Gapless playback is the uninterrupted playback of consecutive audio tracks, such that relative time distances in the original audio source are preserved over track boundaries on playback. For this to be useful, other artifacts (than timing-related ones) at track boundaries should not be severed either. Gapless playback is common with compact discs, gramophone records, or tapes, but is not always available with other formats that employ compressed digital audio. The absence of gapless playback is a source of annoyance to listeners of music where tracks are meant to segue into each other, such as some classical music (opera in particular), progressive rock, concept albums, electronic music, and live recordings with audience noise between tracks.

InactiveUS7448062B1Limited playback timeTimely controlMultiple digital computer combinationsTwo-way working systemsSoftware architectureData transport
A software architecture and control protocol that provides seamless playback of multiple clips of media data across a data network. Conventional server-based data network architecture where playback logic resides on the servers does not provide the capability of seamless playback of multiple clips stored in different servers. The present invention allows users to specify a playlist and provides control on the client with the implementation of a “client pull” data transport model. According to the present invention, the playlist is translated into a plurality of frame accurate requests, which are sent from the client to the servers one request at a time. The servers, upon receiving the requests, retrieve the corresponding frames of media data and transmit the media data back to the client. In this way, the present invention allows a user-interface to provide seamless playback of multiple clips that reside on different servers on the client workstation.

Adaptive and seamless playback buffer adjustment for streaming content
A source device executing the application can transmit the streaming content to the playback device. The size of the buffer can be changed during the playback of streaming content. To perform the change seamlessly, embodiments can cause the application to provide the streaming content at an increased or decreased rate, depending on how the size of the playback buffer is to be changed. The new buffer size (i.e., smaller or larger amount) can provide improved playback of the streaming content, e.g., based on a latency-reliability tradeoff as determined using various factors (e.g., quality of connection between the devices). The changed rate for providing the streaming content can be achieved by slowing down or speeding up a clock signal that is provided to the application.

The present invention is a method for enhancing playback of digital audio data by playing sound effects stored in a digital audio player's memory. The sound effects are preferably loaded into a playback memory just before an MPU of the player starts to perform a task that normally results in a silent processing delay, such as locating digital audio data. By parallel processing a sound effect with a time consuming task performed by the MPU, the processing delay is not noticed by a user. In addition to filling an otherwise silent interval of time with some sort of entertainment, the sound effects can be used to emulate some of the sounds made by a vintage juke box, such as the crackling of a needle on a record. In an alternative embodiment, the sound effects are stored in a song database such that there can be particular sound effects that are used when a particular song database is to be accessed. For seamlessly playing a song right after a sound effect, the digital audio data of a song selection can be streamed to the same playback memory that is used for playback of the sound effect.
