MP3
we rip our cd's to mp3 not wav or other file,why,smaller file size and quality as good as cd, wav and other files are big and the quality of audio is not better than mp3.




HANDY ANDY VIDEO ON DIGITAL FILES






WINDOWS MEDIA PLAYER FOR MP3 FILES PLAYBACK AND CD RIPS


it comes with windows (free)




SOME ROUGH CALCULATIONS ABOUT MP3's

Say cd file 30MB mp3 file 3MB 5 minute duration
60 x 5 = 300 sec
30MB x 8 = 240Mb
240Mb / 300 sec = 800Kb per sec audio
now mp3
3MB x 8 = 24Mb
24Mb / 300 sec = 80Kb per sec audio
800kb / 80kb = 10
the cd file is 10 times the mp3 file
do i hear a difference in sound quality?hell no not me!
some may do i dont know?
to me cd = mp3 or very close
;) cheers





DIGITAL RADIO vs MP3's

Almost same streams but digital radio goes through further modulation and transmission for that reason i consider it inferior to Mp3
cheers ;)




INTERNET MP3's

I've tried downloading mp3s from sites with lot's of problems
I've downloaded exec youtube converters/downlowders with lot's of problems
then bingo!
after months of failure
i found a site that does the conversion on their servers and you simply downlowd the mp3
www.youtube-mp3.org
works great!
;) cheers





INTERNET MP3's

UPDATE!
this is a better converter
https://www.onlinevideoconverter.com/video-converter
oh people i'm in heaven!
anything you could wish for is free as mp3





AUDIO SYSTEM OF THE FUTURE

***source: computer and digital files(MP3s)
There is no need to use a DAC your computer has DAC


***amplifier (MoNo)
there is no need to use high POWER

***loudspeaker
must be GOOD

That's it




THE FOUR PILLARS OF GOOD SOUND

1) Low Noise (all,source,amplifier,speaker)

2) Low Distortion (all,source,amplifier,speaker)

3) Extended Frequency (all,source,amplifier,speaker)

4) Tonal Balance (all,source,amplifier,speaker)






BREAK IN

The speakers of our systems need to break in for at least 100 hours of playing music,then you'll notice a more natural sound,this is because the drivers of the speakers are new and require adjacement,the amplifiers however don't require any break in and are always ready for great sound.




DYNAMIC RANGE

CD dynamic range 16 bit/ 44.1 khz is capable of 96dB of it maxed to realise that in audio equipment would require roughly a power level 500 watts rms !!!,now who listens at 500 watts?,the highend guys make high power equipment,but they fail,because the listener doesnt listen at that level in an average home room,would go deaf, so,24 bit goes to 144dB even worse!!!. Most recordings on cd's have the same dynamic range of the analog masters minus analog noise, the noise has been taken out through digital signal processing,what this does is they sound better without the noise but the dynamic range is around 60dB not near 96dB.To sum up High-DR and High power suck.




THE RECORDING,THE CROWN OF EXCELLENCE.

The recording is the most important when it comes to good sound,even with the best equipment if the recording is rubbish the equipment will sound rubbish,Mp3 recordings made at home and posted on the internet are notorious of this,this is not to say mp3's are not good just they need people with skills to be made good recordings.




THE Digital Files PLAYER SOFTWARE

Not all players play the same,for example when i play mp3's on youtube player direct from online,it lacks impact,when i convert youtube music and play it on exe programs there again differences on impact,although i haven't tested many player programs,i'm very satisfy with windows media player, suprise suprise indeed.




HIGH RESOLUTION / DEFINITION AUDIO



High Resolution Audio is audio beyond cd-audio,the graph above shows the most common HR/HD standards,there's also DSD a non pcm standard, as you can see pcm is a winner, why go with that stupid DSD, Anyway the graph compares all.




PCM digital AUDIO


PCM uncompressed

CD-audio
DVD-audio
WAV, AIFF
PCM lossless compressed

ALAC
TTA
FLAC
PCM lossy compressed

MP3
AAC
WMA

Mp3 1/10th of cd file, this means 90% data loss and compression, and still sounds amazing, our opinion.




