Store 325+ songs in 1 gb card in full quality .

For higher bitrates like 128 Kbps, why would I use mp3 when 128 Kbps LC-AAC provides similar quality to 160-192 Kbps mp3.... tell me this first.. !!!!

dude we are here to discuss abt space conservation in mobiles.......not for pc playback of 192 + kbps quality......

1. all songs we get from cd's are mp3's of 128-160 kbps
or even higher

but why one should waste time to converte these all to LC-AAC above 128kbps?? , if mp3 is providing me excellent quality at its simple available original bitrate .....thats why dude ........i prefer MP3 at high bitrates ....no need to convert ....its readymade .....

Use ur PMP and then tell me which sounds good and which doesn't...

Have already tested and played songs in N70 , 3110c , 5200 , 5700 and N73 ........even 64 kbps he aac stream sounded evryone (me , ma bro , ma friends and all respective mobile owners ) equal to 160 kbps mp3 !! in all phones above !!

To be precise, we are here to discuss about space conservation with optimum quality... read my earlier post back as I have added a few things which u have definitely missed due to fast posting ... I am not talking about PC playback but playback on ur PMP and I have repeated this fact in every post...

wow. how this discussion changed its course .. phew... good nite.. its too late for me already... !!!!

plese refer post #21 again and.....

yes i have mentioned it in each and every post........

that for mobiles 80 kbps HE AAC is just enough to listen songs at optimuuuuumesssssssst quality .

and dude what are you trying to say ?

for your LC-AAC stuff.....----->

see this graph and tell me which encoding technique wins ?



*img441.imageshack.us/img441/2593/22243549mo6.jpg

didn't they all meet at 128 kbps ?

between 108 to 128 kbps all the three encoding techniques have same quality .....

isn't even 80 kbps he aac better than 96 kbps lc aac .....which contradicts your earlier posts this :- ---

have compared 80 Kbps HE-AAC to 80 Kbps LC-AAC and both to 96 Kbps LC-AAC.... the order is:
96 Kbps LC >> 80 Kbps HE >> 80 Kbps LC....

one more thing , even AAC main is better in quality than the LC-AAC at 96 or 128 kbps .....

so dude correct urself by reading this

AAC Main - This is the deluxe model that includes all the tools available and delivers the highest quality audio. [/FONT][/FONT][/FONT]
[FONT=arial, helvetica][FONT=arial, helvetica][FONT=arial, helvetica]AAC LC - LC means "low complexity." It reduces audio quality while also reducing processor demand. [/FONT][/FONT][/FONT]

There are three profiles for the AAC standard, called Main Profile, Low Complexity Profile, and Scalable Sampling Rate Profile. The Main profile is intended for use when processing, and especially memory, are not at a premium.

i think i did a mistake of not posting it before


even i have posted this thread after a lot of experiments and results ......

[ratedrsuperstar]

for those who don't have ears of carnivores.here's how to do it easily

1.Use mp3gain and set the volume to 98-100db for every song(some songs which have volume about 90-92db might crack if there's heavy bass).so always first analyse them.

2.Use Xillisoft video converter to convert to .m4a.use 32kbps bitrate and 44100 frequency.The normal version allows for 5 min of transcoding per file.
the best part is that it's VBR so the bitrate is maintained according to the complexity in sound at that moment.
the result is 75-100kbps of LC-AAC.

3.Use Winamp to edit tags.

i've 523 songs in 1.3gb in my mem-card and quality is same to that of mp3's of anywhere between 128-320kbps and 96-192kbps WMA.

guyz why fight over whose's graph has more slope/area under the curve,etc.lol.it doesn't matter if your screen has a few dead pixels while watching a 1080p movie.

@expert no1 U used a lot of time for this thread to compile but
buddy i dont think so that ur thread woth any appreciation coz
.... i agree AAC have better quality on lower bits
but only if played on desktop speakers....

In mobile less RMS speakers appr. all bitrates are same.... (if converted properly)

I can bet you in quality that i'll give you even less size MP3 file compared to ur AAC (whatever be the version) and quality is great even better than ur AAC (only in mobile speakers.......)

Method: Use mp3 cutter n joiner
in settings set minimium bit rate at 32 kbps MONO n quality 3
now goto Variable n set it to 64 n quality 2 (encoding MRAH)
click on FORCE minimum bitrate

n now get 1.9 mb file size for 5 min song n again i can bet u'll get
great sound with convetional everywhere used file type....



one more thing... i have near about 180 mp3 songs,,,
2 full 3 hours movies,, 28 avi songs,,
~30-40 softwares all converted by me on my 512 original mmc

 

[kalpik]

Well.. I've tried LC-AAC, HE-AAC, HE-AACv2, Ogg AoTuV, all at 64 kbps. To me Ogg always sounds the best! Im not saying Ogg is better than AAC.. Just that probably my N70 does not support HE-AAC, as the file sounds right on PC, but it sounds muffled on the phone Probably the phone discards the SBR part of HE-AAC.

