Here is what I have going on:
- I record an audio file in 44.1k 32-bit
- I export the file as 44.1k 16-bit mp3 at 192k
- When I reopen the file, it has reverted back to 32-bit
I've tried opening it in different programs, I've even tried converting before export, verifying (in the bottom right of the screen) that the change has been made, saving the original file (with the new bitrate at 16-bit) and then closing AA CS6 and opening it back up. Then when I open the file, it is 32-bit again!
What am I doing wrong?
If you're reopening it in Audition, it will decode as 32-bit because Audition likes to do that. However, I seriously doubt it's decoding as 32-bit in any other application. Please correct me if I'm wrong!
Is there a way to change that in Audition CS6? Not that I know of. Anyone else have something to add here?
That would be my though too. The only other programs that I have, that specify the bitrate with I look, are Logic Pro and Audacity. Logic converts it to an AIF, but it does maintain the 16-bit, Audacity opens it up as 32-bit.
It appears that the two programs I was using to open the file were converting to 32-bit when they open the file.
So yes, I guess my question is now: How do I turn off that conversion?
Actually there is no actual conversion when you open a 16 bit .wav file into Audition. It just fills up the top 16 slots, as it were, in the 32 bit space that Audition works with.
However because Audition always works with .wav files opening your .mp3 into Audition does convert it to a 32 bit .wav file.
You can check the contents of your .mp3 without opening using some software such as MediaInfo, which will report the format and status of the contents of the file.
I'm working on a project that specifically requires 16-bit audio. It'd be
nice to (after the initial recording) not have to keep remembering to
convert to 16-bit, but instead, just make necessary edits in the 16-bit
file. Why would I want to convert back and forth every time I want to make
a small adjustment? That doesn't make sense to me...I guess I could make
it make sense, but I would think that if I want to work in 16-bit, I should
be able to do just that, rather than jumping back and forth.
If you stick with making adjustments to your audio file at the 16 bit Integer level you will lose accuracy every time you make an adjustment which you will never get back. In fact it will get worse the more operations you carry out on the audio. Using 32 bit Float format you retain all the bit accuracy throughout the processes and can go back on them without losing anything. It is when you have completely finished your edit/mix that you can Save As your delivery format at 16 bits. But always retain a copy of the 32 bit file in case you need to go back to make any further adjustments.
By the way you lose a lot of the audio information by compressing to and saving as .mp3, but that is OK for the end product. But whatever you do don't keep saving as .mp3 and then opening that again in Audition to do more editing to then save out again as another .mp3. Each time you go through this cycle more and more of your audio fidelity will be lost.
This was something I was contemplating, based on what has been said so far.
Now that I know how AA handles files, I will definitely maintain a 32-bit
wav master of every file I plan on recording for this project (and any
Thanks! You all have been very informative.
