There have been many threads about this but it would be good to hear from npetralis as to what he is addressing in his software that improves the sound i.e is it can't be background processes being closed down, can it?

Yep, that's me - excellent amplifier, a really captivating sound that gets your foot tapping.

Well, that is certainly the case. But I wonder how you can control that on a consistent basis from a single playback application on a complex desktop system running dozens of other processes and kernel threads, many of them even outside of reach of the user the player runs under.

Honestly, I have never seen any credible explanation by authors of closed-source players claiming their product is sonically superior to other bit-perfect players.

Sorry, when I missed it.

What kind of codec are you using for flac decoding and playing?

Does your player provide gapless playback?

I wrote a player with ASIO support and gapless playback and I am interested how others will do that.

In my opinion, there are 4 factors that may improve the sound during playback.
1) Media. Sound varies if the source id a normal hard disk, SSD disk , a USD stick, Cd-Rom etc. The best source is Memory, especially when paging to disk is disabled.
2)Track format. The best sounding format is wav. You may decompress a flac and compare the 2 files using Foobar, the difference is obvious.
3)Other processes-CPU utilization. It's hard to control other processes, so one solution is to run your player in High process priority.
4)Chunk size and latency when "talking" to Windows wave out. This is real alchemy-Voodoo, so trial-audition-error seems to be the only way...

A good non-switching power supply when possible helps too

Flac decoding and playback engine is written in C, using the "official" libflac.
What do you mean by gapless? The player buffers the whole file and then plays it. You can check the readme file for more information (or click the red pepper).

Just a wild guess, but I think he may be referring to back to back file playback and loading times creating gaps.

Sounds like a credible explanation for the percieved difference between players to me.
