Song transition effects for browsing
First Claim
1. A method, performed by a device, for providing audio transitions between audio signals during audio browsing, comprising the steps of:
- the device associating a first browsing direction (A1), selected by a user via a control means, for transitioning from a current audio signal (S0) to a first alternative audio signal (S1) with a first transition effect template;
the device associating a second browsing direction (A2), selected by a user via a control means, which is different from the first browsing direction, for transitioning from the current audio signal to a second alternative audio signal (S2), with a second transition effect template, which is perceptually different from the first transition effect template, wherein the effect is selected from the group comprising simulated motion, simulated Dopper effect, stereo regeneration, spectral band replication, and reverberation; and
the device playing, in response to a browsing action in one of said browsing directions, a transition in which an exit segment (S0-out1, S0-out2), extracted from the current audio signal, and an entry segment (S1-in, S2-in), extracted from the alternative audio signal, are mixed in accordance with the associated transition effect template; and
the device subsequently playing the alternative audio signal from the end of the entry segment.

Abstract
In one aspect, a method of providing directive transitions between audio signals comprises associating a first/second browsing direction (A1, A2) with a first/second transition effect template. In response to a browsing action in one of said browsing directions, a transition is played in which an exit segment (S0-out1, S0-out2) and an entry segment (S1-in, S2-in) are mixed in accordance with the associated transition effect template. A further aspect proposes a method of transitioning between audio signals decoded from audio data including time markers encoded as audio metadata and indicating at least one section of the respective audio signal. The method includes retrieving time marking information in the audio data; extracting an exit segment (S0-out1, S0-out2) and an entry segment (S1-in, S2-in), wherein an endpoint of at least one of the segments is synchronized with a time marker; and playing a transition in which the exit and entry segments are mixed in accordance with a transition effect template.

9. A decoder for outputting audio signals by decoding audio entries in an ordered database permitting browsing in at least a first and a second browsing direction (A1, A2), wherein:
-
the first and second browsing directions are different, and are respectively associated with perceptually distinct first and second transition effect templates, wherein the effect is selected from the group comprising simulated motion, simulated Doppler effect, stereo regeneration, spectral band replication, and reverberation; and the decoder comprises one or more processors configured to react to a browsing action, initiated by a user via a control means, in one of said browsing directions by; initially outputting, from one or more of the processors, a transition signal segment comprising an exit segment (S0-out1, S0-out2), decoded from a current audio entry, and an entry segment (S1-in, S2-in), decoded from an alternative audio entry located in the concerned browsing direction in relation to the current audio entry, mixed in accordance with the associated transition effect template; and subsequently outputting, from one or more of the processors, an alternative signal decoded from the alternative audio entry. - View Dependent Claims (10)
