Audiologger is an audio processing tool from Virage. It incorporates realtime Speech Transcription, Audio Classification, and Speaker Identification. Audiologger can run on the same machine as Videologger, or they can talk over TCP/IP to split the computational stress onto separate boxes.
These days, Audiologger is being phased out since Videologger now has the capability to run audio through its Media Analysis API. So now, the various audio processing capabilities of Audiologger are now present as Media Analysis plugins for Videologger.
