In addition, most such software is optimized for speech rather than music, so sustained musical notes can be misidentified as background noise and filtered out (although this can be alleviated to an extent via settings such as "Enable Original Sound"). Conferencing software is also often designed for one person to be heard at a time (the speaker gets 'focus'), to stop people talking over each other, but this makes playing music together impossible. In addition, conferencing software does not normally allow detailed setting of individual audio streams' volume or
