I use Logic X for nearly all the production work at YoPo Music. However for some lesser well known file conversions Audacity is a free programme that can be really useful.
To convert an ordinary WAV file to u-law CCITT 8 Hz mono in Audacity, this is the method I use.
- Open the WAV or other format file in Audacity
- Set your project “rate” to 8000 Hz (bottom left hand corner of window)
- If you have a stereo file then to convert to mono click the drop down menu in the track header and choose “split stereo to mono” then delete one of the 2 mono streams (see pic)
- Then to save your new file go File/ Export/ click “other compressed formats”,click “options” and choose “WAV (Microsoft)” as Header and “U-Law” as Encoding.
