FW: mp3 on IPX (was [SunRescue] BSD Questions)

[MikeHebeldruaga at pmail.net]

Just FYI.  Here's the mpg123 line I use to play my .mp3 files on my IPX.

mpg123 -4 -r 8000 -m --8bit --aggressive -a /dev/audio my_mp3_file.mp3

The -4 does 4:1 downsampling, the -r changes the rate to 8khz, the -m is
mono mode, --8bit is (yup you guessed it) --8bit mode, the --aggressive
tries to attain a higher priority, the -a is the audio device and then the
name of the .mp3 file.

This works.  The sound quality is not the greatest but it does work and is
fine if you don't happen to want to dedicate the CPU cycles on your bigger
boxes to playing .mp3 files.

I think I'm going to hang a big SCSI drive off of the back of this box,
replace the 8-bit audio with something else.  (I think there are some SBUS
sound cards out there somewhere.)  Then I can just load a few hours worth of
music on it and let it play. :-)

Most songs come out "ok" and the IPX seems to work nicely for background
music.  Having the external speaker cable and speakers helps.

The biggest thing is the sample rate at which the mp3 in question has been
recorded at.  The 128k(?) samples play too slowly most of the time but the
44k(?) ones play fine.  (Forgive the ? marks but I have not had coffee yet.)

The low overhead of NetBSD on the IPX helps.  <joke>Seti at home and mp3's
don't mix.</joke>

I'm going to try playing them on Solaris 7 on my SS2, 64meg, non-PowerUp
system and see what I get.

How are the results on your IPC/IPX/SS2?  They only have 8 bit audio so
I haven't pursued playing mp3s because I figured they'd sound terrible...
