Mapped meta-data sound-playback device and audio-sampling/sample-processing system usable therewith
First Claim
1. An audio-sampler/sample-processor for preparing audio units for playback in a sample-based sound-producing device, the sound-producing device having a plurality of operable, physical control elements each of which, when operated by a user, causes a sound to be generated based on an audio unit, the audio-sampler/sample-processor comprising:
- an input module for receiving an audio file;
an audio-unit extractor for defining a set of audio units, automatically, by sampling within the input audio file, the audio-unit extractor itself setting the start and end points of each audio unit of said set of audio units;
an analyzer for analyzing said audio units, automatically, to determine the acoustic properties thereof and for defining data descriptive of the determined acoustic properties of each audio unit; and
a mapping module for defining, automatically, a mapping of extracted audio units to the physical control elements of the sample-based sound-producing device, said mapping being dependent on at least part of said data, determined by the analyzer, descriptive of the acoustic properties of the extracted audio unit and on a mapping function defining a condition holding on audio-unit meta-data;
wherein the audio-sampler/sample-processor is configured such that, when coupled to said sample-based sound-producing device, an user operation of one of said physical control elements of the sample-based sound-producing device causes an output of sound corresponding to an extracted audio unit mapped, by the mapping module, to the one of said physical control elements.

Abstract
Audio samples corresponding to audio extracts or whole audio titles are automatically mapped to triggers 12 in a playable sound-producing device 1, the mapping being dependent on the meta-data associated with the audio samples. Thus, a user can play the sound-producing device and generate sounds derived from his favorite audio titles. It is possible to define different mappings between the audio samples and the playable domain of the sound-producing device: an audio sample selector 50 can select between different possible samples for playback by comparing the audio properties of the samples and the play-mode and/or characteristics of the user'"'"'s performance. An audio sampler/sample-processor 70 can automatically extract segments of an audio source file and map them to triggers in the sound-producing device 1.
