Rockbox: Clip+

[Joe4268]

Unfortunately nothing seems to work:

• reformatted card as suggested
• checked mp3s as suggested (all were ok)
• uninstalled rockbox
• reflashed original sandisk firmware
• reinstalled rockbox

Same result after all this unfortunately. Sometime during the first 5 songs it will freeze forcing a long power button to reset (mostly during a song skip when on shuffle mode).

Using the original sandisk firmware is flawless -- no freezes.

I'll post this eventually to the rockbox forums when I have the chance, hopefully later this week.

Wow, really sorry to hear that. I really can't think off what it might be except an undiagnosed hardware problem that shows up under Rockbox but not the OF. I'd would have no idea of how to help with that.

I'd be sure to post all the information as to what build, size of card everything when you contact the Rockbox developers. They may quite possibly pick up a clue from something that is meaningless to anyone else.

Good luck and I hope you are able to get this straightened out quickly.

Thanks -- posted on rockbox forums now!

i have rockboxed my clip+ but i have a problem now.. my pc can't detect my clip+ even i used OF.. so i can't add new songs, i can't access my clip+ on PC now..

how to uninstall the rockbox? i cant access my clip+ because my PC couldn't detect it, even i used OF when i was connecting my clip to PC

[funman]

You need to set the OF USB mode to MSC (not Auto or MTP)

Yay, just ordered my clip+ 4GB, I think I get it in 3 days. As soon as I have it I'm going to Rockbox it, I think.

Hello people,
First post for me here..
I bought a 4GB Clip +, Rockboxed it, and also received a pair of MS1i's, ...waiting for Fiio E5 to arrive..
I want to know about EQ settings and compression settings and Crossfeed settings.
I have read the manual, but can someone break it down for me a bit more???
I have obtained pretty good sound for my MS1's thru the EQ settings I have, but I
just want a bit more info on the subject...

Rockbox plays fine for me, no probs, great product.

Also, will the E5 be a compliment to my MS1i's?

Clip+ is sweet with MS1 without additional equipment, believe me. The only thing I did was to recable MS1, as the cable they come with is too short for home listening (connected to amplituner) and too long/thick for something as small and portable as Clip+. What I did was cut off sansa headphones that come with Clip and weld cable with this small plug to MS1. Unless you're an audiophile and believe in cable voodoo, there's no quality loss. It is VERY important to change MS1 plug to something small - otherwise you WILL destroy your headphone port! MS1 huge and ugly jack acts as lever that breaks Clip+ inside...

DO NOT mess with EQ when using MS1, no way maaaaan!

Compression is not for you either (unless you don't know why you bought MS1)

Crossfeed may be interesting (remember to turn on dithering when using any sound enhancment) I tried it several times but decided to turn it off. Decide yourself.

[TANJENT]

Ok sweet ..
Thats great info..the weld job should not be hard right?

Leave the EQ..really?
Mine sounds sweeter to me after some minor tweaks....

I leave the Q parameters, as I dont know exactly what they do, I know widen the bandwidth, but to the layman, what does it do to the sound???

I will turn off the threshold setting then,
but then I get a lower vol
If set compression correctly, I get a boost on the lower vol sections and keep the highs from clipping. IMO.

Thoughts?

The weld is not hard, opening MS1 is a bit harder though. Search the web. For me the "spoon" method worked best. No need to put your MS1 in hot water! :-)

Ok, it depends on how natural you want your music to sound. MS1 have pretty good bass without any additional tweaking.

The compression is probably biggest sound quality degradder out there. It basicly kills dynamics. If you know Ravell's "Bolero", which starts almost inaudible and ends with nuclear armageddon, properely working compression will set the volume of whole piece to one level, so it sounds equally loud from start to end. Would your really want that?

You should really stop talking nonsense about stuff you have no idea about, it's getting annoying. Just like that idiotic crap: http://www.anythingbutipod.com/forum...ad.php?t=57662

[TANJENT]

dfkt..
Can you give me an idea as how to optimize the settings on the CLIP + when using MS1i's...
Thanks

ps, you like my avatar??

Well, excuse me but - where exactly the things I say are crap?

Citing manual:

"Crossfeed attempts to make the experience of listening to music on headphones more similar to listening to music with stereo speakers."

How does it contradict what I have written:

"Crossfeed may be interesting (remember to turn on dithering when using any sound enhancment)"

Manual: "[dithering] setting controls the dithering and noise shaping functionality of Rockbox.", which is rather cruical when you attempt any sound processing. Your home audio equipment does that anyway, the only reason to have it set to off on clip+ is battery life. You may not need dithering for time stretch or even pitch change, but you want it when you digitally process volume of the sound - that includes adding some data from one channel to another, as done by crossfeed.

Wiki: "Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as "banding" (stepwise rendering of smooth gradations in brightness or hue) in images, or noise at discrete frequencies in an audio recording, that are more objectionable than uncorrelated noise. Dither is routinely used in processing of both digital audio and digital video data, and is often one of the last stages of audio production to compact disc."

Or maybe am I wrong with compression? Manual says: "The Compressor reduces, or compresses, the dynamic range of the audio signal. ". Is it somehow different from what I have written?

Wiki: "Dynamic range compression, also called DRC (often seen in DVD and car CD player settings) or simply compression, is a process that reduces the dynamic range of an audio signal, that is, narrows the difference between high and low audio levels or volumes"

Didn't I write exactly that?

Or did you mean that i was talking crap when I said opening MS1 with a spoon works best? In such case - I am sorry. It worked best for me...

P.S. For anyone interested in what dynamic compression does to our music, here's an interesting read: http://en.wikipedia.org/wiki/Loudness_war

I have found MS1i's sound better with no crossfeeding and little or no EQ adjust and no compression.
Alot more like the Sansa OS

Dithering..i cant hear the difference..

I don't like the crossfeed either. With my Grados, which are a couple steps down from the MS1i, I add a little bass boost and that's it.

[TANJENT]

in the EQ, or just the "Bass" setting?

TANJ

[ssuukk]

If you want your MS1 sound just bombastic - just use bass settings. Parametric EQ would be great to correct Grados if we knew their response curve, though.

In the EQ.....my low shelf filter is set for 100Hz. http://download.rockbox.org/daily/ma...l#x9-1130006.8

The amount of gain I use varies, depending on how loud I am listening at the time.....lower volume levels, I will use a little higher gain setting.

I don't like the bass and treble settings.....they cover too wide a range, IMO. The EQ allows you to be much more precise in your adjustments.

[TANJENT]

What "Exactly" do the Q parameters do to the sound...using MS1i's?