 

[ratedrsuperstar]

@hac_king - we're not talking of speakers they sound so lame on every phone.and if you keep audio in mono whats the use of listening music.do you have some mono phone?

 

[x3060]

i downloaded and heard the music in my k750 just now . . and i would not recommend it at the present quality . its full of bass . sounds too bad. i suggest you up the quality settings . .you made that song horrible to listen

i must add . . the mp3 that you gave along has richness in it . . but it sounds bad too - did you rip from cd?, i dont think so . . please provide a sample that you can rip from cd.

am on phone now . . edit the above -i need a sample that you ripped from cd. in both formats , thats all . with the current settings the mp3 is far rich.and the other is not

Dude N70 doesn't decodes the HE-AAC part of .aac file

dude you have to convert it in .mp4 / .m4a ...then it will recognize and

decode the SBR part ...even it supports PS tooo./ N70 rocks !

@x3060 ....dude does k750 supports AAC+ ?

in gsm arena its given mp3/aac player not eaac/eaac+ player ......

if it doesn't supports eaac then there will be no quality in song bhai ! it will be full of bass .....no SBR !!

i had already mentioned in the first post that only the phone which have eaac support will work !

.... i agree AAC have better quality on lower bits

I can bet you in quality that i'll give you even less size MP3 file compared to ur AAC (whatever be the version) and quality is great even better than ur AAC (only in mobile speakers.......)

LOL !

i will give you a 24 bitrate .m4a file having Spectral Band Replication and Parametric Stereo ......even mp3 of 64kbps cant beat it in quality in MOBILE SPEAKERS ! .

take a N70 , N72 , N73 or 5700 from any of your friend and play 24 kbps .m4a file (SBR and PS technolgy encoded)

and play your mp3 ....i challenge you that the m4a will sound 100 times better than that !!

Note:- MP3pro has SBR technology but is not supported in mobiles

@ratedrsuperstar hey y its no use for mono??????
In mobile speakers mono is best even if set bitrate to 192!!!!]

Coz stereo sound makes a bit noice on less RMS spkrs like mobiles..

Well r u getting MONO as MONOtonic?????

well i have not checked aac+ , so i guess you are right . i dont have a comp handy to check right now . i just said , when i played it in my phone , it sounded crap . i will test in comp later .

 

[expertno.1]

^^^^^
thanks bro........

check it and i guarantee that you will not be disappointed !

@hac_king

thats it dude and please try it on your N72 mobo ....u have N72 na u posted it in "wmv for s60v3 thread" try the both files and tell me if u get any difference

N72 too doesn't encodes HE-aac of .aac file so you will need .m4a file bro....keep this in mind ....

i think the people here who are telling quality loss is beacuse of this reason only .

so please refer ma first post and follow it strictly !

I tried both the m4a and aac containers.. Sounds the same in both.. I know theoretically N70 supports both HE-AAC and HE-AAC v2, but i just cannot hear the difference. And BTW, an MP4/M4A file is HE-AAC only! AAC is the codec, and M4A/MP4 is the container. So don't think i dunno anything about audio formats and all I urge you to try Ogg AoTuV

dude dude dude.........if you are converting higher bitrate mp3 to higher bitrate m4a ..........it will sound similar bhai !

hear 24-32 kbps m4a he aac , 24 kbps m4a he-aac v2 and 24-32 kbps mp3..........you will get the difference....i too have N70 and you cant fool me

here is the sample....put both in your mobile and tell me which sounds better

m4a_xd (24 kbps SBR+PS 44100 hz 16 bit stereo)
*www.fileden.com/files/2007/12/10/1636697/m4a_xd.m4a

i am sorry if i considered you a kid

Dude i was talking in the case of N70 that it doesn't decodes HE-aac part of .aac extension file but does of .m4a extension........may be because it is made in 2005.....old phone.........not rich supported .

EVEN it cant read the album , title , bitrate , year , etc of the .aac/.m4a songs

AND you can find difference between HE-aac v1 and he-aac v2 at low bitrates only.....coz he -aac v2 works from 16 to 40 bitrate only....and even there is no requirement of he-aac v2 above 48 kbps.

the difference in he-aac v1 and he-aac v2 is that

he-aac v1= SBR technology only ...suitable for bitrate above 48 kbps
he-aac v2=SBR+PS technology ...suitable for bitrate <48 kbps

since parametric part only enhances stereo part of the song at lower bitrates(lower bitrate osngs are almost stereoless in mp3) its suitable for lower bitrates only.....at higher bitrates 48-96 kbps HE-AACv1 is fine and above 96 kbps AAC is just enough.....

even if you set the bitrate of he-aac v2 above 70+ kbps .....it will limit itself to 64kbps .....

and he-aac v1 limits itself to 128 kbps

prcatically above 48 kbps there is no difference in quality between v1 and v2 .

see the graph in post 23

thanks for your reply

keep on.....
