m4a - codec missing
Hello there
I've just been trying to convert some wav files to m4a or mp4, but Amadeus Pro says it can't create a converter because there's a codec missing, so I had to save them as mp3s. Is there somewhere I can get the appropriate codecs and install them, or what's happening here?
Thanks in advance for your time...

m4a - codec missing
Use the Sound -> Characteristics function to change the sampling rateI'm having the same problem, and haven't noticed any fixes or
relevant bugs or anything. Am I missing something?
to 44.1 kHz. This should do the trick. I will fix the next version so
that it recognises this situation and does the resampling
automatically... Regards,

So the "Sampling Rate" is to be set to 44100 Hz AND what about the "Sampling depth"? 8, 16, 24 bits?
I change the "Sampling Rate" to 44100 Hz and it was then willing to burn, but I do not know what format to use for playing the audio recorded in m4a on a CD.
Thanks Bob

m4a - codec missing
Audio data on a CD is 16 Bit.So the "Sampling Rate" is to be set to 44100 Hz AND what about the
"Sampling depth"? 8, 16, 24 bits?
Sorry, but I am not sure I understand the question? Regards,I change the "Sampling Rate" to 44100 Hz and it was then willing to
burn, but I do not know what format to use for playing the audio
recorded in m4a on a CD.

Well Martin, I think you have already answered it in another thread. You said it didn't matter.
My question arose the when the app. wouldn't burn and if it did and didn't play it would have meant that among other things I burned it in the wrong format for compatibility with the CD player. THe confusion on my part is when you go to save there are a number of options as to the format type that it can be saved in AIFF, m4a, mp4, wave, mpe, AAC ADTS, etc. I didn't know which to chose to be compatible with the CD player. I was told to set the sampling rate to 44.1mHz and burn. I don't understand, but it did work. I thought one of file endings above had to be selected for it to play properly.
If it doesn't matter why do they have so many. It seems the AIFF file is much larger than the m4a in physical size. But I am not really hearing a difference.
I did notice on my CD player the recording level was low or as the volume it played at was low. Is there a way to make the level higher before you burn?
Thanks,
Bob

1) If you are burning an audio CD, everything gets converted to
appropriate CD format -- a format that is a cousin to the 16-bit 44.1khz
aiff or wav file.
2) The other formats are appropriate for saving to disk, transferring to
ipod, etc. The aiff (or wav) is much larger because it does not throw
away any data. The format depends on what you are going to do with the
file.
3) To make it louder, select the entire track(s) and normalize (effects
menu) -.1 dB or 99% for maximal sample value radio button. Under no
conditions, use the other radio button.

Thanks Chuck! Really helpful.
In point 1 you say everything gets converted to appropriate CD format -- I had to set the sampling to 44.1kHz to get it to burn.
Point 2 - So, if I want quality recording I burn in aiff? If it is just audio, that is a lecture. Just set it to m4a or mp3 and burn?
Point 3 - how does a negative .1 dB improve the volume or is this -.1 down from a 100%?

You have to be at 44.1, but any format at 44.1 16 will work
You change the quality when you save the file. You are always going to
in essence burn in aiff format (if you are doing audio CDs). So if you
take the material save it to an mp3 and then load it back in, AP will
re-expand it back to an aiff-like format; of course what was lost in the
saving is still lost.
0 dB is 100% -- that's why 99% is about like -.1 dB -- you are not
amplifying by -.1 dB, you are setting the maximum level to -.1 dB (or
99%) so you have virtually full scale.
