In terms of power consumption, it's perhaps more sensible to pair Sansa player with op-amp swapped O2 (TLE2062EP) and enjoy high Vrms out combined with sub-200mW idle consumption, something Fiio and other DAPs have yet to show.

And just in case, you may want to check the ID3 tab to make sure it's not writing ID3 tags to the resulting files? I don't recall if this is still a possible problem with EAC, as I haven't used EAC to rip anything in years.

you can see in my screenshot above that "Use ID3 Tag" is UNchecked.

What do you use to rip now?

The tests were designed to be optimistic, as the maximum recorded level was -10 dB FS. This is about 1/3 of max amplitude.

Are you saying that at 0VU (because that would be full scale) on the LP, that distortion is 15-20%?? If so, the statement is clearly false. Not arguing with the math, but sumthin's wrong with this here picture! I'm thinking the 2% at -35db is not right... 2% at 0VU would be a lot closer...

Measuring the actual distortion is really problematic. You have to remove the distortion in the source and somehow negate the distortion of the pickup and EQ (please correct me if we are talking apples and oranges). But if I recall correctly, 2-3% is an accepted norm, but with proper equipment I think you can do better than that (I use a Triplanar, which might be the most adjustable arm made).

The key to LP longevity, in this case based entirely on my own experience, is to insure that the cartridge is in fact tracking properly. This is the tricky bit as cartridges and arms are not always compatible. But if you get it right, there will be no hint of distortion regardless of the track in question. At that point you get the minimum wear of the surface as well.

I find that the biggest enemy of the LP is improper storage and a failure to handle the media properly.

How about one of their cheaper (not the loudest) product?

Battery life for smartphones can be long or short, depends on user behaviour, doing nothing but play music will have longer battery life for sure.

I like fiio but I don't think the current batch of audiophile players is very good. For example that device gives you about 7db more volume than an average Qualcomm phone in exchange for 128k mp3 playback time comparable to the screen on time of some phones. In terms of power consumption it is easily 10x worse than a decade old mp3 player.  For some people this is fine, but I don't really understand why battery is do poor.

The xudoo x3 is fairly similar (based on a similar reference board as fiio uses I believe).

IME my FIIO  X1 gen 1 equals or outplays MP3s on my Sansa Clip and my Fuse.  Its measured performance is more than good enough, and generally better than the older Sansa products. The Courier font menus are legible, but not all that pretty.

From the spec sheet, it looks like the X2 is still decent.

Every Android phone with a microsd card slot ever made will support up to the maximum size allowed by the standard, which is 2TB.

 No the statement is false because I have inserted a 64 GB micro SD card into the memory card slot of a phone which doesn't support 64 GB external memory but supports 32 GB and I was unable to access the content present in 64 GB memory card.

The above happened a number of times for different phones.

Interesting fact is that when I connect 64 GB memory card through USB otg to an Android phone which doesn't support 64 GB external memory I am unable to access the content.

This report describes a potential false negative indication.

A SD card can be too big or have the wrong format, and from the phone's viewpoint all you will see is nothing.

The "one size fits all"  solution is FAT32.

But Windows won't let you format everything FAT32, even though the device can probably support it.  Once formatted, Windows can see it, too.

To make large FAT32 volumes, there are freeware programs for Windows that will bypass the artificial restrictions that MS put in to force you into EX32 or NTFS. 

You see the patents have run out on FAT32, but are still capable of generating income for NTFS and EX32.

Vinyl / Re: >20kHz content found in vinyl?

What was your procedure?

(1) Obtain a collection of both legacy and modern test records. In many cases obtain 2 copies, one for general use, one for very limited use for tests that were done for "The record".

(2) Obtain several turntables ranging from Ion to Dual to Rega to VPI

(3) Obtain a number of legacy and current cartridges

(4) Do needle drops of selected tracks and analyze them to ensure tone arms and cartridges  are optimized

(5) Take the most promising results and duplicate tests using test records from the reserved group.

(6) Typically unless it mattered, I did some pretty merciless weighting of the results to give vinyl the best chance of developing results that people would not dismiss out of hand because they were so horrible. I edited out tics and pops by hand.

Generally what I found was that once I got the Rega set up well, it was hard to improve on it.  Oh yes, and that compared to digital, vinyl sucks. It measures so bad that it even sounds bad.

I don't know how you could set up a Rega arm well. The arm lacks some essential adjustments, making proper adjustment with most cartridges almost impossible.

If your vinyl setup sucks as bad as you say, its likely that there is something wrong with the setup or the LPs you have are in dreadful condition. You should not be hearing any differences in bandwidth for example, nor any distortion in any passages.

Regardless, wouldn't you also want to subtract the noise of the phono section from your results? Otherwise the measurements might be skewed. Some phono sections are -85 db and some are -55db.

What are the legacy cartridges for?? The cantilever on any cartridge really isn't going to perform properly after 4-5 years!

Look up what file systems your phones support (definitely fat32 and maybe ext4), format your card into one of those, and it will work.  If it didn't work you probably didn't format it to a supported file system.

I'm losing track of how the chain would look like.
So streamer would encode using ffmpeg which would multiplex mic input with streamer output and send it to opusenc?
Code: [Select]


streamer -----------> ffmpeg ------------> opusenc ----------> streamer -----------> icecast
                        /|\
                         |
                  mic input


My apologies, I never muxed with ffmpeg.

Also there's another little issue - when playback stops, the stream is disconnected, as opposed to mksafe in LS.
