Which file formats does recording text-to-speech in OS X support?

Question

Speech using the say command can be recorded like this:

say -o hello.aiff 'hello world'

What other formats are supported besides aiff? I already tried wav and mp3, and they don't work.

Answer 1

According to man say, the supported file formats are

--file-format=format

The format of the file to write (AIFF, caff, m4af, WAVE). Generally, it's easier to specify a suitable file extension for the output file.

.wav doesn't work since it needs to be written as .wave. No DOS 8.3 restriction here.

It is also possible to specify the data format. See man say for additional information.
