Bandwidth Enhanced Sinusoidal Modeling in Lemur
نویسندگان
چکیده
We present a system for sound modeling and synthesis that preserves the elegance and malleability of a sinusoidal model, while accommodating sounds with noisy (non-sinusoidal) components. We use an enhanced McAulay-Quatieri (MQ) style analysis that extracts bandwidth information in addition to the sinusoidal parameters for each partial. To produce noisy components, we synthesize with sine wave oscillators that have been modified to allow the introduction of variable bandwidth. The enhanced MQ analysis and the bandwidth-ehanced oscillators are implemented in Lemur, a widely distributed MacintoshTM program (free at the demonstration), which will be used to demonstrate the technique.

متن کاملA New Algorithm for Bandwidth Association in Bandwidth-Enhanced Additive Sound Modeling
The Bandwidth-Enhanced Additive Model represents sound as a collection of partials having sinusoidal and noise-like characteristics. Bandwidth Association is the process of constructing the bandwidth envelopes for partials in the bandwidth-enhanced model by associating noise energy not captured by conventional sinusoidal modeling processes. We present analytical methods for collecting and assoc...
متن کاملA hybrid sub-band sinusoidal coding scheme
This paper describes a hybrid sub-band speech coding scheme based on sinusoidal coding and CELP. Purely voiced speech is encoded using sinusoidal coding techniques and phase information is selectively transmitted. For mixed and unvoiced speech, the lower band is processed by sinusoidal coding algorithms while the upper band is encoded using CELP. To accommodate the extra bandwidth required by t...
متن کاملSound Morphing using Loris and the Reassigned Bandwidth-Enhanced Additive Sound Model: Practice and Applications
The reassigned bandwidth-enhanced additive sound model is a high-fidelity representation that allows manipulations and transformations to be applied to a great variety of sounds, including noisy and nonharmonic sounds. Combining sinusoidal and noise energy in a homogeneous representation, the reassigned bandwidth-enhanced model is ideally suited to sound morphing, and is implemented in the open...
