- The design goals of this code are:
- - Very fast algorithm
- - SIMD-friendly algorithm
- - Low memory requirement
- - Good *perceptual* quality (and not best SNR)
-
- Warning: This resampler is relatively new. Although I think I got rid of
- all the major bugs and I don't expect the API to change anymore, there
- may be something I've missed. So use with caution.
-
- This algorithm is based on this original resampling algorithm:
- Smith, Julius O. Digital Audio Resampling Home Page
- Center for Computer Research in Music and Acoustics (CCRMA),
- Stanford University, 2007.
- Web published at http://www-ccrma.stanford.edu/~jos/resample/.
-
- There is one main difference, though. This resampler uses cubic
- interpolation instead of linear interpolation in the above paper. This
- makes the table much smaller and makes it possible to compute that table
- on a per-stream basis. In turn, being able to tweak the table for each
- stream makes it possible to both reduce complexity on simple ratios
- (e.g. 2/3), and get rid of the rounding operations in the inner loop.
- The latter both reduces CPU time and makes the algorithm more SIMD-friendly.
