case for the files on them.
Or buy your music from a source that offers both. I have flacs from bandcamp, but also CDs from those same albums
kobuz baby
That’s the first thing I did with all my Frank Zappa cds… converted them to digital and put the cds away so they wouldn’t end up scratched.
I agree about ripping the CDs to files, but disc rot is not a big deal to worry about if you’re storing the CDs properly away from sunlight and heat. Recently I’ve been going through my collection and ripping old CDs of stuff I didn’t have in the digital library… and all my CDs from the 90s that I’ve tried are still good. Many of these are 30+ years old and still sound perfect
Flac or wav, right? Is flac smaller?
Or go 320kbps mp3…
wav is uncompressed PCM usually, flac is compressed and as such smaller (difference in size depending on the kind of music), but they’re both lossless with the resulting signal being bit for bit identical to the data on the CD.
320 kbps MP3 makes little sense nowadays except for when you need maximum quality for a device supporting nothing else. For long term storage, use flac.
There’s still some use cases for sure. My 4 gig Garmin running watch (2.5 usable) might play flac but I want more than a few albums on it.
Then again why would it need to be at 320 kbit for this kind of use case
There’s no technical reason for 320 CBR but the space loss from a VBR ~224 encode to the CBR 320 is minimal compared to 320 vs flac around 1000. I do keep two copies of my collection for space reasons though - one in flac and one at 320. My phone is still a limiting factor to from a space perspective, I can’t store my entire collection on it in flac but I do choose to use it where I’m actively listening to an album through the weeks. The rest can be mp3 because it’s usually a single song that gets in my head.
I don’t really have MP3-only use cases anymore, but back when I did, it was mostly where transparency was achieved rather easily, like listening to music on the go with… non-perfect headphones, and on those cases, I went with lame’s -V5 IIRC which is closer to 130 kbit/s or so. For higher quality, but not lossless (storage was still expensive back then) I used Musepack. But high bitrate MP3 was almost never needed.
It is my understanding that FLAC is effectively a zipped WAV file. Same audio but with lossless compression.
Is flac even necessary if they are coming off CDs? A CD is most often 192kbps mp3 format.
Ripping to flac is like ripping a 720p video to 4k and just filling in the extra resolution with black bars.
Edit: this is incorrect. See Captain Aggravated’s comment below.

This is not correct, with the caveat that you can burn a 192kbps mp3 file onto a CD-R if you want, I’ve done it a lot in my younger days.
When you buy an album on CD from the store, that disc will almost certainly have a mark on the label that says Compact Disc Digital Audio. Which means it conforms to the so-called “Red Book” standard which defines its own data format, which consists of uncompressed, 2-channel, PCM audio sampled at 44,100Hz. This works out to be 1,411kbps. WAV files are much more similar to CD digital audio than mp3 files are, and a 16-bit 44,100 Hz WAV file has basically identical sound quality to a CD.
mp3 uses a lossy compression algorithm that allows an mp3 file to be a tenth the size of a CD-quality WAV file at the expense of audio quality. With more modern encoders and selecting a higher bitrate like 320kbps or so you can get pretty good mp3 files but they will not match a CD. There were some cd ripping software packages that would describe 192 or even 128kbps mp3 files as “CD quality” which is demonstrably incorrect but probably the source of this misconception. If you were to repeatedly rip CD audio to mp3, then burn an audio CD from that mp3, then rip the copied disc to mp3, the audio quality would degrade with each iteration.
FLAC uses a lossless compression algorithm and can achieve similar results to ripping a CD to WAV format, but at smaller file sizes than WAV. it won’t be as small as an mp3 but it won’t suffer from audible compression artifacts. Rip a CD to FLAC format, then burn a new CD from that FLAC recording, and it might not result in a bitwise identical CD because I bet the gaps between tracks wouldn’t be perfect but take any random 10 seconds from a track and they should be identical. Repeatedly rip to FLAC and burn to disc and the audio quality won’t degrade.
It’s theoretically possible to encode higher quality audio than that but you start hitting the limits of human hearing at that point. Also CD audio is strictly stereo; the earliest versions of the standard briefly mentioned quadraphonic audio but this never made it to production, and it can’t even do mono. CDs with monaural audio on them are stereo with identical left and right tracks. I personally wish they had included a mono mode in the red book standard so you could have audio books with 2.5 hours on a single disc, but that’s what I get for wishing I think. Whatever we have downloadable files now.
But to answer your actual question,* FLAC isn’t necessary. mp3 files are capable of sounding pretty good at smaller file sizes than FLAC. Because the devices I own that I use to listen to music all have 256GB of file storage or greater, I am personally not as concerned about file size as I used to be so when I do buy CDs I rip them to FLAC and listen to them in that format, and the audio quality is better than the 128kbps mp3s I was perfectly happy with as a teenager.
Thanks for the info and detailed response!
I was aware of mp3 being lossy and flac being lossless, but I had thought that CDs used a lossy format of some kind. Which was apparently wrong. I’ll look more into it.
Alec at Technology Connections did a good series of videos on Youtube about it, and he’s always a hoot.
