I’m about 2 years behind the trend – now I can record random noises
and make them my ring and message alert tones, and this is great fun.
Nick (I think) had the great idea of getting some pirate .wavs from
the internets and using them instead of using my own voice.
I downloaded a snippet of Disney’s Pirates of the Carribean song, and
uploaded the wav to my phone. No dice, phone doesn’t play wavs.
The track I recorded is an .amr, though, so lets see if sox can
convert it… nope, it doesn’t know about it. But google mentions
there’s some reference code at 3gpp.org which
will do the conversion. Well, it didn’t at first, but to cut a long
story short because it’s late, xa.bi has links to
the code, which you want to download, unpack, and modify the
makefile.gcc and decoder.c per the instructions there. Then:
make -f makefile.gcc
sox input.wav -r 8000 -w -c 1 -s output.raw
./encoder -dtx MR475 output.raw ringtone.amr
That differs from the xa.bi amrconvert script only in that there’s a
-s option to tell sox to also convert to 16 bit signed PCM, in case
the wav started out as GSM or some other format. The script also
tries to fiddle with the amr after it’s encoded, but that didn’t work
for me; short circuiting it and just loading the amr straight onto the
phone worked fine.
So now I’ve got the glorious pirates singing along each time I get an
SMS. Can’t wait for the monitoring to go off at work tomorrow…
