qtaacenc: a command-line QuickTime AAC encoder for Windows Options

[DARcode]

I found serious bug in my code. New version is uploaded, link in post #307 updated.

Thanks, batch file to gather the QT files unchanged?

Thanks, batch file to gather the QT files unchanged?

Yes. Works with Quicktime 7.7, but wasn't tested with earlier versions of Quicktime.

Only thing I had to do was change %ProgramFiles% to %ProgramFiles(x86)%. You may want to include some sort of x64 system check which redirects the script to a separate section to copy to that folder instead. You could do a

CODE

"if exist "%WINDIR%\SysWOW64"

statement to check if it's an x64 system.

What about this version -

CODE

setlocal
if "%ProgramFiles(x86)%."=="." goto win32
set prf=%ProgramFiles(x86)%
goto nxt
:win32
set prf=%ProgramFiles%
:nxt

^^ Nice, I wasn't aware of the ProgramW6432 variable.

[DARcode]

Guys, nao has already and politely asked to keep this thread qtaacenc related, there's a separate one for qaac.

@nao: would you be OK with integrating the necessary code by lvql into the official build to enabel portability please?

@IgorC, lvqcl or anyone in the know: what's the advantage of keeping the sample rate @ 44.1 KHz when going for bit rates >= 96 Kbps plus low pass? Quality loss during resampling by design or bug?

For those, who don't want to run the QuickTimeInstaller.exe, here is a modified version of the batch file:

It copies the same files to the same folders as lvqcl's batch, but uses the unpacked installer (possible with 7Zip) as source. This batch file, the unpacked QuickTime.msi (as folder QuickTime) and AppleApplicationSupport.msi from QuickTimeInstaller.exe have to be in the same folder as qtaacenc.exe.

Convenient, thank you.
So basically with QuickTime.msi unpacked to .\QuickTime and AppleApplicationSupport.msi unpacked to .\AppleApplicationSupport in the same dir as qtaacenc and the bacth file, right?

Thanks for pointing this out. Not only will it be appreciated by nao, but it also inspired me to combine several threads about QAAC, including replies by its author nu774; I ask that users keep discussion of QAAC there. Thread:
QAAC discussion, questions, feature requests, etc.

Hi, can anyone tell me anything about the mysterious channelmapping-issue?
You sometimes hear a drop about that, but I never experienced it personally, so for me, its kind of a hoax.

When, and under which circumstances does the error occur?

I did ac3 and dts in various bitrates, and everything was fine. (spectrogram in fb2k)

confused...

Any version of CoreAudioToolbox.dll after 7.6.3.0 applies and incorrect channel map on multichannel files:

http://sites.google.com/site/qaacpage/news/aboutquicktime77

You have two options - get an older version of CoreAudioToolbox.dll that was mentioned earlier in this thread, or use qaac.exe instead of qtaacenc.exe because it automatically remaps the channels for the newer versions of quicktime.

Yes, thats what you hear about this issue every now and then...

buuuut.... i`ve used it for 5.1 dts and ac3 compressions for my personal archive, and I never really seen the error. A fb2k-spectrogram looks like this. Original left, after the break in the middle its the qtaac-output. It looks like everything is in place...



Any comments about this?

[lvqcl]

And what's the version of CoreAudioToolbox.dll in your system?

[dispatcher7007]

Its a quite new 7.9.7.3!

sorry, for not including this, but i thought it would be obvious that its a new one....

Still no word from nao if he'd be OK with integrating the necessary code by lvql into the official build or if he's planning on implementing portability himself/differently...

Can please anyone excuse my ignorance and explain what the advantage of keeping the sample rate @ 44.1 KHz when going for bit rates >= 96 Kbps plus low pass is?
Anything like unavoidable quality loss during the resampling or generated by buggy code?

[C.R.Helmrich]

Can please anyone excuse my ignorance and explain what the advantage of keeping the sample rate @ 44.1 KHz when going for bit rates >= 96 Kbps plus low pass is?

You mean 44.1 instead of 32 kHz? The former allows for improved time resolution (at the cost of slightly reduced frequency resolution) because the frame durations are shorter.

There are a lot of variables.

Advantages (+) and disadvantages (-) of keeping 44.1 kHz sample rate:

(+)Time resolution is higher. But it aslo depends of bitrate and encoder.
(+) AFAIK Apple's resampler isn't the best around here.
(-) You will need more bits to keep the quality.

Apple encoder applies lowpass 15.7 kHz (96 kbps, 44.1 kHz) but it doesn't mean that there is absolutely nothing above that frequency limit.
Public test has shown that it's not bad at all to keep native samplerate. Now if it's better or worse on average it depends on a lot of things.

Could someone please test the Version of CoreAudioToolbox.dll which I supplied, and verify, that there is no channel mapping error?

Here is the link again: http://www.multiupload.com/DWIF3EEIGY

Is fb2k spectrogram the right tool at all to find such an error? If no, which is a right tool for that, because I dont know any?

Id like to use the QuickTime AAC for my compressions, but not, if I screw up my collection with it.

[b66pak]

for me it is not working...wrong channel order (with qtaacenc)...

[dispatcher7007]

is it relevant that i use fb2k as an encoder-interface?

Has anyone got an explanation for the spectrogram I posted above?

For those, who don't want to run the QuickTimeInstaller.exe, here is a modified version of the batch file

Excellent idea. Here is another version of "QT portable" package: http://www.multiupload.com/PW9C8MS719

1. Download it and unpack to some folder.
2. Download QuickTimeInstaller.exe. Copy it to that folder.
3. Run makeportable.cmd.

Note 1: the script will remove all unnecessary files, incuding QuickTimeInstaller.exe and itself.
Note 2: the script should also work with iTunesSetup.exe and iTunes64Setup.exe
