Various embodiments are directed to systems and methods for checking in at a business with a mobile computing device. For example, the mobile computing device may receive via a data network, location information for a venue. The mobile computing device may also determine whether a location of the mobile computing device is available. Conditioned upon the location of the mobile computing device being available, the mobile computing device may determine whether the location of the mobile computing device is within a threshold distance of the venue. Conditioned upon the location of the mobile computing device being within the threshold distance of the venue, the mobile computing device may send a check-in message to a server. The check-in message may indicate that the user of the mobile computing device is at the venue.

Automated user check-in utilizing mobile computing devices

A system and method for performing echo suppression on a server in browser-based online audio conferences without downloading or installing software on a participant's computing device is disclosed. Streams of audio communication data from the participants in an audio conference are received at the server. An echo suppression application determines the first party that speaks by analyzing the streams to locate speech data, and assigns that party as the 'owner' of the audio channel. The speech data is sent to the other participants in the conference. The application then determines whether newly received audio from the owner of the channel is new speech; if so, then the party remains the owner of the channel, and the new speech data is also sent to the other parties in the conference. The channel is surrendered if no new speech is received from the owner in a defined period, and the next party that speaks becomes the new owner of the channel. The other audio data from the participants is replaced by silence.
