This is a 2 steps question 1. Martin said in it tutorial you have a better sound recording in 24 bits. I agree. Question is it worth to recorded in 24bits when you have to down sampling in 16 bits at the end to burn a regular Audio CD . 16Bits x 44.1 2. Which format it is better Aiff or Caf

Hi, 1- Absolutely! 24 bits is the way to go. Just don't forget to dither your audio when you bounce to 16 bits. 2- In normal situation, I would choose AIFF because .CAF (Core Audio Format)is a new format and AIFF is more standard. CAF files is better in some situations. For example, CAF files don't have a maximum file size so you can record as long as you want. AIFF is limited to 4 GB.

What dither is or do exactly to audio Thank you AlRobi

Hey Alrobi Check out this post about dithering: [url]http://www.macprovideo.com/forum/logic/logic-pro-express&id=8897[/url]

Dithering is a very interesting and complex subject to discuss. Unwanted distortion is created when reducing bit depth of an audio recording. Dithering add low level white noise to the audio signal and will turn this distortion into a more pleasant sound. Dithering is also useful when reducing the bit depth of a digital image.