There is an argument made mostly by the “vinyl is best” audiophile crowd that ALL digital audio is lossy because of an upshot of the Nyquist-Shannon sampling theorem, a key principle in how digital audio works. In order to avoid distortion due to aliasing, the sample rate of a digital recording must be at least twice the bandwidth of the signal. There’s a problem where if the frequency of the audio is way higher than the sample rate, it could produce the same series of samples that a lower frequency sound might, so it might play back incorrectly.
In practice, this means any audio that is digitized must be band-pass filtered before sampling. We tend to recognize the range of human hearing to be from about 20 Hz to about 20,000 Hz, so digital audio is low pass filtered to remove any sound above 20,000 Hz before being recorded. A sample rate of 44,100 Hz is a little more than twice that maximum bandwidth to allow for some wiggle room. There are people who claim they can hear sounds above 20,000 Hz, but they had to draw the line somewhere.
A practical upshot of this is you can’t record an ultrasonic dog whistle to a CD; even if the microphone could pick it up it would be filtered out before sampling. But, when taking practical constraints such as the biological limits of human hearing and the inertia of the speaker cones into consideration, CD audio can perfectly replicate any sound humans can hear in 2-channel stereo, which is why it hasn’t really been improved on in terms of sound quality in 40 years.
Compression, whether lossless or lossy, is a whole other can of worms that red book audio has nothing to do with. It’s amazing they were able to produce consumer-grade electronics that could decode that amount of raw data in real time in 1980, especially given the robust error correction it has built in. The processing power required to decompress audio before decoding it just wasn’t available while the Red Book was being written, so they didn’t include compression in the standard.
We treat CDs as obsolete here in the Spotify era but they’re still technological marvels.
Commentary: I would expect someone familiar with Technology Connections to ideally call it a Hoot for sure.
This is one of those “they were so concerned with if they could do it, they didn’t stop to think if they should” sort of things.
Portable cd players were never actually that portable, because cds are just big. Minidisc players sure, but those never really caught on. MP3 players, however, caught on because they are small and easily portable, and the library doesn’t take up a binder.
Also portable CD players skipped constantly. Minidisc was way better for that, but then MP3 (and Limewire) hit…
With current technology you could make them a lot better. Basically put 700mb of flash memory on the player and rip the whole thing as soon as you put the CD in, then play from flash. But then you get back to why you would want to do something like that again.
That was basically how anti-skip worked, albeit with much less memory.
They would buffer the audio for like 10 seconds that way.
Heck yeah!
I had a Sony atrak 3+ player back in the day (around 2003-4, probably, because I used it at work) which was just an mp3 file compression alternative served up on a special cd player instead of an mp3 player… they tried… anyway I had a re-writable disc that I’d add stuff to whenever I downloaded it, and I think the one cd had like 1800 songs on it or so (and lots of space left)
That didn’t skip, even working a physical job, unless I banged it against something. Part of why I got it. But when I put regular discs in, they would skip a lot if I didn’t have it laying flat.
I loved my MiniDisc player, I wish Sony had opened up the tech.
.
No they aren’t
They are.
Now we just need to wait for the CD to come back.
This may sound crazy, but hear me out. What if instead of a spinning plastic disc we use a spinning metal one, for durability and to reduce movement of the medium while accessing data. It would also allow for much greater storage density if we stack a bunch of them.
But fuck the laser, we’re gonna go back to the record-style reader head
HDD?
Bingo
why
It’s not a bad idea if you have a good library, but $180 is crazy
It’s got a balanced headphone output, so they are obviously targeting the audiophile market.
I don’t know why anyone would want to use a portable CD player though. They scratch up your discs and skip if you move around too much.
What would a balanced output do for the 3 feet of cable that will most likely be connected to it? I mean sure, put it in if you can’t help it, but even though it’s a portable player, no one is gonna take that to the next motor fab where it would benefit from a balanced output, and at home an audiophile most likely already has a better player around.
And yes you’re right - the whole idea is nonsense to begin with. CDs have always been fully digital, so better listening options exist.
A balanced output will have less crosstalk between the channels. I’ve never used balanced headphones, so I don’t know if it’s noticeable. My guess is the only really noticeable thing is that the higher output voltage swing from the differential amplifiers will make high impedance headphones louder.
I have a bunch of audio equipment in a studio and do run some balanced lines to stuff that requires longer cable lengths that are in proximity of unrelated, noisy devices (e. g. digital stuff).
Can’t say I can tell any difference for headphones.
Why not just rip your CDs and play them on a DAP?
Why would anyone want this
portable players where always trash, this looks like some audiophile wankery that is only ever used stationary … and I still have a real cd player for that.
Yeah sure. Also, Milli Vanilli are back…
Pulled from the grave, just like portable CD players?
(Boo! OK, I’ll see myself out. MV is a tragic story)
I suspect it’ll be quite popular in Japan. There is still a huge CD scene there.
Cool, can’t wait to go running with one.
Man, I feel so old… knowing I once had wired earbuds with a portable DVD player.
I still have my binder, however I’m a much different person now and don’t listen to same music as I did when I was younger. I’m ashamed to admit it’s half full of red dirt country. Luckily the other half is 90s metal and rock
Who asked for this?
