Most of them (well, all the ones I've done) give some kind of access to the live data. Perhaps just the current levels for L/R, or full access to the PCM data stream.
For example, BASS has BASS_ChannelGetLevel, which returns a 32bit number. The low and high words (16bits/0-32767) give the left and right levels.
I use that for the bouncy wotsit thing in my little net-radio app.
