Abstract: The invention concerns digital audio processing and in particular the detection of periods where samples can be deleted or repeated unobtrusively so as to change the average sample-rate or to provide time delay modification. Differences between succeeding sample values are evaluated and compared with a threshold and samples are deleted or repeated where two or more consecutive sample value differences are less than the said threshold value.

Abstract: A dedicated ratings input is presented for a portable media player. The input may take the form of a physical switch or pre-identified movements recorded by an accelerometer. Movement of the switch into one of the two positions sets a rating for the currently playing media file. The physical ratings switch is not used during the playing of media files for any purpose other than the rating of media files. This allows the user to alter the rating by moving the switch without requiring any visual interaction with the portable media player. Audio feedback is provided when the switch is used to change the ratings of the media files.

Abstract: A system provides music that matches the mood of an e-book when the e-book is read on an e-Reader. The system comprises several sub-components to calculate a user's average reading speed, analyze the e-book for moods, match music to each mood, track music played and purchased, record user's music preference, and play the matched music based on the user's music preference. The moods are indexed as adjectives, adverbs, and onomonopias. A change in mood triggers a change in music played in a wall-to-wall or movie mode. When a user does not have a music preference, the system chooses a default music based on genre, style, and mode based on the analyzed mood. When the system plays music in the movie mode to match a predetermined number of moods, the system fades the music to a pause equal to the predetermined number before resuming the music based on a current mood.

Abstract: Techniques pertaining to providing an appropriate recording mode to achieve optimum record data in accordance with the recording environment are described. In one embodiment, a current audio recording mode is initially selected to be one of a low sensitivity audio recording mode and a high sensitivity audio recording mode. A digital gain for digital audio recording data in the current audio recording mode is obtained. The current audio recording mode is automatically switched between the low sensitivity audio recording mode and the high sensitivity audio recording mode when the digital gain reaches a gain threshold.
