Audio reproduction apparatus, method, computer program

An audio reproduction apparatus for use during sports training, the audio reproduction apparatus comprising:

• a tempo unit which generates a selected output tempo;
• an audio conditioning unit which generates an output audio signal, the audio conditioning unit including:
• a tempo calculation unit which calculates an input tempo of an input audio signal,
• a tempo comparing unit which compares the calculated input audio tempo and the selected output tempo, in response to the input audio tempo differing from the selected output tempo by more than a preselected threshold, the tempo comparing unit generates an output signal requesting a different audio input signal,
• an audio processing unit which modifies the input audio signal to have a tempo closer to the selected output tempo and with the modified input signal having a pitch substantially equal to a pitch of the input audio signal, the audio processing unit:
• dividing the input audio signal into audio segments,
• adjusting a temporal interval between adjacent audio segments to modify the input audio segment to assume a tempo closer to the selected tempo,
• repeating at least some of the audio segments modifying the tempo of the input audio signal to be closer to the selected output tempo;
• and,
• an audio output by which the modified input audio signal is output as an output audio signal for a sound production means.
