Hello all, Release 1.2.0 of libzita-resampler now include the 'zretune' app which resamples an audio file by (the inverse of) a ratio given in cents. The output file will have the same nominal sample rate as the input. The effect is to change the pitch AND the lenght of the original file. For small pitch changes (+/- a semitone) the modified length of a sample probably won't matter much. For example zretune --cent 50 input.wav output.wav will result in a file that sounds a quarter tone higher and is about 1.5 percent shorter. Enjoy ! -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)
