para sakin, ang mp3 is created in a lossy compression, na kung saan nawawala ang ibang information sa paraan ng ripping or burning para makatipid sa storage. kaya medyo hindi na maganda ang tunog ng mga ganitong format.

ang lossless naman, ay walang nawawalang imposmasyon bit by bit mula sa original kaya the best ang tunog neto, pero malaki naman ang space na makakain nito.

galing talaga ni master coolet +1

cguro noon mahirap mag-store ng flac.. pero ngayon sisiw na sa mga flash drive

na try nyo na ba compare mp3 @ 320kbps at flac ? mas malaki parin ba file ng flac? problema yata sa flac ay ang portable player.

Prang audiophile grade na rin ang mp3 at 320kbps.

Woots29 · « **Reply #6 on:** September 17, 2011, 07:31:10 AM »

mas malaki pa rin ang flac

mas malaki bitrate nya eh. may file akong flac dito

19.6Mb ang size nya 3.50minutes

kapag inencode sa mp3 320kbps nagiging 8.80Mb ito

triny ko i-encode ung flac sa 96khz 24-bit naging 70mB ung file

attempt ko rin na 100% VBR MP3 yung encoding 6.31MB

base line na ito. lossless is lossless. PERIOD.
two-channel 16-bit PCM encoding ang ginagamit nuoon sa CDs, uncompressed (di pa uso ang compression)
there was days na kelangan pa lagyan nang mpeg cards ang sony playstation at audio component para lang maka play nang MP3 at VCD.

lossy pa din ang mp3 at 320kbps. kya don't say "prang"
a simple comparison nang raw (dat or wav) to lossless and compressed is makikita sa spectrogram mismo
compressed audio to roll off at 16khz. (sa lossy/compressed kasi hindi na masyado perceived nang utak natin ang ganitong frequencies.)

very dependent ang mp3 sa psychoacoustics. may papers about na ang mga tao "ngayon" is mas gusto ang tunog nang mp3 kesa CD audio.

good morning elab.

Nangyayari ba sir insomartin na ang reproduction natin ngayon ng audio cd ay di rin ganun kaganda kumpara sa old school vinyl at tape? Ano nga ba ang meron sa vinyl noon?

insomartin · « **Reply #13 on:** September 17, 2011, 09:02:09 AM »

technologically advanced ngayon without a doubt. mas maganda ngayon than vinyl.
nakarinig kna ba nang plaka, tape at CD?

Johannah Aleksandria · « **Reply #14 on:** September 17, 2011, 10:14:19 AM »

I missed the times when i was using vinyl.
There is none a lot of conversion in vinyl, you can source it directly to an RIAA equalization and a Class A amp, and I think, with just two transistors for solid state, or two valves, and you have the purist sound available.

insomartin · « **Reply #15 on:** September 17, 2011, 11:50:17 AM »

sorry hindi golden ears meron ako.

with hiss, crackle and pop sa vinyl, slow/lag response nang cheap needles. even a single speck of dust...
tapos eto ba sinasabi mo na eq standard? http://en.wikipedia.org/wiki/File:RIAA-EQ-Curve.svg

where's the original hi-fi? anyways.
pa thread close na po. para hindi na maiba ang thread.
madami ma mis-lead about compression.

"lossless is lossless. PERIOD."

yes tapos na usapan, wag na pahabain pa
ano ba ibig sabihin ng lossless tsk tsk

rdpzycho · « **Reply #17 on:** September 17, 2011, 12:44:31 PM »

walang loss.

every part is as is. ang compression niya ay based lang sa digital domain kung merong magkakatulad na information sa tabi-tabi.

good morning elab.

nakita ko rin dati 'to. meron kasing certain effects, like aliasing, 'yung psychoacoustics na ina-apply. parang hinahanap na tuloy 'yung signature na 'yun ng mga tao ngayon. but of course, audiophiles - golden ears, are a different breed, kaya ayaw nila 'yun.

danny · « **Reply #18 on:** September 17, 2011, 01:08:42 PM »

iyan na nga yung sinasabi ko eh

bakit kasi tira ng tira pa din eh

kinyo · « **Reply #19 on:** September 17, 2011, 01:54:47 PM »

kapag nadigitized na ang analog signal, meron na loss yun kahit santambak pa bits ng ADC ... in short, technically speaking, there is no such thing as lossless audio codec ... so we end up listening to an approximate of the original analog signal

kahit sa all-analog chain, nadidistort yung signal ... kumbaga sa audio, "hi-fi is in the ear of the beholder"
