You can do it, for free on your Linux box with lame and sox. Here ya go:
1. lame --decode she_bangs.mp3 she_bangs.wav
2. sox -t wav she_bangs.wav -t raw -r 8000 -U -b -c 1 she_bangs.raw resample -ql
Then you can use the raw file for your Cisco IP phone!
The correct command should be
ReplyDeletesox -t wav she_bangs.wav -t raw -r 8000 -U -b 8 -c 1 she_bangs.raw resample -ql
i.e. "-b" should be "-b 8"
