A block of milled plexiglass filled with ball bearings? What's the pseudoscientific rationale behind this poo poo?
Ummm.. Obviously it is specifically tuned to the resonant frequency of the Mac Mini, causing reduced listener fatigue from better harmonic coherency; greater definition with more organic tone, texture, and timbre; increased articulation with more micro-detail and micro-dynamics; a deeper and wider soundstage with increased separation and air; and better musical flow with more natural leading edge and sustain.

The funny thing about this is that since tapes are analog, they automatically get higher respect than MP3s among a large swath of audiophiles. Never mind the fact that cassette tapes have no more than 6 or 7 bits worth of "resolution" in them on a good day, utilizing the best playback equipment. If you actually tried to carry out this troll, there's a good chance the dealer wouldn't even bat an eye.

Oh, a wav is a wav, but the problem is repeatedly stressing the bits every time you decompress the RAR. Each decompression includes multiple bit-shifts and addition operations, each taking its toll on the integrity of the bitstream. If you are listening to the track even a few times a week, it will only take 3-4 months before the effects add up and the bits are reduced to shell-shocked, used-up husks of their former selves. The RAR format simply wasn't designed for repeated listening.

After laughing over the pono and doing more reading, can someone help me understand how you rate an audio format's dynamic range? For instance, according to this image 16-bit 44.1 kHz has a Dynamic Range of 96dB. But I thought dynamic range was just the measurement of someone's ability to detect audio. And since you can amplify sound and music files, how does a dynamic range even exist? I am just really confused by the idea of Dynamic Range, even after sifting through the whole wiki.

Also, I am assuming that in PCM audio the bit depth determines the frequency range, correct?

beaten but,

The dynamic range is a ratio of the difference in magnitude between the largest signal and smallest signal. In a detector, that ratio is between the biggest thing it can detect and the smallest. In digital audio, it is the ratio between the biggest signal that can be represented by the format and the smallest.

For binary integers, 8-bit can have 255 non-zero values, 16-bit can have 65535 values, a 24-bit signal 16.7 million. So the ratio of the biggest to smallest value in 16-bit is 65535:1. You can find the dynamic range in dB by 20*log10(2^bitdepth-1). More bits means a larger dynamic range.

The sampling frequency is what determines the frequency range. Part of making a signal digital is taking a reading every so often. This is called sampling. Because the data is sampled, there is a limit to what we can accurately represent. There is a sampling theorem that says that you need to sample twice as fast as the fastest frequency you are interested in. So, if you sample at 44.1kHz, you could represent, at best, a 22.05kHz signal accurately.

I just want to make sure I understand this by explaining it in laymans terms.

The bit depth determines the number of intensity intervals, or that is to say, a higher bit depth means there can be a greater difference between the quietest something can be loudest it can be.
Yes, the bit-depth also influences how small a difference there can be between two things of almost the same intensity.

quote:

The sampling frequency determines the range of frequencies a sound file can output. So a sampling frequency of 400 Hz will create a sound file that can only output 200 Hz max, or that is to say, very low tones.

And because human hearing upper limit is around 20kHz, anything above a samplying rate of 40kHz is essentially pointless correct?
Right. I don't think anyone disputes the sampling theory. The counter-claim is that sounds above 20kHz influence our sensing of the audio even though we have a difficult time picking out those frequencies in a hearing test environment. I'm skeptical, but the only downsides to a faster sampling rate are increased processing overhead and larger filesize. Which are almost free these days, so go for it IMO.

quote:

Also was the dynamic range expressed in dB for the express purpose of being used in conjunction with reference volume?

dB is a good way to express a ratio that can be very large, so it gets used for a lot of things. This wikipedia page has a whole bunch

This is not true. Sounds over 22khz played through many systems can cause audible aliasing or harmonics (which are bad).

Yeah, I suppose so and maybe even likely on an average setup. I meant more 'it isn't worse as a technology', and didn't mean to imply that it would always be better in practice. I can see how what I wrote could easily be taken that way.

Do audiophiles sperg about ECC memory? Seems perfect for them: it protects against mysterious cosmic rays, the errors protected against are very rare and hard to identify, and it costs a bunch of money versus the typical solution.

There are lots of procurement issues with fancy screens if you aren't a huge buyer, usually you can only get the left overs with no guarantee of being able to buy more later (then you get to do a redesign!). Moving to a high-res display also adds bunch of new graphics/UI work and you need a beefy uC to be able to move those pixels around. Might as well put Android on it... and then you are flying down the rabbit hole..

I do think they should have at least used a white on black LCD like someone else mentioned, what they have now just looks dated.

Increasing bit depth from 24 to 32 isn't destructive in any way and can be done perfectly. It's just tacking 8 zeroes onto the end of the binary number. It's the same idea as changing a 0-10 rating scale into a 0-100 rating scale by multiplying everything by 10.
