    I need to do a recording with the following format: A Law CCITT, 8.00 kHz, 8 bits, mono. :shock:

    I'm working with Mac and ProTools HD 7.1.

    I know that the limitations of the Pro Tools system will make me to record initially at 44.100Hz / 16 or 24 bit, but I need to convert the files to the format I've specified above.

    In your opinion, Which is the best way to do this?

    i forgot to mention it is a .wav file

    Oh, i forgot to mention it is a .wav file. So the specs are:

    .wav in CCITT A LAW, 8 kHz, 8 bit.

    Not sure myself, but there are conversion programs on the net for fairly cheap that will do it for you. Just google A law CCITT.

    Yes, I've found few conversors for the Mac OSX, one very cheap (only 10$). I've tried it, but when it starts the conversion to 8 bit, 8 kHz, it goes completely crazy and hangs up... It doesn't work...

    I've found another program, more "PRO", from Audio Ease but it costs more than 300 Euros... while in a Windows environment you need nothing but the Microsoft's Sound Recorder tool to do that, or any other audio software (avoiding Pro Tools) that lets you to customize the wav export settings (i.e. Soundforge or Wavelab). But I was searching for a manner to do that in a Mac OSX environment without having to spend 300 bucks in a conversion software!!

    Break the job up. Do your recording at 44.1/24 using PT, burn to CD, dithering to 16 bits. Take the CD to any Windows PC and rip the tracks to .wav files using Windows Media Player. Then open them in turn with Sound Recorder and Save As in ALaw format.

    Yes... this would be the simplest option, but I'll use Soundforge to convert the files and instead of burning a cd I'll transfer the files via ethernet or in a external hard drive.

    I can't understand why ProTools, being one of the most high-end systems today, doesn't have an option to do that while other programs can...
