Abstract: An energy-based pattern recognition algorithm receives the input frames of an audio signal and a test frame sequence and returns a best match in the audio signal to the given test frame sequence. The energy of each input frame is computed, and input frames for which the energy is within a predetermined degree of closeness to the local maximum energy within the test frame sequence are identified as probable matches. Probable matches are then eliminated if the respective probable match does not correspond to a local maximum within a respective neighborhood of adjacent frames. The difference between overall energy for frames neighboring the remaining probable matches and the test frame sequence is computed as a percentage, with the minimum percent deviation in energy from the test frame sequence being returned as the best pattern match. Local signal characteristic matching may be employed to refine matching.

Abstract: A digital music player includes an audio file selector that selects a subsequent audio file to play from a collection of audio files based upon a desired relationship between an audio characteristic of a current audio file and an audio characteristic of the subsequent audio file.

The desired relationship can be a specified correspondence between a key or tempo of the current audio file and a key or tempo of the subsequent audio file. The audio selector is preferably implemented through a software macro which is downloaded into an existing digital music player.

Abstract: Methods and apparatus provide for a clip-beat aligner that identifies musical beats in an audio file. An editing mode is provided to associate the audio file with a media segment according to a timeline. The clip-beat aligner aligns a boundary of the media segment with a musical beat on the timeline.

To align a boundary of each media segment with a musical beat, the clip-beat aligner identifies a musical beat that is proximate to the position of the media segment's boundary. The clip-beat aligner then aligns the media segment's boundary with the proximate musical beat by, if necessary, automatically trimming the media segment's duration such that the media segment's boundary occurs at the same moment in time as the proximate musical beat.

Abstract: A method of generating a tone waveform using a CPU is provided which prevents or minimizes operational delays of other software processing that is executed concurrently with tone waveform generating processing on a multitask basis. The CPU collectively calculates 128 (one block of) tone waveform sample values each corresponding to a sampling clock pulse, and transmits the calculated tone waveform sample values to a reproduction section in response to a predetermined calculation triggering clock pulse generated every 128 samples. When sufficient processing capability of the CPU performing the multitask is available for the waveform sample calculation, tone waveform sample values for one or more following blocks are also calculated and stored in a sample buffer in advance. When the CPU is too busy with the other software processing to execute the waveform sample calculation, it is just sufficient that the previously stored tone waveform sample values be read out to be transmitted to the reproduction section.
