well crapola. ogg is not supported on my sandisk e140. so i guess i'd better learn how to tweak the mp3 encoding process.

We filled up the device with about 320 MBs of mp3s and a few WMAs we had around. Ogg is not supported, unfortunately (I tried it). Mp3s played without a hitch. Not all of our WMAs worked, though. The old sample I had (from 2000) that was using '20 kbps, 44 kHz, mono' did not play back, while the high bitrate 212 Kbps ZZTop song we encoded with WMP9 did play fine. I will give the Sansa the benefit of the doubt, though, in this case, as that old WMA might have been encoded with bugs in it.

i have had zerp problems with wma's, but i don't want to support anything winblows....

is there a program that i can use to rip cd's into ogg's? i hear a rumble about LAME. my understanding is that is a console based encoder.

lame is console, but most gui rippers/encoders give you a graphical interface to it so you don't need to use the command line. Grip is probably the most popular gtk app, but there is also dekagen/cdparanoia (libmp3lame not included) and I think k3b has an encoder too.

Keep in mind that if you re-encode wma or ogg into mp3 or vice versa, you will not be able to get the same quality as the orignal file. They each use a different method of compression, and different parts of the audio will be compressed...hence an added loss of audio quality.

to rip cd's ito ogg, i use a soft lie k3b (therme must be maby other ways to do that), it rips cd's into wav, and then i use something like that to convert .wav into ogg:

#!/bin/bash
for a in *.wav; do n=`echo $a | cut -d. -f1`.wav; oggenc -q 7 "$a" "$n"; done

oggenc is a free oggencoder, most linux distributions have it ouf from the box... the option -q 7 is for quality level 7, it ranges from 1 to 10.

I run this script from my music directory and every .wav is converted to .ogg

Since disk space is so cheap these days, your best bet is to encode your music CDs to your hard drive in an open, lossless format like FLAC

You can then transcode from your hard drive file format into your favorite flavor-of-the-week lossy format. So if next month you buy an iPOD, you can convert on-the-fly into AAC or MP3 or even ALAC and then download them into your player.

Just my $0.02

disk space is certainly cheaper these days, but still a little pricey in the 2.5" form factor. i just ripped my first .oog yesterday, it sounded lousy and came in at 15.8mb as compared to a great sounding .wma at 6.1mb. seems i need to tune the settings of GRIP. still working this looking to come up with a good-as-wma mp3 encoding.
