Classes for reading and writing Wav files in C++.
- Read or write incrementally (frame by frame), or all at once
- Support for 8/16/24/32-bit int samples, or 32/64-bit float samples
- Conversion to/from 16-bit int format, while reading or writing
- In-Memory conversion to/from 16-bit int format
- Little-Endian; supports iOS, Android NDK, Windows, and OSX (post-PowerPC)
