Systems and methods for generating a playback-information display during time compression or expansion of an audio signal are provided. The system includes a processor that performs a method including displaying a first remaining playback-time associated with an audio file; adjusting the playback speed of the audio file during playback of the audio file; and, in response to the playback speed being adjusted, automatically displaying a second remaining playback-time associated with the audio file during playback of the audio file.

Systems and methods are presented for efficient cross-fading of compressed domain information streams on a user/client device. Exemplary systems may provide cross-fade between AAC/Enhanced AAC Plus information streams, between MP3 information streams, or between information streams of unmatched formats. These systems are distinguished in that cross-fade is directly applied to compressed bitstreams so a single decode operation is performed on the resulting bitstream. Thus, a set of frames from each input stream associated with the time interval in which a cross fade is decoded, and combined and recoded with a cross fade or other effect now in the compressed bitstream. Once sent through the client device's decoder, the user hears the transitional effect. The only input data that is decoded and processed is that associated with the portion of each stream used the crossfade, blend or other interstitial, and thus the vast majority of input streams are left compressed.

The present disclosure provides a method and a system for realizing intelligent matching and adding of rhythmic tracks. In one example, a method is provided, including: pre-storing a plurality of music elements; generating a rhythmic track library according to the plurality of music elements, the rhythmic track library including a plurality of rhythmic tracks based on the plurality of music elements; detecting a BPM of original music, and calculating a time interval between every two beats based on the detected BPM of the original music; selecting one or more rhythmic tracks from the rhythmic track library, and assigning a time parameter to the one or more rhythmic tracks based on the time interval so as to match the rhythm of the original music; and adding the one or more rhythmic tracks assigned with the time parameter into the original music so as to combine with the original music and play.

Techniques are disclosed relating to determining composition rules, based on existing music content, to automatically generate new music content. In some embodiments, a computer system accesses a set of music content and generates a set of composition rules based on analyzing combinations of multiple loops in the set of music content. In some embodiments, the system generates new music content by selecting loops from a set of loops and combining selected ones of the loops such that multiple ones of the loops overlap in time. In some embodiments, the selecting and combining loops is performed based on the set of composition rules and attributes of loops in the set of loops.

Techniques are provided for generating an output file. One technique involves the steps of generating audio or MIDI content blocks from one or more musical performances; receiving an input file having audio or MIDI music content; generating a harmonic chord map for the input file; using the harmonic chord map to automatically select a subset of the audio or MIDI content blocks, and generating the output file by combining the selected subset of content blocks and the input file. This technique may enable the creation of unique and new musical accompaniments by re-purposing audio or MIDI content from back catalogs and/or out-takes of musical works. The new arrangement may be provided in multiple music styles, genres, or moods and may contain performances from multiple musical instruments, which may be pre-recorded from live instrument performances and/or of MIDI generated musical content.

Sound equipment includes: a beat position acquiring unit configured to analyze a beat position of music piece data to be reproduced or acquire an analysis result; and a beat position displaying unit configured to display a scale of a differential numerical value of the number of beats in a plus direction and a minus direction of the music piece data with reference to a currently reproduced position of the music piece data.

An intuitive music composition game platform with various modes of operation in a single reader system and a music mash up collectable card game and method using cards with tags and unique identifications. A single reading platform includes a cover for card storage and for supporting a smart device platform for reading many Near Field communication (NFC) embedded cards, with stacking features and colored light indicated input lanes selection for user identification and selection. Various game modes include individual, studio mix, party modes game play features in music mash up collectable card games, which may be used together with or independent of accessory devices as controllers, or smart device user interfaces with Bluetooth™ or Wi-Fi for communicating user selection and operation.

Disclosed herein is a method for facilitating creating of music in real time by multiple users, in accordance with some embodiments. Accordingly, the method comprises receiving first music segment selections from a first user device, receiving second music segment selections from a second user device, transmitting the first music segment selections to the second user device, and transmitting the second music segment selections to the first user device. Further, each of the first user device and the second user device is configured for retrieving the first music segments, retrieving the second music segments, determining a universal time, synchronizing the second music segments with the first music segments to a common musical beat based on the universal time, mixing the second music segments with the first music segments based on the synchronizing, and generating a mixed music comprising the first music segments and the second music segments based on the mixing.
