An eight-bit resistor ladder DAC doesn't quite put out a very smooth wave, you know. That's why you use a low-pass filter to smooth it out, turning a 256-step "staircase" into a "real" analogue signal.GC_PaNzerFIN wrote:

The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP

trust me
Don't start talking about something else, there are no gaps in analog signal which you could fill at first place. Doesn't matter if its staircase-like or perfect sine wave, manipulating that is what filters do.Freezer7Pro wrote:

If you have trouble understanding what analog means, there is no point in continuin.

Did I say that a filter doesn't manipulate the signal?GC_PaNzerFIN wrote:

No. I said that an RC filter will do a decent job at smoothing out a low-resolution "analogue" signal and turning it into a "real" analogue signal. You can't get a real sine wave out of a DAC like the one I described without some sort of filter on the output, since you only have 256 voltage levels to choose from.

Then what was this all about?
Poor analog signal is still analog signal.

Because they work in completely different ways doing different things. Analogue filters just chop bits off the signal, they don't fill in gaps.

I'm saying the exact same thing in both of those posts. An RC filter will shift the phase slightly, so that it, if shifted back, would attenuate the peaks when a step is taken, and fill in the gaps while the ladder is at a steady state and waiting for the next sample.GC_PaNzerFIN wrote:

Yes, I've never said that it is anything but. But a poor analogue signal of this nature can easily be improved upon with a filter to better match the target signal.GC_PaNzerFIN wrote:

You are not filling anything, you are smoothing out the rough edges of continuous signal with a filter. Compared to discrete world where you can add infinite amount of samples between two points in time.
There are no gaps you can fill in analog signal, not even crappy "staircase"-like. If there were it would not be analog signal.
e: and because you seem to put it in every post, I am not arguing about quality improvements you can gain with proper filters. Because I know those are true. Which is completely irrelevant fact.

Get some different earphones? You could get the Earsonics SM3's for nearly half their price and they're a lot better.Uzique wrote:

I don't know which earphones have the best build though, my guess would be the IE8's or the CK10's.
That's not filtering. That may well be a smoothing by-product of the capacitors that most filters contain....Freezer7Pro wrote:

Yes, just saying that it's adding zeroes at the end isn't quite accurate, but I think it demonstrates the point quite well.
Regarding the sample rate conversion, I can't quite see how any digital signal processing can fill in the gaps better than the filter on the analogue output.
What exactly do you mean by "gap"?GC_PaNzerFIN wrote:

Why don't you get something else? You like that model so much or do you get a really good deal on them?Uzique wrote:

Got a new MicroSD card for my BlackBerry. It's transferring shit from my computer slow as fuck. Even I do just one small file at a time. I reformatted the card using the BlackBerry, too.
Am I doing it wrong?
I have it connected to my computer using USB, same way I did things before. The other card was a 2GB one that came with the phone. This new one is 16GB, made by Patriot.
Err, ok nevermind. Seems to be going normal again.

silly question, but is it usb 2.0 port?
Yeah, I'm 99% sure.
My external HDD gets good speeds (30~40 MB/s IIRC), but this shit is going 4 MB/s at best.

I doubt it has that fast of transfer speeds to begin with...
Looking at wikipedia though, apparently they have the ability to make 2TB microSD cards

While we're on the topic of BlackBerry, is it possible to install a better music application? Better yet, any way to select multiple songs and add them to a playlist in one go? I'm so fucking sick and annoyed with having to click a song, add it to a playlist, go to the next one, add it to a playlist, etc.
Not sure, I always listen to full albums so it doesnt bother me. I use 7digital for last.fm tracking though, it might be possible in that. I'll check
edit: yep, it is. far more advanced as well

I usually listen to full albums or mixes too, but sometimes I just want some shuffled singles.
I've basically got a bunch of mixes ripped as one file, and then have a bunch of random tracks I like. I like to keep the two separate so I can shuffle the mixes and not have to touch it, or just shuffle the singles and not be interrupted with a long-ass mix.

crazy innit, I was reading a panasonic catalogue a few months ago, and was in sheer awe at the fact those tiny little things can hold 4 times as much as my HDDWinston_Churchill wrote:
