Abstract

A computer-implemented method and system are provided for profiling or analyzing audio data based on an audio parameter. The audio data is divided into audio data into segments. Each segment is characterized by the audio parameter in a defined range. Effects are selected according to the segments meeting criteria for the audio parameter of the effects. A media presentation is authored or generated using the selected effects.

Claims

1. A computer-implemented method, comprising:

analyzing audio data based on an audio parameter;

dividing the audio data into segments, wherein each segment is characterized by the audio parameter in a defined range;

selecting effects according to the segments meeting criteria for the audio parameter of the effects; and

generating a media presentation using the selected effects.

2. The computer-implemented method of claim 1, wherein the audio parameter is selected from the group comprising:

beats per minute, rhythmic strength, harmonic complexity, and square root of the arithmetic mean of the square of density variations (RMS) strength.

3. The computer-implemented method of claim 1, wherein the dividing step is based on a range of the audio parameter.

4. The computer-implemented method of claim 1 further comprising the steps of:

associating each of the segments with a segment profile, the segment profile including the defined range of the audio parameter for each segment;

defining an audio requirements profile for each of the effects, the audio requirements profile including the criteria for the audio parameter;

comparing the segment profile for each of the segments to the audio requirements profile for each effect; and

determining whether the segment profile for each of segments meets the criteria for the audio parameter in the audio requirements profile.

5. The computer-implemented method of claim 4, wherein the criteria is an acceptance range.

6. A computer-implemented method, comprising:

analyzing audio data based on an audio parameter;

dividing the audio data into segments, wherein each segment is characterized by the audio parameter in a defined range;

linking an audio requirements profile of each of one or more effects to an audio parameter;

adjusting the one or more effects based on the audio parameter; and

generating a media presentation using the adjusted one or more effects.

7. The computer-implemented method of claim 6, wherein the audio parameter is selected from the group comprising:

beats per minute, rhythmic strength, harmonic complexity, and square root of the arithmetic mean of the square of density variations (RMS) strength.

8. The computer-implemented method of claim 6, wherein the dividing step is based on a range of the audio parameter.

9. The computer-implemented method of claim 6, wherein the step of adjusting further comprises adjusting one or more of the transition duration, effect duration, in points, and out points of the one or more effects.

10. A computer-implemented system, comprising:

memory configured to store audio data; and

one or more processors configured to analyze the audio data based on an audio parameter and divide the audio data into segments, wherein each segment is characterized by the audio parameter in a defined range,

the one or more processors further configured to select effects according to the segments meeting criteria for the audio parameter of the effects and generate a media presentation using the selected effects.

11. The computer-implemented system of claim 10, wherein the audio parameter is selected from the group comprising:
