Hello Nikos!

Nice job! I compared the pure player with foobar in the study PC (the only one with a Win partition at home) and it sounds very good.
I understand that it's still an alpha release but keep up the good work!!!

I guess, the next thing to do, after debugging any music reproduction bugs, is to improve the UI.

Well done!

4. I have 2 G of memory no harm of having more memory.
5. Turn off Screen after 2-3 min helps.
6. I use a laptop, run on battery if necessary.
7. Remove all unnecessary background programs.
8. Disable all unnecessary ports e.g. Sound card(I am using ext. DAC), modem, etc

I get very low system latency, below 100ms most of the time averaging around 40-60ms, the cpu utilization is below 4% most of the time.

The sound is very clean and balance. Try it.
Totally agree. The next step is to make a good DIY regulated Power Supply.
I made my own for my netbook using LM 338K as a regulator, but for Laptops it will need more effort due to the higher consumption... The best result is achieved together with M2tech Hiface USB2SPDIF which has Kernel Streaming embedded.

I'm using Win 7 SP1 & when I changed Foobar from KS output to Wasapi there was a distinct & large improvement in sound (Foobar under XP using KS output has exclusive control over the soundcard i.e no windows mixer, in Win 7 that's not the case)

Does Pure Player use Wasapi drivers? I see that the windows mixer is operational!

Also, are you converting 24bit to 16bit using SOX for playback?
No, it uses the default windows wave out (which i trust more), so it depends from the sampling rate you specify in Windows. For Windows7: Control Panel\Hardware and Sound\Sound\Playback device\Properties\Advanced. Wasapi is included in future plans, but i'm not sure it will make things better. It will bypass the Windows mixer (resampling etc) but this is not the only factor for a good sound. Pure player is not converting anything, sox is just used to decode mp3 etc to wav, not for FLACs. 8,16 and 24bit FLACs are being played "as is" (decode-load to ram-playback) using an optimised engine written in C.

In the short time I have used it, I haven't noticed any difference with Fidelizer. I use Win 7 SP1 (only on beta release) which is said to be th ebest sounding Win version so far - anybody else using this & tried Fidelizer?
I believe there is no sound difference between wav and flac because the flacs are first decoded and then played...

Pure Player as it is not really a Prototype but rather an Engineering Model. My suggestions are as follows will make it a Prototype:

1. Retain the sound engine as it is and improves on the USER Interface, with the following features:

a. No more DOS cmd display
b. Able to add tracks while player is playing
c. Play next track
d. Pause and Start

and many more, I am sure you can think of. A good starting point is from Foobar. Thanks for listening.

Added to the list



Thank you all for your feedback and comments

No reason, that should be the correct email address. PM me yours & I will send you an email.

I believe there is no sound difference between wav and flac because the flacs are first decoded and then played...

I get the following when I play a 24/96KHz WAV file:
"ERROR: Unsupported/invalid WAVE file, only 16bps stereo WAVE in canonical form allowed
Playing with SOX....."

I don't know if this goes a way to explain the difference in sound between WAV & Flac but WAV sounds more relaxed to me with less of an edge (this is very slight but noticeable, to me)

Interesting, do you encode to FLAC first?

That is why I am asking, sorry the post was aimed at the player developer. This rather specific message is located in flac encoder source code, so it is either a coincidence, or encoding to flac is being run.

Ah, I see. Yes I would be interested in the answer too.

It says playing with SOX & displays real-time values of IN, OUT, Clip, etc. It is also sensitive to other processes that are operating & drops out momentarily (I presume based on other processing tasks). So I'm presuming this is not being run from a memory copy of the file.

BTW, I still notice a sonic difference between 16/44KHz Flac Vs Wav