PCM digital HR / HD Files

PCM compatible File formats capable of storing high-resolution audio include FLAC, ALAC, WAV, AIFF

FLAC (Free Lossless Audio Codec)
ALAC (Apple Lossless Audio Codec)
WAV (Windows Wave Audio)
AIFF (Audio Interchange File Format)




LET'S COMPARE PCM digital HR / HD, CD, and MP3 Files size (3 min duration)

WAV 16/44.1 ~ 30MB
WAV 24/96 ~ 100MB
WAV 24/192 ~ 200MB
MP3 ~ 5MB

WAV 24/192 / MP3 = 40, mp3 is 40 times smaller than the wav-24/192 file
unbelievable!
or 2.5% of the wav-24/192 file!




LET'S listen PCM digital HR / HD, CD (3 min duration)


iTUNES plays HR alac,wav,aiff but not flac
anyway the files i played were wav
i could hear no difference in 16/44, 24/96, 24/192
this confirms mp3 is so good if made good recording





Amplifier POWER (Watts) and LOUDNESS (dBs)

To double the loudness you have to quadruple the amp power (watts).
or double the voltage and current of the amplifier.
so if you double the power of an amp the loudness will increase by 1.33
if you triple the power of an amp the loudness will increase by 1.66 etc. etc.

*please note dB is logarithmic unit




Compressed Lossy Pcm Formats

Which is good?

MP3 (Moving Picture Experts Group Layer-3 Audio)
AAC (Advanced Audio Codec -Apple-)
WMA (Windows Media Audio -microsoft-)

1st - MP3
2nd - AAC
3rd - WMA






HR/HD AUDIO Pcm Formats

Which is good?

FLAC (Free Lossless Audio Codec)
ALAC (Apple Lossless Audio Codec)
WAV (Windows Wave Audio)
AIFF (Audio Interchange File Format)

1st - ALAC
2nd - WAV
3rd - AIFF
4th - FLAC






The Recording in Depth

Have already said how important the recording is
but there is the question
is hardware or recording which exceeding which?
let's face it you're not gonna get both at a perfect level
and this means hifi goes out the window
whatever good recording with your good hardware you have you should treasure it
because there is alot of bad recording out there
the reason?,make more money with recordings than with hardware
why?,lower production cost





My View on DACs

Basicly on the market are cheap and expensive DACs but not middle priced
If you decide to go with CD-audio and mp3 your computer_DAC is more than adequate
this of course depending on the brand of computer
Many cheap DACs arent good enough,and expensive ones deliver whatever
the format cd audio quality,see my opinion on listening HR/HD on this page
no difference at all between cd-audio and hr/hd-audio
So avoid DACs they create problems not solve them





My View on HD/HR theory

It's all theory
Practically doesn't make sense
Even an analog 200 watt system exceeds human hearing
Bigger amps have higher noise floor than smaller amps
because of higher magnitude of transistor noise (noise floor)
so for high dynamic range the amp can only go up (more watts etc)
what this means it hurts our ears and the health of our hearing
please see dynamic range on this page

The notion of higher frequency range as better audio is theory as well
Practically we cant hear beyond 16khz
higher sample rates are elements beyond human hearing (ultrasonics)
so even when the waveform looks smoother we can't hear it as better
In vision yes HR/HD is real
In sound No





THE Digital Files PLAYER SOFTWARE
Update!


iTUNES for me is better than windows media player
Nothing to do with sound
It comes down to computing power and flexibility
Like google-chrome is better than internet-explorer
cheers





Regular-MONO vs hifi-MONO (the difference)


Most people when they hear mono they think regular-mono
and the internet is right defining regular mono
however what i'll tell you here is the difference
between regular-mono and hifi-mono
basicly regular-mono uses full range driver speaker(s)
while hifi-mono uses multi-driver speaker(s)
regular mono has no or to put in another way limited
direction and location of sound (with multiple speakers)
and what is said on internet is this type of mono
well, i (gga),use hifi-mono and i'll tell you
that hifi-mono is as rich in audio quality as stereo
but stay with me for a moment
with stereo two channels are used of different signals
or to put it simply different sounds
what this profoundly does is our brain and ears
recognise the direction and location of these sounds
good or bad is up to each person to decide
now let's get back to mono and in particular
hifi-mono
hifi-mono like regular-mono has one channel of sound
and this means limited direction and location of sound
hifi-mono does have direction and location of sound
but in TONE since it uses multiple-driver speaker(s)
even with the drivers a few inches apart
the tone location and direction of sound are perceived by the ears
so it gives you a sense of stereo but way better than stereo
since it's more natural than stereo in my opinion
so this has covered the difference of monos

Cheers
