The SoX Resampler library
High quality, one-dimensional sample-rate conversion library
The SoX Resampler library `libsoxr' performs one-dimensional sample-rate conversion—it may be used, for example, to resample PCM-encoded audio. It aims to give fast and high quality results for any constant (rational or irrational) resampling ratio. Phase-response, preserved bandwidth, aliasing, and rejection level parameters are all configurable; alternatively, simple `preset' configurations may be selected. An experimental, variable-rate resampling mode of operation is also included. -

432Hz Batch Converter
Converts and re-encodes music to 432Hz
Most music is recorded in 440Hz. Many people claim that 432Hz resonates more with the heart whereas 440Hz resonates more with the brain, and that 432Hz music feels better. Try it yourself. Play a music in 440Hz and in 432Hz, and see which one you prefer. Most people choose the 432Hz version, and it's hard to go back to 440Hz. This application re-encodes your audio files while shifting the pitch to 432Hz. It uses a very high-quality pitch-shifting algorithm. Supports Windows (Win 7 SP1 or later) and Linux (all distros).
