    Question regarding bandwidth

    If I rip my music at 192K and then stream the music to a remote machine
    via a ssh tunnel. What bandwidth would be used to stream the music
    assuming there is no overhead added by ssh (which is incorrect but for
    this discussion I am just looking for a guesstimate). Will it be 192K?

    I would like to stream my music from one of my home machines which is
    behind a firewall and my upload rate is limited by Comcast to 256K.

    By default, connecting to the server from a mote location wtih something like
    winamp will default to 320kbps, softsqueeze would default to no limit. These
    are only limits, so having your music encoded already at 192kbps mp3 would
    simply play at 192kbps, again assuming no overhead in either comcast or ssh.
    This might be a bit choked for your 256k limit. However, you merely have to go
    into the player settings, audio and lower the bitrate limit, then restart
    playback. This way you can find the right setting for your connection.

    Question regarding bandwidth

    By my reckoning, it'll be slightly higher than that.

    Partly because of the SSH encapsulation, and also partly because (if
    you're using SoftSqueeze), there's more than just the audio stream going
    down the wire. There's also all the display updates, and all the other
    chatter that goes on.

    But... remember that even if you find that there's not quite enough
    headroom to get the results you like.. you could always instruct
    slimserver to downsample to 160k or so for that player. Just keep
    dropping the bitrate until you find one you like. That way, you get to
    preserve the audio in a quality you like, even if you have to compromise
    a little on the quality if you want to listen to it at work

    This is SO COOL. I didn't even realize that I can limit the bitrate
    since at home I use a slimp3 and a squeezebox I never had a need to
    limit the bit rate. this means that I can rip at the highest quality
    and still be able to stream to work.

    I cannot believe I missed this option all this time! This is a perfect
    solution. Rip in highest quality and stream at a lower rate...

    Thanks for a great tip.
