Hello,
NIN9 and me recently discussed about audio-codecs ...
he had some .ogg's - I do only have .mp3's and huh whats about .mp4's
Informations / Impressions
OK: one note for those who think MP4 great that must be ... NO!
1. mp3 is NOT MPEG 3 its MPEG 1 Layer 3 but thats very well known huh ?
2. so whats MP4 now ??? MPEG 1 layer 4 ? NO MP4 is just a "container" for the AAC Audio codec so the thing we are talking about is AAC OGG and MP3
I was reading some forum telling that AAC deserves the same quality at 96kb as mp3 at 128 sounds interesting huh ? OK that needs some testing
1. the base is an normal Audio CD
2. the original is a 16bit 44.100Hz PCM .wave file (accurate ripped) 26.4MB
3. now lets code ... sorted by size
- mp4@64kb 1.18MB --> clear difference to the original but not as bad as the 96kb mp3
- mp4@96kB 1.78 MB --> just as the original no hearable differenceto provide ultimate quality/size ratio
- mp3@96kB 1.79MB --> clear difference to the original not worth to keep
- ogg@128kb 2,33MB --> no difference to the original
- mp4@128kb 2,37MB --> no difference to original or 96kb MP4 or OGG@128, but to provide ultimate quality/size ratio
- mp3@128kb 2,39MB --> very close to original but less highs very little but noticable difference
That gives me the followin conclusions:
- .mp3 is out of date
- .ogg is a very nice and free MP3 replacement
- .aac/mp4 sets the new standard in quality and size for compressed music
- mp4@128kB deserves ultimate quality @ reasonable file size
and best of all MP4 can seamlessly replace MP3 since there is already full support by plugins for it ....
OK .... after lots of more testing and so on heres the result:
MP4 encoding Tutorial and Tools
1. get http://www.dbpoweramp.com to encode nearly ANY format to MP4
2. get our little package H E R E it's based on NERO's AAC engine with ENcoder CLI
Beta Phase ended should work like charm now!
2.1 install to get an easy to use GUI for batch encoding and maximum stability/quality
2.2 I recommend CBR @96kb (LC AAC)
- NIN9 would CRB @ 128kB (LC AAC)
- I do NOT recommend using VBR since the NERO encoder is not the best in choosing the right bitrate at time
3. now convert all the music you want to
4. get this great and free tool http://www.mp3tag.de to Tag your MP4 files for maximum pleasure
5. goto here and get the MP4 plugin for www.winamp.com
6. start winamp
7. goto preference choose MP4 plugin and set titel format to "%1 - %2" if you have set Tags
- in filetypes you can select MP4 or more types to associate with Winamp without doing that manually in windows
Additional Tools
x. for those with fullCDinOneMPx file ... mp3cue still works!!!
x. if you search for a supreme renaming tool go http://www.1-4a.com/rename/
EDIT: 02.01.2003
x. there is a way to split AAC files by time with WBIAS feat. BeSplit
or by a cue with CUE_Splitter feat. BeSplit
but remember BeSplit actually only supports AAC you have to transform your MP4 to AAC (without any quality loss). There is a dMC plugin to do this but just as the MP4 Plugin it does not work correctly ... I will investigate this and report back
report additions and any comment here !
happy coding ...

Hi,
thx, very nice guide :hail:
Nice, but there is still a problem:
I like to cut my cdimage.m4a and cdimage.cue with a tool like musicutter close to AAC Frame.
Thats a way to have no audible gaps between the tracks.
Is there any solution???

very good question ... never thought about that .... normally I don't split those files ....
but you may try http://www.digital-digest.com/dvd/downloads/besplit.html
havn't tested it but tell the result

Hi,
first i have compared CUE_File_Splitter_v0.2 with musicutter:
testfile: a 192kbit/sec CBR mp3 File with Cue
both tools have altogehter the same output size, very good.
Individually filez have not the same size, but this is not really a problem cause it is only 3 frames.
CUE_File_Splitter_v0.2 AAC test:
i encoded with foorbar2k + nero.dll+ nero 6.3.x.x aac
in the nero aac settings, i check Export ISO 13818-7 AAC Track, so i get both kind of files (mp4 & aac). I encoded the file with AAC HE preset.
With MP4ui i extract an AAC File from the mp4 file, it works and it has exactly the same size as the AAC file wich cames directly from nero
Cutting with CUE File Splitter v0.2, problem-free :wink:
Last test: get back a cdimage.aac
this is usefull because CUE File Splitter cannot cut 100% exactly, but in the cue file are the exact cutting times.
Here a little DOS Batch File to merge AAC Files together (save the code in join.bat):
For me this is the ideal aac archive
But i still miss one tool:
mp4 --> aac converting tool, with batchprocessing!

I probably don't have much of a "musical ear", because all my music is 128kbps, and I don't actually see much of a difference in a new format. I must admit that Ogg music rocks though, I really liked it when I used it :D
@Crossfire
i don´t use dBpowerAMP.
Maybe you should try foorbar2k + nero encoder/decoder dll:
original posting
for mp3 to mp4 (or m4a) it is almost the same way. Check this out, foobar2k is very small and functional:
- there is no temporary wav File
- replaygain is a very good normalize function, cause it works over one song or over a bunch of musictitles (this is usefull for selfmade samplers)

Maybe you should try foorbar2k + nero encoder/decoder dll:
Preliminary how-to (for 5.1 output):
In the first place you need foobar2000 from Case's site. It is labeled 'special installer'. During installation make sure that AC3 is selected in the optional components/Input section and also the disk writer component. Also you need the Nero encoder/decoder from the same site. Copy the included foo_nero.dll to your foobar2000/components folder. Finally you need a full version of Nero 6 installed.
Now here begins the fun: Add an AC3 file to the fb2k playlist. Now in the preferences look for components/diskwriter. Select 'Nero encoder' as output format. Check that DSP and replaygain isn't used. Now check for 'Nero encoder' component and select "MPEG4 Advanced Audio Coding" as output format. Configure the Nero plugin to your likings. Don't forget to enable 'dynamic range reduction' in the AC3 component settings. Now close preferences again and right click your AC3 in the fb2k playlist window. Choose convert. That's it in principle. You may change the output naming and the output directory.

erm you should have

Hi,
good news: i have found a MP4 --> AAC Converter with Batch processing :angel:
Check this out:
http://home.wanadoo.nl/~w.speek/ivan&menno.htm
this is a nice gui for:
Patched MP4creator For handling AAC audio MPEG version when wrapping in in MP4 - MPEG4ip v 0.9.8.4 - by Enrico Palmeri - updated version
http://rarewares.hydrogenaudio.org/mp4.html
Extract it in the same directory as "ivan & menno.exe"
How to use:
go to the register "MP4Creator" --> Select "Convert MP4/M4A to AAC mpeg version as original" --> Add some Files and set the Output dirctory --> press go --> aacbatch.bat will be generated, start it and voila there are AAC Files :beer:

Hi,
bad news:
the Nero aacenc32.dll has still bugs. It is impossible to playback files without audibable gaps
