Abstract
Abstract An audio processing system comprises an editor system for converting a received audio sound recording into digital data blocks, where each data block represents a corresponding portion of the sound recording during a predetermined time interval. The data blocks are stored as a consecutive sequence representing the sound recording. A display circuit is provided for displaying the data blocks as a timed based graphical representation to a user. The sound recording is displayed for editing by converting the received sound recording into digital data blocks, displaying an axis representing time, displaying a graphical representation of the digital data adjacent to the time axis corresponding to the relative time position of a corresponding sound recording portion in that time period, and displaying at least one user locatable mark on the time axis representing a time point of the sound recording.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
60 words
An audio processing system comprising means for converting a received audio sound recording into digital data blocks, each data block representing a corresponding portion of said sound recording during a predetermined time interval, means for storing said data blocks as a consecutive sequence representing said sound recording, and means for displaying said data blocks as a time based graphical representation.
Claim 2
Dependent Claim
60 words
An audio processing system comprising means for converting a received audio sound recording into digital data blocks, each data block representing a corresponding portion of said sound recording during a predetermined time interval, means for storing said data blocks as a consecutive sequence representing said sound recording, and means for displaying said data blocks as a time based graphical representation.
Claim 3
Dependent Claim
35 words
An audio processing system according to Claim 1 further including means for receiving input commands for altering said sequence of digital data blocks and means for altering said sequence in response to said input commands.
Claim 4
Independent Claim
98 words
A method of processing a received sound recording received over a time period comprising the steps of: converting the received sound recording into digital data blocks, each data block representing a corresponding portion of said sound recording during a predetermined time interval; displaying an axis representing time; displaying a graphical representation of said digital data adjacent the time axis corresponding to the relative time position of a corresponding sound recording portion in said time period; and generating and displaying user locatable marks on said time axis representing selected time points of said sound recording during said time period.
Claim 5
Independent Claim
98 words
A method of processing a received sound recording received over a time period comprising the steps of: converting the received sound recording into digital data blocks, each data block representing a corresponding portion of said sound recording during a predetermined time interval; displaying an axis representing time; displaying a graphical representation of said digital data adjacent the time axis corresponding to the relative time position of a corresponding sound recording portion in said time period; and generating and displaying user locatable marks on said time axis representing selected time points of said sound recording during said time period.
Claim 6
Dependent Claim
18 words
A method according to claim 3 wherein said graphical representation is a representation of the sound recording amplitude.
Claim 7
Dependent Claim
18 words
A method according to claim 3 wherein said graphical representation is a representation of the sound recording frequency.
Claim 8
Independent Claim
24 words
A method according to any one of claims 3 to 5 further including the step of displaying a textual list of said locatable marks.
Claim 9
Dependent Claim
46 words
A method according to Claim 6 wherein said step of generating and displaying the textual list of said marks includes the generating and displaying of associated operator input editing command that is to be executed on the sound recording at the times represented by the marks.
Claim 10
Independent Claim
38 words
A method according to any one of claims 3 to 7 further including the step of displaying a second sound track as a graphical representation of digital data representing a second sound recording adjacent a second time axis.
Claim 11
Dependent Claim
33 words
A method according to claim 8 wherein said step of displaying the textual list of said time marks includes the displaying of second time marks representing time points on the second time axis.
Claim 12
Independent Claim
23 words
A method according to any one of claims 7 to 9 wherein said editing commands include inserting a portion of a sound recording.
Claim 13
Independent Claim
23 words
A method according to any one of claims 7 to 10 wherein said editing commands include deleting a portion of a sound recording.
Claim 14
Independent Claim
23 words
A method according to any one of claims 7 to 11 wherein said editing commands include moving a portion of a sound recording.
Claim 15
Independent Claim
24 words
A method according to any one of claims 7 to 12 wherein said editing commands include copying of a portion of a sound recording.
Claim 16
Independent Claim
44 words
A method according to any one of claims 7 to 13 wherein said portion of said sound recording for said editing command is indicated by time marks on the respective time axes for the sound recording that is the object of the editing command.
Claim 17
Independent Claim
46 words
A method according to any one of claims 7 to 14 wherein said time marks can be designated as being fixed at a specified time on the time axis or can be designated as fixed at a specified point in the sequence of digital data blocks.
Claim 18
Independent Claim
38 words
A method according to any one of claims 7 to 15 wherein said listing of time marks in the textual list includes a listing of the current time location of the respective marks on their respective time axes.
