    摘要: Methods, systems and computer readable media for altering an audio output are provided. In some embodiments, the system may change the original frequency content of an audio data file to a second frequency content so that a recorded audio track will sound as if a different person had recorded it when it is played back. In other embodiments, the system may receive an audio data file and a voice signature, and it may apply the voice signature to the audio data file to alter the audio output of the audio data file. In that instance, the audio data file may be a textual representation of a recorded audio data file.

    摘要: A remastering system may up-convert the sample rate of an input sampled value digital program signal (DPS), generate harmonics of the up-converted signal at the sample rate of the up-converted signal, add the harmonics to the up-converted signal, and filter the resulting signal to produce a remastered signal having enhanced content compared to the original signal. The remastering system may further include a frequency-specific time alignment corrector and equalizer that delays lower frequencies of the input signal with respect to higher frequencies of the input signal to produce an alignment of signal components that is truer to the original recorded sound. The source of the input signal may be an audio CD.

    摘要: A method of setting an equalizer so as to enlarge a sound field in reproducing an audio file and a method of reproducing an audio file thereby, includes: dividing an input audio file into segments with a predetermined time length; extracting an audio feature value for each segment; determining equalizer information for reproducing each segment by the use of the extracted feature value; and determining an equalizer sequence for the audio file by the use of the determined equalizer information of each segment. Since the equalizer setting information can be automatically changed without user manipulation, the user can listen to an audio file of which the sound field is dynamically enlarged.

    摘要: A multi-channel audio reproducing device of a type converting, from digital to analog, multi-channel audio data whose channels are different in sampling frequency by using DACs fewer in number than the channels, and reproducing the same. A decoding part executes sampling frequency conversion with respect to the audio data in at least one channel so that a sampling frequency thereof coincides with that of the other channels. A DAC part converts, from digital to analog in a time sharing manner, the audio data in the plurality of channels equalized in sampling frequency.
