Sentence examples for transform audio from inspiring English sources
In this paper, it deals with the correlation of neighboring parameters in the transform audio coding and some basic rules are designed to help with selecting the proper context model for the adaptive arithmetic coding.
As with most of the transform audio coding, G.719 uses modified discrete cosine transform (MDCT) to realize the time-frequency transform and to avoid artifacts stemming from the block boundaries.
The look-back memory elements are first constructed by applying the de-harmonizing predictor to the input signal, then the prediction residual is encoded and decoded by transform audio coding.
The subband or transform audio coding schemes primarily exploit the destination (human ear) model; the psychoacoustic model tells us where signal distortions (quantization) are allowed such that these are inaudible or least annoying.
In Figure 1, T 0) represents no context, T(1) = A or B, and T(2) = A or B. A represents the context in the frequency domain, while B represents the context in the time domain, and they correspond with the quantized parameters in the transform audio codec.
MixTrans is a mixture-structured bias voice transformation technique in the cepstral domain, which allows a transformed audio signal to be estimated and reconstructed in the temporal domain.
The team at SpareMin has tackled the problem with Headliner, a browser-based product for transforming audio clips into videos.
In our implementation, the magnitude of fast Fourier transform of audio signal was extracted every 1,024 samples with 512 samples in frame overlapping.
The majority of the algorithms described in the literature involve an initial data reduction step, transforming the audio signal into an onset-detection function (ODF), which is a representation of the audio signal at a much lower sampling rate.
All audio files were encoded to 16 bits at 16 kHz in Matlab (Mathworks, Natick, MA), and transformed into audio signals by a soundcard (Creative SoundBlaster, Milpitas, CA), and played through headphones (Koss UR29, Milwaukee, WI).
The watermark embedding procedure transforms the audio signal using DWT and SVD, embeds the bits of a binary image watermark in appropriate locations in the transformed signal, and finally produces a watermarked audio signal by performing inverse SVD and DWT operations.
