Tja, isprobao sam, foobar stvarno zvuci bolje nego winamp. Razlika se jasno cuje, pogotovo bolje definisan zvuk u nizim frekvencijama. Koji blam za winamp, posle 10+ godina razvoja.. verovatno imaju bug u FLAC dekoderu ili DS outputu.

ps. Nisam primetio razlike izmedju Foobar "Direct Sound" i "Kernel Streaming" moda.

Cheers, maestro Riviera! Welcome to our HTPC mussings. ^_^

@Gerner: Heh. I'm amusing myself with an almost-vintage mazda sport car these days. If I manage to fix it, we'll be in VS in a jiffy. It's quite adorable but in an awkward condtition, will require a lot of work to bring her up to speed. Pic: http://speedy.rs/pics/IMG_0136%20small% ... 0plate.jpg

Just a short update - friend and I did some improvised A-B testing between foobar & winamp playing flac, and although I thought I could distinguish the difference, seems it's very hard. The second test, between .mp3 320k CBR and .wav was much easier to distinguish. MP3 sound signature adds roughness / peaks to the vocals. (sq is not that bad considering the file is 1/5 of the original size, 5:1 compression)

I'm curious about winamp vs. foobar because I was positive I heard the difference previously, esp. in the bass definition.

@Gerner: I'll drop by waaay-waaay before 'zito and sitni kolachi' day, no worries!! :oky

I've tried playing music from a brand new HP ProBook laptop, Windows 7, run from battery - noise floor is lower then my amp's very quiet hissing noise when it is idle. Laptop analog output sounded ok, but needs more testing - i'll update this thread when I test it some more.

Sta se podrazumeva pod tim "tried" - ako moze malo vise detalja?


Inace u letnjem dvobroju WHF-a sam pisao uvodni tekst o trenutno najjacoj seriji HP laptop racunara - Envy, model Envy 17. Prema dogovoru sa urednikom, nadam se da ce do kraja godine biti uradjen jos jedan test gde ce se malo detalnjije istestirati funkcionalnosti vezane primarno za audio i DVD/Blu-Ray sekciju.

Za sada nisam radio listening testove, samo sam ga prikljucio, poslusao prag suma, pustio par pesama da se vrte u pozadini dok sam radio nesto drugo.. Nisam obracao paznju na kvalitet zvuka, ali nista ocigledno nije bilo lose.

Svidja mi se nizak nivo suma na audio out-u, jer to daje solidnu osnovu da se na njega zakaci dobar externi DAC preko firewire-a (za stereo) a CPU/GPU je dovoljno mocan da se usput moze koristiti i kao HTPC za pustanje videa.
