Library for audio resampling
audio, c, c++, embedded, resampling
Solution
This page lists a bunch of options.
Formatted exert, for the records. Please check out the above link for important details and licence information:
- `libresample` and `sndfile-resample` (from `libsamplerate`) (in the Planet CCRMA Distribution).
- `libsoxr`, the SoX resampler library
- `ssrc` (from Shibatch)
- There is a project combining `ssrc` and `sox`
- New in 2016 is a Python (Cython) implementation: resampy
- Brick (on Github).
- Smarc, available as a command-line program or C library.
- The resample software package contains free sampling-rate conversion and filter design utilities written in C.
- Older Version for NeXT Computers.
- Original 1983+ source for the PDP KL-10.
- Erik de Castro Lopo's "SecretRabbitCode" `libsamplerate`
`libresample` based on `resample-1.7P
`libresample4j` is a Java port of `libresample`.
- Open Source Audio Library Project (OSALP) contains a C++ class based on `resample`.
- The Speex speech coder/decoder.
- More at another large list of implementations and their relative performance.
Problem
In an embedded (Windows CE) C++ project, I have to resample an arbitrary sample-rate down (or up) to 44100 Hz. Is there a free and portable C/C++ library for audio resampling?
