Long Interpolation of Audio Signals Using Linear Prediction in Sinusoidal Modeling

Within the context of sinusoidal modeling, a new method for the interpolation of sinusoidal components is proposed. It is shown that autoregressive modeling of the amplitude and frequency parameters of these components allows us to interpolate missing audio data realistically, especially in the case of musical modulations such as vibrato or tremolo. The problem of phase discontinuity at the gap boundaries is also addressed. Finally, an original algorithm for the interpolation of a missing region of a whole set of sinusoids is presented. Objective and subjective tests show that the quality is improved significantly compared to common sinusoidal and temporal interpolation techniques of missing audio data.
