If your project is stereo, convert all tracks to mono using “Tracks menu > Stereo Track to Mono”.
Set the project rate to 8000 (bottom left corner of the main Audacity window).
In the Export dialogue screen, select “Other Uncompressed Formats” as the file type, then click on the “Options” button.
In “Options” select “WAV (Microsoft)” as the Header and “U-Law” as the Encoding.
8 bit export is not an option with above (Audacity 2.03, snow leopard latest updates, even java working). (Recorded in mono, 44.1 16 bit pcm sampling, 8000 in project window bottom left corner, export, other uncompressed formats, microsoft wav and U-law selected) .
once exported and inspected with an external program (VLC, latest macosx) it still shows 16 bit PCM. Oh and the phone systems works it out too, rejected again…
I have to use my old xp VM and sound recorder to get it down to 8 bits.
I registered for this site specifically to reply to this post and express my gratitude…
I know this was eons ago so I don’t know if Steve is still around…
This info SAVED MY SANITY! I am not a tech person and had to upload a voice greeting to my business phone system with these specifications. This process claimed 3 days of my life. I stumbled upon this thread and now I’m up and running!! I still don’t know what CCITT, U-law, or 8000 whatever is but I’m good with that.
So Steve…if you are out there… THANK YOU x 1000!!!
