LOW BAND BANDWIDTH EXTENDED |
摘要 |
Apparatus comprising: an input amplitude and phase calculator configured to determine at least one amplitude value and phase value dependent on a first audio signal; a synthesis amplitude calculator configured to synthesize a further amplitude value associated with each amplitude value dependent on a determined harmonic shaping function; a synthesis phase calculator configured to synthesize a further phase value associated with each phase value; and a signal synthesizer configured to generate a bandwidth extension signal dependent the further amplitude value and the further phase values. |
