Patent number: 8635532Abstract: Exemplary embodiments of methods to automatically correct timing of recorded audio in GUI are summarized here. One or more controls to adjust resolution of timing and degree of correction for the audio are displayed. The resolution of timing relates to heats on a grid and is affected by the degree of correction. The degree of correction is mapped to a time interval at each beat along the grid. Next, a user manipulation of one or more controls selecting a resolution and a degree of correction is received. Correction of timing is performed according to the selected resolution and degree of correction. Correcting of timing may include aligning a transient of the audio to the beat by compressing or stretching a portion of the audio. Compressing or stretching the portion of the audio depends on a length of the portion relative to a distance between adjacent beats.Type: GrantFiled: October 5, 2009Date of Patent: January 21, 2014Assignee: Apple Inc.Inventors: Gerhard Lengeling, Sol Friedman

Patent number: 7514620Abstract: A method and apparatus for shifting pitches of audio signals to achieve desired pitch relationships between the audio signals. Two or more audio signals are received. The audio signals may be in either a digital or analog format. One of the input audio signals is selected to be a reference signal. For each of the other audio signals, the pitch of the other audio signal is compared with the pitch of the reference signal to determine a relative pitch relationship. For each of the other signals, an adjustment is determined to bring the relationship to a desired pitch relationship. Based on the adjustment, the pitch of at least one of the audio signals is adjusted to achieve the desired pitch relationship between the audio signals.Type: GrantFiled: August 25, 2006Date of Patent: April 7, 2009Assignee: Apple Inc.Inventors: Josephine Friedman, legal representative, Hanns-Christof Adam, Steffan Diedrichsen, Sol Friedman

Patent number: 7425674Abstract: A method and apparatus implement time compression and expansion of audio data, with dynamic tempo change during playback. Dynamic changes in tempo are implemented at specific points in the audio signal corresponding to local minimums in the fade-in and fade-out characteristics of the compression/expansion scheme. An audio signal is marked to define temporal slices of audio data. Mark positions may be selected to minimize significant transient activity midway between consecutive marks. Fade-in and fade-out functions are associated with the leading side and trailing side, respectively, of each mark, creating a series of cross-fading “mounds” with peaks at each mark. When a tempo change is requested (e.g., a user selects a new tempo value in a user interface), the tempo change is delayed until the start of the next “mound” (i.e., the next fade-in). Thus, despite the tempo change, each mound uses a contiguous set of audio data, preventing the clicks and pops associated with skips in the audio’ data.Type: GrantFiled: February 13, 2007Date of Patent: September 16, 2008Assignee: Apple, Inc.Inventors: Christopher Moulios, Sol Friedman

Patent number: 7250566Abstract: The invention is directed to a method and apparatus for evaluating and correcting rhythm of audio data. Embodiments of the invention are capable of obtaining preferred rhythm in audio data, and strategically correcting the portions of audio data resulting an enhancing rhythm. A system embodying the invention may detect each transient in audio data, compute an ideal time for the transient and determine the time deviation from the expected ideal time. The system may correct for the time of the transient by altering the audio data before or after the transient. The system utilizes one or more methods to correct for the timing while preserving the audio quality of the signal.Type: GrantFiled: August 1, 2006Date of Patent: July 31, 2007Assignee: Apple Inc.Inventors: Gerhard Lengeling, Sol Friedman

Patent number: 7233832Abstract: Systems implementing the invention allow a user to time stretch an audio track without changing the pitch of the sound, and to produce optimal audible qualities of the output signal. The approach utilized in the invention relies on providing several time stretching methods, each one of which is selected based on one or more criteria of the audio data properties. One method relies on crossfading pairs of segments of audio data while running one segment backward every other repetition. The second time stretching method detects inaudible segments and inserts longer periods of audible data within those segments. The third method utilizes a reverb to create a reverb segment that is played after the original segment.Type: GrantFiled: April 4, 2003Date of Patent: June 19, 2007Assignee: Apple Inc.Inventors: Sol Friedman, Chris Moulios
