     1.4 +The program provides an alternative partial implementation of the PulseAudio 
     1.5 +API. It consists of a loader script and a number of shared libraries with the 
     1.6 +same names as from original PulseAudio, so applications could dynamically 
     1.7 +load them and think they are talking to PulseAudio. Internally, no separate 
     1.8 +sound mixing daemon is used. Instead, apulse relies on ALSA's dmix, dsnoop, 
     1.9 +and plug plugins to handle multiple sound sources and capture streams running 
    1.10 +at the same time. dmix plugin muxes multiple playback streams; dsnoop plugin 
    1.11 +allow multiple applications to capture from a single microphone; and plug 
    1.12 +plugin transparently converts audio between various sample formats, sample 
    1.13 +rates and channel numbers. For more than a decade now, ALSA comes with these 
    1.14 +plugins enabled and configured by default.
    1.15 +
    1.16 +apulse wasn't designed to be a drop-in replacement of PulseAudio. It's 
    1.17 +pointless, since that will be just reimplementation of original PulseAudio, 
    1.18 +with the same client-daemon architecture, required by the complete feature 
    1.19 +set. Instead, only parts of the API that are crucial to specific applications 
    1.20 +are implemented. That's why there is a loader script, named apulse. It 
    1.21 +updates value of LD_LIBRARY_PATH environment variable to point also to the 
    1.22 +directory where apulse's libraries are installed, making them available to 
    1.23 +the application.
    1.24 +
    1.25 +Name comes from names of both ALSA and PulseAudio. As aoss was a 
    1.26 +compatibility layer between OSS programs and ALSA, apulse was designed to be 
    1.27 +compatibility layer between PulseAudio applications and ALSA.
