Does AAC-LC max 160 Kbp mean ABR or VBR?

Hi!
Apple writes it its specs:
<pre>H.264 [...] with AAC-LC audio up to 160 Kbps [...]</pre>
Does this mean Adaptive Bitrate(ABR) or Constant Bitrate(CBR)? CBR means allways 160 Kbps, ABR means 160 kbps on average (sometimes more).
Does Apple TV support 160 kbps ABR?
best regards
Andreas

Does this mean Adaptive Bitrate(ABR) or Constant Bitrate(CBR)?The H.264 codec supports VBR and CBR. The default is CBR for TV is, AFAIK, CBR.
CBR means allways 160 KbpsNot necessarily. QT allows three quality settings -- some allow a deviation in data rate in order to maintain target sampling rate.
Does Apple TV support 160 kbps ABR?AFAIK, no -- only CBR with settings you will find under the audio tab in the "Movie to MPEG-4" export options window.

Some people, myself included, import their music from original audio CDs. When doing so I choose to import using Apple Lossless format so as to keep the full original quality of the audio CDs (this is after all why it is called Apple Lossless format in that you are not losing any quality).
The drawback of doing this is that the music files take a lot more disk space than a lossy format like MP3 or AAC. This is these days not a problem on a computer as hard disk space is now cheap an plentiful but it can be a problem on a flash memory based music player like the iPod Shuffle, iPod Nano, iPod Touch, or iPhone as these have far less capacity.
Therefore Apple now let you turn on this option to automatically convert from Apple Lossless to AAC when syncing to one of these music players. As a result on your computer the music is still kept in the full lossless high quality format, but is converted and transferred as a much smaller but slightly lower quality for use on these music players. As with an iPod you are not listening in a quiet room with high quality speakers you will not really notice the difference in quality.

Is there a C version that does what the MAX 1-D Interactive does?

Is there a C version that does what the MAX 1-D Interactive does? Or a solution to the problem below.
I got the MAX 1-D Interactive to work with my stepper motor. The hardware setup is at the bottom.
I am trying to write a C program in Visual Studio 2010 to control a stepper motor. I found an example program called 1D Straight Line Move.c in
C:\Program Files\National Instruments\NI-Motion\Documentation\Examples\NI-Motion Help\C
I copied the example file and the needed .h, .c and .lib files into a Visual Studio project. I changed the velocity, acceleration, and deceleration to match the values in the MAX 1-D Interactive. The solution builds, but when I run it I get the following error message
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.
Setup:
I am running the latest NI Motion Software.
PXI-7334 connected to UMI-7774 using I/O Motion cable
UMI-7774 connected to P70360 Stepper Driver using control cable
P70360 Stepper Driver connected to NEMA 23 (T21NRLC) using Orange (A-), Black (A), Yellow (B-), Red (B)
NEMA 23 is powered by 120V AC power supply
P70360 Stepper Driver is set using DIP Switches (I tried to use the P7000 software tool that came with it, but it never found the driver):

No I am not using Visual C++ MFC. I am using an empty C++ project in Microsoft Visual Studio 2010. Although I eventually want to create a .exe file from this project so I'll have change project type.
The motor runs using MAX to control it.
It did run using the 1D Straight Line Move.c project, but it gave me the below errors. That night I unplugged it because the stepper motor gets hot. The next day MAX still moves the motor but the 1D Straight Line Move.c project doesn’t and I still get the errors below.
I am getting two errors: (I was getting the same errors yesterday)
Run-Time Check Failure #2 - Stack around the variable 'errorCode' was corrupted.
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.
I think the errors come from using the functions in flexmotn.h. The functions look like they are being used correctly, but I can't find where they are defined. They are probably defined in FlexMS32.lib.
I attached the files I am using.
I haven’t tried any of the other examples. 1D Straight Line Move.c looks like the simplest and closest to what I want to do.

What does "network connection has timed out" mean?

It means that the destination server is taking too long to respond. This can sometimes be resolved by closing safari and reopening it, turning off your modem, and then after 10secs turning it back on, or if you have and airport extreme/express, or Time Capsule, restarting those.
Good Luck

What does call failed and call busy mean?

I call my bf on Skype every time I see him on there and it rings and eventually it says call failed and sometimes it will say call busy, what does call failed and call busy mean?

WuTom wrote:
If a call is marked as "Call ended" does this guarantee the other person ended the call, or can it also mean the call disconnected or was dropped?
Was talking with someone and at one point the "Call ended - call dropped". Few other times it was just marked as "Call ended", they have bad internet. So is it possible the "Call ended" means the call was dropped due to internet or were they for definite hanging up?
Thanks
Hi WuTom,
From experience, it depends on the platform which you are using. In my case, my boyfriend is using Skype for iPhone and I am using Skype for Mac. Sometimes I find that the "Call ended - Call dropped" is the result of bad internet on my or his part. "Call Ended" on its own could mean one of two things, among others:
1. A person accidentally touches the red end call button; or
2. Skype crashes unexpectedly (either because of internet as you said or other issues such as flat battery)
This is just from my personal experience, but I do hope it clears some stuff up for you.

AAC Encoder at 320 kbps...

Hello all,
I'm new to the forum. I've had to erase my hard drive and ipod of everything so I've lost over 3,000 songs and have to re-import all of my music
The question is: I am assuming AAC Encoder at 320 kbps is the absolute best sound quality that I am going to get? I will be playing my music through my vehicle speakers and I want near CD sound quality!!!
The other question is: What can you tell me abou the other selections of encoders for importing?... I've searched the forums and haven't found anything, nor did I find a itunes manual.
Thank you all!!!

WAV and AIFF both are uncompressed audio formats.
WAV is mainly used on the Windows platform and AIFF on the MAC platform.
These formats can be read and edited by virtually all players and audio editors.
There's one disadvantage. They produce huge files of about 10 MB/minute of audio.
To reduce file sizes, people invented compression techniques.
Some of them succeeded in creating a codec (encoder/decoder) that will retain all audio information but reduce the file size to about half the size of WAV and AIFF.
Examples of these are Apple Lossless and FLAC (not supported by iTunes).
Your iPod (except the iPod Shuffle) supports WAV, but it will quickly fill up with those huge files.
Like Chris suggested, you should rip a song at different bit rates and try to determine what is best for your situation.
It all depends on your ears (hearing) and your playback system.
In my car, I can't even hear improvements above 128 kbps AAC.
